A method and an apparatus for handling logs (6) to be debarked so that the surface of the logs is torn or cut by means of blades (15) moving under the logs in relation to the logs, said blades projecting upwards from the bottom (13) carrying the logs. The direction of the mutual cutting motion between the logs and the blades deviates from the longitudinal direction of the logs. The blades (15) and the logs (6) are moved in relation to each other so that for part of the time the logs are out of contact with the blades, higher up than the cutting edges of the blades, and for part of the time the logs are in contact with the cutting edges of the blades.
L'invention concerne un procédé et un appareil de manutention de rondins (6) à débarquer. Cet appareil fonctionne de telle sorte que la surface des rondins est entaillée ou coupée par des lames (15) se déplaçant sous les rondins. Ces lames se projettent vers le haut à partir du fond (13) supportant les rondins. Le sens du mouvement de coupe réciproque entre les rondins et les lames dévie par rapport au sens longitudinal des rondins. Les lames (15) et les rondins (6) se déplacent les uns par rapport aux autres de telle sorte que pendant un laps de temps les rondins se trouvent en contact avec les lames, à un niveau plus haut que les bords de coupe des lames, et pendant un autre laps de temps les rondins sont en contact avec les bords de coupe des lames.
