| (54) | Jacquard shadow velours |
| (57) The invention relates to a jacquard shadow velour comprising binding warp threads,
tension warp threads, differently colored weft threads, pile naps in an m/n W-pile
through weave (with n>m and m>2 and n>5) and lying colored pile areas. In lying pile
areas, at least first groups of at least three weft threads are surrounded by one
of the pile naps. In the lying pile areas, further at least second groups of at least
three weft threads are surrounded by one of the pile naps. Each second group comprises
at least one weft thread which is also comprised by a first group, as well as at least
one weft thread which is not comprised by this first group. Each first group comprises
at least one weft thread which is also comprised by a second group, as well as at
least one weft thread which is not comprised by this second group. |
[0001] This invention relates to a jacquard shadow velour comprising binding warp threads, tension warp threads, differently colored weft threads, pile naps in an m/n W-pile through weave (with n>m and m>2 and n>5) and lying colored pile areas.
[0002] This invention also relates to various methods for manufacturing such a jacquard shadow velour.
[0003] A jacquard shadow velour of the above-mentioned type is known from European patent 0 380 808.
[0004] In this known shadow velour, pile areas of mutually different directions have mutually different colors. This is achieved by giving three successive weft threads three mutually different colors. Thus identical groups of three weft threads different in color are formed. Of these groups, depending on the pile direction, either in each case a first weft thread is provided above a plane formed by the tension warp threads, while the third weft thread of the groups is provided under the respective plane, or in each case the first weft thread of the groups is provided under the respective plane, while the third weft thread is provided above the respective plane. As a result of all this, in a lying pile area of a first pile direction, the color of the first weft threads of the groups is visible, while the color of the third weft threads of the groups is not visible, whilst in a pile area of a second pile direction, which is directed opposite to the first pile direction, the color of the third weft threads of the groups is visible, while the color of the first weft threads of the groups is not visible.
[0005] A disadvantage of the known fabric is that the possible color variations are limited and are always directly coupled to the direction of the pile.
[0006] The object of the invention is to provide a fabric where similar, but also further-going color variations are enabled.
[0007] To that end, the jacquard shadow velour according to the invention is characterized in that in lying pile areas, at least first groups of at least three weft threads are surrounded by one of the pile naps; and that in the lying pile areas at least second groups of at least three weft threads are surrounded by one of the pile naps; wherein each second group comprises at least one weft thread which is also comprised by a first group, as well as at least one weft thread which is not comprised by this first group, and wherein each first group comprises at least one weft thread which is also comprised by a second group, as well as at least one weft thread which is not comprised by this second group.
[0008] The weave according to the invention thus makes it possible to give pile areas different colors. In particular, it is possible to give different pile areas a mutually different color. Further, it has been made possible to give pile areas having a mutually different pile direction mutually different colors.
[0009] According to a particular embodiment of the invention, it holds that the first groups are located in lying pile areas with a first pile direction and that the second groups are located in lying pile areas with a second pile direction which is opposite to the first pile direction. According to this variant, pile areas with a mutually different pile direction can be provided with different colors.
[0010] According to a possible further elaboration of this variant, it holds that each first group comprises a weft thread which lies directly next to a second group and that each second group comprises a weft thread which lies directly next to a first group.
[0011] Preferably, it holds in this variant that the color-determining weft threads of first groups from pile areas with the first pile direction per first group in each case have the same color or colors and that the color-determining weft threads of second groups from pile areas with the second pile direction per second group in each case have the same color or colors.
[0012] According to this embodiment, the color formation in a pile area is determined by the choice of color of the weft threads.
[0013] In particular, it holds that the color formation of a pile area with a first pile direction is determined by at least one color-determining weft thread of the first group, which color-determining weft thread lies on a pile side of the tension warp and which is not covered by a pile thread of a pile nap belonging to this first group, the color formation of a pile area with the second pile direction is determined by at least one color-determining weft thread of the second group, which color-determining weft thread lies on the pile side of the tension warp, and is not covered by a pile thread of a pile nap belonging to this second group and wherein the color formation of at least one pile area with the first pile direction differs from the color formation of at least one pile area with the second pile direction.
