Abstract: A press has at least two rigid and generally planar platens each comprised of a rigid plate having a face, formed offset from the face with an array of heating passages, and formed with a separate array of grooves open at the face. A cover plate overlying the face is formed at the grooves with an array of throughgoing holes. A heat-exchange fluid is pumped through the heating passages of the core plate to heat the platen and steam is fed into the grooves and through the holes into a workpiece lying on the cover plate.

Abstract: A platen press, especially a multiplaten press has peripheral seals around the press platens to seal off the pressing gaps containing the wood material mats to be pressed on suction passages formed between the platens and communicating suction ducts at the upper or lower sides of the press, whereby fibers are evolved from the mats and are drawn off through these passages and conduits without significant dilution with ambient air or air serving to cool the platens for destruction by combustion.

Abstract: A laminate-making system has a housing forming a tunnel extending in a transport direction and having a downstream end at an assembly station, a press-plate feeder for conveying a succession of press plates along a path through the tunnel to the assembly station, respective upper and lower supports holding respective upper and lower coils of metallic foil above and below the path at the assembly station, and a core-plate feeder for conveying a succession of core plates to a lay-up station adjacent the assembly station. Respective upper and lower foil feeders pull the foils off the respective coils and apply them to upper and lower faces of the press plates at the assembly station. A gripper beam engages leading ends of the foils and of the press plate in the assembly station for pulling the press plate and the foils from the assembly station into the lay-up station and depositing the press plate and foils atop the core plate therein.
