Abstract: A process and an apparatus are provided for producing multilayers having on each of their two outer sides an outer metal foil and between them at least one additional layer. These foils and/or layer(s) are connected to each other by intermediate layers impregnated with adhesive, and the foils of several multilayers are stacked on top of each other, while a separation layer is inserted between them, and are then simultaneously pressed together. It is essential that the metal foil be placed around the separation layer on its underside, end side and upper side in a U-shape before the separation layer is supplied to the multilayer structure.

Abstract: A loading device for a plate press, composed of two loading supports which can be displaced perpendicular to a conveyance direction. Each loading support has at least one holding device with a conveyor belt which travels in the direction of conveyance. A workpiece to be processed is placed on the upper reach of the conveyor belt and is deposited by the conveyor belt in or on the press. The conveyor belt is moved in such a way that the relative speed of its upper reach in relation to a workpiece being conveyed is equal to zero for all states of movement of the assigned loading supports. As a result, no frictional movement occurs between the conveyor belt and workpieces being carried thereby.
