Publication number: 20200369551Abstract: A method for processing glass elements is provided. The method includes introducing a perforation line for parting a glass element introduced into the glass element during or after a hot processing process at an elevated temperature of at least 100° C. Spaced-apart filamentary flaws are introduced into the glass element along the predetermined course of the perforation line by a pulsed laser beam of an ultrashort pulse laser, and, during or after the introduction of the filamentary flaws, the glass element is cooled down so as to produce a temperature gradient, which induces a mechanical stress at the filamentary flaws, whereby the breaking force required for parting the glass element along the perforation line is reduced.Type: ApplicationFiled: May 22, 2020Publication date: November 26, 2020Applicant: SCHOTT AGInventors: Andreas Ortner, Ulla Trinks, Fabian Wagner, Carsten Etz, Daniela Seiler, Michael Kluge, Peter Czepelka, Frank-Thomas Lentes, André Witzmann, Reiner Artmann

Publication number: 20040129024Abstract: The invention relates to a method and a device for reducing the adhesion tendency during the hot forming of a glass body, using at least two moulds, which are positioned on either side of the glass body and are brought into contact with the glass body at a temperature, at which the glass is deformable, whereby the moulds are configured with electrically conductive surfaces. The disadvantage of existing methods and devices is that the moulds have a tendency to adhere to the glass body to be formed and that the surface quality of the glass is impaired. The invention therefore discloses a method, according to which the conductive surfaces of the moulds that come into contact with the glass body are supplied with an alternating current. The device for carrying out said method has electrically conductive mould surfaces, which are connected to an alternating current source. This guarantees that a larger processing window is available as a result of the reduced adhesion tendency, i.e.Type: ApplicationFiled: October 7, 2003Publication date: July 8, 2004Inventors: Ulrike Stoehr, Olaf Claussen, Daniela Seiler, Sylvia Biedenbender, Gernot Roeth, Ralf-Dieter Werner
