Abstract
Application of a graphite film to at least the first roll contacted by a metal strip to which a coating metal has been applied. The roll may be scraped clean and the graphite film applied immediately after scraping. The graphite film may be applied by wiping the roll with a solid graphite block or by wiping the roll with a graphite colloidal suspension in a suitable carrier. In the latter event, the roll temperature must be high enough to vaporize the carrier so that strip contamination is avoided. The graphite film prevents adherence of coating metal particles to the roll surface whereby damage to the coated surface on the metal strip is prevented.
