Procedure for forming a pantyhose product with continuous processing motion on knitting machines with two needle beds, knitting machine employing said procedure, and pantyhose products made with said procedure

Description

[0001] This invention concerns a procedure for forming a pantyhose product with continuous processing motion on knitting machines with two needle beds.

[0002] The invention also concerns pantyhose products made according to said procedure and also knitting machines with two needle beds which employ said procedure and are suitable for making said products.

[0003] Procedures for the formation of pantyhose products on knitting machines with two needle beds are already known and are expecially suitable for machines with two cylinders or machines with a cylinder and dial.

[0004] Said procedures envisage the formation of two knitted tubes, one within the other, on the two circular needle beds.

[0005] According to said procedures the part relating to the legs is obtained with independent tubular products.

[0006] In the tract corresponding to the panty portion said tubular products are connected together along at least one lengthwise line and are separated along a lengthwise line located intermediately in relation to said line of connection.

[0007] The inner tube is then withdrawn and turned inside out so as to obtain an open, symmetrical pantyhose product.

[0008] In particular, patent IT 916700 (US 4,011,738) in the name of Solis S.r.l. describes a procedure for knitting machines with two cylinders which envisages the formation of the panty portion with alternate motion of the cylinders. Said procedure enables 360° knitted courses to be formed substantially with the passage of the yarn from one needle bed to the other at every inversion of the motion of the cylinders.

[0009] This leads to the formation of two tubular tracts, one within the other, which are open lengthwise and connected to each other along their lengthwise edges by the tracts of yarn passing from one needle bed to the other during the processing.

[0010] The two leg portions are formed, one within the other, with smooth stitches and purl stitches respectively, the processing being carried out with continuous motion of the cylinders and with an independent feed on the two needle beds.

[0011] Said procedure entails considerable limitations as regards the speed of output owing to the inversion of the motion of the cylinders and to the need to limit the feeds of yarn.

[0012] This procedure also involves a poor appearance owing to the presence of a lengthwise portion without stitches which is formed with straight yarns and which corresponds to the line of the crutch of the panty portion.

[0013] During processing on the machine this line of the crutch corresponds to said lengthwise edges connecting the outer knitted tube to the inner knitted tube.

[0014] Said lengthwise portion without stitches is produced by the yarn passing from one needle bed to the other and has a width substantially the same as the distance between the two opposed cylinders.

[0015] Owing to the constructional requirements of the machine the distance between the two opposed cylinders obviously cannot be lessened and said lengthwise portion without stitches is very evident in the product.

[0016] Moreover, said lengthwise portion without stitches impairs the strength and stability of the panty portion of the product.

[0017] Patent IT 992231 (US 3,975,924), also in the name of Solis S.r.l., describes a procedure for knitting machines with two cylinders which envisages the formation of the panty portion with a continuous rotary motion of the cylinders.

[0018] Said procedure envisages that the yarn passes from the needles of the first cylinder to the needles of the second cylinder at a position distanced at an angle from the position at which the yarn passes from the needles of the second cylinder to the needles of the first cylinder.

[0019] This enables the tubular fabrics formed by the two cylinders to be connected together at least at said two positions, a lengthwise separating cut being made so as to correspond with the space between said two positions.

[0020] Said procedure overcomes the limitations regarding the speed of output imposed by the earlier patent, but the nature of the connection made between the two knitted tubes remains unchanged.

[0021] In fact the problems of appearance and strength are made worse by the fact that said lengthwise portion without stitches lies besides the edges obtained after said lengthwise separating cut, and the quality of the product is rendered wholly unacceptable.

[0022] Certificate of authorship CS 169.533 (UHLIR) visualises a procedure whereby it is necessary to employ a machine working with needles with a double spring so as to obtain the fabric as envisaged in the connecting zone.

[0023] In fact, said connecting zone comprises courses of stitches formed with plain and purl stitches in a varying succession and said stitches can be obtained with the same needle only if the latter has a double spring.

[0024] Furthermore, CS 169.533 provides a body portion which, given the same gauge of cylinders, is made with half the number of needles as are used in the invention we are proposing.

