摘要

Device for multi-layer coating of a moving paper-, board- or other fibrous web (2), comprises a first coating device (3) for applying a first coating layer or pre-coat (4) on a first side of the web, a second coating device (5) arranged downstream in the running direction of the fibrous web of the first coating device, for applying a second coating layer or a topcoat on the first side of the web, a supporting element (7) for moving the fibrous web, and a drying device arranged after the second coating device. The first coating device is a direct- or an indirect applying device. Device for multi-layer coating of a moving paper-, board- or other fibrous web (2), comprises a first coating device (3) for applying a first coating layer or a pre-coat (4) on a first side of the web, a second coating device (5) arranged downstream in the running direction of the fibrous web of the first coating device, for applying a second coating layer or a topcoat on the first side of the web, a supporting element (7) for moving the fibrous web, which partially loops around the supporting element, and a drying device arranged after the second coating device. The first coating device is a direct- or an indirect applying device, and the second coating device is a direct applying device that works in a contactless manner, where both the coating devices are associated with the same supporting element.
