Abstract: A sawing apparatus comprises a base structure including bed rolls defining a horizontal bed plane for supporting a workpiece, a saw arbor carrying at least one saw for rotation about the central axis of the saw arbor, and a carriage supporting the saw arbor so that its central axis extends horizontally above the bed plane. A drive mechanism selectively raises and lowers the carriage relative to the base structure.

Abstract: A flitch or cant is successively transported by a pair of differentially operated clamps, first to a scanning station, and then to a sawing station where the wane is removed. A series of flitches are processed in this manner such that as the wane edge from a first flitch is sawn, a next flitch in succession is optically scanned. The sawing and scanning is accomplished by means of a combination saw and scanner which moves in a direction longitudinal of the flitch as respective flitches are held in stationary positions at the sawing station and at the scanning station. Between passes of the saw-scanner combination, the sawn flitch is conveyed away and the next flitch in line is conveyed forwardly to the sawing position while being skewed by the clamps in accordance with the characterization generated by the scanner.

Abstract: In an automatic sawmill, logs are first sawn horizontally into pieces that are respectively deposited flat side down on a bed plate and conveyed through multiple, close spaced horizontal bandsaws located above the bed plate. Sawn cants are positioned by clamps to have their waney edges removed by a flying saw after clamp retraction.

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 predetermined saw line to be executed by a movable saw whereby the wane will be removed tangentially thereof. 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.
