  • Patent number: 5147653
    Abstract: A fiber placement control apparatus for selectively directing a stream of fiber onto a stationary preform screen, including a rigid, straight fiber delivery tube communicating from a conventional chopper/blower assembly. A first set of four circumferentially equally spaced nozzles adjacent the exit end of the tube directs a binder into the stream of fibers, and a second set of four circumferentially equally spaced nozzles positioned downstream of the first set directs air onto the stream. By selectively operating any three of the air nozzles, the direction of the stream toward the preform screen is controlled. A conventional multidirectional gantry head may serve to move the rigid delivery tube vertically, left and right, and relative to the screen.
