20100230869	VACUUM PRESS MACHINE AND VACUUM PRESS METHOD - A vacuum press machine includes a platen on which a workpiece is placed, an elastic release sheet provided above the workpiece, a frame arranged above the platen and movable toward and away from the platen. The frame urges the release sheet toward the platen with the workpiece therebetween so that a first space, which is air-tightly closed, is formed between the release sheet and the platen when the frame is moved to contact the platen. A portion of the release sheet covering the workpiece presses the workpiece as the first space is vacuumed. After the pressing, the frame is moved away from the platen, and a release sheet conveying mechanism introduces an unused portion of the release sheet to between the platen and the frame, and discharges the used portion of the release sheet from between the platen and the frame.	09-16-2010
