Abstract

The invention relates to a method and a vacuum-coating system (10) for coating a band-type material (11), in particular made of metal. For this, the band-type material (11) is moved, via a conveying section (12), in a transport direction (T) and is vacuum-coated within a coating chamber (14), in which a vacuum is applied. As seen in the transport direction (T) of the band-type material (11), at least one flatness optimization device (39) is arranged upstream of the coating chamber (14), through which flatness optimization device the band-type material (11) can be guided. In this way, a desired flatness is generated for the band-type material (11).
