Abstract

Carrying gripper to feed the weft yarn in weaving looms - of the type carried by an alternate-motion strap, which comprises a gripper body (1) and an oscillating lever (2) under the action of spring means (4), so as to grip and hold with one end (5) the weft yarn (T) between the same and a base (6) of said body (1), the opening of said gripper being controlled by a gripper-opening device engaging the other end, characterised in that the base (6) of the gripper body (1) has a recess (13) above which is mounted a yielding lamina (14) with which engages the end (5) of said lever (2) holding the weft yarn (T). Said yielding lamina comprises a slot (15) with which is meant to cooperate a complementary projection (16) of said end (5) of the lever (2) holding the weft yarn. <IMAGE>
