ABSTRACT:
The method and apparatus for forming composite wood products particularly composite veneer like products which may be intermediate products and laminated to form the final composite product. Strands are fed from a source of supply at a metered rate, entrained in an air stream and carried along a confined path between an entrainment zone and the source of supply. Strands are condensed onto a surface to form a veneer lay-up of at least one layer of strands on the forming surface and this veneer lay-up is carried from the path and deposited onto a collecting surface and later consolidated into a composite product. Entraining air and strands not forming veneer are separated in the supply station, the strands fall onto the supply of strands and energy is added to the separated entraining air and it is returned to the entraining zone.
