Abstract
Two rolls are mounted to a frame and rotated about spaced parallel axes by electric motors operating through speed reducers. Each roll has a surface formed of uniformly spaced, circumferential extending triangular grooves and ridges defined between grooves. The ridges of one roll are closely spaced from the grooves of the other roll to define a sinuous nip therebetween. A vibrating conveyor orients wood strands and feeds the strands to the nip with the grain of the strands parallel to the roll ridges and grooves. Wood chips have low strength transverse to the direction of the grain and, thus, when forced to flex by the interdigitating ridges and grooves of the opposed rolls, split into narrower strands.
