    A pair of grippers for shutterless looms, of the type wherein a first gripper (carrying) grasps the weft thread at one side of the loom and carries it to the center of the warp shed, while the second gripper (drawing) receives the weft thread at the center of the warp shed from the carrying gripper, and transports it to the opposite side of the loom, where it releases the same. The weft thread grasping and holding members are mounted on head parts of the grippers disposed on opposite sides of a sliding plane. Along said sliding plane said head parts move side by side, cooperating between them for grasping and releasing the weft thread.

    (54) INVOLVING WEAVING MACHINE
    权利要求:
    Claims (6)
    [1]
    The invention relates to textile manufacture and is intended for use in weaving from fixed weft packages. A shuttleless weaving machine is known that contains a feeder placed on a bat and a receiving gripper, each of which is fixed by a tail part on a flexible rapier connected to the drive and having a clamping element for the weft thread 1 in the head portion. However, when the rapiers come together, collisions of their grippers are possible when one clamping element penetrates each other, as a result of which the weft yarn may be tangled and broken. The aim of the invention is to increase reliability in operation. This is achieved by the fact that the clamping elements are placed on opposite sides of the plane of their mutual slip. The plane of the mutual sliding of the clamping elements is located to the plane of the batan's bay at an angle from 0 to 90 °, while the plane of the rapier tape is perpendicular to or parallel to the plane of the bird. The head part of the pick-up grip has a pair of fonts installed on both sides of the clamping element, and its tail part adjacent to the slip plane has a guide for the weft thread protruding beyond this plane, which is set in such a way that the weft thread in the area between the pins and this the guideway is set at an angle of 25 ° to the direction of the rapier movement. The feed gripper has a slotted lid for accommodating the clamping member, with the studs located in the openings in the flap. Pins can be installed in the cap and located in the grip holes. FIG. 1 is a front view of a weaving machine at the moment of transfer of the weft yarn, when the plane of mutual sliding of the grips is perpendicular to the plane of the reed and the plane of the rapier tape is parallel to it; in fig. 2 - the same, top view; in fig. 3 - plane of the rapier tape, when it is perpendicular to the plane of the thigh, top view; in fig. 4 shows an embodiment of the machine in which the plane of mutual sliding of the grips is parallel to the plane of the reed, and the plane of the tape, which is perpendicular to it at the moment of convergence to transfer the weft yarn, is a top view; in fig. 5 6 and 7 - details of the feed grip. The machine contains a feed grip 1 and a receiving grip 2. The clamping elements 3 and 4 are mounted on the head portions 5 and 6 of the grips, respectively, which are located one on one, the other on the other side of the plane a — the plane of their mutual slip at a meeting to transfer the weft yarn . The plane a can be located to the plane of the reed at an angle from 0 to 90 °, while the plane of the rapier tape can be parallel or perpendicular to it. The grippers 1 and 2 are mounted on flexible rapiers 7 and 8, which are moving in the guides 9. The clamping element 3 of the feeding gripper 1, designed to grip and hold the weft yarn, has a longitudinal elastic plate 10 compressed by a leaf spring 11 and a pair of calipers 12 and 13, located on either side of the plate 10. At the tail end, the grip I has a protrusion 14 extending beyond the plane a, on which the guide 15 for the weft yarn is made. Feed grip 1 consists of a body 16 and a lid 17 superimposed on the body 16 and having a slot 18 for the plate 10 and a spring II. The protrusion 14 and the guide 15 are made on the lid 17. The studs 12 and 13 are mounted on the lid 17. -and, during assembly, fit into the corresponding holes in the housing 16. The pins 12 and 13 can be installed in the housing 16 and enter during assembly into the holes in the lid. The head part 5 of the feed grip 1 has an edge 18 protruding perpendicularly in the end part of the body and intended to protect against the capture of the warp threads. When the rapier begins to move towards each other, the weft thread falls under the plate 10, the curvature 13 and 12, and lies in the guide 15. In this zone, the weft thread is inclined to the direction of the rapier at an angle of up to 25. from the pickup to the receptionist. At the same time, due to the inclined arrangement, the weft thread is not loosened by the frontal action from the receiving gripper. The application of the invention allows to increase the reliability of operation by reducing the contacting surfaces at the time of transfer of the thread, reducing its tension, and create more compact and lightweight gripping devices. Claims of invention. An shuttleless weaving machine containing feed and take-up arms placed on a baton, each of which is fixed by a tail part on a flexible rapier associated with the drive, and has a clamping element for the weft thread in the head part, characterized in that increase reliability in operation, clamping elements are placed from opposite sides of | H from the plane of their mutual slip.
    [2]
    2. The machine according to claim 1, characterized in that the plane of the mutual sliding of the clamping elements is located at an angle to the plane of the bat, at an angle from 0 to 90 °, while the plane of the rapier tape is perpendicular to the plane of the Byrd.
    [3]
    3. The machine tool according to claim 2, characterized in that the plane of the rapier tape is parallel to the plane of the reed.
    [4]
    4. Machine on PP. 1 and 2, characterized in that the head part of the feed grip has a pair of fonts mounted on both sides of the clamping element, and its tail part adjacent to the slip plane has a guide for the weft yarn protruding beyond this plane, such that The weft thread in the area between the teeth and this guide is inclined up to 25 ° to the direction of the rapier movement.
    [5]
    5. A machine according to claim 3, characterized in that the feed jaw has a lid with a slot for accommodating the clamping member, the shafts being located in the holes in the lid.
    [6]
    6. Machine according to claim 3, characterized in that the studs are installed in the cover and are located in the grip holes. Sources of information taken into account in the examination 1. French patent number 1595579, cl. D 03 D, 1970. J
