Abstract

A peripherally driven veneer lathe employs a knife with an improved shape which increases the deflection resistance of the cutting edge and improves its cutting ability. A cutting edge ( ) is positioned on the flank side a predetermined distance (H) away from a point (X) of intersection of an extended plane of a cutting face ( ) and that of a flank ( ) of a knife ( ) toward the downstream of the rotation of a log. The cutting face immediately following the cutting edge ( ) is formed as a connecting curved surface ( ) coinciding with a concentric arc distanced from the trajectory (G) of rotation of piercing projections ( ) of a peripheral-drive member ( ) with a predetermined gap (S). Preferably, the angle (&agr;) formed by a line (D) tangent to the connecting curved surface ( ) at the cutting edge and the flank ( ) is roughly equal to the sharpness angle (&bgr;: 18° to 25°) of the conventional knife.
