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

An apparatus for applying a coating medium onto a moving fiber material web having a direction of movement, said apparatus comprising:

• an applicator element configured for transferring a coating layer of the coating medium onto the fiber web at a coating location, said applicator element being configured for jointly defining a coating sump with said fiber web immediately before said coating location relative to the direction of movement of the fiber web;
• a coating mechanism associated with said applicator element, said coating mechanism configured for applying the medium onto said applicator;
• a steam device configured for at least one of generating and supplying steam, said steam device being disposed adjacent to and after of said coating location relative to the direction of movement of the fiber web;
• and
• a suction apparatus disposed on a side of said steam device substantially opposite said coating location, said suction apparatus being configured for at least one of:
• evacuating at least one of a fluid-saturated atmosphere and droplets and particles of the coating medium that do not adhere to the fiber web;
• and
• collecting said droplets and said particles of the coating medium that do not adhere to the layer of coating medium.
