Method for manufacturing glass roll

A method of producing a glass roll, the method comprising:

• a conveying step of conveying a glass film
• along a longitudinal direction thereof;
• a cutting step of irradiating the glass film with a laser beam from a laser irradiation apparatus while conveying the glass film by the conveying step, to thereby separate the glass film into a non-product portion and a product portion;
• and
• a take-up step of taking up the product portion into a roll shape, to thereby form a glass roll,
• wherein the cutting step comprises a step of winding a thread-shaped peeled material generated from an end portion of the product portion in a width direction around a rod-shaped collecting member, and leading the wound thread-shaped peeled material in a predetermined conveying direction by a leading device, and
• wherein the rod-shaped collecting member comprises:
• a first guiding portion extending in a lateral direction;
• a second guiding portion located on a downstream side of the first guiding portion in the predetermined conveying direction and angled downward toward the downstream side in the predetermined conveying direction;
• and
• a third guiding portion extending downward and being located on a downstream side of the second guiding portion in the predetermined conveying direction.
