ABSTRACT:
A ring debarker has counterbalanced swing arms on which rotary cutters are mounted. The counterbalancing of the swing arms is such that the centrifugal and gravitational forces on the swing arms as they rotate around a log being debarked are substantially neutralized so that debarking pressure exerted on the cutters can be accurately controlled by controlling air pressure used to bias the swing arms.
