Method for manufacturing glass film, and apparatus for manufacturing glass film

Abstract

To provide a glass film manufacturing method and glass film manufacturing equipment, each enabling suppression of sticking of glass powder to a glass film.SOLUTION: In a processing step of a glass film manufacturing method, a glass film G1 with an unnecessary portion is separated into a processing-object glass film G2 and an unnecessary glass film Ga including an unnecessary portion. In a carrying-out step of the glass film manufacturing method, a first carrying-out portion 20 and a second carrying-out portion 21 are used. The first carrying-out portion 20 has a moving mechanism which moves a first carrying-out sheet CS1 mounted with the processing-object glass film G2 along a first carrying-out path. The second carrying-out portion 21 has a moving mechanism which moves a second carrying-out sheet CS2 mounted with the processing-object glass film Ga along a second carrying-out path adjoining the first carrying-out path. A downstream end E1 of the first carrying-out path of the first carrying-out portion 20 extends to a more downstream side than a downstream end E2 of the second carrying-out path of the second carrying-out portion 21.SELECTED DRAWING: Figure 1
