Abstract: A membrane press and method of elevating a three-dimensional workpiece are provided. The membrane press includes a work base having a supporting surface for carrying the workpiece. A foil-pressing frame is positioned above the workpiece for heating and applying a laminating foil to the workpiece. A plurality of fluid actuated pedestal assemblies are positioned for movement between a workpiece-loading position and a workpiece-lifting position above the supporting surface of the work base. Fluid passages communicate with the pedestal assemblies, and fluid pressure control means. The control means selectively directs a flow of fluid to the pedestal assemblies in response to the loading of the workpiece onto the supporting surface of the work base.
Abstract: The invention is an improved membrane press, and method of elevating a workpiece above the supporting surface of a work base. The membrane press includes a work base having a supporting surface for carrying the workpiece, and a foil-pressing frame positioned above the workpiece for heating and applying the laminating foil to the workpiece. The improvement in the membrane press includes a plurality of workpiece-lifting pedestals residing substantially beneath the supporting surface of the work base. A piston is located beneath each pedestal, and responds to the placement of the workpiece onto the supporting surface of the work base. The piston imparts an upward force on certain ones of the pedestals residing adjacent to and beneath the workpiece to raise the pedestals and workpiece upwardly above the supporting surface of the work base. The raised pedestals permit the top surface, corners, and peripheral borders of the elevated workpiece to be laminated.
