Abstract
Apparatus for debarking a log using the compression debarking technique includes rollers which apply radial pressure to the log to separate the bark from the wood of the log. Three double-cone rollers, each having its double cones tapered to the middle of the roller, are arranged with their axes of rotation at substantially 60.degree. to each other and perpendicular to the direction of travel of the log through an aperture defined by the three rollers. Pressure is applied to the bark of the log by the double-cone rollers. The apparatus may include cutting means, such as a knife blade on the outer surface of all three of the double-cone rollers, which slices the bark which has been separated from the wood of the log by the pressure applied by the rollers, so that strips of bark fall from the log. The invention is especially suitable for removing thick stringy, fibrous bark from logs.
