Problems solved by technology

If the strip-shaped material has an inconstant width over its length, this can lead either to increased wear or even to a break in the vacuum in the region of the partition of the vacuum chamber, thereby impairing the coating process in vacuum

Embodiment Construction

[0025] The invention provides a vacuum coating device 10 with which a strip-shaped material 11 can be provided with a coating on at least one side thereof, preferably on both sides (upper side and lower side). Accordingly, a method can also be carried out with such a vacuum coating system 10 for coating, in particular, a strip-shaped material 11 . Identical features are provided with the same reference numerals in both figures. It should also be pointed out here that the figures are only simplified and in particular not shown to scale.

[0026] The strip-shaped material 11 can consist of metal, in particular steel or high-grade steel or corresponding alloys thereof. Furthermore, it should be pointed out that the strip-shaped material 11 coated with the vacuum coating device 10 can be a hot-rolled strip (Warmband) or a cold-rolled strip (Kaltband).

[0027] Next, the vacuum cladding equipment 10, its various components and its working principle are explained in detail:

Abstract

The invention relates to a method and a vacuum-coating system (10) for coating a strip-type material (11), in particular made of metal. For this purpose, the strip-type material (11) is moved along aconveying section (12) in a transport direction (T) and is vacuum coated inside a coating chamber (14) in which a vacuum is applied. When viewed in the transport direction (T) of the strip-type material (11), at least one set of trimming shears (38) is arranged upstream of the coating chamber (14), with which the strip-type material (11) is trimmed on at least one strip edge, preferably on both strip edges, in order to create a constant width for the strip-type material (11) over its longitudinal extension.

Description

technical field [0001] The invention relates to a vacuum coating plant according to the preamble of claim 1 and a method for coating a strip-shaped material according to the preamble of claim 6 . Background technique [0002] During the production of steel strips, a width change of the strip along the length occurs not only during hot rolling (Warmwalzen) but also during cold rolling (Kaltwalzen). This is caused by the so-called "broadening", which causes the width of the rolled strip to increase by a few millimeters through the rolling pass. The different spreads along the length of the steel strip are often attributed to traction force fluctuations within the plant for processing the steel strip. [0003] A further problem when rolling steel strips is that edge or center curls can occur due to the different lengthening of the cross-section due to the rolling process. [0004] When producing a strip material, for example in the form of a steel strip, it is known from the ...
