Abstract (en)
[origin: EP1038643A2] The tree trunks are cut in a pattern with non-parallel cutting planes in a saw train (29) with several saw stations (TA1, TB1) positioned behind each other along a conveyor track (31). The track has conveyors to move a tree trunk from one saw station to the next in such a way, that cut faces are formed, which are at non-vanishing angles relative to each other. In a max. number of saw stations, the tree trunk is cut on one side only or on non-parallel sides. A turning device (7) to turn a trunk around its longitudinal axis is positioned in front of a device (13,19,21) to cut a trunk into four quarters and supply these to the saw train.
