Abstract
An improved lifter and a method of repairing a damaged lifter employed in a rotary drum debarker of the type which removes the bark of logs by introducing logs into a rotating drum wherein the the logs tumble and flail against one another so that the bark is removed by the tumbling and rubbing action of one log against another. A plurality of lifters are arranged around the interior surface of the drum so that the point or vertex of the lifter is facing toward the axis of rotation of the drum. The lifters are provided with cleats on the vertex of the lifter in the direction of rotation of the drum to protect the lifter from excessive wear. In addition the cleat lifts the logs higher in the drum which improves the tumbling action. Damaged lifters may be repaired by the addition of the cleat to the vertex of the lifter.
