ABSTRACT:
In a pultrusion system, a plurality of tape plies made of resin impregnated filaments or fibers are laminated by combining the plies into a longitudinal composite of tapes and pulling the combined tapes through a heated die which compresses and cures the resinous tapes into a unitary laminated structure. The individual tapes are stored by winding them on reels, interleaved with a release tape. A method and apparatus for handling the release tapes are provided, in which such tapes are stripped away from and disposed of at a rate equaling, on the average, the rate at which the resin tapes are fed to the laminating die. An electromechanical resolver is coupled to one of the resin tapes and, as it is pulled from the reel toward the die, the resolver measures its longitudinal rate of travel by issuing a succession of electrical trigger signals, each trigger signal representing a predetermined distance of travel of the resin tape as it is withdrawn from the reel. A plurality of pull rollers are synchronously driven, with respect to the rate of dereeling of the resin tapes, by rotating the pull rollers in successive increments, each increment of rotation being effected in response to one of the successive trigger signals from the resolver and being produced by an air cylinder stroke advancing a continuous loop drive chain coupled to the pull rollers. Each increment of rotation of the pull rollers is selected to pull the release tapes by a distance equaling a predetermined increment of travel of the resin tapes associated with each resolver trigger signal.
