Abstract
A weft-carrying gripper for a weaving loom comprises a gripper body and a weft yarn holding member carried by the gripper body. The holding member oscillates relative to the gripper body toward and away from a weft yarn gripping portion of the body, alternately to grip and to release a weft yarn between a head on the holding member and the mentioned portion of the body. This oscillation can be either rectilinear movement of curvilinear movement. A flexible elastic element such as a spring metal lamina is carried by the head and is move toward and away from the yarn gripping portion of the body upon oscillation of the holding member. The elastic element, at the time it engages a weft yarn, bends about an axis transverse to the direction in which the head is moving at the time the elastic element engages the yarn.
