ABSTRACT:
A loom gripper band driving device includes apparatus for changing the path of motion of the gripper band. The drive device includes a band driving wheel connected to a gear that engages a gear segment pivotable about a fixed support shaft and that is connected by a coupling rod to a crank arm that pivots about a fixed crankarm supporting shaft. The coupling rod is connected at its opposite ends to the gear segment and the crankarm, respectively, with the connecting points between the coupling rod, gear segment and crankarm being variable to change the path of motion of the gear segment and the gripper drive relative to the crankarm and in particular the crankarm supporting shaft.
