    摘要: A combination heated, vacuum and pressure press is provided for facilitating the transfer of a substance from a workpiece to which it is weakly adhered to a substrate to which it is more permanently adhered by means of a heat-activated thermosetting adhesive. The press consists of a platen having vacuum passages therein with a flexible blanket overlying the platen so that it may be drawn tightly to the platen upon application of the vacuum and a cover in the form of a dome sealingly engaging the platen and forming a chamber thereover, the cover having an internal heating element and the press having means to pressurize the interior of the chamber formed between the platen and the cover so that positive pressure can be exerted on the flexible blanket while the interior of the dome is at the same time heated to assure perfect transfer of a substance from a workpiece to a substrate underneath the blanket.
