ABSTRACT:
Method and apparatus for sorting timber pieces as the same are transversely conveyed include for each timber piece, pairs of supporting members, each including a hook arm and an adjacent straight arm supported by a respective support member mounted on the conveyor. The straight arm forms a part of an angular arm member which is supported both on the support member to which the hook arm is fixed and to the support member which precedes that support member in the direction of travel of the conveyor. The timber pieces are dropped in accordance with a preset program through the movement of the hook and straight arms relative to each other.
