The disclosure describes a system which in combination with a unit used to saw or cut to length cants serves to guide two-face cants during cutting along their natural curve line. The system includes on the feed side and ejection side of the unit means of laterally moveable rollers which press against the two opposite faces of the cant and pivot it in a horizontal plane as cutting progresses thereby causing the saws or knives to follow a controlled curve in relation to the natural curve of the said cant.

Why it's free to use
- Filed August 29, 1997 and granted April 1, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 29, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 29, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
