ABSTRACT:
A platen press for pressing loose wood-based material into structural panels at high temperature while exhausting steam generated in the process through vents distributed across the face of a platen to thereby produce an improved product. The vents are periodically cleaned to remove elements of the panel material that have been deposited into the vents with steam flow or mechanical pressure by pins carried within the platen. The pins are positively extended into respective vents by actuating elements housed within the thickness of the body of the platen.
