Abstract
A method and a vacuum-coating system (10) for coating a strip-shaped material (11), in particular made of metal, are disclosed. Thereby, the strip-shaped material (11) is moved over a conveying section (12) in a transport direction (T) and vacuum-coated within a coating chamber (14) in which a vacuum is applied. When viewed in the transport direction (T) of the strip-shaped material (11), at least one trimming shear (38) is arranged upstream of the coating chamber (14), with which the strip-shaped material (11) is trimmed at at least one strip edge, preferably at both strip edges, in order to produce a constant width for the strip-shaped material (11) over its longitudinal extension.
