FIELD: textiles, paper.
SUBSTANCE: method of fabric production lies in the mutual interweaving and twining the chain and forming warp yarns with the chain and twining weft yarns, at that the forming warp yarns are located in thread guides of zigzag shape, mounted with the ability of complex motion. At the first turn of the main shaft of the machine during shedding the forming warp yarns in the form of a loop described in the configuration of the thread guide, are moved to a position between the reed and fell of the fabric. After laying the chain weft the reed moves the chain weft yarn to the beating point, simultaneously to the breast beam the fell of the fabric is moved for while the reed enters between the chain weft yarn and the fell of the fabric the thread guides can be placed with the forming warp yarns without contact with the reed. At the second turn of the main shaft of the machine the forming warp yarns encircle the chain weft yarns and located in the shed in the form of a loop. After the formation of the shed, the twining weft yarn is laid both inside the shed of the chain warp yarns and inside the loop formed by the forming yarns. After laying the twining weft yarn is attached to the edge of the fabric; simultaneously with the movement of the reed to the fell of the fabric the forming warp yarns due to movement of the thread guide encircle the chain weft yarn, go out of the shed and area of movement of the reed. At the same time fell of the fabric is returned to its original position. The reed attaches the chain and twining yarn to the fell of the fabric, and parts of the twining weft yarn in contact with the forming warp yarns encircle the chain weft yarn and pass to the front side of the fabric. When forming the background part of the fabric, the thread guide acts as a harness frame.
EFFECT: invention enables to improve the performance of the knitting loom by increasing the rate of formation of loops and working capacity of the shed.

The invention relates to the weaving production of the textile industry and the way of obtaining fabric weft-Leno weave.
A method of obtaining tissue on the loom (Pat. no 2096543 Russian Federation, the IPC D03D 19/00, D03D 23/00, a method of obtaining a tissue on the loom / Erokhin Û.F., Erokhina T.U.; Applicant and patent holder Erokhin Yuri Filippovich. No 4888602/12; Appl. 07.12.1990; publ. 20.11.1997, bul. №32. - 3 C.: ill.), consisting probirka main threads in healds and in perevalke each of the main threads with several neighbouring main thread by lifting and lowering thread and they move in opposite directions in the plane of the fabric, the connection of each filling thread main thread by interweaving, and the main thread melt in two healds.
However, this method does not allow filling-Leno.
For the prototype accepted way of getting fabric weft-Leno weave, described in the patent (U.S. Pat. no 2228977 Russian Federation, the IPC D03D 13/00. The fabric with interlacing Shilova / Shilov. D.B; applicant and patent holder Shilov Sergey Borisovich, no 2002123403/12, Appl. 30.08.2002, publ. 27.07.2007, bul. №21. - 3 C.: ill.), consists in the capture form filling-Leno is the main thread in the shed special hook with a loop before the last weft thread, laying weft threads in this loop at the next turnover of the main shaft of the machine. Then loop of forming thread straightened and pulled out from the throat. Forming the main thread due to the increased tension moves the plot Leno weft yarn forward before the penultimate weft thread, while Leno thread around the root filling thread, form filling, Leno.
However, in the described way to petleobrazovaniya using a special hook can afford to fail in the fabric pattern because in filling unstable (constantly changing) the warp tension associated with the cyclical operation of the machine.
The technical result of the invention is to increase productivity of the machine by speed loop and health throat.
This technical result is achieved by the method of obtaining tissue consisting in mutual interlacing and perejivanii indigenous and forming of the warp with indigenous and Leno threads duck, according to the invention, forming the warp threads come in yarn feeders zigzag shape, installed with the possibility of swinging and reciprocating movement, for the first circulation of the main shaft of the machine in time samoobrazovaniya forming the warp in the form of a loop is moved to a position between bird and edge of the fabric, thus one part of the loop repeats the form of thread guide, and the other is a straight line segment forming the main thread from the thread guide to the edge of the fabric; after laying indigenous duck, bar moves to the indigenous filling thread to the point of the surf, simultaneously with bird towards grudnia machine and move the edge of the cloth on distance necessary and sufficient that when income Byrd to the extreme point of its motion between indigenous weft thread and edge fabrics could be yarn feeders with forming warp without contact with bird; the second turnover of the main shaft of the machine forming the main thread through the path of the bypass traverse root filling thread and are located in the shed in the form of loops corresponding to the form of the throat, after the formation of a pharynx are laid Leno filling thread inside throat of indigenous main thread, and within a loop formed forming thread, after laying Leno filling thread nailed to the edge of the fabric; simultaneously with the movement of the hips to the edge of the fabric forming the main thread due to the path of the bypass traverse root filling thread, and move Leno filling thread to the edge of the fabric and out of the shed and the zone of displacement Byrd, at the same time, the edge of the fabric return to its original position, bird kills indigenous and Leno thread to the edge fabrics, and areas Leno weft threads in contact with forming the main thread, bypass the root filling thread and go on the front side of the fabric; when forming the background section of the cloth, thread guides performs the function heald-frames, and loom working in the traditional way.
Improving the performance of the machine is achieved thanks to the rigid structure of yarn feeders allows you to work with greater speed through a permanent location-forming thread, inscribed in the configuration of thread guide in the form of a loop, compared with a flexible design hooks in the prototype. Increase efficiency throat is carried out by giving the loop rigidity and matching loops from forming threads with the form throat.
