Abstract
A method for producing a flat thin glass ribbon is provided. The method includes the steps of drawing melted glass downward away from a tank in a pulling direction while applying tensile forces which act in the pulling direction to form the thin glass ribbon having a thickness of at most 250 μm and cooling the thin glass ribbon until a temperature of the thin glass ribbon undershoots a glass transition temperature. The tensile forces are transferred to the thin glass ribbon by at least two pairs of drawing rollers. The at least two pairs of drawing rollers are spaced apart transversely to the pulling direction and contact the thin glass ribbon on longitudinal edges of the thin glass ribbon. The thin glass ribbon only makes contact with the at least two pairs of drawing rollers at a position where the temperature of the thin glass ribbon is at most at or below 500° C.
