Abstract
A method and apparatus are provided for manufacturing a composite wood product from split and disrupted pieces of a raw material such as cedar, willow or bamboo. The composite may be employed as a thick plate of wood, pillar wood, beam wood and the like used for furniture, buildings, and structural objects. The composite is formed by roughly splitting and disrupting a fibrous raw material lengthwise. The roughly split and disrupted material is then finely split and disrupted, and then dried. A single layer is formed by laterally arranging and adhering the finely split and disrupted wood pieces. The single layers are then formed into a pile and heated and pressure tightened.

Apparatus for splitting and disrupting a raw material, comprising:
- a first station and a second station;
- said first station comprising:
- first and second confronting rotary knives, each including a rotary drum with a lateral surface and a plurality of circular blades extending radially from and spaced longitudinally along said rotary drum lateral surface;
- wherein each blade in said first station includes a substantially continuous circular blade end and said confronting rotary knives are arranged such that the blade ends of said first rotary knife are adjacent respectively corresponding blade ends of said second rotary knife and form at most a small gap therebetween;
- said blade ends in said first station are about 10 mm apart longitudinally on said rotary drum and said blades extend about 30 mm from said rotary drum lateral surface;
- said second station comprising:
- first and second confronting rotary knives, each including a rotary drum with a lateral surface and a plurality of circular blades extending radially from and spaced longitudinally along said rotary drum lateral surface;
- wherein each blade in said second station includes a substantially continuous circular blade end and said confronting rotary knives are arranged such that the blade ends of said first rotary knife are adjacent respectively corresponding blade ends of said second rotary knife and form at most a small gap therebetween;
- said blade ends in said second station are about 4 mm apart longitudinally on said rotary drum and Said blades extend about 7.5 mm from said rotary drum lateral surface;
- wherein said first station is adapted to receive raw material with thickness of about 25-30 mm and transform said raw material into a first plurality of elongated members with cross sectional dimensions of about 7.5-10 mm by 25-30 mm, and said second station is adapted to receive said first plurality of elongated members and transform said first plurality of elongated members into a second plurality of elongated members with cross sectional dimensions of about 4 mm by 7.5-10 mm.
