Abstract
A method of controlling the feed of the backup rolls of a log backup apparatus for use in a veneer lathe for preventing a log from bowing while veneer is peeled from the log. The method comprises the step of centripetally feeding the backup rolls from a control-start diameter .PHI. at a provisional feed rate f which is higher than a predetermined feed rate F by a feed rate of a pre-selected correction value .alpha. per log rotation. The aforementioned control-start diameter .PHI. is slightly larger than the diameter of the log at which the backup rolls are brought into contact with the log. The method further comprises the steps of stopping the centripetal feeding of the backup rolls at the provisional feed rate f when the bowing is eliminated from the log and thereafter centripetally feeding the backup rolls at the predetermined feed rate F, thereby eliminating the bowing that occurs during the veneer peeling from the log.
