Abstract
A shape sawing system for sawing lumber pieces from a curved cant. The cant is scanned by scanners and the scan data is input to a computer. The computer determines a curved path for the saw to follow in sawing the cant into lumber pieces. The saw is laterally and pivotally adjustable to follow the determined path established by the computer. The saw is a plurality of circular saw blades having a defined cutting edge portion that is inclined from a leading point at the bottom of the cant to a trailing point at the top of the cant. The point of pivot of the saws is between the leading point and the trailing point of the cutting edge portion. The saw assembly is mounted on pads having a low coefficient of friction. Pressurized air and lubricant are delivered to the pads to reduce the friction.
