<p>The roller has radially outermost contact regions lying on a cylindrical envelope. Protrusion parts are mounted on straight profile strips whose width is a fraction of the roller length, where the protrusion parts are fixed close to a roller surface and include desired density of a lining part. A base band (3) includes a rectangular cross section whose width is a fraction of the axial length of an occupied area. A base side of the cross section constitutes the base, and a support side is provided on a surface of the roller in the occupied area in closely adjacent helical windings.</p> |
