摘要： A method of manufacturing a glass roll, includes: a forming step (S1) of forming, while conveying a glass film, the glass film by a downdraw method; a temporary rolling step (S3) of rolling the glass film while superposing a protective film on the glass film at a downstream end of a path of the conveying in the forming step (S1), to thereby manufacture a source glass roll; and a main rolling step (S4) of unrolling, while conveying the glass film to a downstream side, the glass film from the source glass roll, and then rerolling the glass film while superposing a protective film on the glass film at a downstream end of a path of the conveying, to thereby manufacture a glass roll. Higher tension in a rolling direction is applied to the glass film in the main rolling step (S4) than in the temporary rolling step (S3).

摘要： Provided is a glass roll (1), including: a winding core (2); a film body (F), which is taken up into a roll shape by the winding core (2), and includes a glass film (3) and a scattering prevention film (7) having a smaller width than the glass film (3); and flanges (8) which are mounted to the winding core (2), and which are arranged on both sides of the film body (F) in a width direction. The film body (F) includes a detachable displacement prevention film (6) on a termination end portion side of the glass film (3) in a take-up direction. The displacement prevention film (6) includes a wide portion (6a) having a lager width than the glass film (3).

摘要： 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).

摘要： Provided is a method of manufacturing a glass sheet including a step of bringing a glass sheet (G1, G2) having a first liquid adhering to a surface into contact with a roller (5a, 5b). The glass sheet (G1, G2) includes: a first glass sheet (G1); and a second glass sheet (G2) having a contact length with the roller (5a, 5b) which is larger than that of the first glass sheet (G1). The step of bringing the glass sheet (G1, G2) into contact with the roller (5a, 5b) includes a liquid supplying step of, at the time of bringing the first glass sheet (G1) into contact with the roller (5a, 5b), applying a second liquid to a non-contact portion of the roller (5a, 5b) which is prevented from being brought into contact with the first glass sheet (G1).

摘要： Provided is method of producing a glass roll, the method 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 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 (20a), to thereby collect the thread-like peeled material (Ge).