[0014] In this way, pile areas with the same pile direction will in each case have the same color. In particular, it holds, further, that the color-determining weft threads of first groups from pile areas with the first pile direction per first group in each case have at least one color which differs from the color or colors of the color-determining weft threads of second groups from pile areas with the second pile direction.
[0015] In this way, pile areas with a mutually different pile direction will also have mutually different colors.
[0016] According to a preferred embodiment of the jacquard shadow velour, it holds that the weft threads comprise adjacent groups of three consecutive weft threads, while these adjacent groups per adjacent group in each case comprise, in the same order, the same color of weft threads, and these adjacent groups do not coincide completely with the first groups mentioned and the second groups mentioned.
[0017] According to an alternative further elaboration of the weave according to the invention, the jacquard shadow velour is characterized in that the pile threads in the direction of the weft threads comprise identical groups, located next to each other, of at least two pile threads having a mutually different color, while in a pile area with the first pile direction the pile naps are formed by in each case at least one same pile thread of the groups of pile threads, so that the color of this pile area is determined by the color of this at least one the same pile thread and in a pile area with the second pile direction the pile naps are formed by in each case at least one same pile thread of the groups of pile threads, so that the color of this pile area is determined by the color of this at least one same pile thread.
[0018] According to this variant, the color formation in a pile area is therefore determined by the colors of the pile threads. In particular, it holds that the pile threads which do not form a pile nap in the pile areas are tied in in the web.
[0019] In this way, the colors of some pile threads will and those of other pile threads will not be visible.
[0020] According to an alternative embodiment of the jacquard shadow velour according to the invention, it holds that the first and second groups are located in pile areas with the same pile direction. For this variant, it holds that selected areas, independently of the direction of the pile, can be provided with mutually different colors. It is then also possible that a particular pile area is provided with a mixed color, while another pile area is provided with a pure color.
[0021] The invention also relates to a jacquard shadow velour of the type described in the preamble which is further characterized in that the pile threads comprise identical groups, located next to each other, of at least two pile threads with a mutually different color, while in a pile area with a first pile direction the pile naps are formed by at least one same pile thread of the groups of pile threads, so that the color of this pile area is determined by the color of this at least one same pile thread, and in a pile area with a second pile direction which is opposite to the first pile direction the pile naps are formed by at least one same pile thread of the groups of pile threads, so that the color of this pile area is determined by the color of this at least one same pile thread.
[0022] In this variant of the invention, it is possible to give mutually different pile areas mutually different colors. In that case, these different pile areas can have the same pile direction or different pile directions. The coloring of a pile area is therefore not necessarily related to the pile direction of the pile area in question. Thus, a jacquard shadow velour has been obtained, where a great many different color variations of the pile areas are possible. In particular, the identical groups of pile threads can comprise, for instance, five pile threads having mutually different colors. In this way, a particular pile area, independently of the pile direction, can be assigned five different colors at will. The invention also relates to a method for manufacturing a jacquard shadow velour comprising binding warp threads, tension warp threads, weft threads, pile naps in an m/n W-pile through weave (with n>m and m>2 and n>5) and lying colored pile areas, in which use is made of a double pile fabric weaving machine in which the binding warp threads are tied in by a shaft mechanism or at least two cam assemblies. Such methods are known per se. The tension warp threads are then tied in by a jacquard mechanism, whilst the pile warp threads are tied in by a shaft mechanism or at least two cam assemblies. According to the invention, however, it holds that the pile warp threads are tied in by a jacquard device. If such a method is used, jacquard shadow velours can be obtained with many color variants which may or may not coincide with the pile areas. In particular, it holds that the tension warp threads are also tied in by a shaft mechanism or at least two cam assemblies. It is also possible, however, that the tension warp threads are tied in by the jacquard device. Obtaining color variations is then possible.

[0024] Referring to Figs. 1a-1d, presently a first embodiment of a jacquard shadow velour according to the invention will be discussed.
[0025] The jacquard shadow velour is preferably manufactured on a double pile fabric weaving machine. On such a weaving machine, a fabric is woven which by means of knife is cut into two equal parts. This yields an upper article I and a lower article II. Both the upper article I and the lower article II comprise a jacquard shadow velour according to the invention.
