  • Patent number: 10737967
    Abstract: A method is provided for separating a portion from a sheet-like glass or glass ceramic element along an intended separation line to divide the element into the portion and a main part. The method includes producing filamentary damages a volume of the glass or glass ceramic element adjacently aligned along the separation line, the filamentary damages are produced by laser pulses of a laser, the glass or glass ceramic element comprises a material that is transparent for the laser pulses; displacing incidence points of the laser pulses on a surface of the glass or glass ceramic element thereof along the separation line; and subjecting the material of the glass or glass ceramic element located in a region of the portion to a phase transition so that the material contracts to detach the portion from the main part at the adjacently aligned filamentary damages along the separation line, while the main part remains intact as a whole.

  • Patent number: 10501359
    Abstract: A method for controlling the thickness of a glass ribbon and an article produced thereby are provided. The method includes: providing a glass ribbon by drawing from a melt or redrawing from a preform; predefining a nominal thickness of the glass ribbon; determining the thickness of the glass ribbon over its entire net width; determining at least one deviation of the thickness of the glass ribbon from the predefined nominal thickness; identifying the area of the thickness deviation in the glass ribbon; and heating the area of the at least one thickness deviation in the glass ribbon using a laser, so that the glass ribbon attains the predefined thickness.

  • Patent number: 10023489
    Abstract: A method for producing, without a mold, a shaped glass article having a predefined geometry is provided. The method includes providing a starting glass, supporting the starting glass, heating a portion of the starting glass so that in the portion a predetermined spatial viscosity distribution of the starting glass is obtained from 109 to 104 dPa·s and so that at points where the starting glass is supported a predetermined spatial viscosity distribution of the starting glass does not fall below 1013 dPa·s, and deforming the heated starting glass by action of an external force until the predefined geometry of the glass article is obtained.

  • Publication number: 20160016841
    Abstract: A method for thermally treating an annular region of an inner surface of a glass container produced from a borosilicate glass tube is provided. The annular region is disposed at a tubular portion of the glass container and is disposed adjacent to a glass container bottom. The method includes: forming the glass container bottom from the glass tube; heating the annular region of the inner surface of the tubular portion to a treatment temperature TBeh above the transformation temperature TG, wherein the annular region is adjacent to the glass container bottom; maintaining the treatment temperature TBeh for a certain time period; and cooling the glass container to room temperature.
