ABSTRACT:
The present invention comprises the combination of an elongated curved linebar with at least one saw. This arrangement enables "sawing-around-the-curve" so that increased recovery can be obtained from cants or logs having significant amounts of sweep. The linebar is positioned so that a tangent at the end adjacent to the saw is parallel to the plane of the saw. The linebar is preferably curved so that it approximates the average curvature of the cants or logs being fed to the saw. An auxilliary straight line bar, which is normally out of contact with an incoming cant, may alternatively be moved into position when the incoming cant is relatively straight sided.
