Abstract

Die Erfindung betrifft eine Vorrichtung (1) zum ein- oder beidseitigen Auftragen von flüssigem bis pastösem Auftragsmedium, auf eine laufende Oberfläche (7), die bei direktem Auftrag die Oberfläche einer Materialbahn, insbesondere aus Papier- oder Karton und bei indirektem Auftrag die Oberfläche eines Übertragselementes ist, welches das Auftragsmedium dann an die Materialbahn abgibt. In einem in einem bestimmten Abstand (HC) ist zur laufenden Oberfläche (7) ein Vorhang-Auftragskopf (2), enthaltend eine Auftragsdüse (4) angeordnet, welche das Auftragsmedium als sich im Wesentlichen schwerkraftbedingt bewegenden, frei fallenden Vorhang (5) in einer Betriebsposition (I) abgibt. Außerdem ist ein wannenartiger Vorhangauffänger (8) vorhanden, der in einem Abstand (HW) seiner Oberkante zur laufenden Oberfläche (7) angeordnet ist und der in der Start- und/oder Stopp-Phase des Vorhangauftrages sowie bei Betriebsunterbrechungen den Vorhang (5) in einer Auffangposition (II) auffängt.The invention relates to a device (1) for one or two-sided application of liquid to pasty application medium, on a running surface (7), the direct surface of a web of material, in particular paper or cardboard and indirect application, the surface of a Transfer element is, which then dispenses the application medium to the web. In a at a certain distance (H C ) to the running surface (7) a curtain applicator head (2) containing an applicator nozzle (4) is arranged, which the application medium as substantially gravity-related moving, free-falling curtain (5) an operating position (I) outputs. In addition, a trough-like curtain catcher (8) is present, which is arranged at a distance (H W ) of its upper edge to the running surface (7) and in the start and / or stop phase of the curtain application and during interruptions in operation, the curtain (5). in a collecting position (II).

Erfindungsgemäß ist vorgesehen, dass der Auftragskopf (2) mit Vorhangdüse (4) derart drehbar und/oder linear verschiebbar ist, dass der Vorhangauffänger (8') den im gedrehten und/oder verschobenen Zustand der Vorhangdüse (4) abgegebenen Vorhang (5) aufnimmt, wobei der Abstand (HC) geringer als der Abstand (HW) ist.

Figure imgaf001
According to the invention, it is provided that the application head (2) with the curtain nozzle (4) is rotatable and / or linearly displaceable such that the curtain catcher (8 ') receives the curtain (5) delivered in the rotated and / or displaced state of the curtain nozzle (4) , wherein the distance (H C ) is less than the distance (H W ).
