ABSTRACT:
A composite lumber product of consolidated comminuted wood and thermosetting resin made by a method which comprises densifying the material into a product-shaped heated metal mold by applying the compressing thrust in a direction parallel to the width dimension of the lumber-like article produced, rather than in the direction parallel the thickness dimension as in conventional hot platen pressing. Densifying in this manner produces much superior orientation of the wood grain along the long axis of the composite lumber product. The timed period elapsed during the densification to dimension now can be, and must be, quite short--of the order of twenty seconds or preferably less--allowing maximum heat transfer into the densified material from the hot metal broad-face (W.times.L) surface to thus minimize the presstime required. Apparatus for carrying out the method is disclosed.
