Abstract
Heat curable liquid polyvinylchloride plastisol or organosol resin is coated onto a porous fiber web in an amount sufficient to saturate the web. Liquid resin on one surface of the web is gelled by passing the web around a heated roll which, together with another heated roll, forms a compression nip. The web passes through the nip and around the second heated roll to gell the resin on the other surface of the web, after which the curing of the resin is completed in an oven.
