Abstract: An applicator head for a curtain applicator for coating a continuous material web with liquid or pasty application medium. The applicator head has an outlet edge extending substantially over the width of the applicator head. The application medium passes out of the applicator head in a free-falling curtain. A rinsing device allows the outlet edge to be supplied with a flowing gaseous rinsing medium. There is also described a method for coating a continuous material web by way of such a curtain applicator. The application medium passes out of the applicator head in the form of a free-falling curtain and subsequently comes into contact with the material web. The region of at least one of the outlet edges can be supplied with a flowing gaseous rinsing medium.

Abstract: A curtain applicator for applying a liquid or pasty application medium to at least one surface of a running material web, in particular a fibrous web. The curtain applicator has an applicator nozzle, in particular a slotted nozzle, which under the effect of gravity, and optionally with further forces, is suitable for dispensing a single-tier or multi-tier curtain onto the surface of the material web. The curtain applicator further has a wiping device which is suitable for keeping entrained air carried by the material web away from the curtain. Moreover, there is provided at least one further blocking device which is suitable for keeping air movements of the ambient air away from the curtain.
