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.
Claims15
An apparatus for removing bark from a log flow to be fed into the apparatus, wherein the apparatus includes a number of bark separation units, each of said bark separation units comprising an aggregate of a toothed disc mounted for rotation on a first disc shaft and a smooth-surface disc mounted for rotation 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 a rotation thereof and at a distance from each other, and 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 an axial direction of the disc shafts.
An apparatus for removing bark from a log, comprising:
- means for moving said log in a feeding direction;
- and
- a plurality of bark separation units, each said bark separation unit including;
- a rotatable first shaft;
- a toothed disk mounted to said first shaft at a first axial position;
- a rotatable second shaft spaced from said first shaft;
- and
- a smooth-surface disk mounted to said second shaft at a second axial position offset in relation to said first axial position.
