ABSTRACT:
A method and apparatus for producing elongated boards of artificial lumber reinforced with elongated reinforcing members providing strength thereto. The boards are constructed of any suitable filler material such as ligneous fibers mixed with thermosetting resin. The mixture of fibers and resin are pulled into a compression chamber by a plurality of elongated belts while the reinforcing strands are fed thereto. The belts are rotated to compress the mixture about the strands while the strands are under tension or undulated. Then the mixture is fed through a curing chamber for curing.
