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.
Claims8
A manufactured wood product comprising:
- a pile of single layers impregnated with a phenolic resin adhesive, each single layer comprising a plurality of sequential sections at a single level in the pile, each sequential section formed from a plurality of wood pieces that are split and disrupted in a lengthwise direction and adhered together in horizontal and vertical directions;
- wherein abutting ends of sequential sections in each single level in the pile do not overlap abutting ends of sequential sections in any adjacent single level in the pile and an adhesive portion is disposed between each of said single layer thereby forming a substantially flat, substantially even surfaced and substantially voidless wood product.
