Abstract
A plurality of reinforced plastic parts are simultaneously molded from separate bundles of resin impregnated strands wound about individual frame sections of a substantially planar frame assembly. A loading station includes a dual-acting elongated carrier engaging the multi-sectioned frame assembly and initially rotatable to wind the bundle of strands thereon. Subsequent reciprocation of the carrier delivers the wound frame assembly to a molding station provided with a plurality of mating pairs of mold sections and having displaceable frame supporting and bundle clamping assemblies for engaging the wound frame assembly and severing opposite ends of the bundles as the mold sections close within the individual frame sections. Upon opening of the mold sections, molded parts and the empty frame assembly are subsequently shuttled from the molding station by a removal station provided with a reciprocating elongated carrier axially aligned with the center line of the molding station and the loading station carrier. Acceleration of the molding cycle may be achieved by pre-heating of the wound bundles intermediate the loading and molding stations.
