Abstract
The invention relates to a method for dividing sawn timber 1 and at the same time for preventing it from cracking during drying. In the method recesses are sawn in the timber prior to drying, which recesses have been placed according to the dividing points and extend to a depth such that board parts on either side of the recesses are connected to one another by bridges 3. The recesses 2 are made in that side 5 facing the heartwood and the dividing of the wood after drying is done by folding or breaking the bridges between the boards 4. <IMAGE>
