Abstract: A log handling and cutting system which cuts logs into lengths, and allows for maximum use of fiber. The system includes equipment for singulating the logs, optimally removing the bark from the logs, scanning the true log image, cutting the logs to length, and sorting the cut logs arranged in a sequence of coupled operations. The logs are singulated using a dual quadrant singulation system to provide maximum singulation reliability, thereby allowing a single operator to attend to this process. Once singulated, the logs are fed automatically into a debarker where the diameter and volume are scanned and debarker-operating parameters are set for optimum bark removal. The log is then scanned, tree length, using a unique scanning system, which determines the true image of the log. This enables the determination by computer of the optimum bucking solution of the log as well as a proper sorting of the optimum random lengths.
