  • Patent number: 9028940
    Abstract: A sheet roll comprises two glass films and a coupling portion, wherein end portions of the glass films are coupled together via the coupling portion and the coupled glass films are rolled into a roll shape. The coupling portion is a sheet-like coupling member formed of a resin film and placed on the end portions of the two glass films in a rolling direction so as to span therebetween. The sheet-like coupling member includes wide joint portions joined respectively to the end portions of the two glass films, and a necked portion which is narrower than the wide joint portions and is formed at a middle portion of the sheet-like coupling member in the rolling direction.

  • Patent number: 8769989
    Abstract: A cleaving apparatus holds at least one surface (effective surface) of a band-like glass film in a non-contact state to suppress a situation that wavy portions reach a region in which the band-like glass film is to be cleaved. The cleaving apparatus cleaves the band-like glass film, which is being conveyed in a longitudinal direction thereof, along a conveyance direction thereof using a thermal stress generated through localized heating and cooling of a heated region. The localized heating and the cooling is performed on a preset cleaving line extending along the conveyance direction of the band-like glass film. The cleaving apparatus includes an air knife for supplying air to a front surface of the band-like glass film to retain the film on a conveyor at a position on an upstream side of a cleaving region in the conveyance direction.

  • Publication number: 20120156439
    Abstract: A glass-resin laminate comprises an elongate glass film having a thickness of 1 to 300 ?m, and a peelable elongate resin film having a thickness of 1 to 300 ?m and a tensile modulus of elasticity of 0.3 Gpa or more. The elongate resin film is laminated on at least one surface of the elongate glass film so that the elongate resin film protrudes from edges on both sides in a lateral direction of the elongate glass film.

  • Publication number: 20120015132
    Abstract: A sheet roll (1) is manufactured by placing a sheet-like coupling member (3) on end portions of a plurality of glass films (g) so as to span therebetween, coupling the end portions of the glass films (g) together, and rolling the coupled plurality of glass films (g). The sheet-like coupling member (3) used in the sheet roll (1) includes wide width portions (4) for forming wide joint portions joined to the glass films (g) at each of both end portions thereof in a rolling direction, and a necked portion (5), which is narrower than the wide width portions (4) and is formed at a middle portion thereof in the rolling direction.

  • Publication number: 20110192878
    Abstract: A roll-to-roll apparatus reliably reduces breakage of a glass film even in a case of sequentially performing predetermined processing on the glass film. Provided is a glass roll (1) formed by winding a glass film (2) into a roll, in which a resin film (4) is attached onto the glass film (2), and at least a part of the resin film (4) is arranged on a front side of an unwinding direction relative to a leading end portion in the unwinding direction of the glass film (2).
