ABSTRACT:
A method for sawing logs to obtain unit stacks of boards of a desired number of boards of a same cross section. The logs are presorted by diameter into groups within which each log selected has a sawing yield of a number of boards of a same cross section. The logs are fed from one or more groups to a saw mill for sawing them longitudinally and equal in number to yield a number of boards of a same cross section from the center yield thereof equal to a stack unit of the desired number of boards of the same cross section. The boards obtained by sawing are stacked as a stack unit of the desired number of boards without further sorting.
