Abstract
A combination debarking/delimbing and chipping machine for processing logs is mounted on a single chassis. The debarking/delimbing apparatus of the machine has a lower flail positioned below a material feed path and two adjustable flails positioned above the material feed path. The upper flails will adjust to the size of a log fed into the machine. The provisions of two upper flails assures total removal of bark/limbs from the log and aids in discharging loosened bark. The upper flails may be driven at variable rates and may be reversibly driven. The provisions of two upper flails enables a reduced rotational speed of the flails which enhances flail life.
