Abstract (en)
[origin: WO8705555A1] The tree-trunks (3) to be fed to a processing machine (23) pass through several sequentially arranged sets (5-10) of centrally feedable centering rolls (11). During this operation, the centering rolls (11) which are located at the start and end of the trunk are brought into engagement with the trunk (3). Cutters (20) arranged downstream cut guide surfaces (21) on the tree trunk (3) on which the tree-trunk is then immediately supported and guided by guide elements (22).