[0026] Hereinafter, by jacquard shadow velour will be meant the upper article I. What holds true for the upper article I likewise holds true for the lower article II. For clarity, the lower and upper articles have only been partly separated from each other by means of the knife M. In the finished product, however, the upper article I and the lower article II will be completely separated from each other.
[0027] The jacquard shadow velour comprises binding warp threads BK, tension warp threads SK and pile naps PN. The pile naps PN are each formed from pile warp threads PK which have been cut through by means of the knife M. The pile naps are formed in an m/n W-pile through weave (with n>m and m>2 and n>5), with m=3 and n=6 in this example. Further, the jacquard shadow velour comprises lying colored pile areas. In Fig. 1a, a pile area is shown with a pile directed to the left, while in Fig. 1b a pile area is shown with a pile directed to the right.
[0028] It holds in lying pile areas that at least first groups of at least three weft threads (3, 4, 5) are surrounded by one of the pile naps (see Fig. 1a and 1c). It further holds that in lying pile areas at least second groups of three weft threads (2, 3, 4) are surrounded by one of the pile naps (see Fig. 1b and 1d). It further holds that each second group (2, 3, 4) comprises at least one weft thread (3, 4) which is also comprised by the first group (3, 4, 5) as well as at least one weft thread (2) which is not comprised by the first group (3, 4, 5), and wherein each first group (3, 4, 5) comprises at least one weft thread (3, 4) which is also comprised by a second group (2, 3, 4), as well as at least one weft thread (5) which is not comprised by this second group (2, 3, 4).
[0029] Further, it holds that in the web according to Figs. 1a to 1d that the first groups are located in lying pile areas with a first pile direction (see Fig. 1a) and that the second groups are located in lying pile areas with a second pile direction which is opposite to the first pile direction. It further holds in this example that each first group (3, 4, 5) comprises a weft thread (5) which lies directly next to a second group (2, 3, 4) and that each second group (2, 3, 4) comprises a weft thread (2) which lies directly next to a first group (3, 4, 5).
[0030] Further, it holds that the coloring of a pile area with a pile direction directed to the left (Fig. 1a) is determined by at least one color-determining weft thread (3) of, in each case, the first group (3, 4, 5), which color-determining weft thread (3) lies on a pile side PZ of the tension warp thread SK and is not covered by a pile thread PK of a pile nap PN belonging to this first group. This concerns the weft threads (3), since weft threads (4) are covered by the pile warp PK, whilst weft threads (5) are covered by the tension warp SK. As a result of all this, the color of a pile area with a pile directed to the left is determined by the color of the weft threads (3).
[0031] For the color formation of a pile area with a pile directed to the right (Fig. 1b), it holds that this is determined by at least one color-determining weft thread (4) of, in each case, the second group (2, 3, 4), which color-determining weft thread (4) is located on the pile side of the tension warp and is not covered by a pile thread PK of a pile nap PN belonging to this second group.
[0032] Further, the color formation of the pile area with a pile directed to the left differs from the color formation of the pile area with a pile directed to the right. This is achieved in that the weft threads (3), which determine the color of a pile area with a pile directed to the left (Fig. 1a), differ from the colors of the weft threads (4) which form the color of a pile area with a pile directed to the right (Fig. 1b).
[0033] In particular, it holds that the color-determining weft threads of groups from pile areas with the first pile direction per group have the same color. This means that the weft threads (3) have the same color.
[0034] Further, it also holds preferably that the color-determining weft threads of groups from pile areas with a pile direction directed to the right (Fig. 1b) per second group have the same color or colors. In the case of Fig. 1b, it is per second group only one weft thread that is color-determining. This concerns the weft threads (4). These weft threads therefore have preferably the same color, so that the pile area with a pile directed to the right will have a uniform color which corresponds with the color of the weft threads (4).
[0035] In particular, it holds that the color-determining weft threads of first groups from pile areas with the pile direction directed to the right per first group in each case have at least one color that differs from the color or colors of the color-determining weft threads of second groups from the pile areas with the second pile direction. In this case, this means that the weft threads (3) have a different color than the weft threads (4).
[0036] Preferably, it holds that the weft threads are tied in according to a 2/1 weave with the tension warp thread, as shown in Figs. 1a and 1b.
