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.
