A film application mechanism applies a pasty or fluid coating medium to a running fibrous material web, particularly a paper or cardboard web. At least one roller of a roller pair is an application roller, for transferring the coating medium provided in the form of a film on the application roller to one side of the fibrous material web. An application device and a doctor blade element are associated with the application roller such that the coating material is first applied in excess to the application roller upstream of the first nip by the application device and then removed in part in a second nip by the doctor blade element which forms the second film-forming nip with the application roller. Pressure sensors for determining a pressure profile transversely to the machine direction in the first and second nips are embedded in the elastic covering of the application roller. |
