Technical field
[0001] The invention relates to a method of laid fabrics production during which are between
the warp threads strands inserted wefts of required mutual distance, after which is
applied an adhesive on the fabric and the fabric is dried.
[0002] The invention also relates to a device for laid fabrics production comprising means
for warp threads placing and means for warp threads guiding through the working path
to draw-off mechanism and next to adhesive applying mechanism and to a drying mechanism.
Background art
[0003] Laid fabrics, for instance "laid scrim" type are fabrics of basically crosshatched
arrangement, where particular warp threads have mutual distances and also particular
weft threads have mutual distances. These fabrics are used for miscellaneous reasons
according to the character of threads or fibres used for their production, for instance
while using finer threads or fibres it is possible to use these fabrics as an envelope
reinforcement, while using thicker (more rugged) threads or fibers it is possible
for these fabrics to use for instance as in industrial purposes etc. The fabrics are
impregnated by an adhesive, which after setting provides cohesive strength in determined
geometrical arrangement, similarly to for instance in leno weaves in leno fabrics.
A method of and a device for laid fabric production according to the preamble of claims
1 and 5 is known from
GB-A-985 476.
[0004] There is well known a method of laid fabrics production of "laid scrim" type, during
which are the warp threads separated using appropriate means, for instance warp brushes,
into appropriate mutual distance and they are led to appropriate device producing
space between warp threads for weft insertion. Between separated warp threads is by
mechanical means inserted a weft or a group of wefts. Basically immediately after
contacting the warp threads from both sides onto the weft or wefts is applied the
adhesive and occurs weft fixation in determined position. Adhesive drying follows.
[0005] The disadvantage of the background art is mechanical complexity of the device for
laid fabrics production, in particular of the part providing weft insertion between
the warp threads. Another disadvantage of the background art is a limited manufacturing
productivity of laid fabrics.
[0006] The goal of the invention intends to eliminate or at least to minimize the drawbacks
of the art.
Principle of the invention
[0007] The goal of the invention has been reached by a method of laid fabric production,
whose principle consists in that warp threads strands are supplied between a pair
of tension rollers, between which they are merged again, while in the point before
merging the warp threads strands between the tension rollers are between the warp
threads inserted wefts by means of which is produced a laid fabric semi product with
wefts between warp threads which is by wrapping around a part of tension roller circumference
delivered to a draw-off device for next manufacturing operations of an adhesive application
and drying.
[0008] This way it is possible to simplify the manufacturing process while retaining or
improving the performance.
[0009] For improving inserting the wefts to a designated place between the warp threads
strands is advantageous if on the weft is during and/or after weft insertion between
the warp threads strands acted by a stream of an auxiliary medium in the cross direction
to the weft length improving positioning the wefts between the warp threads.
[0010] To reach advantageous parameters of weft insertion, in particular high speed, reliability
and stability of insertion parameters is advantageous weft insertion by means of air
which does not need additional fabric alterations before adhesive application as for
instance drying and it is an inexpensive and available medium.
[0011] For next performance increase of the entire method, because insertion by means of
medium can today attain the highest speed around 80 m/min, it is advantageous if the
warp threads are before the wefts insertion separated into
m strands, where m > 2, while these strands then merge in sequence between
n pairs of tension rollers, where n = m - 1 and in each point before warp threads strands
merging between the tension rollers are between warp threads inserted wefts, while
in each point before strands merging is between warp threads inserted each i·(n+first)
weft, where i is a sequence number of a weft series inserted on all insertion devices
directly one after another, while the fabric is by means of alternating wrapping around
a part of tension rollers tensioned and lead towards the draw-off device for next
processing.
[0012] The principle of device for laid fabrics production consists in that the means for
guiding the warp threads through the working path comprise at least one pair of tension
rollers, between which are separately supplied always two warp threads strands, while
in the warp threads movement direction is a weft insertion device assigned to an area
in front of the entry of warp threads between each pair of tension rollers and behind
each pair of tension rollers is situated a laid fabric semi product tension device
on a part of circumference of one of a pair of tension rollers, while behind the last
pair of tension rollers is situated a draw-off device of laid fabric semi product
for next processing.
[0013] Such device is simple and enables basically modular arrangement of a higher amount
of insertion points and this way also increasing the productivity of laid fabrics
production.
[0014] According to one preferred embodiment is the laid fabrics tension device on a part
of the circumference of one of a pair of tension rollers formed by the first tension
roller from the following pair of tension rollers or it is formed by a draw-off roller
of the laid fabrics tension device, while the working path of the laid fabrics semi
product is established continuously crossing in an alternating direction from one
tension roller to another and next to the draw-off roller of the draw-off device,
which simplifies the device construction because such way the tension rollers fulfil
more tasks at the same time without any problems.