[0037] It also holds, preferably, that the weft threads are tied in according to a 1/1 or basket weave with the binding warp. In Figs. 1a and 1b, the basket weave is shown.
[0038] The web according to Figs. 1a and 1b can also be provided with an upright pile. Starting from the pile naps PN, as shown in Fig. 1a, an upright pile can be obtained by laying the weft threads (3, 6) on the side of the tension warp opposite the pile side. As will be set out in more detail hereinafter, as a result of this, in manufacturing such a weave, in addition to the pile warp, also the tension warp will have to be tied in by means of a jacquard mechanism.
[0039] Starting from the pile naps of Fig. 1b, an upright pile nap can also be obtained by, in this case, laying the weft threads (4) on a side of the tension warp SK remote from the pile side PZ. For this variant, too, it holds that during manufacture, the tension warp SK needs to be tied in by means of a jacquard mechanism
[0040] Referring to Figs. 2a.1 and 2b.2, presently an alternative embodiment of a web according to the invention will be discussed. For this embodiment too, it holds that the web in the lying pile areas comprises at least first groups of at least three weft threads ((3, 4, 5) for the first reed dent and (6, 1, 2) for the second reed dent) which are surrounded by one of the piles, and that in the lying pile areas at least second groups of at least three weft threads ((5, 6, 1) for the first reed dent and (2, 3, 4) for the second reed dent) are surrounded by one of the pile naps. Here, it holds further that each second group ((5, 6, 1) for the first reed dent; (2, 3, 4) for the second reed dent) comprises at least one weft thread ((5) for the first reed dent; and (2) for the second reed dent) which is also comprised by the first group, as well as at least one weft thread ((6, 1) for the first reed dent; (3, 4) for the second reed dent) which is not comprised by this first group. Further, it holds that each first group comprises at least one weft thread ((5) for the first reed dent and (2) for the second reed dent) which is also comprised by a second group ((5, 6, 1) for the first reed dent and (2, 3, 4) for the second reed dent), as well as at least one weft thread ((3, 4) for the first reed dent and (6, 1) for the second reed dent) which is not comprised by the second group ((5, 6, 1) for the first reed dent; and (6, 1) for the second reed dent). It further holds for the web, that the first groups are located in lying pile areas with a first pile direction (Figs. 2a.1 and 2a.2) and that the second groups are located in lying pile areas with a second pile direction which is opposite to the first pile direction (Figs. 2b.1 and 2b.2). It further holds again that each first group comprises a weft thread ((4) for the first reed dent and (1) for the second reed dent) which lies directly next to a second group ((5, 6, 1) for the first reed dent; (2, 3, 4) for the second reed dent) and that each second group comprises a weft thread ((6) for the first reed dent and (3) for the second reed dent) which lies directly next to a first group.
[0041] A difference with the embodiment according to Figs. 1a to 1d is therefore that the first and second groups for a particular reed dent according to the variant of Fig. 1, viewed in the warp direction, are shifted one weft thread with respect to each other, whilst in the web according to Figs. 2a.1 to 2b.2 it holds for a particular reed dent that the first groups, viewed in the warp direction, are shifted two weft threads with respect to each other. Color effects that can be achieved with the web according to Figs. 2a.1 and 2b.1, however, are comparable with color effects that can be obtained with the web according to Fig. 1. Thus, it holds for the pile direction according to Figs. 2a.1 and 2a.2 that the identically colored weft threads (3, 6) determine the color of the pile area, whilst in the pile area having the opposite pile direction according to Figs. 2b.1 and 2b.2 the identically colored weft threads (1 and 4) determine the color of the pile area.
[0042] When, for instance, the weft threads (3, 6) are colored red, the pile area with the pile direction according to Figs. 2a.1 and 2a.2 therefore obtains a red color. If it holds that the weft threads (1, 4) are each colored yellow, the pile area with the pile direction according to Figs. 2b.1 and 2b.2 thus obtains a yellow color. The color of the weft threads (2 and 5) is not visible in any pile area with a lying pile.
[0043] Referring to Figs. 3a-3c, presently an alternative embodiment of a web according to the invention is discussed. For this web, too, it holds that it is provided with an upper web I and a lower web II which are separated from each other by means of the knife 1 to obtain the end product. Both the upper web I and the lower web II consist of a jacquard shadow velour comprising binding warp threads BK, tension warp threads SK, differently colored weft threads (1, 2, 3, ...), pile naps PN in an m/n W-pile through weave (with m=3 and n=6) and lying colored pile areas.
