| 摘要 |
The invention concerns a sawing method for compensating drying spirality of sawn timber. According to the invention, the drying spirality of a sawing blank and/or sawn timber sawn from a tree trun (1) is measured or estimated, and the tree trunk (1) is sawn with a counter spirality compensating the drying spirality, wherein the sawn surface (8) turns around the tree trunk so, that the angle (K) between the line segment (11) defined by saw blades/blade edges (2) and the comparative line segment (10) defined by the center point (6) of the cross-sectional profile of the tree trunk changes. The invention also concerns a sawing apparatus for compensating the drying spirality of sawn timber.
