ABSTRACT:
A lot of concave portions and convex portions are formed on a circumferential face of base metal cylinder or roller. Summits of the convex positions are ground and removed or erased. The base metal cylinder or roller is plated and coated to harden the circumferential face. The concave portions and the convex portions leave their shapes after the plating and coating process. Additionally, the plated and coated ends of the convex portions are ground in order to form flat faces or curved faces of ends, on which flat faces or curved faces a film web or tape web slides. The metal roller is used in a machine handling film or tape or any web material.
