Abstract
A combination log debarking, log chipping unit having a debarking apparatus and a chipping apparatus mounted on a common chassis, the two apparatus are aligned for conveying logs from the debarking apparatus to the chipping apparatus. The two apparatus are separated by a space of about 6-10 feet to permit loose bark to be removed from the logs and thereby avoid bark contamination of the chip. A conveyor system between the two apparatus guides and conveys logs to the chipper. A single power source enables control over the feeding of the logs to synchronize log feeding with the chipper's chipping capability. A loader over the debarking apparatus provides convenient loading of the logs into the debarker. The power source and controls for the various operating components are all under the common control of the loader operator.
