The invention relates to an apparatus for debarking logs or preparing logs for separately performed debarking - especially logs (1) that are difficult to debark - the apparatus comprising a number of blades (11), the blades being arranged to cut or tear the bark of the logs (1) to be treated transversely with respect to the longitudinal direction of the logs, in order to facilitate the peeling of the bark, and especially its peeling as pieces of suitable size during the said preparation or the subsequent actual debarking treatment. The apparatus comprises a drum (3) rotated about its central axis (2), through which drum the logs (1) to be treated are fed, and inside the surface limited by the cylindrical inner sleeve (4) of which drum (3) is arranged to project a number of blades (11). The blades are arranged to cut or tear the surface of the logs (1) to be treated by the effect of the mutual movement of the drum (3) and the logs (1). On the inner sleeve (4) of the drum (3) is provided a through hole (20) for each blade (11), which means that the blades are arranged to be replaced on the outside of the drum (3). |
