Abstract
A method for producing a glass strip is provided. The method includes providing a glass preform with flat cross section, wherein the width of the cross section is at least five times greater than its thickness, wherein the cross section tapers into the edge regions in such a way that the thickness of the glass preform relative to its side edges amounts to at most two-thirds of the maximum thickness of a plate-shaped center region of the glass preform; heating the glass preform within a deformation zone, so that the glass found in the deformation zone softens; and applying a tensile force onto the glass preform in the direction perpendicular to the cross section, so that the glass preform is drawn in length in the deformation zone.
