    摘要: Provided is a method of producing a glass roll including: a conveying step of conveying a glass film (G) along a longitudinal direction thereof; a cutting step of irradiating the glass film (G) with a laser beam (L) from a laser irradiation apparatus (19) while conveying the glass film (G) by the conveying step, to thereby separate the glass film (G) into a non-product portion (Gc) and a product portion (Gd); and a take-up step of taking up the product portion (Gd) into a roll shape, to thereby form a glass roll (R). The cutting step includes a step of winding a thread-like peeled material (Ge) generated from an end portion of the product portion (Gd) in a width direction around a rod-shaped collecting member (23), and leading the wound thread-like peeled material (Ge) in a predetermined conveying direction (PX) by a leading device (24).

    摘要: A method of manufacturing a glass includes a conveying step of moving a conveyance sheet material that contacts a lower surface of a glass film, to thereby convey the glass film. The conveyance sheet material includes a first contact portion that contacts the lower surface of the glass film on an upstream side in a manufacture-related process step, a second contact portion that contacts the lower surface of the glass film on a downstream side in the manufacture-related process step, and a non-contact portion that is prevented from contacting the lower surface of the glass film. In this method, the manufacture-related process step includes subjecting the glass film to a predetermined process at a position corresponding to the non-contact portion between the first and second contact portions while simultaneously moving the first, second, and non-contact portions of the conveyance sheet material through the conveying step.

    摘要: A glass roll (1) includes a laminate film (5) taken up into a roll shape, the laminate film including a glass film (2), a protective film (3), and an adhesive layer (4), which is arranged between the glass film (2) and the protective film (3), and is configured to bond the glass film (2) to the protective film (3). A width (A) of the protective film (3) is larger than a width (B) of the glass film (2), and both end portions (3x) of the protective film (3) in a width direction each protrude with respect to the glass film (2). The width (B) of the glass film (2) is larger than a width (C) of the adhesive layer (4), and both end portions (2x) of the glass film (2) in the width direction each protrude with respect to the adhesive layer (4).

    摘要: A manufacturing method for a glass roll includes cutting a glass ribbon along a longitudinal direction thereof in a cutting region on a conveyance path while conveying the glass ribbon, and taking up the cut glass ribbon around a roll core at a downstream end of the conveyance path. A conveyance-mode changeable region is provided between the cutting region and the downstream end of the conveyance path. The conveyance-mode changeable region enables a change in conveyance mode between a first mode of conveying the glass ribbon in a tensioned state and a second mode of conveying the glass ribbon in a loosened state. After the leading end portion of the glass ribbon is wound around the roll core in the first conveyance mode, the conveyance mode is shifted from the first conveyance mode to the second conveyance mode.

    摘要: A manufacturing method for a band-shaped glass film (GF) includes use of: a plurality of rollers (10) configured to change a direction of the falling band-shaped glass film (GF) to a horizontal direction; and a first horizontal-conveyance unit (4) configured to convey the band-shaped glass film (GF) in the horizontal direction after the changing of the direction of the band-shaped glass film (GF). After a lower end of the band-shaped glass film (GF) passes through a position between the plurality of rollers (10) being at a retreated position (P2) and the first horizontal-conveyance unit (4), the plurality of rollers (10) are moved from the retreated position (P2) to a regular position (P1) to apply a pressing force to the band-shaped glass film (GF), to thereby cut the band-shaped glass film (GF) along a width direction by bend-breaking.
