Patent number: 9382147Abstract: In an annealing zone (3) of a glass sheet producing method, a curved portion (5) is formed by curving a glass ribbon (G) in a width direction, and a concavo-convex direction in a front and back direction of the curved portion (5) is reversed at least between an upper side and a lower side of a part of a region in the width direction of the glass ribbon (G). Therefore, a bending resistance in an upper and lower direction of the glass ribbon (G) and a bending resistance in the width direction of the glass ribbon (G) are increased.Type: GrantFiled: June 18, 2015Date of Patent: July 5, 2016Assignee: NIPPON ELECTRIC GLASS CO., LTD.Inventors: Hidetaka Oda, Noritomo Nishiura, Koki Ueda, Tomonori Kano

Publication number: 20150266765Abstract: An apparatus for manufacturing a glass sheet has a pair of cooling rollers sandwich, from both front and back sides of a glass ribbon, each end portion of the glass ribbon in a width direction of the glass ribbon. The glass ribbon is produced by causing molten glass to flow down from a forming trough. A roller shaft of each of the pair of cooling rollers is arrayed so as to extend from a center side to each end side in the width direction of the glass ribbon. Each of the pair of cooling rollers catches the glass ribbon on an outer peripheral surface thereof, to thereby inhibit contraction in the width direction of the glass ribbon.Type: ApplicationFiled: June 2, 2015Publication date: September 24, 2015Inventors: Noritomo NISHIURA, Koji DOMORI, Yasuo YAMAZAKI, Kouki UEDA

Patent number: 8726695Abstract: A manufacturing apparatus for a thin glass sheet includes a forming member main body configured to form the thin glass sheet by fusing together, at a lower end portion of the forming member main body, streams of molten glass, which have overflown from an overflow trough to both sides of the forming member main body, under a state in which the streams of the molten glass are caused to flow down along outer surface portions having a substantially wedge shape. The manufacturing apparatus also includes a pair of covering members fitted onto both widthwise end portions of the forming member main body, respectively, the pair of covering members forming restricting wall portions for restricting widthwise spread of the streams of the molten glass flowing down along the outer surface portions of the forming member main body.Type: GrantFiled: March 26, 2012Date of Patent: May 20, 2014Assignee: Nippon Electric Glass Co., Ltd.Inventors: Tomonori Kano, Noritomo Nishiura, Koki Ueda, Takahide Nakamura, Daisuke Nagata, Hidetaka Oda, Yuji Iwama

Patent number: 8322160Abstract: A process produces a glass sheet. The process includes down-drawing a molten glass into a sheet-like glass ribbon, in which the molten glass is fed to a forming trough arranged in a forming furnace and the molten glass is caused to flow down from the forming trough through a conveyance passage extending vertically. The process also includes removing an internal strain in the glass ribbon in an annealing furnace, cooling the glass ribbon to around room temperature, and cutting the glass ribbon in a given size, in which a pressure in an outside atmosphere of the forming furnace and/or the annealing furnace is elevated.Type: GrantFiled: December 10, 2008Date of Patent: December 4, 2012Assignee: Nippon Electric Glass Co., Ltd.Inventors: Noritomo Nishiura, Koki Ueda, Hidetaka Oda, Tomonori Kano, Daisuke Nagata
