Abstract

A press and a method for laminating essentially plate-shaped workpieces under the effect of pressure and heat. In the closed state, a lower press half and an upper press half form a vacuum chamber utilizing a peripheral, one-part, or multi-part seals. A flexible membrane divides the vacuum chamber into a product half that can be evacuated that holds at least one workpiece and a pressure half that can be pressurized. The membrane is constructed and arranged so that it presses the workpiece directly or indirectly against a bottom side of the vacuum chamber due to a pressure difference generated in the vacuum chamber due to the evacuation of the product half and/or due to the pressurization of the pressure half. The membrane is mounted on a membrane frame that can be handled separately and that is connected detachably to the upper press half and that can be mounted on the membrane frame or tensioned in the frame from outside of the press. At least one membrane frame with a membrane mounted on the frame is stored as a replacement frame outside of the press in a magazine.
