Abstract: 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.

Abstract: In a weaving loom without shuttles, the weft carrying grippers freely bear on the lower lap of the warp yarns and are guided, at least laterally, by a plurality of very simple and light guides, emerging from the sley and/or from the reed.

Abstract: In a mechanism for controlling the motion of the weft carrying grippers in looms, the inlet movement is the rectilinear reciprocating motion of the small end of the final connecting rod of a linkage operated by the main shaft of the loom, and the outlet movement is the rotary reciprocating motion of a gearwheel controlling the straps for advancement of the grippers. The mechanism comprises a screw and a slider through which said screw passes, one of said elements being moved along a fixed rectilinear path by said connecting rod small end, while the other element is caused to rotate about its own axis, parallel to said path, to cause the rotation of said gearwheel. The mechanism comprises, further, rolling means, carried by said slider and being in engagement with the threading of said screw, to cause the rotation of one of said elements, as a function of the translation of the other element.

Abstract: A drawing gripper for gripping and transporting weft yarns in continuous weft feed looms, which draws the weft thread from the carrying gripper at the center of the shed and transports the same out of the shed, said drawing gripper comprising a fixed member carried by a support connected to the means for moving forward the gripper itself, and a movable member, oscillating in respect of the fixed member about a vertical axis, in a horizontal plane parallel to that containing said fixed member. This latter is provided with a hook end extending in a vertical plane, with the inner upper part of which cooperates the end of the movable member, under the action of return spring means.

Abstract: Weft yarn gripping element for gripping and transporting the weft yarn through the shed in continuous weft feed looms, of the type consisting of an elongated flat body of aerodynamic shape comprising yarn gripping means at its extremity, and which is projected in succession with other multiple companion elements into the shed. In this element the yarn gripping means consist of a hooked blade resiliently urged against a lower extension of the elongated flat body, the weft yarn being inserted into the hook of the blade and clamped between said blade and said lower extension of the body.