Figure 1 presents the time of formation of the background section of the cloth, where forming the main thread is in the upper branches of the throat; figure 2 - the same, where forming the main thread is in the lower branches of the throat; 3 shows the beginning of formation of a filling-Leno weave, where forming the main thread withdrawn from the zone of formation of tissue; figure 4 shows the second phase of formation of the filling-Leno - time pads Leno duck; figure 5 presents the last phase of formation of the filling-Leno; figure 6 (a) shows a simple filling-Leno is the warp and weft threads obtained declared by the way; figure 6 (b) shows a more hard weft-Leno; 7 demonstrated photo tissue, obtained by the claimed method.
For the practical implementation of the method of forming the warp 1, located on the second beam through the system of guides and compensators (not shown), fill in the yarn feeders 2 zigzag shape, installed with the possibility of swinging and reciprocation. To enable complex movement yarn feeders 2 on the frame of the machine is an additional tool. Variants of additional funds that move yarn feeders 2, and forms of their implementation, may be the same as number and types of looms. For example, for machines STB additional tool is a drive yarn feeders with Cams and kontrkultury associated with leverage and floaters. Additional means are equipped on both sides of the machine. First, generate the background section of the cloth, with indigenous basic 3, pick 4 threads and forming the main thread 1 intertwined as one. This yarn feeders 2 function remise. The provisions of yarn feeders 2 at the moment of laying the indigenous duck 4 is presented in figure 1 and 2. Weft-Leno is formed for two revolutions of the main shaft of the machine. At the first turnover of the main shaft of the machine during samoobrazovaniya of indigenous main thread 3 forming the main thread 1 loop, move into position between bird 5 and edge of the fabric 6, with one part of the loop repeats the form of thread guide 2 and the other is a straight line segment forming the main thread 1 from 2 to traverse the edge of the fabric. After laying indigenous duck 4, reed 5 moves to the indigenous filling thread 4 to the point of the surf (to the extreme point of its motion), simultaneously with bird 5 towards grudnia machine and move the edge of the fabric 6 the distance necessary and sufficient that when income Byrd to the extreme point of its motion between indigenous weft thread 4 and edge of the fabric 6 could be yarn feeders 2 with forming warp 1 no contact with Byrd. This provision is presented in figure 3. Figures 1 and 2 distance from the center of rotation Byrd to the edge of the fabric is marked as L, figure 3 and figure 4 as L1.
L1-L=Delta that where d is necessary travel distance of the edge of the fabric to prevent contact yarn feeders with Byrd.
When the second turnover of the main shaft of the machine during samoobrazovaniya forming the main thread 1 due to the path of thread guide 2 bypass the root filling thread 4 and are located in the shed in the form of loops corresponding to the form throat. After the formation of a pharynx are laid Leno filling thread 7 inside throat of indigenous main thread 3 and inside a loop formed forming threads to 1, this provision is shown in figure 4. After installation Leno filling thread 7 nailed to the edge of the fabric 6. Simultaneously with the motion Byrd 5 to the edge of the fabric forming the main thread 1 due to the path of thread guide 2 bypass the root filling thread 4, move Leno filling thread 7 to the edge of the fabric 6 and out of the shed and the zone of displacement Byrd 5, at the same time, the edge of the fabric 6 return on its original position. Reed 5 kills 4 and radical Leno thread 7 to the edge of the fabric 6. Areas Leno weft yarn 7 in contact with forming the main strands 1, bypass the root filling thread 4 and go on the front side of the fabric. This provision is presented in figure 5.
This filling-Leno tissue is hardly deformable, i.e. it is difficult to move ducks relative basis, even at low linear density of tissue. But if you need a tighter weave, as shown in Fig.6 b), in the implementation of the proposed method should be laid in different mouths of indigenous threads in the same loop of forming two threads Leno weft yarn.
The method of obtaining tissue consisting in mutual interlacing and perejivanii indigenous and forming the main thread with indigenous and Leno threads duck, wherein forming the warp threads come in yarn feeders zigzag shape, installed with the possibility swinging and reciprocating movement, for the first circulation of the main shaft of the machine during samoobrazovaniya forming the warp in the form of a loop is moved to a position between bird and edge of the fabric, thus one part of the loop repeats the form of thread guide, and the other is a straight line segment forming the main thread from the thread guide to the edge of the fabric; after laying the indigenous duck bar moves to the indigenous filling thread to the point of the surf, simultaneously with bird towards grudnia machine and move the edge of the cloth on distance necessary and sufficient so that when the income Byrd to the extreme point of its motion between indigenous weft thread and edge of the fabric could be yarn feeders with forming warp without contact with bird; the second turnover of the main shaft of the machine forming the main thread through the path, bypass traverse root filling thread and are located in the shed in the form of loops corresponding to the form of the throat, after the formation of a pharynx are laid Leno filling thread inside throat of indigenous main thread, and within a loop formed forming thread, after laying Leno filling thread nailed to the edge of the fabric; simultaneously with the movement of the hips to the edge of the fabric forming the main thread through the path of the bypass traverse root filling thread, move Leno filling thread to the edge of the fabric and out of the shed and the zone of displacement Byrd, at the same time the edge of the fabric return to its original position, bird kills indigenous and Leno thread to the edge of the fabric, and areas Leno weft threads in contact with forming the main thread, bypass the root filling thread and go on the front side of the fabric; when forming the background tissue thread guides performs the function heald-frames, and loom working in the traditional way.