[0044] The weave used for the binding warp threads, the tension warp threads, the weft threads and the pile naps is entirely analogous to that discussed in relation to Figs. 1 and 2. Supplemental to the weave of Figs. 1a and 1b, the weave according to Figs. 3a and 3b is provided with pile threads which in the direction of the weft threads comprise identical groups, located next to each other, of at least two pile threads PK1 and PK2 of a mutually different color. In this example, the pile thread PK1 has a red color and the pile thread PK2 has a blue color.
[0045] In the pile area with a pile directed to the left (Fig. 3a) the pile naps PN are in each case formed by at least one same pile thread of these groups of pile threads. This means that the color of this pile area is determined by the color of this at least one same pile thread PK1.
[0046] Further, the pile threads of these groups which do not form a pile nap in the pile area of Fig. 3 are tied in in the web. In the web with a pile directed to the left (Fig. 3a), this concerns the pile thread PK2 which, as desired, can be tied in in the upper web I or in the lower web II. In this example, both possibilities are shown in broken lines. The pile thread PK2 in this example is tied in basket weave. A 1/1 weave, however, is also possible. The effect thereof is that the color of the pile thread PK2 is not visible in a pile area with a pile direction directed to the left (Fig. 3a).
[0047] In a pile area with a pile direction directed to the right (Fig. 3a) the pile naps PN are formed by at least one same pile thread PK2 of the groups of pile threads (PK1, PK2), so that the color of this pile area is determined by the color of this at least one same pile thread PK2. In this example, the color of the pile area is therefore determined by the pile thread PK2. For the other pile thread PK1, it holds again that it is tied in in the upper web I or in the lower web II in a comparable manner as discussed in relation to Fig. 3a. The effect is that the shadow velour is provided with at least a first and second pile area (Fig. 3a and Fig. 3b, respectively) with a mutually different color, and mutually different lying pile directions, with the color of the first pile area (Fig. 3a) being determined by the first pile naps, and the color of the second pile area (Fig. 3b) being determined by second pile naps. In addition, it holds therefore that the first pile naps comprise pile threads PK1 with a color effect differing from the color effect of the pile threads (PK2) of the second pile areas. All this is achieved in that the first pile naps comprise at least one pile thread PK1 with a color different from the color or colors of the pile threads (PK2) of the second pile naps.
[0048] Obviously, it is also possible that the groups of pile threads comprise five pile threads PK1-PK5 (not shown). These pile threads can also have mutually different colors. The color of the pile area can then be determined, as desired, by one or more of these pile threads, by forming pile naps on the basis of a selection of these pile naps. The non-selected pile threads can then be tied in again as desired in the upper web or in the lower web. In the case where the identical groups of pile threads located next to each other comprise three pile threads PK1, PK2 and PK3 having mutually different colors, to each pile area, independently of the pile direction, a color can be assigned which corresponds with the color of the thread PK1, PK2 or PK3, or a mixed color consisting of the threads PK1, PK2; PK1, PK3; PK2, PK3; and PK1, PK2, PK3. Thus, six mutually different colors can be assigned to a pile area.
[0049] In Fig. 3c a pile area is shown with an upright pile. The upright pile in this example is formed by pile naps PN, which consists of the pile threads PK2. The pile thread PK2 is symmetrically tied in by the weft threads (1, 2, 3) for the upper web I and the weft threads (4, 5, 6) for the lower web II. Through this symmetrical weave, the pile nap formed will stand straight up. In the example of Fig. 3c, the identical groups of pile warp threads consist of PK1, PK2 and PK3.
[0050] In this example, the color effect of the pile warp threads PK1 and PK3 is not visible. In this example this is realized by tying in the pile thread PK1 in the upper web I, while the pile thread PK3 is tied in in the lower web II. It is obviously also possible to tie in both pile threads PK1 and PK3 in the upper web I or to tie in both pile threads PK1 and PK3 in the lower web II. It is also possible to tie in the pile thread PK3 in the upper web I, whilst the pile thread PK1 is tied in in the lower web II.
