Abstract (en)

[origin: WO2019082222A1] A gripper assembly for inserting the weft yarn into looms without a shuttle, comprising a bringer gripper and a traction gripper. The bringer gripper comprises a main body (1) with a shaped end adapted to be fixed to a control element, a weft guide profile (2), a rocker arm (3) hinged on a rotation pin (4), a reaction spring (6) and a gripper pin (5) of the rocker lever (3), which is rotating about a vertical axis of the main body (1) of the gripper; the reaction spring (6) keeps the gripper pin (5) on one side and closes it at an opposite side to an inclined plane, so as to obtain an self-tightening condition. The traction gripper, which switches the yarn (7) in the center of the fabric with the bringer gripper, comprises a main body (10) with a shaped end, a central part, which includes a drive lever (12) for the opening or closing of a zone of gripping of the yarn (7), a longitudinally sliding rod (11), which has a slider (14) slidable in a hook-shaped portion 15), and an elastic blade (18) fixed to the slider (14), which opens simultaneously with the slider for releasing the yarn (7).
