ABSTRACT:
An apparatus for driving a gripper belt in a rapier loom comprises a three-dimensional cam drive (1) for converting a rotational movement into a pivotal movement. The cam drive includes a rotatable cam carrier with a guide surface defining a closed curve (11), the closed curve having a generatrix (E) which is a circular arc. A pivot arm (5) engages the curved surface and pivots about an axis (3) of rotation through the center point of the generatrix. The apparatus is compact and it facilitates the adjustment of the stroke length of the gripper belt.
