ABSTRACT:
A timber processing machine comprising a hollow rotor provided with barking and lopping knives. A tree trunk to be processed is fed longitudinally through the rotor. A non-rotable guide ring is coaxially fastened to the rotor at the inlet side of the knives. The front edge of the knives is sharpened along that portion of the knives which extends radially inside the guide ring. Said guide ring forces the branches of the tree trunk fed into the rotor to be bent into positions in parallel with the tree trunk and the knives cut the bent branches into pieces as the trunk is fed through the rotor.
