PAPER MACHINE ROLL AND A METHOD FOR MANUFACTURING THE SAME

摘要

A paper machine roll comprises a core member (1) and an elastic cover (2,102,202,302), wherein the surface of said elastic cover has varying wear resistance properties along the roll length. The roll is manufactured by a formation of a basic roll cover (2a) on a roll core member (1) by overlapping a plurality of layers (20-23) having different properties and grinding and/or machining the basic roll cover (2a) for achieving a cover surface which comprises along the length of the roll at least one zone constituted by the cross-section of one of the layers (20-23).
