Abstract
A weft clamp (8) of a gripper head in a shuttleless loom is operated by a finger (10) driven by a coupling rod (13) which in turn is activated by a cam drive (18; 30, 31). The finger is mounted to the upper end of the coupling rod which is guided by a rocker arm (24) that follows the reed or sley motion. The lower end of the coupling rod is directly coupled through a cam follower roller (17) to the cam drive (18; 30, 31), either by one or more springs that assure a continuous engagement of the cam follower roller with the cam or by a bellcrank lever that engages a double cam with two rollers, one at each end of the two bellcrank arms. In both instances only one pivot or journal is needed in the transmission link for the actuating force for operating the clamp operating finger (10) in synchronism with the sley oscillating movement and in synchronism with the gripper movement.
