Zusammenfassung:	This invention relates to an improvement in a discharge and draw-off device for driers of material webs including nozzle casings mounted transversely over the path of a web to be dried, and having discharge apertures in said casings for discharging a drying medium and interstices between said casings for drawing-off said medium, the improvement comprising a substantially V-shaped formation of rows of the discharge apertures, whereby a double whirl is produced whose flow spiral increases in the direction toward the draw-off openings.
