TITLE A METHOD OF KERFLESS CUTTING WOOD INVENTORS John S. Johnston Andr? St-Laurent ABSTRACT OF THE DISCLOSURE To reduce splitting ahead of the knife blade and the deflection of the cut from a straight line during kerf- less cutting, the wood is compressed only on either side of the knife blade and the cutting edge of the knife blade is inclined rearwardly to prevent the wood fibres from leaving and blunting the blade. Preferably the knife blade cutting edge inclines rearwardly from both ends towards the centre because this imparts rigidity to the knife blade. The wood may be compressed by passing between side pads on each side of the knife blade or by passing between rotatably mounted fluid pressurized tires.
