Abstract: A link for debarking trees comprising at least two linear sides, each linear side having an outer surface, an inner surface and a diameter; and at least two opposing deformed sides, each deformed side having an outer surface, an inner surface, an undeformed diameter, and a deformation having a diameter different than the undeformed diameter; the at least two opposing deformed sides connected to the at least two linear sides through convex corner sections, such that the inner surfaces of the at least two opposing deformed sides and the inner surfaces of the at least two linear sides together form an interior space. Multiple links may be arranged into a chain and the chain may be used in a flailing apparatus.
Abstract: A linkage element for a flail chain comprising more than two shank portions and more than two angled portions connecting the shank portions. The shank portions and angled portions define an interior space of the linkage element. A flail chain comprising at least one such linkage element forms a part of a flailing apparatus used to debark trees.
