Abstract

The invention relates to a method in the process of timber debarking, whereby the debarking apparatus used comprises a rotary cylindrical drum (2), preferably equipped with transfer elements therein. The logs are conveyed from the feed end to the exit end of the cylindrical drum (2), the bark being thus separated from the trunk part of the logs. The cylindrical drum (2) is supported on a solid frame (1) by elements (4) which are suitably arranged to rotated substantially around the longitudinal axes of the cylindrical drum and at least part of them are flexible. The debarking apparatus comprises also drive means (6, 6a) for effecting the rotational movement of the cylindrical drum (2). The method is used particularly to measure the volumetric efficiency in order to control the process quantities of the debarking process. In the method, the control logistics of the volumetric efficiency are chosen according to the process quantities, particularly the elected barking strategy, in a way that they are dependent on the change of form of the flexible means (4). According to the method, the change of form of the flexible elements (4) - at least one of them - is measured preferably continuously during the use of the debarking apparatus for use in achieving at least one control quantity (A, B, C) according to the barking strategy.
