ABSTRACT:
Apparatus for use in the fabrication of laminated products. A laminator includes lower and upper units, the lower unit adapted to receive a workpiece within a recessed interior cavity and the upper portion providing a hood thereover. An elastomeric membrane, which serves as a diaphragm for transmitting forces, is adhesively secured at the periphery of the upper unit. A peripheral rib structure associated with the lower unit is provided to assure air tight sealing of the vacuum chamber wherein lamination takes place. Ports in the upper and lower members are adapted to accept the outputs of air evacuation apparatus for controllably actuating the membrane to apply a compressive force over the surface of the workpiece during the lamination process.
