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.
