Abstract:
An apparatus for producing a fiber reinforced thermoplastic material comprising:an impregnation chamber having an entrance end and an exit end, the exit end including an exit die; means for directing continuous filaments along a predetermined advancing path of travel into and through said impregnation chamber, entering through said entrance end and exiting through the exit die; an extruder for providing a supply of molten, thermoplastic polymer; means for directing molten thermoplastic material from said extruder into the impregnation passageway and into intimate contact with the filaments to promote wetting and impregnating of the filaments with the molten thermoplastic polymer; and means for imparting relative rotation by rotating the exit die about the axis of the advancing filaments.
