  • Patent number: 11090905
    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.

  • Publication number: 20140284236
    Abstract: A packaging unit for accommodating glass rolled onto a winding core is provided. The packaging unit includes at least two wall parts that can be separated from one another and together form a closed unit. A first retaining element is connected to a first wall part and a second retaining element is connected to a second wall part arranged opposite the first wall part. A damping element is connected to at least one retaining element and/or to at least one of the first and second wall parts.

  • Publication number: 20140216108
    Abstract: A method for separating a thin glass sheet, such as a glass film along a predefined cutting line provides the cutting line immediately has a temperature of greater than 250 K below the transformation point Tg of the glass of the thin sheet of glass, including the input of energy along the cutting line using a laser beam which acts such that a separation of the thin glass sheet occurs.

  • Publication number: 20140220310
    Abstract: A glass film has a thickness of less than 1.2 mm, and a first and a second surface, both surfaces being defined by edges having an edge surface. The respective edge surfaces are provided with a microstructure surface, including micro-cracks and fissures which are laterally defined by flanks. At least two edges located opposite one another include a low viscosity adhesive having a viscosity of less than 600 mPas at 23° C., on their microstructure surfaces in such a way that the respective flanks of the micro-cracks and fissures are bonded together using an adhesive so that the probability of failure of the glass film having a length of 1000 m and a thickness in the range of 5 ?m to 350 ?m, and a diameter of a wound glass film roll in the range of 50 mm to 1000 mm is less than 1%.
