Abstract

A roller with a doctor blade has both a harder material portion and a softer material portion provided on the peripheral surface in the same radius from the center of the roller, for achieving complete doctoring. The harder material portion forms a minimum belt-like line in a non-perpendicular direction with respect to the axis of the roller, and preventing wear by doctoring against the softer material portion, and limits the wear of the doctor blade, producing uniform wear without a fear of local wear. The softer material portion has maximum area provided between the turns of the belt-like line and facilitates the formation of cells for measuring and the use of a lipophilic material.
