ABSTRACT:
A grain chill roller is manufactured by electroplating a layer of copper onto the surface of the roller. The layer of copper is than abrasively blasted with glass beads to produce surface features of a substantially uniform depth, and then the surface is abrasively blasted with small particles of silicon dioxide to modify the pattern of features formed by the previous blasting operation. The resulting surface is bright nickel electroplated to level the down pattern of the surface without eliminating the down pattern. The roller is used in the manufacture of resin coated photographic paper, for example.
