ABSTRACT:
A method of sawing a wooden workpiece makes simultaneous use of a chip cung operation with chip cutting saw teeth provided along the leading edge of a saw blade and a cutting operation with knife edges provided on the same leading edge of the saw blade. Between each pair of adjacent chip cutting saw teeth on the leading edge of the saw blade a knife edge, also provided on the leading edge of the saw blade, is fed into the workpiece together with the saw teeth in a plane located within the kerf made by the saw teeth and in such a position relative to the saw teeth that this knife edge cuts into the workpiece or at least into the chip, which still adheres to the workpiece and is being formed by the one saw tooth, and cuts this chip into two portions, which when liberated from the workpiece under the action of the saw tooth are distributed on opposite sides of the saw blade into the clearances between the side surfaces of the saw blade and the wall of the kerf.
