Abstract
An apparatus is provided for cutting lengths of debranched trees or logs into shorter pieces, comprising a conveyor for carrying the logs sideways to and past a plurality of cutters arranged in groups, the cutters in each group being individually movable between active cutting and inactive noncutting positions, and into cutting positions over a determined span, and spaced apart along the path of travel of the logs so that only one cutter at a time in a given group cuts a log. Beyond the cutters, a means is provided for classifying the logs according to quality and dimensions, and then separating the classified logs for further cutting into lumber, pulping, or other processing, according to the use to which the log can be put.
