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.

Abstract: A glass ribbon in the form of a glass roll is provided that is optimized with respect to the requirements of a long service life and at the same time compact dimensions. A bending radius on the inner side of the thin glass roll is determined by performing breakage tests on samples of the glass material, statistical parameters are determined on the basis of the breakage tests, and the statistical parameters are converted into a range of bending radii which meet the requirements on service life and the most compact dimensions possible of the thin glass roll.

Abstract: A method for separating a thin glass, in which method the thin glass is progressively heated along a path which forms a parting line, wherein the heating of the glass is realized by way of the energy of at least one energy source within an area of action of the energy source on the thin glass, and, by way of a temperature gradient of the glass heated by way of the at least one energy source in relation to the surrounding glass, a mechanical stress is generated in the glass, by way of which mechanical stress, a crack propagates, following the mechanical stress, along the parting line.

Abstract: A glass roll includes at least one glass film and one intermediate material one on top of the other in at least two layers onto a winding core. The glass film layers are held in place by the intermediate material layers. The glass roll is produced with a method including provision of a glass film, a winding core and a compressible intermediate material. At least one inside layer of the intermediate material is wound onto the winding core. The glass film and the intermediate material are wound onto the winding core in such a manner that the glass film is wound onto the winding core in alternating layers with the intermediate material. The intermediate material and/or the glass film is wound at a tensile stress acting in a longitudinal direction which causes a compression of the intermediate material and holds the glass film end in place on the glass roll.

Abstract: A method for winding up a glass ribbon is provided, in which, prior to winding up the glass ribbon, the two surfaces of the glass ribbon are each initially treated with a water-containing medium and subsequently dried so as to produce a defined content of water molecules on the two surfaces, by achieving a saturation of the surfaces of the glass ribbon with water, without bringing about an excess of water molecules. A glass roll is produced in which the electrostatic charge of the glass surface is reduced and, as a result, any undesired excess adherence of the glass surface to an interleaf material is prevented and, in this way, glass breakage, in particular during winding up and/or unwinding of the glass roll, can be markedly reduced.
