The invention concerns a method for the continuous coating of at least one metal strip (1) with a fluid cross-linkable polymer film free from solvent or diluent and having a thickness less than that of the metal strip. The invention is characterised in that it consists in the following steps: continuously moving the metal strip (1) on at least one support roller (3), pre-heating said strip, forming by forced flow, on a ductor roller (16) a lap (30) of said cross-linkable polymer, heating and driving in rotation the ductor roller (16) in the same direction as the support cylinder (3) and forming the cross-linkable polymer film, compressing, between the ductor roller (16) and the metal strip (1), an applicator element (17) with deformable surface, heated and driven in rotation in the same direction as the support cylinder (3) to transfer said film from the ductor roller (16) onto the applicator element (17) and from said applicator element onto the metal strip (1). The invention also concerns a coating device for implementing said method.
L'invention a pour objet un procédé de revêtement d'au moins une bande métallique (1) par un film en polymère réticulable fluide exempt de solvant ou de diluant et d'épaisseur inférieure à celle de la bande métallique, caractérisé en ce que l'on fait défiler en continu la bande métallique (1) sur au moins un cylindre de support (3), on préchauffe ladite bande, on forme par écoulement forcé, sur un cylindre preneur (16), une nappe (30) dudit polymère réticulable, et on chauffe et on entraîne en rotation le cylindre preneur (16) dans le même sens que le cylindre de support (3) et on forme le film en polymère réticulable, et on comprime, entre le cylindre preneur (16) et la bande métallique (1), un élément applicateur (17) de surface déformable, chauffé et entraîné en rotation dans le même sens que le cylindre de support (3) pour transférer ce film du cylindre preneur (16) sur l'élément applicateur (17) et dudit élément applicateur sur la bande métallique (1). L'invention a également pour objet un dispositif de revêtement pour la mise en oeuvre de ce procédé.
