APPLICATION DEVICE

摘要

The invention relates to a device (510) which disposes of an application mechanism (512) that directly or indirectly applies a liquid or pasty application medium (516) to a material web (520) made of, in particular, paper or paperboard. The inventive device comprises an element (570), which is arranged before the application mechanism (512) in the direction of movement (L) of the substrate (U) and which is provided for attenuating the air boundary layer (G) carried along by the substrate (U). To this end, the attenuating device can comprise a sealing element (570) which is pressed in a sealing manner against the substrate (U) and which rolls off the same with essentially no slippage, and/or the inventive device can comprise an electrode configuration and/or an ultrasound source and/or an elastic masking element that functions in a contactless manner.