[0025] Instead, our invention visualises stitches which are all of the same kind and the connection between the two fabrics which open out and form the panty portion is made in a different way.

[0026] The solution we are proposing not only enables a body (panty) portion to be obtained which is better to wear but also enables a connection to be made between the two edges which is stable in the long term and acceptable from the point of view of appearance. __

[0027] Certificate of authorship CS 195.758 (JAVOREK) offers a procedure with substantial limitations. Said procedure envisages that the needles of the lower cylinder work offset in relation to those of the upper cylinder and that therefore the panty portion, given the same gauge of cylinders, is obtained with half of the needles used in the procedure of our invention and is therefore less easy to wear.

[0028] Each of the two edges of fabric which are united with loops consists of stitches made with the same yarn, whereas our invention envisages that the stitches of the connecting loops are made with the yarn with which the other edge is processed, thereby ensuring greater stability.

[0029] Besides these substantial differences there is another aspect which makes us doubt the possibility of embodying the procedure of CS 195.758 with an industrial process. If we examine needles such as 11 (Fig. 3) intended to make the connection, we shall see that they do not knit the yarn P1 inasmuch as they do not make stitches with it in correspondence with the point of formation of stitches of the upper cylinder (needle 9) although they do make stitches with the yarn P2 in a position thereafter.

[0030] To obtain this result, it is necessary to raise the needles such as 11 of the lower cylinder above the abutting surface of the sinkers of the upper cylinder by an amount greater than the distance between their hooks and the ends of their latches in their position of maximum opening.

[0031] The needles of the lower cylinder will therefore have to penetrate into appropriate grooves in the opposite cylinder and we cannot see how they can still take the yarn P2 in such a position.

[0032] Patent application IT 9522 A/80 (EP 81830142.6) in the name of the author of the present invention describes a procedure for knitting machines with two cylinders or with a cylinder and dial whereby it is envisaged that the panty portion is formed with continuous motion of the cylinders. This is done by forming the two tubular parts connected along a lengthwise zone, where needles of both the needle beds are actuated during the formation so as to obtain, with one or more feeds, a structure of rib stitches with continuous plain stitches and purl stitches. The produce visualises that a lengthwise separating cut is made.

[0033] Besides allowing a good speed of output, said procedure ensures greater strength and stability in the panty part of the product but does not overcome the problem of appearance which, given the nature of the product, is the most important problem.

[0034] It can be understood from the foregoing that the appearance, strength and stability of the panty portion depend on the zone of mutual connection of the two knitted tubes.

[0035] The lack of strength and stability and, above all, the unsatisfactory appearance are shortcomings common to all the known procedures even though the problems of strength and stability were partly overcome with the processing procedure described in patent application IT 9522 A/80 submitted by the present author.

[0036] However, given the nature of the product, a basic problem of the known procedures continues to be the presence, on at least one side of the line connecting the two tubes, of a lengthwise portion without stitches which has a width substantially the same as the distance between the two opposed cylinders.

[0037] The presence of said lengthwise portion without stitches depends on the nature of the connection made between the two knitted tubes in the known procedures and also on the distance between the two opposed needle cylinders.

[0038] As we said earlier, the distance between the opposed cylinders cannot be lessened owing to constructional requirements.

[0039] The purpose of our invention is to embody a procedure for processing the products which overcomes the aforesaid technical problems and provides a product with an excellent appearance.

[0040] According to the invention a procedure is envisaged for forming a pantyhose product with continuous processing motion on knitting machines with two needle beds and with at least two feeds, one for each needle bed, said procedure envisaging the formation of two knitted tubes, one within the other, on two needle beds, whereby the two tubular fabrics are joined together along a lengthwise connecting zone having a length which corresponds substantially to the panty portion of the product, and a lengthwise separating cut is made substantially at the centre line of said connecting zone, said procedure being characterized by the fact that, so as to form the zone connecting the two knitted tubes with at least one feed, the yarn is knitted by needles selected at substantially regular intervals on one needle bed and also by some needles selected on the opposed needle bed, wherein the needles of the first needle bed which have not been selected pass with their own hooks as the same level as the respective sinkers so as not to take the yarn, the needles selected on said opposed needle bed being aligned with needles of said first needle bed which have not been selected, said selection being performed in such a way that said needles of said second needle bed which are selected in one course are not selected in the next course.

