Abstract
A system for processing a log or cant including chippers, profiling heads, and saws arranged as a sequence of coupled operations. Scanners and computers determine the log configuration and projected configuration of lumber pieces to be derived. One scanning function is the determination of the wane area configuration in the region of the projected side board edges. This enables a determination of the side board edges including acceptacle wane area and the desired orientation (incline or decline) of the boards relative to the path of conveyance. The profiling heads are adjustable in response to computer calculations to edge the established side boards. Stabilizing is provided and includes guide anvils positioned at the board edges following the edging operation.
