Device and method for coating of a metallic strip substrate on one side and/or on both sides

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.
