Abstract:
1. A method for removing bark from logs in a log debarker having an open ended chute formed between opposing support surfaces, wherein one of the support surfaces includes a plurality of debarking shafts arranged side-by-side and in a debarking plane and the one of the support surfaces further includes an offset debarking shaft parallel to and adjacent one of the debarking shafts in the debarking plane, the method comprising: advancing the logs through the chute of the log debarker in a direction generally parallel to debarking shafts and the debarking plane; rotating the debarking shafts which include debarking teeth that cut bark from logs abutting the rotating shafts; rotating at least the offset debarking shaft at a faster rotational speed than the rotational speed of one or more of the debarking shafts in the debarking plane; by rotating the debarking shafts, deflecting logs and bark removed from the logs upwards while in the chute, and discharging the removed bark from the chute and over the rotating offset debarking shaft.