[0015] In terms of controlling and simplicity it is preferred if the weft insertion device
is formed by an air insertion device with an air insertion jet.
[0016] For improving the weft insertion onto an appropriate point it is preferred if the
weft insertion device comprises an auxiliary insertion device in a cross direction
to the weft length.
[0017] In terms of ergonomic design is the device advantageous if the tension rollers pairs
and weft insertion devices assigned to them are situated above each other.

Specific description
[0019] Method of laid fabrics production consists in that the warp threads are separated
into strands which are separately supplied between a pair of tension rollers, between
which they are combined again and they are further delivered combined by means of
wrapping around a part of the circumference of one of the tension rollers for further
processing, while in the point before combining both strands between the tension rollers
are between the warp threads inserted wefts by acting of insertion medium (water,
air) so between the tension rollers enters a fabric with wefts inserted between warp
threads and by means of wrapping around a part of circumference of one of the rollers
are the wefts kept in a desired position between weft threads till setting by an adhesive.
Wefts insertion between warp threads strands before entering between the tension rollers
can be supported by use of an auxiliary medium acting basically crosswise to the wefts
movement direction or diagonally in the wefts movement direction and improving positioning
the wefts between the warp threads, e.g. similarly as well known auxiliary blow jets
in weaving machines. In the Fig. 1 is shown a schematic embodiment of device for carrying
out the method of wefts insertion between warp threads during laid fabrics production,
which consists of a pair of distant separating rollers
1, across which is led always one warp threads strand
a, b. Both warp threads strands
a, b are led between tension rollers
2, which rotate in direction of arrows
x, y. In the area before entering the warp threads between the tension rollers
2 is situated a weft insertion device by acting of insertion medium, for instance water
or air. Weft insertion device consists of an insertion jet
6 directed to a corresponding direction between warp threads strands in the direction
of tension rollers
2 lengths. The insertion device can, as the case may be, comprise also an auxiliary
insertion device
60 for weft insertion improvement between warp threads entering between tension rollers
2. The insertion device inserts the wefts between the warp threads in designated intervals
at defined tension rollers rotation that is at defined warp threads motion, by means
of which is manufactured a laid fabrics semiproduct, which from the area between tension
rollers
2 is under tension from wrapping around a part of surface of a draw-off roller
4 delivered over a surface of one of tension rollers
2 to the draw-off roller
4, after which follows adhesive applying and drying. By means of keeping the tensioned
fabric semiproduct on the surface of one of tension rollers
2 and on the surface of the draw-off roller
4 is reached a stable position of wefts between the warp threads till setting by an
adhesive.
[0020] In terms of reaching an appropriate manufacturing productivity of laid fabric with
wefts insertion by means of a driving medium with maximum attainable weft insertion
speed around 80 m/min, it is advantageous to use the above mentioned method in the
following modification and in the following technical arrangement.
[0021] During mentioned modification of laid fabric production method are the warp threads
in an appropriate manner positioned on a not represented bearing device, for instance
on an appropriate warp beam. Warp threads are by means of appropriate not represented
means, for instance warp combs, separated from each other at desired distance. Consequently
the warp threads, for instance by means of represented system of separating rollers
1 in regular sequences to at least three strands, i.e.
m strands, where
m > 2, from which each comprises a corresponding part of warp threads. Separating the
warp threads into regular sequences means that e.g. in separating into three strands
is the first warp thread led in the first strand over the first separating roller,
second warp thread is being led in the second strand over the second separating roller,
the third warp thread is being led in the third strand, the fourth warp thread is
being led again in the first strand, the fifth warp thread is being led again in the
second strand, the sixth warp thread is being led again in the third strand etc. In
the Fig. 1a to 1c is described separation of warp threads into six strands
a, b, c, d, e, f, while the first warp thread is being led in the first strand
a, the second warp thread is being led in the second strand
b, the third warp thread is being led in the third strand
c, the fourth warp thread is being led in the fourth strand
d, the fifth warp thread is being led in the fifth strand
e, the sixth warp thread is being led in the sixth strand
f, the seventh warp thread is being led again in the first strand
a, the eighth warp thread is being led again in the second strand
b, the ninth warp thread is being led again in the third strand
c, the tenth warp thread is being led again in the fourth strand
d, the eleventh warp thread is being led again in the strand
e, the twelfth warp thread is being led again in the sixth strand
f, etc., by means of which are all warp threads separated into the desired number of
strands.
