A piece (4) with a regular hexagon shape is cut from the log and then a section is cut out from this piece along a first saw line (7) extending at right angles to and intersecting with two sides of the hexagon, dividing the piece in two. At least one further saw line (16) extending in the length direction of the half piece at right angles to one of its is used to remove a further section (18). |
