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.

A vacuum-coating system for coating a strip-shaped metal material, comprising:
- a conveying section with transport rollers, on which the strip-shaped metal material is movable in a transport direction, the transport rollers being configured to convey the strip-shaped metal material with a width of the strip being horizontally arranged;
- and
- a coating chamber in which a vacuum can be generated, the coating chamber having an inlet area and an outlet area through which the strip-shaped metal material passes in the transport direction,
- wherein a trimming shear is arranged upstream of the coating chamber, with which trimming shear the strip-shaped metal material is trimmed at at least one strip edge,
- wherein the trimming shear is configured to produce a constant width of the strip-shaped metal material over its longitudinal extension, and
- wherein a strip position control device is arranged upstream of the trimming shear, with which the strip-shaped metal material can be aligned with respect to a center of the conveying section.
A method for coating a strip-shaped metal material (11), comprising:
- moving the strip-shaped metal material with its width being horizontally arranged over a conveying section in a transport direction;
- vacuum-coating the strip-shaped metal material within a coating chamber in which a vacuum is applied;
- and
- trimming the strip-shaped metal material with a trimming shear upstream of the coating chamber at at least one strip edge;
- producing a constant width for the strip-shaped metal material over its longitudinal extension;
- and
- aligning the strip-shaped metal material with respect to a center of the conveying section by a strip position control device which is arranged upstream of the trimming shear.
