ABSTRACT:
A system used in combination with a cant sawing or cutting unit, the function of which is to guide two faced-cants through the cut along the line of their natural curvature. The system comprises, at the infeed end of the unit, rollers for clamping the opposite planar faces of the cant, thus providing it with a pivotal point, and also includes means for causing an angular displacement of the forwardly moving cant, from said pivotal point and relative to the sawing or cutting elements, thereby allowing the elements to cut along the natural curvature of the cant.
