The invention concerns a method and arrangement for forming stacks of timber where the pieces of timber are end-aligned through interaction with transverse rollers, and are formed into stacks through layers being stacked one of top of each other with, in some cases, the insertion of intermediate laths. In order to achieve higher capacity, the method includes the following operational steps: - that in a first step pieces of timber (3) form a contiguous layer (20), - that in a second step the pieces of timber in the layer (20) are separated from each other - that in a third step the separated layer (20) is divided into a number (n) of pre-determined sublayers (20:1-20:n) of pieces of timber, - that in a fourth step the sublayers (20:1-20:n) are end-aligned against a first end stop (37), - that in a fifth step any one of the sublayers (20:1-20:n) is end-aligned against a second end stop (38), - that in a sixth step the relevant sublayers (20:1-20:n) are collected to form a contiguous layer (20), - that in a seventh step the contiguous layers (20) are stacked one on top of each other to form a stack of timber. |
