Patent number: 10870599Abstract: A flexible method of controlling the thickness of a material ribbon, in particular a glass ribbon, as well as an apparatus to implement such a method. To this end, a material in a heated and softened state is drawn into a ribbon and is then cooled down. During the forming process during which the ribbon is formed and drawn, the material is heated. During the forming process thermal energy at least partially in the form of thermal radiation that is emitted from a surface of a heated heating element. that is located opposite the material, is supplied to the material. Heating of heating element occurs at least partially through the energy of a laser beam that is directed onto heating element, thereby locally heating the heating element.Type: GrantFiled: May 22, 2018Date of Patent: December 22, 2020Assignee: Schott AGInventors: Frank Buellesfeld, Doris Moseler

Patent number: 10851009Abstract: A method for producing ceramizable green glass components provided, as well as apparatus for performing such method and ceramizable green glass components producible by such method. The method is a redrawing process in which a preform is heated, in a deformation zone, to a temperature that enables redrawing of the glass. The deformation zone is particularly small, which permits redrawing of the ceramizable green glass bodies while avoiding ceramization during the redrawing. The method provides plate-like or sheet-like green glass components that have a particularly smooth surface.Type: GrantFiled: October 29, 2015Date of Patent: December 1, 2020Assignee: SCHOTT AGInventors: Bernhard Hunzinger, Doris Moseler, Frank Büllesfeld, Ulrich Lange

Publication number: 20190263707Abstract: In a method for producing glass bottles having a flat base and an opposite filling opening, the base of the glass bottles is further formed at a plurality of processing positions. During the entire further forming of the base, with the aid of a purge gas which by way of the filling opening of the glass bottle flows in or out in a centric manner and flows out or in in an eccentric manner, a purge gas flow is generated in the interior of the glass bottle in order for delamination effects to be reduced. A tube or a nozzle serves for blowing in or suctioning out the purge gas. Various geometries and arrangements of the tube or of the nozzle are disclosed. A multiplicity of geometric constellations of the tube diameters and various mass flow settings are disclosed.Type: ApplicationFiled: May 15, 2019Publication date: August 29, 2019Applicant: Schott AGInventors: Robert Frost, Ulrich Lange, Doris Moseler
