Abstract: A gripper for transporting filling yarn in a projectile (A) across a loom for insertion during weaving is carried by spring arms (B). The gripper includes opposed jaws one of which has a V-shaped inner surface (C) and the other jaw has a W-shaped inner surface (D) receiving an end of filling yarn (Y) when the gripper is closed. The method includes transporting the filling yarn across the loom while engaged by the opposed interengaging inner surfaces of the jaws.
