Abstract (en)
[origin: US6285032B1] A device for removing the gaseous laminar boundary layer from at least one of the two sides of a material web moved in transport direction preferably at high speed, for example said web being made of paper, characterized by at least one corona-charging electrode provided with at least one elongate tip, and connectable to a positive (+U) or negative high-voltage source, and characterized by at least one counterelectrode associated with the latter and connectable to a negative (-U) or positive high voltage or ground, with corona-charging electrode on the side of material web having the boundary layer to be removed, and the associated counterelectrode being located on the other side.
