LOG PROCESSING APPARATUS Abstract of the Disclosure A method and apparatus of processing logs prior to further processing in lumber, plywood, pulp or veneer mills. In the apparatus, logs are deposited into a cradle formed between a rotating cutter drum and support rollers which guide the log against the cutting drum and rotate the log about its longitudinal axis in a direction opposite to the rotation of the cutter drum, at a controlled speed slower than the drum. Constant rotation of the log reduces horsepower requirements by minimizing the length of each cut made by cutter assemblies extending from the cutter drum. Logs are discharged by lowering the guide rollers with respect to the cutter drum. A second embodiment is disclosed including a pair of cooperating rollers providing a variable sized cradle adjacent to the cutter drum. Means for delivering logs to the apparatus and for removing material cut from the log are disclosed. In a single operation, logs are debarked, rounded, reduced to any desired diameter, or completely reduced to chips.
