METHOD AND DEVICE FOR PROCESSING GLASS ELEMENTS

The aim of the invention is to separate glass elements more easily and reliably after hot working. A method for processing glass elements 1 is provided. The method includes introducing a perforation line 3 for parting a glass element 1 introduced into the glass element 1 during or after a hot processing process at an elevated temperature of at least 100deg C. Spaced-apart filamentary flaws 9 are introduced into the glass element 1 along the predetermined course of the perforation line 3 by a pulsed laser beam 5 of an ultrashort pulse laser 7, and, during or after the introduction of the filamentary flaws 9, the glass element 1 is cooled down so as to produce a temperature gradient, which induces a mechanical stress at the filamentary flaws 9, whereby the breaking force required for partingthe glass element 1 along the perforation line 3 is reduced. 本发明的目的是，在热加工之后更加简便又可靠地分离玻璃元件。为此，本发明提供一种处理玻璃元件(1)的方法，在该方法中在温度提高到至少100℃的热处理过程期间或之后，将用于分离玻璃元件(1)的穿孔线(3)引入到玻璃元件(1)中，通过借助超短脉冲激光器(7)的脉冲激光束(5)沿穿孔线(3)的预定路线将彼此间隔的丝状损伤(9)引入玻
