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： 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).

摘要： A conveying device (14) for a glass film (G) includes: a first support (21) configured to support a first portion (Gc) of the glass film (G) having been cut; a second support (22) configured to support a second portion (Gd) of the glass film (G) having been cut; and an opening (23) formed at a position between the first support (21) and the second support (22) and below a laser irradiation apparatus (19). A cutting step for the glass film (G) includes deforming the glass film (G) so as to be convex downward through the opening (23), and radiating a laser beam (LB) from the laser irradiation apparatus (19) to a position which is within a range of the opening (23), and which is prevented from coinciding with a top (GT) of the glass film (G).