[0051] Further, referring to Figs. 4a, 4b and 4c, a third possible variant of the fabric according to the invention is shown.
[0052] The fabric according to Figs. 4a and 4b is again a jacquard shadow velour comprising binding warp threads BK, tension warp threads SK, weft threads (1, 2, 3, ...), pile threads PK and pile naps PN formed by these pile threads, in an m/n W pile through weave with m=3 and n=4. Further, the jacquard shadow velour is provided with lying colored pile areas.
[0053] Fig. 4a shows a pile area with a pile directed to the left, whilst Fig. 4b shows a pile area with a pile directed to the right. The weave according to Figs. 4a and 4b is a 3/6 W-pile through weave 1/2. The addition 1/2 means that in each case two weft threads are located on the pile side, whilst one weft thread is located on the back of the web, located opposite the pile side. This also appears from Figs. 4a and 4b, where twice as many weft threads are located on the pile side as on the back of the web. In this fabric, too, it holds that the pile threads PK1 and PK2 comprise identical groups, located next to each other, of two pile threads PK1 and PK2 with a mutually different color. Here too, it holds that in a pile direction with the pile directed to the left (Fig. 4a), the pile naps are determined, as desired, by the pile warp thread PK1, by the pile warp thread PK2 or by both pile warp threads PK1, PK2. In this example, the choice has been that in a pile directed to the left, the pile naps are formed by the pile warp threads PK2.
[0054] The pile warp thread PK1 can again as desired be tied in in the upper web I or in the lower web II. The result is that in this example the pile directed to the left takes the color of the pile warp thread PK2.
[0055] Also with a pile directed to the right (Fig. 4b), it holds that the pile naps PN can as desired be formed by the pile warp thread PK1, the pile warp thread PK2 or the pile warp threads PK1 and PK2. In this example, it has been chosen to have the pile naps PN formed by the pile warp thread PK1, whilst the pile warp thread PK2 is tied in in the lower web II. Because the pile naps are formed by the pile warp thread PK1, the area with a pile directed to the right will take the color of the pile warp thread PK1.
[0056] In this example, the pile warp thread PK2 is tied in in the lower web II. In this case too, the pile area with a pile directed to the left or a pile area with a pile directed to the right can, independently of the pile direction, be provided with colors of the pile thread PK1, PK2 or of a combination of the two pile threads PK1 and PK2.
[0057] A complication in the weave according to Figs. 4a and 4b is that, depending on the pile area, both the pile warp threads and the figure warp threads can be tied in with the weft thread in different ways. This means that both the pile warp threads and the figure warp threads must be tied in with the aid of a jacquard device. The binding warp threads BK can be tied in by means of shafts in a manner know per se, because the binding between the weft threads and the binding warp threads is independent of the pile area. In other words, the weave is the same over the entire width of the web.
[0058] Finally, in Fig. 4c it is also shown that it is also possible to provide the web according to Figs. 4a and 4b with an upright pile. In this example, the pile warp thread PK1 is tied in in the upper web, whilst by means of the pile warp thread PK2 pile naps are formed. The color of the pile area with an upright pile is therefore determined by the color of the pile warp thread PK2. In this example, the pile warp thread PK1 is tied in in the same manner as the figure warp thread FK. Further, it holds that the weave type of Fig. 4c is no longer a 1/2 weave but a 2/1 weave. Presently, in each case a weft thread (2, 5, 8) is located on the pile side, whilst the other weft threads are located on the back of the web.
[0059] In Fig. 5 a further variant of a web according to the invention is shown. Fig. 5 too shows a jacquard shadow velour according to a 3/6 W-pile through weave. In this weave, it holds that groups of three weft threads (1, 2, 3; 4, 5, 6) are formed, of which in each case the second weft thread (2; 5) is bound in one plane by the tension warp threads SK1 and SK2. In Fig. 5 the tension warp threads SK1 and SK2 of two reed dents located next to each other are shown. Further, the other weft threads of a group are in each case tied in on opposite sides of the plane formed by the second weft threads 2. In this example, the weft threads (1, 4) are located in each case on the pile side, while the weft threads (3, 6) are located on the back of the web. The web further comprises the earlier mentioned identical groups of pile warp threads, with each group in this example consisting of four pile warp threads PK1, PK2, PK3 and PK4. In this example, the pile warp threads PK1 and PK2 form pile naps and therefore determine the color of the pile area with a pile directed to the left. The pile warp threads PK3 and PK4 are respectively tied in in the upper web I and in the lower web II.
