Title: Method for coating a substrate with plastic

Abstract: A method is disclosed for coating a substrate or web with a plastic material. A liquid plastisol coating is applied to the web and the coated web is then passed between a put-on roll and a heat drum, which heats and cures the plastisol. The put-on roll is pressed against the heat drum to compress the coated web. The plastisol is partially cured to gelation while being compressed by the put-on roll, and the curing of the plastisol is completed during further travel of the web around the heat drum.
