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.
