Abstract

Die Erfindung betrifft eine Vorrichtung (1) zum Auftragen eines flüssigen oder pastösen Auftragsmediums (2) auf einen laufenden Untergrund (3), wobei der Untergrund (3) bei direktem Auftrag die Oberfläche einer Papier-, Karton- oder anderen Faserstoffbahn ist oder bei indirektem Auftrag die Oberfläche eines Übertragungselements, beispielsweise einer Übertragungswalze, ist, welches das Auftragsmedium (2) an die Faserstoffbahn überträgt, wobei das Auftragsmedium (2) in einer Auftragskammer (8) auf den laufenden Untergrund (3) auftragbar ist und die Auftragskammer (8) in Laufrichtung (L) des Untergrunds (3) betrachtet einlaufseitig von einer Dichtrakelvorrichtung (9) und auslaufseitig von einer Dosierrakelvorrichtung (10), die jeweils mit einem Rakelstab (11, 12) versehen sind, begrenzt ist. Bei denen aus dem Stand der Technik bekannten gattungsgemäßen Vorrichtungen sammeln sich in der Auftragskammer (8) Verunreinigungen an, die bei der Auftragsschicht (4) zu Qualitätseinbußen führen. Die Erfindung hat die Aufgabe, die Qualitätseinbußen zu reduzieren. Deshalb weist der Rakelstab (12) der Dosierrakelvorrichtung (10) erfindungsgemäß eine höhere Durchlassfähigkeit auf, als der Rakelstab (11) der Dichtrakelvorrichtung (9).

The invention relates to a device (1) for applying a liquid or pasty application medium (2) on a running substrate (3), wherein the substrate (3) is the surface of a paper, board or other fibrous web or direct indirect application Order is the surface of a transmission element, such as a transfer roller, which transfers the application medium (2) to the fibrous web, the application medium (2) in an application chamber (8) on the running surface (3) can be applied and the application chamber (8) viewed in the direction of travel (L) of the substrate (3) on the inlet side of a sealing doctor device (9) and the outlet side of a Dosierrakelvorrichtung (10), which are each provided with a metering rod (11, 12) is limited. In those known from the prior art generic devices accumulate in the application chamber (8) impurities that lead to quality loss in the application layer (4). The invention has the task of reducing the quality losses. Therefore, according to the invention, the metering rod (12) of the metering doctor device (10) has a higher permeability than the metering rod (11) of the sealing doctor device (9).
