Abstract: The board edger has a longitudinal horizontal board path therein and first and second saw boxes disposed in a tandem mode adjacent the board path. Each saw box has a pair of saw blades mounted therein. The saw blades have a cutting direction that is aligned generally along the longitudinal board path. A controller is provided for coordinately moving the pair of saw blades in the first saw box into the board path for edging a first wood board and the pair of saw blades in the second saw box out of the board path for pre-positioning in view of edging a second wood board. One saw box is used for edging odd wood boards and the other saw box is used for edging even wood boards.

Abstract: A board edger is taught that includes an infeed conveyor, a scanner for scanning a board to be edged as it passes on the infeed conveyor to determine orientation and dimension and a saw. The saw includes a reference plane for supporting a board to be edged, a first saw box disposed adjacent the reference plane and having at least two blades controllable for width, longitudinal angle and depth, a second saw box disposed adjacent the reference plane and having at least two blades controllable for width, longitudinal angle and depth, and a saw controller coupled to the scanner for receiving signals from the scanner and coupled to the first and second saw boxes for setting the first saw box for cutting and controlling the cutting by the second saw box. Advantageously, while one saw box is cutting a board the other saw box is being set up by the saw controller to cut the next board thereby decreasing the spacing required between boards. This increases the throughout of the board edger.
