Abstract: The invention provides a laminating press and a method of laminating an assembly of members having adhesive therebetween. A bed supports the assembly of members to be laminated, and a cover over the bed comprises a flexible diaphragm. Means for evacuating air from between the bed and the diaphragm is provided to urge the diaphragm towards to bed to exert laminating pressure on the assembly. Further means are provided to exert pressure over and above atmospheric pressure on the diaphragm to further urge the diaphragm towards the bed and exert an increased laminating pressure on the assembly to be laminated.
