Abstract

A nose bar device for a veneer lathe which is equipped with a knife carriage movable toward and away from a log from which a veneer sheet is cut, and a knife mounted on the knife carriage and having at the tip end thereof a cutting edge extending horizontally across the direction in which the knife carriage is moved. The lathe further includes a plurality of nose bars juxtaposed along the cutting edge of the knife and mounted to a block which forms a part the knife carriage and is adapted to be movable independently of the knife carriage. Each nose bar has at the lower end thereof a pressure edge located adjacent to the cutting edge of the knife for pressing against the log periphery adjacent to the knife cutting edge. There is provided a mechanism for independently adjustably moving the pressure edge of at least one of the nose bars toward and away from the cutting edge of the knife.
