Title: Method and apparatus for bucksawing logs

Abstract: Previous methods of bucksawing logs slow the throughput of a sawmill in that the conveyor line is stopped while a given log is bucksawed to length. The present invention provides a method for bucksawing a log which improves the throughput speed, comprising the steps of a) advancing the log endwise along an infeed conveyor; b) raising the log above the level of said infeed conveyor while advancing the log; c) measuring the advance of the log while raised; d) stopping the log at the desired length; e) sawing the log to produce a forward log segment; and f) lowering the forward log segment onto an outfeed conveyor while advancing the remaining log segments. An apparatus for carrying out the method is also disclosed.
