Abstract
An improved positioning and feed system for cants or boards has the capability for skewing and offsetting at a pre-positioning station with respect to the saws of a sawing machine. At a pre-positioning station, at least one visible line is directed to and impinges upon an incoming piece. An operator, through the use linear positioners and a first set of movable pins, pre-positions the individual piece with respect to the reference line, skewing and offsetting it as necessary. Once the orientation is selected, a downstream second set of pins which assume the same position as the first set will be moved upwardly. The first set of pins will be retracted, allowing a conveyor table to convey the piece to the pre-positioned second set of pins. With the piece in its pre-priented position, the conveyor table is then moved vertically downward allowing the piece to lie atop a longitudinal infeed conveyor. Additional pins may be utilized according to the particular type of incoming cant or board.
