  • Globular glass manufacturing apparatus and method for manufacturing the globular glass
    Patent number: 7587913
    Abstract: A globular glass manufacturing apparatus includes: a flow nozzle to flow a molten glass in a form of continuous flow, a collection tank to collect droplet-like glass gobs deformed from the molten glass flowing in a form of continuous flow during fall. Further, the globular glass manufacturing apparatus comprises a gas nozzle to shift one or both of falling trajectories of the glass gobs neighboring above and below by blowing gas to the glass gobs or sucking the glass gobs, wherein the gas nozzle rotates in which the center is on falling trajectory of the glass gobs.
