Abstract
Debarking/delimbing apparatus comprises at least one spool device mountable and rotatably driven about an axis and capable of removing bark from tree parts moved lengthwise across its axis. Each spool device has two end members rotatable about the axis and each of which supports the ends of several shafts which extend between the ends members parallel with the axis and equally spaced from and around the axis. Each of said shafts has, spaced along its length, a series of solid debarking elements, each element being eccentrically and rotatably mounted on its respective shaft so that when the spool device is rotated centrifugal forces will cause the elements to project outwardly from the device so as to contact tree part, the elements being provided with protrusions for scraping off bark. The spool device is arranged so that all of said elements are completely rotatable about said shafts without interference with each other or with any part of the device.
