ABSTRACT:
A hardened and chrome plated steel roller is shot-blasted with sharp-edged particles (e.g. of 300-400 mesh) to provide sharp-edged recesses on the roll surface, and then shot-blasted a second time with steel balls (e.g. of 30-40 microns) to round the sharp edges of the recesses, to provide a smooth, but low luster, surface.
