There is provided a feed roll assembly according to one aspect. The assembly includes a feed roll and an elongate mount coupled to and extending radially outwards from the feed roll. The assembly includes an elongate mount with a recessed region extending from a distal edge towards a proximal edge thereof, extending from a first face towards a second face thereof, and extending between a pair of spaced-apart ends thereof. The assembly includes an insert shaped to matingly engage with the elongate mount via the recessed region of the elongate mount.

There is also provided a feed roll assembly according to another aspect. The feed roll assembly includes a feed roll, an insert and an elongate mount that couples the insert to the feed roll. The elongate mount is shaped to enclose a proximal edge, a backing face and spaced-apart ends of an inner portion of the insert.

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 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.
