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.

The method of claim 1 including reducing the pressure of the material as passes through the first gap. 15. The method of claim 14 wherein the pressure reduction across the first gap is greater than 90%. 16. The method of claim 1 wherein the outlet bore has a length at least 2 times the diameter of the bore. 17. The method of claim 1 including increasing the viscosity of the material after the gas has been added. 18. The method of claim 17 wherein increasing the viscosity includes decreasing the temperature. 19. The method of claim 14 wherein the pressure drop within the material across the first gap is substantially greater than the pressure drop across the second gap. 20. The method of claim 1 wherein the first gap is an annular gap. 21. The method of claim 1 wherein the first gap has a width of less than 0.020 inch. 22. The method of claim 21 wherein the first gap has a width of less than 2.5 times the diameter of the conductor.
