    Abstract: A device (10) for the direct or indirect application of liquid or pasty application medium (16) to one or both sides of a material web (20), in particular of paper or board, comprises an applicator unit (12) which discharges the application medium (16) onto the material web (20) in the form of a free application medium jet (18). In this case, in the region of the applicator unit (12) there is provided a device (30) for producing an electric field, which exerts on the application medium jet (18) moving from the applicator unit (12) to the material web (20) a force which assists its movement. Additionally or alternatively, edge guiding elements can be provided, which guide the lateral edges of the application medium curtain (18) at least on part of its movement under the force of gravity.

    Abstract: A device (510) for the direct or indirect application of liquid or pasty application medium (516) by means of an applicator unit (512) to a material web (520), in particular of paper or board, comprises a device (570) upstream of the applicator unit (512) in the running direction (L) of the substrate (U) in order to attenuate the air boundary layer (G) carried along by the substrate (U). The attenuation device can in this case comprise a sealing element (570) which is pressed in a sealing manner against the substrate (U) and rolls on the latter substantially without slippage, and/or can comprise an electrode arrangement and/or can comprise an ultrasound source and/or can comprise a resilient diaphragm element acting without contact.

    Abstract translation: 用于通过施用器单元(512)将液体或糊状施用介质(516)直接或间接施加到材料网(520),特别是纸或板的装置(510)包括装置(570) 为了衰减由基板(U)携带的空气边界层(G),在基板(U)的运行方向(L)上的施加单元(512)的上游。 在这种情况下,衰减装置可以包括密封元件(570),该密封元件(570)以密封方式压靠在基底(U)上并且基本上不会滑动地在其上滚动,和/或可以包括电极装置和/或可以包括 超声波源和/或可以包括不接触地作用的弹性隔膜元件。
