  • Patent number: 4805677
    Abstract: An apparatus for removing bark from cut logs where the logs, stacked parallel to each other, are brought both to rotate and to move back and forth in the direction of their length during simultaneous movement sideways and in restacking. The movement of the logs is achieved by feeding the logs into a stationary container equipped with at least one level movable bottom section, a feeder side slightly sloped toward the bottom section, two planar, vertical gable sides and a discharge side sharply angled toward the bottom section. The bottom section of the container has at least one oblong section vertically and laterally movable, which, at its short end, is hung to rotate on eccentric shafts or the like.
