摘要： The invention relates to a method for cutting a log into pieces. The log is cut into pieces with at least two nearly diametrical cuts (S1, S2), where the outermost lie essentially symmetrically around the pith of the stock. Each so-obtained plank is edged (S7, S8) with the outer side as a reference for the trimming direction. Two planks are formed through a cut (S9, S10) being placed near to the pith essentially parallel with each edged outer side. The cutting is performed on the outermost part of the log with the alignment cut (S3, S4) essentially parallel with the nearly diametrical cuts (S1, S2) preferably in the same operation as the cutting into pieces with the nearly diametrical cuts. Each block with the alignment cut (S3, S4) is conveyed through at least one twin-bladed saw, the cuts of which are inclined with respect to the base surface of the block, for example 30° and cut essentially radially symmetrically around the position of the pith. This can be performed twice with different inclinations in a twin-bladed saw.
