  • Patent number: 5567374
    Abstract: Elongate products are molded in a die from fiber reinforced plastics by drawing a bundle of tows through a bath of resin and between two portions of an open die, which is closed under high pressure, and heated to cure the resin. The die is opened and the product is then partly withdrawn lengthwise, to draw further wetted tows between the die portions, and the die is again closed, clamping the tail end of the already cured product which still projects into the die space, or clamping blocks at its downstream end. Cold clamping blocks also clamp the tows at the die upstream end. The products are subsequently severed externally of the die by cutter wheels.

  • Patent number: 5152945
    Abstract: In the production of a fastener, reinforcing fibers (20) are wetted out in a bath (22) of thermoset resin, drawn together into a wetted cable (23) which is placed in a `U`-shaped die recess of a first die part (24), having parallel inner side walls (25), a second part (29) of the molding die having side walls (30) and a concave die surface then closes the recess by slidably engaging the parallel inner side walls (25), and pressure is applied to the wetted cable without expulsion of wetted fibers. Both die parts (25, 29) have die surfaces which include contours (31) of fastener surfaces, which may be outstanding threads, or annular buttress type projections radiating from the shank .
