Abstract
A method for the continuous coating of at least one metal strip with a fluid, crosslinkable polymer film free from solvent or diluent and having a thickness less than that of the metal strip. The process firs continuously moves the metal strip on at least one support roller, pre-heats the strip, forms by forced flow, on a pinch roller on a lap of the crosslinkable polymer, heats and drives in rotation the pinch roller in the same direction as the support roller, and forms the crosslinkable film by compressing, between the pinch roller and the metal strips, an applicator element with a deformable surface, heated and driven in rotation in the same direction as the support roller to transfer the film from the pinch roller onto the applicator element and from the applicator element onto a metal strip. A coating device for implementing this method is also disclosed.
