Abstract

Usage: in the textile and light industries. SUMMARY OF THE INVENTION: a method for producing warp weaves consists of laying the warp threads alternately on two needles, pumping the ear comb from hooks to the backs of the needle needles, shifting the ear combs behind the backs in the needle needles, and pumping it from the backs of the needles to their hooks from the side opposite to the application of warp threads on it. 5 il ...

Description

. The invention relates to the textile and light industries, in particular, to methods for making warp weaves based on stitching and stitching machines.

An object of the invention is to increase productivity. , Figure 1 shows the position in the hallway needles and ears at the time of starting pumping of the ears from the hooks to the backs of the needles; figure 2 is the same, a top view; Fig. 3 shows the position in the quill needles and ears at the end of the laying of warp threads under the hooks of the needles; figure 4 is the same, a top view; Fig. 5 is an example of one of the possible configurations of the trajectory of movement of the ears.

The proposed method involves the movement of the ear 1 with the warp thread 2 emerging from the point. 3 webs 4 and fixed in the old loop along the path 5. The movement of the ear 1 includes pumping from the tip of the needle 6 to its back,

the shift behind the backs of the needles b, 7 and 8 and the pumping from the back to the tip of the needle 8. The trajectory of movement of the ear can also be curve 9. The implementation of this method on the grooming machines does not require complicating the design of the mechanisms of transverse and longitudinal movement of the ear combs (pumping and shear) and is possible with the help of the simplest articulated lever mechanisms, as well as with the help of the articulated lever pumping mechanism and the cam mechanism for shifting the ear comb.

When weaving, in which each of the warp yarns is laid alternately on two needles, for example, the cloth is as follows: after the weaving of the comb 4 has been sewn, sewn with thread 2 of the warp, fixed at point 3 of the old loop formed on the needle 8 , in the hall needles 6, 7 and 8 begin to move up, the eyelet 1 moves along the trajectory 5 (or 9) and reaches this

6 from the side opposite to the one on which the warp thread 2 is applied to the needle 6, at which the tips of the needles 6, 7 and 8 begin to intersect the plane in which the warp threads 2 lie (Fig. 1), and the thread 2 is laid on the haze 6 located in the inter-needle gap formed by needles b and

7 (figure 2). The needle needles continue to rise, and the ears move from the backs of the needle to their hooks until the hooks in the needle needles are above the plane / in which the warp threads lie. Then, the eyelet 1 begins to move from the hook to the back of the needle 6 (the remaining ears move in the same way with respect to the corresponding needles), puts the thread 2 on the shaft of the needle 6 and extends beyond the backs of the needles. The needles begin to move downward and the thread 2 is laid under the hook of the needle b (Figs. 3 and 4). After the exit of the eyelet 1 behind the backs of the needles, it begins to move along the trajectory 5 for a similar loop formation on the needle 8. For one revolution of the main shaft in the stitching machine, the eyelet 1 with the warp thread 2 forms a loop on the needle 6, and the next eyelet forms a loop on the needle 8.

The proposed method provides the development of the basics of the busy | weaves of leotards, cloth, charm on the basics of the hallway or in the hallway-piercing machine.

The technical advantage of the claimed method over the prototype method lies in the fact that it allows to reduce the amplitude of pumping of the ears. This will reduce the inertial load on the ear ruler, the load on the drive of the ear ruler, therefore, increase the reliability in the hall machine and create prerequisites for increasing the speed and productivity of the machine.