[0022] From the warp threads strands is by means of described tension rollers
2, either by cascade merging of strands as shown in the drawings or by another appropriate
method, next examples will follow, form weft insertion points
3 before the warp threads enter between the tension rollers
2, while to every weft insertion point
3 is assigned one insertion device working on a principle of insertion by means of
an appropriate medium, for instance water or air. While the number of insertion devices
is one less than the number of warp threads strands. Behind the insertion device system
is a draw-off mechanism, which for instance by means of draw-off rollers
4 provides draw-off of produced fabric to next processing, e.g. to immediate applying
an adhesive and following drying etc. The warp threads are during production of laid
fabrics semiproduct maintained under tension, while they are kept in contact with
rotating tension rollers
2, by means of which are the wefts up to fixation by adhesive reliably kept in the appropriate
position on the fabric semi product. The warp threads subsequently wrap around particular
tension rollers
2 as the particular warp threads strands merge into the final laid fabrics configuration.
[0023] In the shown example of embodiment the warp threads strands for the purpose of formation
of weft insertion points
3 merge in a cascade manner, which means that the strand
a together with the strand
f before entering the first pair of tension rollers
21 form the first weft insertion point
31, the merged strands
a +
f together with the strand
e before entering between the second pair of tension rollers
22 form the second weft insertion point
32, the merged strands
a +
f +
e together with the strand
d before entering between the third pair of tension rollers
23 form the third weft insertion point
33, the merged strands
a +
f +
e +
d together with the strand
c before entering between the fourth pair of tension rollers
24 form the fourth weft insertion point
34 and the merged strands
a +
f +
e +
d + c together with the strand
b before entering between the fifth pair of tension rollers
25 form the fifth weft insertion point
35, behind which comes out the formed laid fabric semi product into the draw-off mechanism.
During this merging of warp thread strands are the warp threads practically constantly
under tension and they are on the surface of the tension rollers so the wefts are
firmly held up to fixing by the adhesive.
[0024] In the not represented example of embodiment the warp threads strands for the purpose
of formation of weft insertion points
3 merge in sequence, i.e. for instance the strand
a together with the strand
f before entering the first pair of tension rollers form the first weft insertion point,
the strand
e together with the strand
d before entering between the second pair of tension rollers form the second weft insertion
point, the strand
c together with the strand
b before entering between the third pair of tension rollers form the third weft insertion
point, the merged strands
a +
f together with the merged strands
e +
d before entering between the fourth pair of tension rollers
24 form the fourth weft insertion point and the merged strands
a +
f +
e +
d together with the merged strands
c +
b before entering between the fifth pair of tension rollers form the fifth weft insertion
point, behind which comes out the formed laid fabric semiproduct into the draw-off
mechanism.
[0025] In another not represented example of embodiment the warp threads strands for the
purpose of formation of weft insertion points
3 merge in another appropriate manner. The specific process of merging particular strands
and a formation of particular weft insertion points in principle depends only on specific
arrangement of the device for laid fabric production.
[0026] In the shown example of embodiment are the tension rollers
2 arranged in pairs
21 to
25 above each other to cascade and also the insertion devices are arranged above each
other to cascade. In the not represented example of embodiment are the tension rollers
2 and insertion devices arranged in another appropriate manner corresponding to the
manner of dividing and merging particular strands of warp threads.
[0027] The insertion device of each weft insertion point
3 is advantageously formed by an air insertion device, which in Fig. 1 consists of
shown air insertion jet directed to the appropriate weft insertion point
3 in the direction of length of tension rollers
2. The insertion device can further consist of auxiliary insertion device
60 for improving weft insertion into the weft insertion point
3 between the warp threads wrapped around the particular pair of tension rollers
2 in the cross direction to the weft insertion direction. The auxiliary insertion device
can be formed for instance by an appropriate longitudinal air jet directed by its
longitudinal outlet to the weft insertion point
3 between the appropriate pair of tension rollers
2. The auxiliary insertion device
60 can also be formed by an appropriate series of auxiliary air blow jets in analogy
to weaving machines. The auxiliary insertion device
60 can also be formed by another appropriate device.
[0028] The insertion devices are coupled with a not represented weft insertion control device,
which synchronize the action of particular insertion devices according to the demands
on produced fabric, for instance also on the basis of operation speed of the entire
mechanism, for instance according to the tension rollers
2 revolutions. The weft insertion control device is preferably coupled with a control
device of the entire machine for laid fabrics production.
