Feed rolls having flute assemblies of matingly engageable mounts and flute insert elements

In combination, a replaceable flute element for a feed roll,

• and a mount with a seat shaped to matingly engage with the flute element,
• the flute element comprising
• a unitary elongated plate body having an inner longitudinal edge, an outer longitudinal edge, and a flat backing face extending between the inner longitudinal edge thereof and the outer longitudinal edge thereof, the inner longitudinal edge of the plate body extending perpendicular to the backing face of the plate body so as to matingly engage in the seat of the mount on the feed roll, the outer longitudinal edge of the plate body being formed with a traction element configured to grip an outer surface of a log, and the plate body having one or more bolt holes therethrough for passing bolts therein to secure the plate body to the mount;
• and
• wherein the mount comprises one or more u-shaped sections in a longitudinal cross-section and is L-shaped in a lateral cross-section.

In combination:

• i) a replaceable flute element for a feed roll, the flute element comprising:
• a unitary elongated plate body having an inner longitudinal edge, an outer longitudinal edge, and a flat backing face extending between the inner longitudinal edge and the outer longitudinal edge, the inner longitudinal edge extending perpendicular to the backing face for matingly engaging in a seat of a mount on the feed roll;
• the outer longitudinal edge being formed with a traction element configured to grip an outer surface of a log;
• the plate body having one or more bolt holes therethrough for passing bolts therein to secure the plate body to the mount;
• the plate body having first and second ends and being tapered such that a distance between the inner longitudinal edge thereof and the outer longitudinal edge thereof is smaller at the first end of the plate body than at the second end of the plate body;
• wherein the first end and the second end of the plate body extend parallel to each other;
• wherein the inner longitudinal edge of the plate body is outwardly concave;
• and
• wherein corners between the inner longitudinal edge of the plate body and the first end and the second end of the plate body of the replaceable flute element are outwardly convex;
• and
• ii) said mount with said seat shaped to matingly engage with the flute element, wherein the ends of the plate body, the corners of the plate body, the inner longitudinal edge of the plate body and the flat backing face of the plate body are shaped to abut the seat of the mount.