[0041] This invention also concerns a machine with opposed needle beds for making two concentric, tubular fabrics by means of at least two feeds of yarn, one for each needle bed, whereby for the connection of said tubes an arc of needles is employed which has a width corresponding to the connecting zone, together with the use of at least one of the two feeds of yarn, said machine being characterized by the fact that in said connecting zone the needles of the corresponding needle bed are selected in such a way that one needle in every N needles passes with its own hook at the same level as the respective sinkers so as not to take the yarn, and that also some of the needles of the opposed needle bed aligned with said needles oftheJicstJieedie bed passing at the same level as the respective sinkers so as not to take the yarn are set to work and knit the yarn with the stitch of the tubular fabric processed by said needles, of said first needle bed thereby forming a connecting bridge, said selection being performed in such a way that said needles of said opposed needle bed which are selected in our course are not selected in the next course.

[0042] This invention is also embodied with a pantyhose product made with said procedure and with a machine as in the foregoing.

[0043] According to the invention said processing procedure obtains an excellent appearance and very good strength and stability in the panty portion of the product.

[0044] We shall give hereinafter, as a non-restrictive example, the description of a preferential embodiment of the invention with the help of the attached tables, wherein:

Figs. 1, 2 and 3 show the actuation of the needles according to a preferential embodiment of the procedure of the invention;

Figs. 4, 5 and 6 show the connections obtained between the knitted tubes with the selection of needles shown in the first three figures;

Figs. 7 show some possible applications with an enlargement of the interlacing made at one of the points of connection between the two knitted tubes;

Figs. 8, 9 and 10 show diagrammatically cross sections of the panty portion of the product made with the selection of needles given in Figs. 1, 2 and 3 respectively;

Fig. 11 gives diagrammatically a front view of the panty portion of the product.

[0045] It is known that two knitted tubes 53A and 53B, one within the other, are formed so as to embody a pantyhose product 50 and that each knitted tube is processed on a needle bed with at least one feed 56 of yarn 55.

[0046] It is known that a connection between said tubes is made during processing along a tract of the lengthwise development of the two knitted tubes 53A-53B so as to form the body portion, or panty portion, 51 of the product 50, and that a separating cut 62 is also made substantially on the centre line of the connecting zone 52.

[0047] After the processing on the machine the inner tube is withdrawn from the outer one and the product 50 is then turned inside out so as to attain the condition shown in Fig. 11, to which the sections shown in Figs. 8, 9 and 10 also correspond.

[0048] According to said condition of the product 50 the parts 61 of the connecting zone 52 which are nearest to the line of the cut 62 and are like the so-called loose threads at the end of work are inside the panty portion 51 of the product 50.

[0049] According to the invention continuous motion is used to form the panty portion 51 of the product 50 and it is envisaged that needles 54 and 154 of both the needle beds A and B are actuated at the same time in the zone 52 of connection of the two knitted tubes 53A-53B.

[0050] In particular, needles 54 at regular intervals are actuated on one needle bed A and some needles 154 of the opposite needle bed B too are actuated at the same time so as to connect the two knitted tubes 53A-53B together.

[0051] Such a procedure obtains stitches which are all of the same type, and the union of the two fabrics constituting the two knitted tubes 53A-53B which open out and form the panty is obtained with connecting loops between two edges of fabric overlaid on each other.

[0052] Said solution not only enables a more wearable body portion (panty) to be obtained but also enables a long-term stable union to be obtained between the two edges.

[0053] In the present description let us consider the embodiment of the product 50 on a machine with two cylinders, each of which has a feed of yarn that supplies the yarn 55 to one of the two knitted tubes 53A-53B; but the procedure can be applied equally well to a greater number of feeds for each knitted tube or else to a machine with a cylinder and dial.

[0054] According to the invention the connection is obtained by knitting the yarn 55 on both the needle beds A and B.

[0055] Moreover, according to the invention needles 154 which are selected on said opposed needle bed have to be offset in relation to the needles 154 actuated for the previous course and for the next course made with the same feed 56 of yarn 55.

