Abstract (en)
The invention relates to an improved method for processing a log, wherein the log is fed (101) onto a processing line (201) and advanced through the following process steps of: measuring (102) a log (T) three-dimensionally to find out its geometrical shape; storing (103) measurement data of the log (T), said measurement data being a basis for conducting the log treatment; checking a position of the log (T) and rolling (104) the log over for bringing a possible skewness (L) to face upwards; and aligning the log (T) and feeding it into a processing assembly (206; 2061, 2062) with the skewness (L) upward for carrying out processing of the log. The method further comprises supporting the log (T) from below at the site of skewness, while treating the log in the processing assembly (206; 2061, 2062), based on the measurement data, particularly curvature data of the log, stored in step b, such that a downward directed force effect applied to the log by the processing assembly (206; 2061, 2062) is compensated for entirely or partially at the site of said skewness. The invention relates also to an arrangement applying the method.
