    The invention relates to textile production, relates to compensating the tension of weft yarns on micromachine weaving machines and allows the machine to expand its technological capabilities by simultaneously forming loops 1 of several weft yarns 2, fixing these loops and releasing one of them to feed to the micromelt 3. Education the loops are produced by the rod 6, and their locking is done by hooks. The release of one of the loops is done by turning the hook associated with the machine weft changer. 1 3.p.f-ly, 3 ill.

    The invention relates to the textile industry, in particular to micromachine weaving machines, and is intended to compensate for the tension of the weft yarns.
    The purpose of the invention is to expand technological capabilities by simultaneously tensioning all weft yarns and freeing each weft yarn to be laid separately.
    FIG. 1 shows the proposed compensation mechanism, axonometrics;
    In this case, the hooks 11 enter the cavity of the rod 6 and there engage the weft threads 2, preventing them from moving under the influence of the pulling force of the nozzle 18. To push one or another weft thread into the orifice of the machine base with the cam 9 retracted upwards. The hook 11, which corresponds to this thread, rotates on the axial thread under the influence of the weft change device, releases it and allows it to move after the rod 6 under the tension

    weft threads; in fig. 3 shows section A-A in FIG. 2
    The compensation mechanism comprises means for forming loops 1 of weft yarns 2 and means for fixing loops 1 and releasing one of them to feed weft yarn 2 to a microarran 3. Loop forming means have a guiding element for threads 2 element 4 made in the form of plates 5 and transverse to nit m 2 a rod 6 having a U-shaped cross section fixed on the lever 7 and connected by a roller 8 to a cam 9 connected

    The use of the present invention will expand the technological capabilities of the loom due to the simultaneous accumulation of weft threads in the form of loops and then selectively feeding one of them to the microloop.

    I. The mechanism for compensating the tension of the weft threads to the device for changing the weft threads of the weaving machine with a micro-needle, containing means for forming the main shaft of the machine tool. The means of fixing the loops of the weft threads, having the loops 1 and releasing one element of the thread guide for the threads, of which for feeding the weft thread to the micro-ruler 3 has the thread holding element 2 10. The latter has hooks 11, the number of which corresponds to the number of weft strands 2, each of the hooks II by means of ti g 12

    made in the form of plates, and a U-shaped cross-section rod located transversely to the weft yarns and connected by a lever with a cam drive to oscillate in the rhythm of the machine and deflect the threads in one direction and release them in another direction, and weft threads 2 passes through the torch 40 means for fixing the loops of the weft nymose 13 and the eyes 14 and 15, placed respectively on the bars 16 and 17, and tucked into the thread-feeding nozzle 18. Micro-shuttle 3 is provided with a clamp 19 of the weft thread and a rod 20 to open the clamp 19.
    The plates 5 of the yarn guide 4 are located on both sides of the rod 6 (Fig. 2 and 3). Instead of the nozzle 18, another device, such as a mechanical device, can be used as a means of transmitting the weft yarn to the micro-rug 3.
    The compensation mechanism works as follows.
    Under the influence of the cam 9, the rod 6, lowering it, deflects the weft yarns 2, forming loops 1. In this case, 45
