Abstract
A method and device for continuously coating at least a metal strip (1) with a crosslinkable polymer fluid film which is free of non-reactive solvent or diluent, and which has a softening temperature higher than 50° C. The method includes the steps of: continuously unwinding the metal strip (1) on at least a back-up roll (30); forming, by forced flow on an applicator roll (20) having a deformable surface, a layer of the crosslinkable polymer; and forming on the applicator roll (20) the crosslinkable polymer film and transferring the film from the applicator roll onto the metal strip. The device implements this method.