[0060] Entirely analogously, a web can be formed with a pile directed to the right. In that case, the third weft thread (3, 6) is in each case tied in on the pile side, whilst the first weft thread (1, 4) is tied in on the back. As a result, the pile direction changes around. Further, as desired, with one or more of the pile warp threads PK1-PK4, pile naps can be formed. Such variants are all understood to fall within the scope of the invention.
[0061] In the web according to Figs. 6a.1 to 6c.2, a web is shown where the color of the pile directed to the right (Fig. 6a.1 and 6a.2) is co-determined by the pile warp thread PK1. Further (in the upper web I), the color of the pile warp thread PK3 will be visible. Finally, also the color of the first weft thread will play a role in the color formation in the pile area in question. In the pile directed to the left (Figs. 6b.1 and 6b.2) it holds again that the color of the pile warp thread PK1 is co-determinative of the color of this pile area. Further, the color of the pile warp thread PK3 and the color of the weft thread (3) are co-determinative of the color. In the upright pile (Figs. 6c.1 and 6c.2) it holds again that the color of the weft thread PK1 is co-determinative of the color formation in the pile area. It further holds that the color of the pile warp thread PK3 is co-determinative.
[0062] If desired, in other pile areas the role of the pile warp thread PK1 can be taken over by one of the pile warp threads PK2 to PK5. In this way, further color variations can be obtained.
[0063] In the web according to Figs. 7.1 and 7.2, only the pile directed to the left is shown. The difference with Figs. 2a.1 and 2a.2, however, is that in this example three pile warp threads PK1, PK2 and PK3 are present. It has been chosen here to have the pile nap formed in each case by the pile warp thread PK1. The pile warp threads PK2 and PK3 are tied in in the web. The color formation of a pile area is therefore determined by the color of the pile warp thread PK1. Further, it holds in the pile directed to the left, that the weft threads (3) play a role in the color formation, whilst in the pile directed to the right the weft thread 1 plays a role in the color formation of the pile. The pile directed to the right will comprise the weave according to Figs. 2b.1 and 2b.2, the difference being that also two additional pile warp threads PK2 and PK3 are tied in, as set out in relation to Figs. 7.1 and 7.2.
[0064] Finally, referring to Figs. 8a.1 to 8b.3, a further variant of the invention is shown. In this variant too, it holds that first groups of weft threads (3, 4, 5) and second groups of weft threads (5, 6, 1) are present. Moreover, there are third groups of weft threads (1, 2, 3) present. In the embodiments discussed hereinbefore, it held each time that the first group of weft threads were located in lying pile areas with a first direction of the pile, whilst the second groups of weft threads are located in lying pile areas with a second direction of the pile, opposite to the first direction. In this example, however, the first and second groups of weft threads are both occurring in pile areas with a particular direction of the pile. This also holds for the third groups of weft threads.
[0065] Thus, for instance, a web can be obtained where, viewed in the direction of the weft threads, in succession the weaves of Fig. 8a.1, 8a.2 and 8a.3 are applied. The weave of Fig. 8a.1 can, for instance, be used in the first reed dent, the weave of Fig. 8a.2 in the second reed dent, and the weave of Fig. 8a.3 in the third reed dent. Thereupon, the pattern repeats itself. The result is that in the pile area with a pile directed to the left, the weave according to Fig. 8a.1 provides that the color of the weft thread (3) is visible. The weave according to Fig. 8a.2 provides that the color of the weft thread (5) is visible, whilst the weave of Fig. 8a.3 provides that the color of the weft thread (1) is visible. In Figs. 8b.1 to 8b.3 the corresponding weaves with a pile directed to the right are shown.
[0066] Obviously, it is also possible that in a pile area with a pile directed to the left only the weave according to Fig. 8a.1 is applied. Also, in that case, in another pile area with a pile directed to the left, only the weave of Fig. 8a.2 can be applied. The result is that in the first-mentioned pile area the color is determined by the weft thread number 3, whilst in the subsequently mentioned pile area the color is determined by the weft thread number 5. Such variants are all understood to fall within the framework of the invention.
