Abstract
An apparatus for removing bark from a wood and bark containing log flow. The apparatus includes a number of bark separation units, each of the bark separation units comprising an aggregate of a toothed disc mounted on a first disc shaft and a smooth-surface disc mounted on a second disc shaft. The disc shafts are set crosswise relative to a feeding direction A applied to the log flow by the toothed disc upon the rotation thereof and at a distance from each other. The toothed disc and the substantially smooth-surface disc of a bark separation unit are set in a staggered fashion relative to each other in the axial direction of the disc shafts.
