| 20090314032 | Glass ribbon producing apparatus and process for producing the same - A glass ribbon producing apparatus ( | 12-24-2009 |
| 20100031702 | Glass ribbon producing apparatus and process for producing the same - Provided is a glass ribbon producing apparatus ( | 02-11-2010 |
| 20100122556 | PROCESS FOR PRODUCING GLASS SHEET AND GLASS SHEET PRODUCING EQUIPMENT - A situation where glass chip produced as a result of breakage of waste glass sheets floats in a cutting chamber when the waste glass sheets produced in glass sheet producing steps are collected is suppressed. Provided is a glass sheet production installation ( | 05-20-2010 |
| 20100269542 | PROCESS AND APPARATUS FOR PRODUCING GLASS SHEET - Provided is a process for producing a glass sheet including: a forming step of 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; an annealing step of removing an internal strain in the glass ribbon in an annealing furnace; a cooling step of cooling the glass ribbon to around room temperature; and a cutting step of 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. | 10-28-2010 |
| 20100281920 | PROCESS AND APPARATUS FOR PRODUCING GLASS SHEET - Provided is a process for producing a glass sheet including a forming step of 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; an annealing step of removing an internal strain in the glass ribbon in an annealing furnace; a cooling step of cooling the glass ribbon to around room temperature in a cooling chamber; and a cutting step of cutting the glass ribbon in a given size, in which the cooling chamber is provided with a gas exhausting passage, thereby exhausting air in the cooling chamber to an outside. | 11-11-2010 |
| 20110177347 | GLASS ROLL - Provided is a glass roll utilizing a flanged roll core, and reliably inhibiting a glass film from breaking from an end portion in a width direction thereof as an origin of breakage. A glass roll ( | 07-21-2011 |
| 20110200812 | GLASS ROLL AND PROCESS FOR PRODUCING GLASS ROLL - Provided is a glass roll formed by winding a glass film into a roll, in which a minimum winding radius of the glass film is optimized. Thus, the glass film is reliably prevented from breaking due to static fatigue, and is able to be stored for long periods. A glass roll ( | 08-18-2011 |
