ABSTRACT:
A fiber placement head is moved by a manipulator wrist with respect to a relatively stationary creel assembly, and a plurality of fiber redirect rollers are employed, each having a mounting base. One roller assembly is mounted to the machine with the creel assembly, and one roller assembly is mounted to the fiber placement head, so that a band of fibers is trained around the first and second redirect rollers under tension, and the redirect rollers are motor-driven to swivel about their bases in accordance with spatial orientations of the placement head, therby maintaining control and preventing fibers from jumping off the rollers.
