Abstract
A gripper projectile for a loom includes a housing (1) made as a hollow body, a weft yarn clamp (2) which is arranged to fit into the housing and at least one connector element (4) which connects the housing (1) and the weft yarn clamp (2) together. The weft yarn clamp consists of a pair of clamp arms (5) prestressed with springy elasticity and a yoke (6) which connects the pair of clamp arms. An insert body (3) of elastic material is inserted between the clamp arms (5). The insert body (3) exhibits a sawtooth like profiling which is formed at its edge faces in such a way that the individual portions (12) of the profile rest with deformation against the insides of the clamp arms (5). The insert body can also be formed with rows of perforations which further enable its edges to deform against the insides of the clamp arms. The perforations can extend across or be parallel to the length of the clamp arms.
