ABSTRACT:
A system for accurately and repeatedly pulling a length of plastic fastener tape a predetermined distance. The system comprises an indexing gripper assembly and a stationary gripper assembly, the latter being disposed downstream of the former. The indexing gripper assembly is carried on a carriage that travels back and forth on a linear rail. The rotation of a lead screw is converted into linear displacement of the carriage, the lead screw being driven by a servomotor. While the stationary gripper is open, the indexing gripper grips the fastener tape; then the indexing gripper is advanced a predetermined distance, pulling the fastener tape with it. The stationary gripper is then actuated to grip the fastener tape, following which the indexing gripper is opened and returned to its home position.
