ABSTRACT:
The specification discloses an optimizing saw including a scanner unit having devices for measuring both the width and length of boards passing through the station whereby board feet can be calculated. More specifically, the width measuring device includes a reference plane and a reciprocating ram opposite the reference plane which engages a board therebetween to measure board width. The optimizing saw further includes a board conveying apparatus having a multi-speed hydraulic motor drive for smoothly and precisely transporting boards through the optimizing saw. Optimal saw cut locations for each board, control of the width-measuring device, calculation of board feet processed, pinch roll actuation, conveyor acceleration, conveyor deceleration, and status of current production against a predetermined bill of materials are all controlled by a single microprocessor.