[0029] At least some of the tension rollers
2 and at least one from the draw-off rollers
4 are coupled with appropriate drive, for instance electromotor, which can be also
central with an appropriate timing gear.
[0030] The device works so that the warp threads are led in their paths and they are separated
into particular strands, which are subsequently being led over corresponding pairs
of tension rollers
2 on which the warp threads strands merge in sequence and further lead over draw-off
mechanism to the next processing of the laid fabrics semiproduct, in particular to
adhesive application, drying, winding on a beam etc.
[0031] After turning the driving mechanism on the corresponding device parts start to move
(rotate), by means of which the warp starts to move. Subsequently to the warp movement
the insertion devices start weft insertion on weft insertion points
3, while the wefts are in particular weft insertion points
3 consequently by corresponding pair of tension rollers
2 clenched between warp threads of appropriate warp threads strand or between warp
threads of merged strands of warp threads (in dependence on manner of dividing and
merging of the warp threads). During formation of fabric does not occur a shed formation
known at weaving machines but warp threads and wefts are in each weft insertion point
3 overlaid or if you like the wefts are inserted between the warp threads and their
mutual position is being held due to tension rollers and maintaining the warp threads
under tension on tension rollers because the warp threads bear on both sides onto
crosswise passing wefts and the wefts are then being held on their position till application
of adhesive onto the fabric. The activity of particular insertion devices is synchronized
so that in the area of draw-off mechanism the wefts are regularly positioned along
the fabric. Each insertion device has the same interval between insertion of particular
wefts, while these intervals are in particular insertion devices phase shifted so
each insertion device places into the fabric "only" each (is n + first) weft, where
i is a sequence number of insertion on particular weft insertion point,
n is a number of pairs of tension rollers = number of weft insertion points = number
of insertion devices.
[0032] The sequence of sequential positioning of particular wefts between warp threads for
embodiment according to Fig. 1a is such that the first insertion device
51 inserts the first weft
511 between the strands
a and
f, which form the first weft insertion point
31. The first weft
511 runs clenched between warp threads
a and
f along circumference of one of the first pair
21 of tension rollers
2 to the second weft insertion point
32 formed by already merged strands
a +
f and newly added strand
e. In determined distance of the first weft
511 behind the second weft insertion point
32 (according to desired distance between particular wefts in produced fabric) the second
insertion device
52 performs insertion of the second weft
522 between already merged strands
a +
f and newly added strand
e. The first weft
511 and the second weft
522 already clenched between strands
a, f and
e travel along circumference of one of the second pair
22 of tension rollers
2 to the third weft insertion point
33 formed by already merged strands
a +
f +
e and newly added strand
d, while in particular point of the second weft
522 behind the third weft insertion point
33 (according to desired distance between particular wefts in manufactured fabric) performs
the third insertion device
53 insertion of the third weft
533 between already merged strands
a +
f +
e and newly added strand
d. First, second and third weft
511, 522, 533 clenched between already merged strands
a +
f +
e +
d travel along circumference of one of the third pair
23 of tension rollers
2 to the fourth weft insertion point
34 formed by already merged strands
a +
f +
e +
d and newly added strand
c, while in the designated point of the third weft
533 behind the fourth weft insertion point
34 (according to desired distance between particular wefts in produced fabric) performs
the fourth insertion device
54 insertion of the fourth weft
544 between already merged strands
a +
f +
e +
d and newly added strand
c. First, second, third and fourth weft
511, 522, 533, 544 clenched between already merged strands
a + f + e + d + c travel along circumference of one of the fourth pair
24 of tension rollers
2 to the fifth weft insertion point
35 formed by already merged strands
a + f + e + d + c and newly added strand
b, while in the designated point of the fourth weft behind the fifth weft insertion
point
35 (according to desired distance between particular wefts in produced fabric) performs
the fifth insertion device
55 insertion of the fifth weft
555 between already merged strands
a + f + e + d + c and newly added strand
b. However, still before insertion of the second weft
522 the first insertion device
51 inserts into the first weft insertion point
31 the sixth weft, which is the new first weft
511 from the new series of wefts
511 to
555 inserted in sequence by particular insertion devices
51 to
55. This way the first insertion device
51 performs insertion with ordinal number 2, i.e. i = 2. The distance in fabric between
the first weft
511 and the sixth weft (following first weft
511) is such that between these two first wefts
511 inserted by means of identical insertion device are in the final fabric positioned
second, third, fourth and fifth weft of appropriate series of wefts
511 to
555 of appropriate ordinal number
i insertion namely in each cycle repetition of insertion of wefts
511 to
555 on particular weft insertion points
51 to
55.
