Publication number: 20200290913Abstract: A method for removing bubbles from molten glass is provided and involves subjecting the surface of the molten glass to at least one fining sequence wherein the fining sequence comprises subjecting the surface of the molten glass to a sub-atmospheric pressure (relative vacuum less one atmosphere of pressure) for a time followed by subjecting the surface of the molten glass to super-atmospheric gas pressure (greater than one atmosphere of pressure) for additional time. The fining sequence can be repeated as needed to produce a high quality optically clear glass that is substantially free of bubbles.Type: ApplicationFiled: March 10, 2020Publication date: September 17, 2020Inventors: Steve w.

Publication number: 20200290915Abstract: A method of manufacturing glass ribbon can comprise feeding molten material through a minimum width of a first gap defined between a first roller and a second roller of a first pair of rollers. A first pool of molten material can be formed upstream from the minimum width of the first gap. A ribbon of molten material can exit the first gap. The methods can further include passing the ribbon of molten material through a minimum width of a second gap defined between a first roller and a second roller of a second pair of rollers. The minimum width of the first gap can be greater than the minimum width of the second gap. A second pool of molten material can be formed upstream from the minimum width of the second gap.Type: ApplicationFiled: October 30, 2018Publication date: September 17, 2020Inventors: Antoine Gaston Denis Bisson, Daniel Rousseau

Publication number: 20200290916Abstract: Systems, apparatuses and methods for processing a glass ribbon (22). A glass ribbon is supplied to an upstream side of a conveying apparatus (32). A pulling force is applied on the glass ribbon (22) at a downstream side of the conveying apparatus (32). The glass ribbon (22) is supported at first and second support devices along a travel path of the conveying apparatus (32). Each of the first and second support devices (72) establishes a non-rolling, line-type interface with the glass ribbon (22). Further, the first support device (72a) is spaced from the second support device (72c) along the travel path. In some embodiments, the line-type interface comprises a sliding interface or a gas bearing interface.Type: ApplicationFiled: October 30, 2018Publication date: September 17, 2020Inventor: Antoine Gaston Denis Bisson
