Abstract: The invention relates to a method for producing thin glass panes, especially glass panes with a thickness of below 1 mm, by drawing a thin glass strand vertically downwards. According to the inventive method, a glass melt is fed from a melting bath via a feed to the glass drawing tank that comprises a nozzle system with at least one slotted nozzle. The length and the diameter of the feed as well as the viscosity of the glass melt present in the feed determine the overall throughput. The throughput per length unit in the transverse direction to the glass strand (so-called line throughput) is adjusted via the geometry of the nozzle system and via the viscosity of the glass melt present in the nozzle system. These parameters are adjusted in such a manner that the glass, when leaving the nozzle system, does not wet the bottom of the slotted nozzle in the range of the tearoff edge.
