Abstract: A process and apparatus are described wherein an integrated saw mill includes conveyor means for feeding debarked logs, classifying the logs and storing them according to size, advancing a particular log, scanning and analyzing the log and determining its cut pattern, squaring off the log by chipping heads, collectively cutting the log in line in accordance with the predetermined cut pattern, simultaneously advancing on separate conveyor means each piece of lumber so produced, sorting and storing each piece of lumber in accordance with its size, and further discharging the lumber onto a sticker-stacker for transferring stacks to drying kilns.
