Abstract

See full text

A chain flail debarking apparatus including a flail chamber accommodating at least first and second rotatable flail shafts being supported on a movable flail assembly framework, and both of the first and second rotatable flail shafts having a plurality of chains, a disc chipper for receiving the debarked logs and trees from the flail chamber and generating wood chips having a desired shape and size, and a single drive for driving both the disc chipper and at least the first and second rotatable flail shafts in the flail chamber. A pivotable feed roller is located adjacent an inlet to the flail chamber for sensing a diameter of the logs and trees to be debarked and moving the movable flail assembly framework, relative to the base frame, so as to maintain the logs and trees being debarked in the flail chamber, substantially centered with respect to both the first and second rotatable flail shafts so that both upwardly and downwardly facing surfaces of the logs and trees being debarked are substantially equally treated.
