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 |
20130091897 | GLASS SHEET CUTTING METHOD - A glass sheet cutting device ( | 04-18-2013 |
20130122264 | Cutting method for glass sheet and glass sheet cutting apparatus - Provided is a cutting method for a glass sheet, comprising radiating a laser beam to a cutting portion (C) of a glass sheet (G) having a thickness of 500 μm or less to fuse the glass sheet (G), wherein a narrowest gap between fused end surfaces (Ga1 and Gb1) of the glass sheet (G), which face each other in the cutting portion (C), is managed to satisfy a relationship of 0.1≦b/a≦2, where “a” is a thickness of the glass sheet (G) and “b” is the narrowest gap. | 05-16-2013 |
20130167590 | Method of cleaving and separating a glass sheet and apparatus for cleaving and separating a glass sheet - Provided is a method of cleaving and separating a glass sheet, the method comprising: a cleaving step of cleaving a glass sheet (G) along preset cleaving lines (X, Y) by a laser cleaving method; and a separation step of separating adjacent pieces of the cleaved glass sheet (G) from each other, wherein the cleaving step is performed under a state in which the glass sheet (G) is placed on support members ( | 07-04-2013 |
20130174610 | METHOD OF CLEAVING AND SEPARATING A GLASS SHEET - Provided is a method of cleaving and separating a glass sheet (G), the method comprising: a cleaving step of cleaving the glass sheet (G) along preset cleaving lines (X, Y) by a laser cleaving method; and a separation step of separating adjacent pieces of the cleaved glass sheet (G) from each other, wherein the cleaving step is performed under a state in which the glass sheet (G) is placed on a sheet (S) having stretchability, and the separation step is performed by stretching the sheet (S). | 07-11-2013 |
20140319001 | GLASS ROLL WITH A SEPARABLE PROTECTIVE SHEET - A glass roll includes a glass film formed by a downdraw method. The glass film is wound into a roll using a winding roller in a state in which front and back glass surfaces of the glass film formed in the forming operation are exposed, and during the winding operation, the glass film is superposed on a separable protective sheet. The protective sheet extends beyond both sides in a width direction of the glass film. The protective sheet can further be wound on an outer peripheral surface of the glass film by winding only the protective sheet from a trailing end of the glass film in a winding direction of the glass film. | 10-30-2014 |
20150210585 | SHEET GLASS, METHOD FOR MANUFACTURING SHEET GLASS, AND DEVICE FOR MANUFACTURING SHEET GLASS - Provided is a method of manufacturing a glass sheet, which involves forming a scribe (S) in one surface of a glass sheet (G) having a rectangular shape on a periphery of an edge portion (Ga) of the glass sheet (G) in parallel to the edge portion (Ga), and cutting the glass sheet (G) along the scribe (S) as a boundary, the method including: forming the scribe (S) in a region other than both end portions of the glass sheet (G) in a direction along the edge portion (Ga); and cutting the glass sheet (G) so that a maximum stress is generated at a corner portion (Gb) of the glass sheet (G) in a region on an inner side of an imaginary extension straight line connected to the scribe (S). | 07-30-2015 |
