Abstract: A hot press apparatus in which workpieces are placed between heating plates in a chamber of a machine bed, so that the workpieces are heated and pressed by moving a movable plate toward a stationary plate to form a laminate, wherein the movable plate is held at its peripheral portions by shaft members and is moved toward the stationary plate by a drive means. A center portion pressing member is provided at the center portion of the movable plate to press substantially the enter portions of the heating plates.

Abstract: A structure of a laminate press machine for hoisting up a movable board with lifts located above an upper board is proposed, wherein the movable board (and pressure plates) can be hoisted in a well-balanced parallel position while at the same time obviating the inconveniences which otherwise might be caused in the various parts at the time of hoisting. In a press machine so configured that a movable board is hoisted by lifts located above an upper board to press each workpiece L between pressure plates, guide bars are vertically erected in the neighborhood of the four corners of said movable board and have guide surfaces in a plane where said movable board is not rotated about the center of the flat surface where the lines from the neighborhood of the four corner positions cross each other, the guide surfaces extending from the neighborhood of the four corner positions in the direction along the crossing lines.
