Abstract
Examples include a device for coating a carrier substrate with a powdered material. The device includes an application unit having a first roller and a second roller which, at a nip thereof, form a first gap through which a powder mixture can be conveyed to form a dry film. A counter-pressure roller, together with the second roller or another roller arranged between the counter-pressure roller and the second roller, forms a second gap through which the carrier substrate to be coated can be guided for having the dry film applied to the carrier substrate. The first gap between the first and second rollers can be adjusted based on a position-based positioning drive by being set to a constant and/or defined gap width, and the second gap can be adjusted based on a force-based positioning drive, and can be set to a constant and/or defined contact force or linear force.
