Abstract

Two rolls (34, 36) are mounted to a frame (30) and rotated about spaced parallel axes (62) by electric motors (56) operating through speed reducers (58). Each roll (34, 36) has a surface (40, 42) formed of uniformly spaced, circumferential extending triangular grooves (44) and ridges (46) defined between grooves (44). The ridges (46) of one roll (34, 36) are closely spaced from the grooves (44) of the other roll (34, 36) to define a sinuous nip (32) therebetween. A vibrating conveyor (23) orients wood strands (22) and feeds the strands (22) to the nip (32) with the grain of the strands (22) parallel to the roll ridges (46) and grooves (44). Wood strands (22) have low strength transverse to the direction of the grain and, thus, when forced to flex by the interdigitating ridges (46) and grooves (44) of the opposed rolls (34, 36), split into narrower strands.
