ABSTRACT:
A recycled wood product is formed from wood products originally made from first cut wood. The recycled wood product is formed by removing external fittings, if any, projecting from the original, wood product and thereafter chipping the original wood product into platelets which are thereafter assembled in layers, glued together and then pressed together. Any excess formaldehyde in the original wood product is removed by the addition of urea. Machinery to practice the process includes a chipping tool which chips the original product into platelets as the original wood product is advanced against the chipping tool on a movable support structure.
