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.

Deux rouleaux (34, 36) montés sur un bâti (30) sont entraînés en rotation par un moteur électrique autour de deux axes (62) parallèles distants par l'intermédiaire de réducteurs (58). Chacun des rouleaux (34, 36) présente une surface (40, 42) faite de rainures (44) triangulaires et de crêtes séparant les rainures, régulièrement espacées et s'étendant circonférentiellement. Les crêtes (46) de l'un des rouleaux (34, 36) sont proches des rainures (44) de l'autre rouleau (34, 36), de manière à constituer entre les rouleaux une pince sinueuse (32). Un tapis vibrant (23) oriente les copeaux de bois (22) et les convoie vers la pince (32) de manière à ce que le fil des copeaux soit parallèle aux crêtes (46) et aux rainures (44). Les copeaux de bois (22), qui présentent une faible résistance perpendiculairement à la direction du fil, se divisent en copeaux plus étroits lorsqu'ils sont contraints à la flexion par les crêtes (46) et rainures (44) des deux rouleaux opposés.
