ABSTRACT:
A cant or plank is moved forwardly on a conveyor system, where its irregular leading lateral edge is measured by a plurality of fixed scanners. In response to measurement of the cant, conveyor movement is altered for orienting the cant relative to a fixed saw line to be executed by a movable saw. The cant is held or clamped in stationary position while the saw is moved on a carriage relative thereto, resulting in severing of the undesired irregular forward edge. The sawn edge is employed as a reference as the cant is then moved forwardly on a conveyor system, where the measurements obtained from the scanners may be further utilized in cutting the cant into desired widths.
