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.

In combination with a fixed sawing unit equipped with elements for sawing two-faced cants having opposite planar faces, a system for directing a cant to follow, throughout the sawing process, its natural curvature comprising:
- means upstream of said fixed sawing unit for, rollingly clamping at the infeed end of the unit the opposite planar faces of said cant to provide a pivotal point for said cant at the point of clamping;
- and
- means downstream of said fixed sawing unit for causing longitudinally an angular displacement of the cant while said cant is guided at said pivotal point to thereby allow the sawing process to follow the natural curvature of said cant.
In combination with a unit equipped with elements for cutting two-faced cants having opposite planar faces, a system for directing a cant between fixed cutter heads in order to follow, throughout the cutting process, its natural curvature parallel to said planar faces, comprising:
- means upstream of said fixed cutter heads for rollingly clamping at the infeed end of the unit the opposite planar faces of said cant to provide a pivotal point for said cant at the point of clamping;
- and
- means downstream of said fixed cutter heads for causing longitudinally an angular displacement of a curved cant relative to the cutting unit whereby said cant is cut along a curve while being guided at said pivotal point to thereby allow the cutting process to follow the natural curvature of said cant.
