Abstract
A method and apparatus are disclosed for making a reconsolidated or reconstituted wood product from a charge of wood components and binder using steam injection pressing to consolidate and bind the charge into a mat in which the wood components are bound to each other to form the wood product. The charge is compressed into the mat by operation of at least the one pressing member in the form of a heated movable platen. The method and apparatus are characterized by the pressure being applied to the charge or mat from the steam injection pressing being independent of the compressing force applied to the charge or mat by the pressing member. The invention is particularly adapted to form beams of relatively large cross section, such as for example in excess of 30 mm, preferably larger than 40 mm.
