ABSTRACT:
The invention is an infeed conveyor for a saw which enables feeding sweepy cants or logs in such a manner as to achieve a significant improvement in lumber recovery. The conveyor has at least one portion which can be configured between a straight line track and a curve which approximates an arc of a circle. The arc can be adjusted so that it approximates the sweep curvature of the log or cant which can then be guided into a saw along a path approximating it radius of curvature. The conveyor consists of a sharp chain having at least one portion running on a slide bar which can be configured to give the desired curvature. The conveyor can further be adjusted with regard to the following saw or saws to control offset. In its most preferred version a pair of chipper heads is located between the conveyor and saws to dress the upper and lower faces of an incoming cant into a gang cant of predetermined depth.
