The leveling roller contains a single horizontal axis located perpendicular to the direction of travel, side discs on which a hollow cylinder is installed. Annular sealing elements are installed at equal intervals on the outer surface of the hollow cylinder. The annular sealing elements have the shape of an equilateral triangle in cross-section. Pointed rippers are installed diametrically between the annular sealing elements on the outer surface of the hollow cylinder.
