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 method of manufacturing a glass film, including: a conveying step of conveying an elongated glass film (G) along a longitudinal direction thereof; and 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) through the conveying step, to thereby separate the glass film (G). The cutting step includes generating a thread-like peeled material (Ge) in a helical shape from an end portion of the separated glass film (G) in a width direction. The thread-like peeled material (Ge) has a width (W) of 180 μm or more and 300 μm or less. In addition, the thread-like peeled material (Ge) has a helical diameter (D) of 80 mm or more and 200 mm or less.

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.

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).
