ABSTRACT:
An apparatus for controlling the knife carriage feed is disclosed herein which is applicable to a centerless type veneer lathe wherein a peeler log is driven to rotate by peripheral drive system without use of conventional spindles. The apparatus includes a roll which is engageable with the peripheral surface of a log to be rotated thereby for measuring the current log peripheral speed and a device connected to a carriage feeding screw for monitoring the current log diameter. The knife carriage feed is effected in accordance with the log rotational speed which is determined by the current log diameter and the current log peripheral speed so that a veneer knife on the carriage cuts into the log peripheral surface for a predetermined distance for each turn of said log.
