ABSTRACT:
The procedure is actuated by the apparatus shown in FIG. 3, part B of the mold of which, relatively movably, holds an elastically deformable chamber C which is caused to expand by a fluid under pressure. Into cavity A1 of relatively fixed mold A textile reinforcement D and some liquid resin is placed. If the product to be molded has projecting parts A1, part B is provided with pushers 12 having shaped ends 14, actuated by a pressurized fluid to push forward a part of woven armor D into cavity A4 before causing chamber C to expand. When this condition occurs, the liquid resin is pressed into the structure of reinforcement D and, in solidifying, takes on the shape of cavity A1 of the mold.
