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.

Abstract: A metal strip is guided on transportation rollers through a strip treatment installation. The installation includes successive strip movement control devices along a transportation direction. The strip movement control devices detect and adjust the position of the strip transverse to the transportation direction. A method for operating the installation includes: detecting the position of the strip transverse to the transportation direction by sensors of upstream strip movement control devices; identifying properties that influence the position of the strip transverse to the transportation direction of the strip by the sensors; assigning the identified properties of the strip to corresponding points or segments of the strip; and proactively adjusting the position of the strip transverse to the transportation direction at downstream strip movement control devices based on the properties for the corresponding points or segments of the strip identified by the upstream strip movement control devices.

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).

Abstract: A device for coating a metal strip substrate includes a guiding apparatus for guiding the strip substrate along a movement path. A first coating apparatus coats a first main side of the strip substrate with an electrostatically charged coating powder which is in a fluidized state. The first coating apparatus is arranged under a first path section of the movement path. A second coating apparatus coats a second main side of the strip substrate with an electrostatically charged coating powder which is in a fluidized state. A redirecting unit redirects the strip substrate between the first and the second coating apparatus in such a way that the strip substrate in a second path section travels oppositely to the strip substrate in the first path section. The second coating apparatus is arranged at least partly geodetically under the second path section.

Abstract: A method for coating a metal strip by means of a metallic substrate in a strip coating system, wherein the coating is carried out according to the principle of physical vapor deposition and the layer thickness is set via the parameters of the strip speed and the vaporization rate. It is provided according to the invention that in the event of a layer thickness change and/or a width change of the metal strip, the vaporization rate and the strip speed are changed simultaneously, so that the layer thickness change can be implemented directly independently of the thermal vaporization process.

Abstract: A method for rinsing an overflow chamber at the bath-side end of a snout of a device for hot-dip coating a metal strip is presented. The snout guides the metal strip in a protective gas atmosphere before the metal strip is coated with a metal melt. A rinsing cycle is carried out in the overflow chamber of the snout by feeding metal melt from the molten bath into the overflow chamber and at the same time, sucking and pumping said melt out of the overflow chamber back into the molten bath. This rinsing cycle can be performed even when the snout has been retracted from the melt by supplying the melt from the molten bath to the overflow chamber with a delivery pump.
