Abstract
The invention concerns a method for continuously coating at least a metal strip with a crosslikable polymer fluid film free of non-active solvent or diluent and whereof the softening temperature is higher than 50° C. The method consists in continuously unwinding the metal strip ( ) on at least a back-up roll ( ); forming, on a roll ( ) by forced flow, a layer of said crosslinkable polymer in melted state; forming, from said layer ( ), said crosslinkable polymer film ( ); and transferring entirely in thickness said film onto the metal strip ( ) and, between the zone forming the layer ( ) on the roll ( ) and the zone applying the film ( ) on the metal strip, in thermally conditioning the crosslinkable polymer to reduce its viscosity. The invention also concerns a coating device for implementing said method.
