Abstract
A flail assembly for a debarking machine includes a flail shaft that is adapted to be rotated about a flail axis of rotation. Attached to the flail shaft is a flail chain that includes a plurality of interconnected links, at least some of which have a polygonal cross-section.
Claims11
A flail assembly for a debarking machine comprising:
- (a) a flail shaft that is adapted to be rotated about a flail axis of rotation;
- (b) a flail chain comprising:
- (i) an attachment end that is attached to the flail shaft;
- (ii) a free end;
- (iii) a plurality of interconnected links, at least some of which have a polygonal cross-section, which polygonal cross-section comprises a closed plane shape having at least three linear sides, with all of such linear sides being defined by straight lines.

A method for removing bark from a log, said method comprising:
- (a) providing a flail assembly comprising:
- (i) a flail shaft that is mounted for rotation about a flail axis of rotation;
- (ii) means for rotating the flail shaft about the flail axis of rotation;
- (iii) a plurality of flail chains, each of which has an attachment end that is attached to the flail shaft and a free end, wherein each of said flail chains comprises a plurality of interconnected links, at least some of which have a polygonal cross-section, which polygonal cross-section comprises a closed plane shape having at least three linear sides, with all of such linear sides being defined by straight lines;
- (b) moving the log in a processing direction that is generally perpendicular to the flail shaft axis so that rotation of the flail shaft will cause the flail chains to contact the log.
