  • Patent number: 11897806
    Abstract: An improved method and an improved apparatus are provided for producing a thin glass ribbon, which provide borders at the edges of the ribbon. The edges formed are of high mechanical quality and a formation of new secondary borders after the severing or at least the thickness of such secondary borders is reduced compared to the original borders. The method includes drawing the thin glass ribbon from a molten glass or from a preform, severing the borders, and cooling the resulting glass ribbon. The severing is effected at a location along the moving direction of the thin glass ribbon and at a time at which during the cooling of the thin glass ribbon the viscosity of the glass is in a range from 107 dPa·s to 1011 dPa·s, so that the edges of the thin glass ribbon newly produced by the severing of the borders are rounded off.

  • Patent number: 9662862
    Abstract: A glass substrate strip is provided includes a large number of thin-glass segments, which have been positioned and fixed on an adherent foil. The thin-glass segments have been fixed on the adherent foil by one of their entire area, their entire edge region, or their edge regions. The glass substrate strip can include lateral transport bands or coding fields. For storage, glass substrate strip is plated in undulating fashion or is rolled up, and it serves not only for transport and storage but also as carrier strip in processing steps for the thin-glass segments.
