Abstract: The present document describes a removable brake for a debarker arm having a working end with a debarking tool configured to remove bark from a log, the removable brake comprising a main body; a mounting surface for removably mounting the main body on the debarker arm; a leading edge on one end of the main body for causing the debarker arm to move from an inner position toward an outer position when the leading edge of the main body engages an end face of the log moving along a processing line toward the leading edge; and a brake portion on another end of the main body for increasing the resistance offered against the debarker arm while debarking the log.

Abstract: Plastic parts are formed to have a relatively high wall stiffness by utilizing a pair of spaced plastic plates. One of the plates may be a simple plate. The other plate has a plurality of ribs extending from a base. The ribs are welded to the other plate. Use of the ribs provides a relatively high degree of stiffness to the final molded plastic part, for a relatively lightweight part.