[0056] The purpose of this is that each connection, if it takes place every revolution, will take place on a wale of stitches different from those of the connections made in the previous course of stitches and the next course of stitches.

[0057] This prevents the knitted loops from not being well enough anchored and also improves still further the good-looking appearance of said connecting zone 52 by giving it a more graduated aspect.

[0058] Figs. 1, 2 and 3 show a preferential embodiment of the procedure according to the invention.

[0059] The zone 52 connecting the knitted tubes 53A-53B is embodied in this instance within a sector corresponding substantially to thirty-two positions of needles 54-154 and a lengthwise separating cut is performed so as to correspond with position 16.

[0060] The needles 54 on the needle bed A are actuated with a selection of one yes, the next not, and so on, whereas only given needles 154 are actuated on the opposed needle bed B.

[0061] Figs. 1, 2 and 3 show the needles 154 respectively selected in the connecting zone 52 after N successive revolutions of the cylinders.

[0062] The same kind of selection is repeated in the preferential embodiment of the invention every three revolutions of the cylinders or every three courses of stitches, but according to the invention it is possible to repeat a given selection after a number N of courses of stitches other than three.

[0063] In particular, in Fig. 1 the needles 54 on needle bed A which correspond to positions 1 to 32 are selected alternately one yes, the next no, and so on, whereas on the opposite needle bed B the needles 154 corresponding to positions 10, 16 and 22 are actuated.

[0064] In the next revolution the same needles 54 are selected on needle bed A, but needles 154 corresponding to positions 2, 8, 14 and 18 are selected on the opposite needle bed B.

[0065] Positions such as 10, 16, 22 have to be separated from each other by a number of needles proportioned to the distance between the plane of formation of stitches of the sinkers of the upper cylinder and the plane of formation of stitches of the lower cylinder, in practice it can be seen that a position such as 10, 16, 22 must exist at least every three needles.

[0066] Smaller distances between these positions would lead to the breakage of the yarn during processing.

[0067] In the third revolution shown in Fig. 3 the needles 54 selected on needle bed A are still the same, whereas the needles 154 corresponding to positions 12, 20, 26 and 32 are selected on the opposite needle bed B.

[0068] Said figures bring out the fact that for the connecting zone 52 needles 154 are actuated in differing positions on the opposite needle bed B for each of said revolutions and, in any event, are offset in relation to the needles 154 actuated for the previous and successive revolutions, and that the same selection is repeated every N revolutions of the cylinders, N being three revolutions in our example.

[0069] However, according to the invention, if we keep to the criteria for actuating the needles 54-154 which characterize the procedure in question, it is possible to vary within the procedure claimed as wished the number and position of the needles 54-154 selected for the connecting zone 52.

[0070] Figs. 4, 5 and 6 respectively show the connections made between the two knitted tubes 53A-53B after actuation of needles 54-154 comprised in positions 1 to 32 according to the selection shown in Figs. 1, 2 and 3.

[0071] Thus, the machine with opposed needle beds for making two concentric tubular fabrics 57A-57B by means of at least two fees 56 of yarn, one for each needle bed A-B, is characterized by the fact that the selection of needles on the second needle bed B is changed in the courses thereafter by being moved by x needles, whereby x equals two advantageously.

[0072] Said actuation of needles 54-154 at the zone 52 of connection of the two knitted tubes 53A-53B (each of which is made with its own feed 56 of yarns 55) entails the embodiment of two fabrics 57A-57B with smooth stitches, which are respectively plain and purl.

[0073] Said fabrics 57A-57B comprise connecting bridges 59, each of which also bears a specific reference number in the figures, namely 110, 116, 122, 102, 108, 114, 118, 112, 120, 126 and 132, depending on the position where they have been embodied.

[0074] In our example each of said connecting bridges 59 consists of a loop 60 of one of the two fabrics 57A, said loop being extended and knitted into the other fabric 57B, as shown in Figs. 7 for instance.

[0075] Said Figs. 7 show a front enlargement of some connecting bridges 59 in two fabrics 57A-57B which have by now been opened and turned inside out as in the diagrammatic figures 8, 9 and 10.

