Abstract
In order to increase the obtainable sawn timber volume in the side board region during the production of sawn timber from a tree trunk, in a method in which the tree trunk is canted at at least two sides, preferably four sides, a remaining wane region is milled out at at least two mutually opposite corner regions by milling tools, and a side product board is cut off by a saw cut along a plane bounded by the corner regions, it is provided that, to mill out the corner regions, the milling tools are moved relative to the tree trunk in an arc, predefined on the basis of a measurement of the tree trunk, by virtue of the fact that, during a feed movement of the tree trunk relative to the milling tools, said milling tools are adjusted so as to follow the arc.
