ABSTRACT:
Apparatus for producing reinforced plastic sheets and reinforced plastic sheet laminate structures on a high speed continuous basis and which sheets and laminate structures may have widths ranging from relatively narrow to very wide. The apparatus comprises a means for bringing one or more layers of resin impregnated, fiber-containing, reinforced plastic composite material into contact with each other or into contact with surfaces of one or more endwise abutted relatively flat panels. The apparatus is provided with a pair of continuously rotating belts having a gap there between which receives the laminated sheets. A housing forming a plenum chamber faces the interiorly presented surface of one of the belts and causes a body of pressurized air to be formed between the housing and the interiorly presented surfaces of the belt. Preferably, a similar housing creates a pressurized air body between such similar housing and the other of the belts.
