Abstract: A glass roll of band-shaped glass film is free of skew and single slack when a roll-to-roll mode is used. The band-shaped glass film is wound into a roll shape and has creases formed thereon. The band-shaped glass film includes an effective section with two side edges in a width direction extending parallel to each other, and leading and trailing end portions extending parallel to the width direction. When a length from the leading end portion to the trailing end portion along a surface of the effective section is measured along each of a first position along one side edge and a second position along another side edge, a difference between the first and second measurement lengths is 400 ppm or less of a longer measurement length of the first and second measurement lengths.

Abstract: 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).

Abstract: 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.

Abstract: A method of manufacturing a glass film includes a forming step of forming a band-shaped glass film by pulling down a glass ribbon flowing down from a forming trough while sandwiching the glass ribbon from both front and back sides through use of roller pairs and a conveyance direction changing step of changing a conveyance direction of the glass film from the vertical direction to the horizontal direction by conveying the glass film along a conveyance path having an arc shape while supporting the glass film from a back surface side with a roller conveyor so that a front surface of the glass film after having passed through the conveyance path faces upward. A first roller to be brought into abutment against the glass film from the front surface side is arranged between a roller pair arranged in a lowermost stage and the roller conveyor.

Abstract: A method of manufacturing a glass roll includes separating unnecessary portions from a glass ribbon by cutting the glass ribbon along a longitudinal direction while conveying the glass ribbon. The method also includes passing the glass ribbon, from which the unnecessary portions are separated, through a looseness conveyance region on a conveyance path where the glass ribbon is loosened, and taking up the glass ribbon around a roll core at a downstream end of the conveyance path. A suction conveyor is provided between the looseness conveyance region and the downstream end on the conveyance path. While the glass ribbon is conveyed by the suction conveyor, the glass ribbon is tensioned between the suction conveyor and the downstream end on the conveyance path along with taking up the glass ribbon around the roll core.
