Abstract
A chipping machine includes a debarking assembly, a chipper assembly, and a log advance system to conveys logs through the chipping machine and into contact with the debarking assembly and chipper assembly. A rotating chipper disk cuts chips from the log. A housing encloses the chipper disc and includes a spout that provides an exit path for chips out of the housing. The chipper assembly includes a first path for collecting bark and directing bark out of the machine. A second path that is separate from the first path collects trash and directs the collected trash to first path and out of the machine. An inlet of the second path is an opening formed in a base of the housing. The second path includes a chute onto which trash falls and then slides under the force of gravity to the first path.
