摘要： An apparatus is provided that heats the glass of a primary glass product to be formed. The apparatus includes a laser that emits light at a wavelength for which the glass of the primary glass product is at most partly transparent, such that the light is absorbed at least partially in the glass. The apparatus also includes a mold having a forming mandrel having a thermally stable ceramic material, at least in the region that forms the contact surface with the glass during the forming process.

摘要： 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.

摘要： 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.
