摘要:
A method and an arrangement for the production of composite work pieces of layers laminated to each other, with at least one layer representing a glass plate. First, at least one composite work piece is laminated in a lamination press under the effects of pressure and heat in order to at least activate the adhesive material used for lamination. Then the composite work piece is removed from the lamination press and transported into a curing station and/or cooling station for curing and/or cooling. A testing device for detecting broken glass in the composite work piece is arranged between the lamination press and the curing station or between the lamination press and the cooling station, which detects potentially present broken glass by testing the inherent stability of the composite work piece.
摘要:
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.

摘要:
An arrangement for printing flat workpieces is provided and includes an application roller which rolls on the workpiece surface 6 to be printed and thereby applies a printed image to the workpiece surface 8, the application roller forming a printing cylinder 5 or a transfer roller 1 cooperating with a printing cylinder 5, a counter-roller 2 which forms in cooperation with the application roller a printing gap 3, through which the workpiece 4 passes during the printing process, and a transport device 7 for feeding the workpiece 4 into and out of the printing gap 3 formed by the application roller and the counter-roller 2. A detector device 8 is present in the direction of transport of the workpiece 4, before the printing gap 3, for detecting the position of a workpiece front end 9 or an image beginning mark, and cooperates with the transport device 7, 11 and/or the printing cylinder 5; wherein the transport of the workpiece 4, prior to reaching the printing gap 3, is accelerated or delayed and/or the angular position of the printing cylinder 5 can be changed by accelerating or delaying its rotational motion in order to bring into agreement the beginning of the printed image with the workpiece front end 9 or a determined relative position thereof.
