Title: Device for direct or indirect application of liquid or viscous coating medium onto a moving material web

Abstract: A device for direct or indirect application of a liquid or viscous coating medium onto a moving material web, specifically a paper or cardboard web, includes an applicator unit which, in the direct application method, applies the coating medium in the form of a coating layer directly onto the material web at a point of application. In the indirect application method, the coating medium is first applied onto an applicator element, for example an applicator roll, which then transfers, at the point of application, the coating medium to the material web in the form of a coating layer. In addition, a drying device for drying of the coating layer is provided downstream from the point of application, viewed in the direction of flow of the material web. In the applicator unit, a device for moistening and/or warming the material web, coating medium or the coating layer is additionally provided before the drying device, viewed in the flow direction of the material web.
