Apparatus for applying a liquid or viscid coating medium onto a moving fiber material web

1. Field of the Invention An apparatus applies a liquid or viscid coating medium onto a moving material web, especially one made of paper or cardboard. A coating mechanism first applies the coating medium onto an applicator element or an applicator roll, which subsequently transfers the coating medium at a coating location onto the material web in the form of a coating layer. Furthermore, if so desired, a doctoring device can be positioned at a doctor station, adjacent to the coating location, on the downstream side relative to the movement of the material web for the purpose of smoothing and/or metering the coating. The coating apparatus incorporates an apparatus for the generation and/or supplying of a fluid, preferably steam. This apparatus is positioned adjacent to the coating location or to the doctor station on the downstream side relative to the movement L of the material web.
