A debarking machine is provided with a plurality of rotors disposed in parallel, and a gap between the rotors is blocked by a comb-tooth shape partition plate. The debarking machine is further provided with a log accommodating body, rotors rotatively mounted inside the log accommodating body and provided with debarking plates, a comb-tooth shape partition plate base disposed at a space between the rotors, a comb-tooth shape partition plate detachably mounted on the comb-tooth shape partition plate base, and a fixer for fastening the comb-tooth shape partition plate to the comb-tooth shape partition plate base. The comb-tooth shape partition plate is composed of partition plate elements divided along the axial directions the rotors, and each partition plate element is detachable separately. Thus the comb-tooth shape partition plates can be rebuilt and replaced easily.

A debarking chain having bent links; the bent links being bent either right or left, from end to end at a bend angle of from about 5 to about 90 degrees to provide a flail type debarking chain having protruding edges or corners that increase the efficiency in which bark is removed from logs during debarking operations. Bent link chains include right bent links that are bent to the right proximate the middle of the link, where the weld is preferably located, when the link is viewed from the side with the weld on the far side and left bent links that are bent to the left proximate the middle of the link, where the weld is preferably located, when the link is viewed from the side with the weld on the far side. Disclosed inventions also include a debarking drum having a plurality of debarking chains having at least two bent links, as well as debarking devices having such a debarking drum and methods of making and using the same. The debarking device preferably includes a chipping device and methods of using the same in conjunction with using such bent link debarking chain.

A feed roll comprises a roll having a rotary axis, flutes fixed on the roll, mounts fixed on the roll between the flutes, each mount having a seat spaced apart from the outer surface of the roll and replaceable flute elements detachably and matingly engaged in the seats of respective mounts and extending outward beyond the mounts. The replaceable flute insert element comprises an elongated plate body having an inner longitudinal edge, an outer longitudinal edge, and a backing face extending between the inner longitudinal edge and the outer longitudinal edge and the inner longitudinal edge and the backing face configured to matingly engage the seat of the mount. The flute insert element further comprises the outer longitudinal edge being formed with a traction element and the plate body having a plurality of bolt holes therethrough for registering with the bolt holes of the mount element when the plate body and the seat are matingly engaged.

An apparatus for use in debarking logs that includes a debarking assembly for separating bark from logs as the logs are passed through the apparatus, such that the separated bark falls away from the logs. A contact surface catches falling bark that has been separated from logs by the debarking assembly. A pusher reciprocates over the contact surface and includes a first pusher face that pushes bark over the contact surface. A magnet reciprocates with the pusher and may be selectively activated and deactivated. When the magnet is activated, a magnetic field is provided proximate the first pusher face such that magnetically attracted portions in the bark that are brought within the magnetic field as the pusher reciprocates are magnetically attracted to the first pusher face by the magnetic field and are separated from the bark.
