Zusammenfassung:Process for improvement of the surface quality of alkali-free float glass in which a hot glass strip is further transported by transport rollers where these contact the glass strip underside and after removal of sulfur dioxide and oxygen contact a water containing atmosphere containing at least 10 g H20 per Nm3. Es wird ein Verfahren zur Verbesserung der Oberflächenqualität von Alkali-freiem Floatglas beschrieben, bei dem zwecks Verringerung von Abdrücken oder Markierungen durch Transportwalzen die Unterseite des die Floatkammer verlassenden Glasbandes mit Schwefeldioxid oder -trioxid begast wird.