[0067] Finally, referring to Fig. 9, an apparatus is discussed for manufacturing the web according to Figs. 1a-1b (and 2a.1-2b.2). To that end, the apparatus comprises a bobbin rack 1 on which the pile warp threads PK are provided. This arrangement of ground beams comprises rolls 4 with tension warp threads SK and rolls 6 with binding warp threads BK. The apparatus further comprises a shaft mechanism 8 for determining the weave of the figure and binding warp threads. The figure and binding warp threads are therefore tied in in the same manner in each pile area. In addition, the apparatus comprises a jacquard device 10 for determining the weave of the pile warp threads PK. The apparatus further comprises a weft/insertion system 12 for beating in the weft threads (1, 2, 3), etc. Further, there is provided a weft selection device 14 by means of which a choice can be made as to which weft thread is beaten in. In this way, weft threads in color A, B, C can be variably beaten in. The eventual web formation occurs at a position which is indicated by reference numeral 16. The warp threads PK, SK and BK are thereby opened gape-fashion and the weft threads are inserted variable in color A, B, C by the weft insertion system 12. A reed 18 beats the weft against the preceding weft. The web thus formed is supplied to a cutting device 20 which is provided with the knife M mentioned earlier. Thus a web according to Figs. 1a and 1b is formed. The weft selection device 14 is synchronized with the jacquard device 10. To that end, the apparatus may be provided with the control unit 22 which controls the jacquard device 10 and the weft selection device 14.
[0068] For manufacturing the web while also using the weaves according to Figs. 1c and 1d, the apparatus according to Fig. 9 can also be utilized, which requires, however, that the tension warp is also laid in by the jacquard device 10 instead of with the shaft mechanism 8.
[0069] In manufacturing the web according to Figs. 3a-3c, the apparatus according to Fig. 9 can also be used. Presently, however, the bobbin rack 1 is provided with two different colors of pile warp threads PK1 and PK2. By means of the jacquard device 10 it is determined in what way the pile warp threads PK1 and PK2 are tied in so as to obtain a weave according to Figs. 3a, 3b or 3c. For manufacturing the weaves according to Figs. 6a.1-6b.2, 7.1 and 7.2, 8a.1-8b.3, again such an apparatus can be used, but now more than two pile warp threads are tied in by means of the jacquard device. For manufacturing the weave according to Figs. 4a and 4c, the bobbin rack 1 is again provided with two kinds of pile warp threads, viz. PK1 and PK2. The shaft mechanism 8 in this case determines only the weave of the binding warp threads BK1. The jacquard device 10 determines both the weave of the pile warp threads PK1 and PK2, and the weave of the tension warp threads SK for obtaining, as desired, the weaves as shown in Figs. 4a, 4b or 4c.
[0070] Also for obtaining the weave according to Fig. 5, the apparatus according to Fig. 9 can be used. The bobbin rack 1 on the apparatus is provided with bobbins for the different pile warp threads PK1, PK2, PK3 and PK4. Because the binding warp threads BK1 and BK2 are tied in in the same way independently of the direction of the pile, these can be tied in by means of the shaft mechanism 8. The pile warp threads PK1, PK2, PK3 and PK4 as well as the tension warp threads SK1 and SK2 are tied in by means of the jacquard mechanism 10 because the weave of these threads with the weft threads is dependent on the direction of the pile.
[0072] Thus, it is possible to beat in additional weft threads E in each of the aforementioned webs. A few examples of that are shown in various drawings. In the example of Fig. 1a, it holds then that m=3, while n=7. In the example of Fig. 4a, accordingly, due to the additional weft threads E, m=3 and n=8. Thus, jacquard shadow velours according to the invention can also be realized according to a 3/7 W-pile through weave, 3/8 W-pile through weave, etc. Also, for instance, in Fig. 1a, the fourth weft thread, as shown in broken lines, can be woven in on the back of the web, while according to Fig. 1b the third weft thread is tied in on the back of the web. Obviously, it is again possible only when a tension warp SK is tied in by means of a jacquard mechanism.
