Abstract

A continuous method for surface treatment of metal strips applies a finish coat having a thickness of not more than 3 μm, the apparatus employed for application being equipped with at least one IR sensor which faces a coated side of the strip, operates in reflection geometry, and serves to measure the coat thickness of the finish coat, with the strip running.
