Abstract: A combination gang saw and edger system cuts both cants and flitches into boards. Cants and flitches are fed singly, lengthwise into the system on an infeed conveyor. On the conveyor, the cant or flitch is scanned to produce a lengthwise cross-sectional profile.

A controller responsive to the optimizer directs the positioning of a first and second set of saws on a pivotably mounted saw arbor to cut either a cant or flitch, respectively. The boards cut from the cant or flitch are fed outfed from the system. The system can cut cants with longitudinal curvature and can cut cants or flitches that are placed at an angle to the length of the infeed conveyor.
