  • Planetary gripper bar drive with adjustable crank and lever arm lengths
    Patent number: 4984609
    Abstract: A gripper bar drive for weaving machines with a cycloid gearbox implemented with a crank arm (3) and an articulated lever (6), has been configured in such a way, that the effective lengths (LK and LH) of the crank arm (3) and of the articulated lever (6), may be modified. This creates the possibility of modifying the stroke of the gripper bars (9) from one value to another, without having to replace the crank arm (3) and the articulated lever (6). Among other things, the implementation can be effected in such a way, that the fastening devices (10) are provided with an eccentric center (M), and the crank arm (3) and the articulated lever (6) may be provided with openings (13, 16) for the fastening devices (10).
