| 摘要 |
<p>The invention concerns a method for continuously coating at least one surface of a metal strip with a single-layer or multilayer crosslinkable polymer fluid film (20) obtained from solid precursors at room temperature and free of non-reactive solvent or diluent and whereof the softening temperature is higher than 50 °C. The method consists in continuously unwinding the metal strip (1), preheating said metal strip (1) at a temperature substantially equal to or higher than said crosslinkable polymer softening temperature, forming by forced flow on an applicator roll (12) with deformable surface a single-layer or multilayer coat (13) of said crosslinkable polymer, driving in rotation the applicator roll in the same direction as that of the unwinding of the metal strip (1), heating the applicator roll (12) to a temperature higher than the temperature for forming the coat and transferring said coat onto the metal strip to form the single-layer or multilayer film (20) on the corresponding surface of the metal strip (1). The invention also concerns a coating device for implementing said method.</p> |
