Claims18
A feed roll comprising:
- a roll member having a rotary axis and an outer surface;
- two complementing sets of flutes fixed on the roll member;
- wherein each of the sets of flutes comprises:
- a set of mounts circumferentially spaced apart around the outer surface of the roll member, each of the mounts comprising an elongated body, the body comprising a base portion having a radially inner edge fixed on the roll member and a backing portion unitary with the base portion, the backing portion extending longitudinally along the base portion and extending radially outward of the base portion along one side of the base portion, the base portion and the backing portion configured to form a seat on a seat side of the mount that is opposed to an opposing side of the mount, the seat extending longitudinally along the mount and defined at least in part by a radially outwardly oriented outer face of the base portion that is spaced radially outwardly from the outer surface of the roll member, and a mounting face of the backing portion extends longitudinally along the mount and extends radially outward of the outer face of the base portion and is oriented substantially perpendicularly thereto,
- wherein the outer and mounting faces extend substantially in a direction along the length of the mount and the mounting face of the seat of each of the mounts faces the opposing side of an adjacent mount of the set of mounts;
- and
- replaceable flute elements detachably and matingly engaged in the seats of corresponding mounts of the set of mounts, each of the replaceable flute elements having a radially inward face engaged against the outer face of the base portion, a backing face engaged against the mounting face of the backing portion and an outer longitudinal edge formed with a traction element for gripping logs, wherein the mounting face of the backing portion and the outer face of the base portion each extend along the full length of the replaceable flute element and the replaceable flute element extends along the length of the seat and radially outward beyond the mount.

A kit for retrofitting a feed roll, the kit comprising:
- a set of mounts, each of the mounts comprising:
- an elongated body comprising a base portion having an arcuate radially inner edge configured for attachment to an outer surface of the feed roll;
- and
- a backing portion unitary with the base portion that together defines a seat, the backing portion extending longitudinally along the base portion and extending radially outward of the base portion away from the inner edge along one side of the base portion;
- the seat extending longitudinally along the mount and defined at least in part by a radially outwardly oriented outer face of the base portion that is opposed to and spaced apart from the inner edge and a mounting face of the backing portion that extends longitudinally along the mount and extends away from the outer face of the base portion and is oriented substantially perpendicularly thereto, wherein the outer and mounting faces extend substantially in a direction along the length of the mount;
- and
- a set of complementing replaceable flute elements matingly engageable with the seats of corresponding mounts of the set of mounts, and each of the replaceable flute elements having a radially inward face engageable against the outer face of the base portion of a corresponding one of the mounts, a backing face engageable against the mounting face of the backing portion of the corresponding one of the mounts, and an outer longitudinal edge formed with a traction element for gripping logs, wherein the mounting face of the backing portion and the outer face of the base portion each extend along the full length of the replaceable flute element, and the replaceable flute element, when engaged in the seat of the corresponding one of the mounts, extends along the length of the seat and radially outward from the outer face of the base portion beyond the mounts.
