  • Method and apparatus for continuously cutting glass
    Patent number: 10407336
    Abstract: A method for cutting a thin glass including the steps of guiding, by a transport device, the thin glass ribbon over a levitation support, and directing, within a range of the levitation support, a laser beam onto the thin glass ribbon, which heats up the thin glass ribbon at an impingement point of the laser beam. The method also includes the step of blowing, by a cooling jet generator, a cooling fluid onto the track heated by the laser beam so that a region heated by the laser beam is cooled down and a mechanical stress is created. The cooling fluid contains vapor of a liquid at a saturation ratio of at least 0.5 or a plurality of liquid droplets. The liquid droplets form a contact angle on a surface of the thin glass ribbon which is smaller than that of water on the same surface.

  • METHOD FOR PRODUCING GLASS BOTTLES WITH A LOW DELAMINATION TENDENCY UNDER THE EFFECT OF A PURGE GAS FLOW
    Publication number: 20190263707
    Abstract: 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.

  • Apparatus and method for producing glass products from a glass melt while avoiding bubble formation
    Patent number: 10358371
    Abstract: An apparatus and a method for producing glass products from a glass melt, avoiding bubble formation, are disclosed, wherein the apparatus includes a crucible and an internally component for processing the glass melt, and wherein, for heating the glass melt, the apparatus comprises an AC generator which energizes the crucible or stirring crucible via electrical connection elements. The component or stirring system is connected via a current-limiting choke having a variable impedance with the power supply elements. The impedance of the current-limiting choke is adjusted so that a AC density existing in the glass melt lies between a lower limit value and an upper limit value. By means of a choke and by adjusting the impedance it can be achieved that the AC load of the system can be minimized and that simultaneously the water decomposition reaction at the precious metal surfaces can positively be influenced.
