Procedure for working tree trunks by machining into wood products, such as boards and cants. In the procedure, from trunks (1) preferably trimmed on at least two sides, at first at least one side board (3) is sawn so that at least part of the dull edge (2) remains on the side board (3), whereupon the dull edges (2') of the side board are edged. The side board (3) is moved together with the central section (1') during the edging operation and the side board (3) and the central section (1') are kept at a distance from each other by means of a separating element (6), such as a dividing knife, at least during the edging operation.
