Comminution process to produce wood particles of uniform size and shape with disrupted grain structure from veneer
First Claim
1. A process of comminution of a wood veneer to produce wood particles, wherein the wood veneer is characterized by a grain direction and a maximum thickness (Tv), wherein the comminution process consists essentially of feeding the wood veneer in a direction of travel substantially normal to the grain direction through a counter rotating pair of intermeshing arrays of cutting discs arrayed axially perpendicular to the direction of wood veneer material travel, wherein the cutting discs have a uniform thickness (Td), to produce wood particles characterized by a length dimension (L) substantially equal to the Td and aligned substantially parallel to the grain direction, a width dimension (W) normal to L and aligned cross grain, and a maximum height dimension (H) substantially equal to the Tv and aligned normal to W and L, wherein the L×

Abstract
Comminution process of wood veneer to produce wood particles, by feeding wood veneer in a direction of travel substantially normal to grain through a counter rotating pair of intermeshing arrays of cutting discs arrayed axially perpendicular to the direction of wood veneer travel, wherein the cutting discs have a uniform thickness (Td), to produce wood particles characterized by a length dimension (L) substantially equal to the Td and aligned substantially parallel to grain, a width dimension (W) normal to L and aligned cross grain, and a height dimension (H) aligned normal to W and L, wherein the W×H dimensions define a pair of substantially parallel end surfaces with end checking between crosscut fibers.
