  • Patent number: 10781036
    Abstract: 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.

  • Patent number: 9931816
    Abstract: A glass roll reliably prevents a glass film from breaking from an end surface of the glass film as an origin of breakage. The glass roll is formed by winding the glass film into a roll while superposing the glass film on a protective sheet. The glass film is formed by an overflow downdraw method to have a thickness of 1 ?m or more and 200 ?m or less, and has each end surface in a width direction formed as a cut surface cut by laser splitting.

  • Patent number: 9908806
    Abstract: A method of manufacturing a glass sheet involves forming a scribe in one surface of a glass sheet having a rectangular shape on a periphery of an edge portion of the glass sheet in parallel to the edge portion, and cutting the glass sheet along the scribe as a boundary. The method includes forming the scribe in a region other than both end portions of the glass sheet in a direction along the edge portion; and cutting the glass sheet along a bending portion in which the glass sheet is locally bent, the bending portion being continuously formed in a state of being connected to the scribe and gradually protruding from an edge portion side to an inner side as being shifted away from the scribe.
