Abstract

Die erfindungsgemäße Vorrichtung (10) dient zum Auftragen eines flüssigen oder pastösen Auftragsmediums (14) auf einen laufenden Untergrund (U). Eine in einem Rakelbett (20) gelagerte Rakel (26) legt mit dem Untergrund (U) einen Dosierspalt (32) fest. Eine untergrund-einlaufseitige Begrenzungsfläche (20) des Rakelbetts (20) bildet mit dem Untergrund (U) einen entgegen der Laufrichtung (L) des Untergrunds (U) offenen und sich in Laufrichtung (L) des Untergrunds (U) stetig verjüngenden Stauraum (30), in welchem sich das vom Untergrund (U) mitgeführte Auftragsmedium (14) vor dem Dosierspalt (32) staut. Ferner ist eine Stellvorrichtung (28) vorgesehen zum Verändern der Relativlage der Begrenzungsfläche (20d) bezüglich des Untergrunds (U), d.h. zum Verändern der Gestalt des Stauraums (30).

Figure 00000001
The device (10) according to the invention is used to apply a liquid or pasty application medium (14) to a running surface (U). A doctor blade (26) mounted in a doctor bed (20) defines a metering gap (32) with the substrate (U). A boundary surface (20) of the doctor blade bed (20) on the underground inlet side forms, together with the underground (U), a storage space (30) which is open against the running direction (L) of the underground (U) and tapers continuously in the running direction (L) of the underground (U) ), in which the application medium (14) carried by the substrate (U) is stowed in front of the metering gap (32). An adjusting device (28) is also provided for changing the relative position of the boundary surface (20d) with respect to the subsurface (U), ie for changing the shape of the storage space (30).
