    The invention relates to textile machinery, relates to changing the color of the weft yarns on the shuttleless loom and improves the durability of the device. The mechanism contains a number of thread guides 8 that can be moved from the actuator 25 by means of the pushers 16 between the ready position and the working position of feeding the weft yarn to the weft laying tool. The pushers 16 can be selectively connected to the driver 32, swinging in the rhythm of the weft padding frequency, and can also be locked in the working position for several weft feed cycles. 6 hp f-ly, 7 ill.

    Claims (5)
    [1]
    Claim
    1, A device for selectively feeding the weft yarn to the weaving tool of the shuttleless loom, comprising, by the number of weft yarns replaced, weft pack holders and yarn feeders, each of which is connected to its pusher and installed with the possibility of return movement from the ready position to the weft yarn transfer position to the means weft pads for subsequent weft laying, a drive with a leash mounted with the possibility of rocking movement in rhythm of the frequency of laying a duck, executive fur lowering mechanism with actuating elements connected to the corresponding pushers by means of guiding means for rearranging each of the pushers between the position and its connection by means of a thrust protrusion placed on it and disconnecting from the leash, which is connected with the fact that , with a chain for increasing durability, it has a means of locking the pushers in the working position corresponding to the supply of the weft thread to the weft means, and the guiding means connecting the actuators to the pushers have a stationary On the other hand, the guide levers are installed, the locking means having stops on the pushers transverse to the direction of their movement, and corresponding to the dog stops on the guide levers, and the guide levers are mounted to move between the locking and releasing positions of the pusher.
    [2]
    2; The device according to claim 1, characterized in that the drive leash is mounted with the possibility of moving ^, exceeding the position corresponding to the position of the blocking of the pushers, to facilitate their release.
    [3]
    3. The device according to claims 1 and 2, characterized in that
    1621813 '
    1 b, but the contacting sections of the pushers, the leash and the dogs of the guide levers, at least in the contact zone, are made of wear-resistant material, for example, hard alloy.
    [4]
    4. The device according to claims 1-3, which is different. the fact that the guide lever is connected to the actuator actuator rigidly.
    ;5. The device according to claims 1 to 3, characterized in that the guide lever is connected to the actuating element of the actuator by means of control, which is permanently installed with the possibility. oscillating motion in the rhythm of the frequency of laying the duck control rod (the chag and the contact lever pivotally mounted on it), which includes the contact area for interaction with the current element at the moment of release of the pushers.
    6. The device according to claims 1-5, characterized in that the push rods in the area adjacent to the abutment protrusion mating with the leash have a concave portion, the radius of curvature of which corresponds to the movement zone of the leash.
    [5]
    5 7. The device according to claims 1-6, wherein the connection of the thread guide to the pusher has an elastic transmission.
