Weft carrying gripper for weaving looms adjustable in respect of the thickness of the weft yarn

摘要

A weft yarn carrying gripper for weaving looms comprises a gripper body (1) having a wide bearing surface (4) for the warp yarns and a narrower tip portion (2) separated from the gripper body (1) by a slit (5) for weft yarn insertion. At least the portion of said warp yarns bearing surface (4) delimiting said slit (5) is formed by an upper movable element (6), fixed to the gripper body (1) by adjustable fixing means (7, 8, 9) and bearing onto a sliding plane provided on the gripper body (1), so as to allow adjusting the width of said slit (5). <IMAGE>
