An automatic log-cutting apparatus, or log merchandiser which is designed to analyze and rapidly process tree-length stems, or logs, into shorter segments for further processing in pole mills, sawmills, plywood plants and the like. The logs are loaded via a conveyor onto the support arms of a number of cutting stations, all of which are movable and pre-positioned according to the determined optimum cut locations. The logs are then cut by pivoting saw blades, and the cut segments are released by the support arms onto a conveyor for removal.

Why it's free to use
- Filed July 7, 1999 and granted October 21, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 7, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 7, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
