Abstract:
1. A process for producing veneer strips or chipped wood, comprising: forming a plurality of wood groups, each of said wood groups comprising a plurality of board portions positioned in a stacked manner, with their respective grains parallel to one another and to a given grain direction; arranging a plurality of said wood groups one behind the other in a line extending in a longitudinal direction, with their respective grains parallel to said grain direction, to form a closely packed line of said wood groups, comprising a leading group and a plurality of successive groups; feeding said line in said longitudinal direction, transverse to said grain direction, toward a chipping tool, at an advancement speed, such that said leading group is cut by said chipping tool exerting a cutting force on said leading group; applying a longitudinal compressive force in said longitudinal direction, in a manner such that said force urges said leading group by a successive group immediately succeeding said leading group, wherein said longitudinal compressive force exceeds said cutting force and braking the advancement speed of said leading group such that said leading group acts as an abutment to substantially absorb said longitudinal force.
