<p>The present invention concerns a circular saw blade assembly for a saw mill or similar apparatus used for sawing boards from logs, said circular saw blade assembly comprising at least two circular saw blades (2) attachable to and axially transferrable on a saw blade spindle (1) as well as one or several edge milling cutters for shaping the board to a correct width. The circular saw blade assembly in accordance with the invention is implemented so that the edging cutter is formed by edge cutter elements (3, 4) adapted to adjacent circular saw blades (2, 5), whereby the cutter elements are axially adjustable in relation to each other along with the spacing adjustment of the circular saw blades (2, 5), and each cutter element (3, 4) is comprised of one or several cutter knives (6) and a block section (7) having a recess machined to its face opposing the adjacent cutter element and having a penetrating hole for the saw spindle (1) to pass, whereby the knives (6) of the adjacent cutter elements (3, 4) are aligned to rotate along a single circle with an axial displacement of the elements at the different points along the cutting circle.</p> |
