Abstract

The invention relates to the textile industry, a device for producing a shaped thread, and improves its quality by ensuring an even distribution of the shaped effect along its length. A bar for guiding the core threads is placed between the feed pair for feeding the core threads and the feed pair for feeding the surge thread. A two-tooth comb is installed between the hollow spindle carrying the package with an interlocking thread and the feed pair for feeding the suture thread, the distance between the teeth of which corresponds to the length of the annular shoulder in the middle part of the pressure roller of the feed pair for feeding the suture thread. The comb and the rod are located relative to the plane passing through the clamping lines of the supplying pairs of the plane on the side of their pressure rollers and at distances from it which are smaller than the height of the annular shoulder of the pressure roller. 2 yl "

Description

The invention relates to the textile industry and relates to a device for producing shaped yarns that are looped or buccaneed.

The aim of the invention is to improve the quality of the shaped thread by providing a uniform distribution of the shaped effect along its length.

FIG. 1 shows the general scheme of the device; in fig. 2 - the same, side view.

The device contains a feeding pair 1 with a pressure roller 2 for feeding two core threads 3 and a feeding pair 4 placed in the direction of movement of the core threads behind it with a pressure roller 5 having an annular shoulder 6 in the middle part for feeding the suction thread 7. Between the feeding pairs The rod 8 is fixedly mounted to guide the core threads.

The device comprises a hollow spindle 9 with a holder 10 of the supply package with an interlocking thread 11, an outlet pair of rollers 12 and a winding unit (not shown) of the shaped thread 13.

Between the hollow spindle 9 and the feed pair 4 there is a bi-tooth comb 14 for guiding the core filaments, which is the distance between the teeth 15. It corresponds to the length of the annular shoulder 6.

The comb and the rod 8 are located relative to the plane passing through the clamping lines of the supplying pairs of the plane from the side of their pressure rollers and at a distance from it that is smaller than the height of the annular shoulder 6 of the pressure roller 5. The comb is made of glass steel with a width of its teeth equal to 4-6 mm . The bar is made of steel and has a diameter of not more than 2 mm.

Arrange as follows.

The core threads 3 are fed by the feed pair 1, the bar 8 is knocked, passed under the pressure roller 5 of the feed pair 4 from its two ridge sides, encompass both IG comb 1 14 from their opposite structures and enter the torsion zone.

The nonshit 7 is fed by a flange 4 of the pressure roller 5 pressed against the drive cylinder of the supply pair and the drive cylinder of the pair of eyy pair with a speed exceeding. The feed speed of the rod yarns, which provides an excess of this thread to form a shaped effect.

The thread passes through the comb 14 and enters the torsion zone.

 5a, the rod 8 and the comb 4 are displaced with respect to the feed pairs passing through the lines towards their pressure rollers and the comb, the rod threads are raised above these clamping lines of the feed pairs, and the comb teeth deflect the rod threads from the ends of the annular shoulder of the pressure roller of the feed pair supplying the suction filament, which ensures strictly fixed trajectories of movement of the rod filaments in the gap between the driving cylinder of the feed pair 4 and its pressure roller 5, the possibility of the bar filaments being excluded in the mode of this pair 4 and their speed is kept constant.

The twisting of the core yarns 3 by the surge thread 7 and the uniform formation of the shape effect on the rod ends, the fixation of which is accomplished by twisting them with a clamping thread 11 in the hollow spindle 9

The final pair of rollers 12 feeds the shaped nsh to its winding assembly.

The presence of a thread guide bar and a dividing comb in the device, placed at a distance from the plane passing pair through the clamping lines, improves the quality of the shaped thread by clearly separating and fixing the trajectory of movement of the core threads and maintaining the desired speed of movement and ensuring thereby uniform distribution of the shaped effects along the length of the shaped thread.
