摘要： Process and device for acting on one of a still-wet and moist material web with one of a fluid and pasty coating medium in the manufacturing process. The process includes producing the material web in a wet section of a web producing machine, applying, in at least one coating point, a coating medium to at least one surface of the material web while the material web is in the wet section, and applying at least one of steam and water in the region of the at least one coating point. The device includes at least one endless, water-permeable belt, at least one coating device being adapted for one of direct and indirect application of a fluid or pasty coating medium onto at least one side of a still-wet material web, and at least one applicator device, positioned in a region in which the coating medium contacts at least one of the material web and at least one belt, being adapted to condition the at least one of the material web and the at least one belt with at least one of steam and water.