[0076] For clarity of illustration three possible connecting bridges 59 which have been made between said two tubular fabrics 57A-57B are shown. Said figures show the flexibility of the procedure and the possible variants inasmuch as the selection of the needles can be inverted from one needle bed to the other and moved by one or more wales and repeated after at least one course in which the successive stitch is a smooth stitch, and so on.

[0077] Thus, Fig. 7a shows the case wherein the connecting bridges 59 are made in one revolution but not in the next revolution, and so on, thus ensuring proper fastening of the loops.

[0078] It can also be seen in Fig. 7a how the substitutive fastening of the loop missing at the beginning and also the integrating fastening of the auxiliary anchorage loop are made.

[0079] Fig. 7b shows the example of connecting bridges 59 located in each line; in this case the bridges have to be offset by one wale so as to have a proper, stable anchorage of the loops.

[0080] Fig. 7c instead shows the case of inverted bridges which start now from the fabric 57A and are knitted into 57B and then start now from 57B and are knitted into 57A.

[0081] These examples show precisely the great variability of solutions which can be obtained and therefore of aesthetic effects which can be sought.

[0082] Fig. 11 gives a diagrammatical front view of the panty portion 51 of a product 50 made with the procedure of the invention; in said product the fabrics 57A-57B of the panty portion 51 are fully open and stretched out. The exceptionally good-looking appearance of the connecting zone like a slide fastener can be seen clearly.

[0083] The edges of saidd zone can be distinct or graduated and said zone can also comprise one or more layers of connecting bridges 59.

[0084] Said figures 8, 9 and 10 show cross sections of the panty portion 51 of the product turned inside out and opened; said sections correspond respectively to courses of stitches of the product which are made in the connecting zone with the selection of needles as shown in Figs. 1, 2 and 3.

[0085] Said cross sections make evident the fact that said connecting bridges 59 made between the two knitted tubes 57A-57B vary cyclically in position and number along the connecting zone 52 of the two knitted tubes.

[0086] Besides eliminating the presence of the aforesaid shortcoming which appears at the side of the connecting zone of the panty portion in products made with procedures of the prior art using continuous motion, said criteria of actuation of the needles entail the formation of a connecting zone 52 having an increased thickness and consistency and the further improvement of the appearance of the part connecting the two knitted tubes 57A-57B that constitute the product 50.

[0087] The selection of needles described for making the connecting zone 52 with a given feed 56 linked substantially to one needle bed and thus to the relative knitted tube 57A can equally well be repeated, inverted on the needle beds, with a possible offsetting also for the feed 56 which supplies the yarn 55 to the other knitted tube 57B.

[0088] According to one variant of the invention the connecting courses comprising the connecting bridges 59 are spaced apart from each other, that is to say, they are not consecutive courses.

[0089] According to another variant the connecting courses comprising the connecting bridges 59 are separated from each other by one or more connecting courses forming one single ribbed fabric in the connecting zone 52, said fabric being made by cooperation between the needles of both needle beds A-B in the connecting zone 52.

[0090] According to a further variant a connecting tract formed of one single ribbed fabric obtained by cooperation between the needles of both the needle beds A-B in the connecting zone 52 is comprised in the connecting zone 52 at every two connecting tracts obtained with a number of courses comprising connecting bridges 59, whether separated or not by courses of rib stitches.

[0091] We have described here a preferential embodiment of the invention, but many variants are possible for a peson skilled in this field; for instance, it is possible to change the number of needles 54-154 which take part in forming the connecting zone 52; it is possible to change the cycle of revolutions of the cylinders after which a given selection of needles 54-154 is repeated; the needles 54 of needle bed A can be selected at wider intervals than the 1:1 selection, or else all the needles 54 of needle bed A can be selected except those located in positions corresponding to the needles 154 selected in the opposite needle bed B; it is possible to make the connecting bridges by forming more than one stitch on the opposite needle bed B; it is possible to perform special interlacings of stitches or to suspend the actuation of the needles 54-154 in the lengthwise portions of the connecting zone 52 immediately next to the cutting line; it is possible to apply the procedure to a greater number of feeds for each knitted tube 53, all the foregoing being possible without departing thereby from the scope of this invention, as defined by the appended claims.
