Abstract

Die Erfindung betrifft ein Auftragwerk und ein Verfahren zum direkten oder indirekten Auftragen eines flüssigen oder pastösen Mediums auf eine laufende Materialbahn. Das Auftragwerk umfaßt einen Tragbalken (2), der sich in seiner Längsrichtung im wesentlichen über die gesamte Breite der Materialbahn erstreckt, eine dem Tragbalken gegenüberliegende Gegenwalze (4), ein über eine Halteeinrichtung (8) an dem Tragbalken lösbar fixierte und sich im wesentlichen über die gesamte Breite der Gegenwalze erstreckendes Rakelelement (6), und ein an dem Tragbalken angeordnetes und direkt und/oder indirekt von einer Andrückeinrichtung (10) mit einer Andrückkraft beaufschlagtes Andrückelement, mit dem das Rakelelement im Bereich seines der Gegenwalze zugeordneten Rakelelementendes mit einem vorbestimmten Druck an die Gegenwalze andrückbar ist, wobei das Andrückelement bei Betrachtung im Querschnitt als ein Parallelogrammkörper (12) ausgebildet ist, der mit einem Ende in oder an wenigstens einer Halterung (14) gelagert ist und im wesentlichen parallel zu der Rakelklinge verläuft.

The invention relates to an applicator and a method for direct or indirect application of a liquid or pasty medium to a running material web. The applicator comprises a support beam (2) which extends in its longitudinal direction essentially over the entire width of the material web, a counter roller (4) opposite the support beam, a detachably fixed to the support beam via a holding device (8) and essentially over the entire width of the counter-roller extending doctor element (6), and a pressure element arranged on the support beam and directly and / or indirectly subjected to a pressing force by a pressing device (10), with which the doctor element in the area of its doctor element end associated with the counter-roller with a predetermined pressure can be pressed against the counter-roller, the pressing element, when viewed in cross-section, being designed as a parallelogram body (12) which has one end mounted in or on at least one holder (14) and extends essentially parallel to the doctor blade.
