Abstract:
A method of applying a multi-layer coating to a surface of an elongated strip article of variable thickness or surface height, which involves applying at least two layers of different coating materials in the form of solidifiable fluids onto said surface of said elongated strip article and reducing said layers to a desired thickness by causing said applied coating materials to encounter at least one coating surface that is movable substantially perpendicularly relative to said strip article and is urged towards said strip article in opposition to hydrodynamic force generated by said coating materials on said at least one coating surface, thereby accommodating variations in thickness of said strip article or differences of surface height without varying said coating thickness substantially, wherein said layers are applied one on top of another such that an outer layer is applied on top of an immediately underlying layer before said immediately underlying layer has solidified.
