Abstract
A weft carrying gripper for a weaving loom comprises a gripper body and a weft yarn holding member carried by the gripper body and oscillable relative to the gripper body about an axis parallel to the direction of movement of the gripper alternately to grip and release a weft yarn between a head on the holding member and the body. The head includes a resilient metal lamina secured to the head only at its rear end and extending forwardly to a free forward end. The lamina between its rear end and its free forward end has a straight portion that terminates forwardly in the free end. The free end curves from the forward end of the straight portion away from the body. The head has a recess behind the straight portion and the free end such that, when the holding member has oscillated toward the body, the straight portion lies flat against the body and the straight portion and the free end are free to flex away from the body under the pressure of a weft yarn inserted between the lamina and the body. When the holding member has been oscillated away from the body, the lamina is spaced from the body but inclined forwardly toward the body, whereby the first portion of the lamina to touch the body upon oscillation of the holding member toward the body is at the juncture of the straight portion and the free end of the lamina.
