Abstract
A method and apparatus for making a charge used in molding a fiber reinforced part. Continuous strands of fibers are impregnated with resin and then cut into segments of predetermined lengths. The segments are collected so that the resin impregnated fiber segments are piled together to form the charge. In one embodiment, the fibers are collected in a controlled manner to provide preselected fiber orientation for the molded part. Also a cutter mechanism is provided for cutting resin impregnated fiber strands pulled over a first rotating drum.
