A novel barker assembly which in one disclosed embodiment comprises a shell including a stationary housing and rotatable drive rings which are supported on trunnion rollers and located in spaced-apart slots in the housing, the drive rings being rotatably driven in excess of about 7.5 RPMs by suitable drive means. An inner portion of the housing forms a "battering" wall against which the logs are deflected by deflector means to assist in debarking as well as to absorb a major portion of the force of the logs to protect the drive rings. Each drive ring is provided with inwardly projecting pusher elements to move the logs around the contour of the housing. A grillage is provided in the bottom of the housing to permit removal and subsequent conveyance of bark therefrom in a more useable form. High speed roller assemblies are provided for introducing the logs into the barker assembly and to withdraw debarked logs. |
