Abstract:
A method for one of direct and indirect application of a coating medium onto a traveling fiber material web having a width, the coating medium having a flow direction, said method comprising the steps of:providing an applicator including at least one metering system having an approach-side lip and a departure-side lip defining a metering slot therebetween, one of said approach-side lip and said departure-side lip being movable in at least one direction substantially parallel to the flow direction of the coating medium, said metering slot being configured as an open-jet nozzle for issuing the coating medium as an open jet;attaching at least one monolithic guide surface having a length to said metering system, said monolithic guide surface having at least one curve with a radius of curvature and an angle of curvature, said at least one guide surface being disposed opposite said one movable lip;varying at least one of said radius of curvature and said angle of curvature of said at least one curve of said monolithic guide surface;passing said issuing open jet of the coating medium along said at least one guide surface, thereby applying the coating medium onto the fiber web; andadjusting said length of said guide surface in at least one direction substantially parallel to the flow direction of the coating medium along said guide surface.
