ABSTRACT:
There is disclosed a pressing apparatus for fabricating a dense, rigid, durable panel from a molten composite material, such as a composite of wood fibers and thermoplastic. The apparatus features a first platen in spaced and angled relation to a second platen to define a gap between said platens. The gap decreases uniformly from first ends of the platens toward second ends of the platens, and conveyer belts, movably disposed along opposing surfaces of said platens, move molten composite material through the decreasing gap to compress the molten composite material between the platens, while substantially simultaneously the material undergoes first passive and then active cooling into a rigid sheet.
