<p>The peripherally driven veneer lathe comprises a knife (2), a knife carriage (1) on which the knife is mounted, a peripheral-drive member (4) and a member (3) for supporting a log (5). The peripheral-drive member has a plurality of drive members (4b) disposed at predetermined intervals in an axial direction and with rotational axes substantially parallel to the cutting edge of the knife. Each drive member has a number of piercing projections (4a) formed on its periphery. The cutting edge (2c) of the knife is positioned on a flank side at a predetermined distance away from a point of intersection of an extended plane of the cutting face and an extended plane of the flank, toward the downstream in the direction of rotation of the log. The cutting edge is also connected to the cutting face via a connecting curved surface. By mounting the knife on the knife carriage, the connecting curved surface is positioned away from the trajectory of rotation of the piercing projections with a predetermined gap when the peripheral-drive member is most closely positioned to the knife.</p> |
