ABSTRACT:
A weft thread inserting gripper for a loom is equipped with a guide element attached to a side wall of the gripper. In order to enable the guide element to properly contact the reed when the gripper moves in the loom shed, the guide element and gripper combination is so constructed that at least the guide element can tilt about a journal axis extending in parallel to the direction of gripper movement. This tilting ability can be achieved by mounting the guide element itself to a gripper side wall for pivoting about the journal axis. The same tilting effect can be achieved by mounting the entire gripper side wall carrying the guide element on such a journal axis. Both possibilities assure an optimal surface contact between the guide element and the respective surface in the loom to provide a quiet and smooth gripper motion.
