ABSTRACT:
A method of controlling the clearance angle of a veneer knife in a veneer lathe under a spindleless condition is applied to a veneer lathe that includes the veneer knife, at least three rollers, feed mechanisms coupled to at least two of the rollers for feeding the rollers, and a drive system coupled to at least one of the rollers for rotatably driving thereof, wherein the rollers to which the drive system is coupled supplies all the driving force required for rotating the log while each roller to which the feed mechanism is coupled are fed to hold the log while the log is peeled by the veneer knife. The method comprises the steps of setting a shifting amount based on a predetermined reduction in the diameter of the log from a predetermined first diameter to a predetermined second diameter and automatically shifting the rotational axis of the log in the direction perpendicular to the plane extending between the rotational axis of the log and the cutting edge of the veneer knife by the shifting amount during veneer peeling.
