Abstract

An apparatus is provided for drawing glass ribbons from molten glass. The apparatus includes a drawing tank for holding the molten glass and a guiding body. The tank has a lower nozzle opening through which the molten glass can exit downwards. The nozzle opening has two nozzle slots defined between the guiding body and edges of the nozzle opening. The guiding body protrudes downward out of the nozzle opening. The guiding body is supported so as to be spaced apart from the edges with the guiding body suspended in a self-supporting manner at least along a central section of the nozzle opening.
