  • Publication number: 20220235452
    Abstract: A production method for a glass roll includes a start preparation step (S1) of feeding-out a first lead film (LF1) coupled to a starting end portion (GFa) of a first glass film (GF1) from an unwinding device (3) and allowing a winding device (8) to wind the first lead film (LF1 after passing of the first lead film (LF1) through a thermal film-forming device (4),). The start preparation step (S1) includes a temperature increasing step of causing the thermal film-forming device (4) to be increased in temperature to a film-forming temperature. The first glass film (GF1) reaches the thermal film-forming device (4) before the thermal film-forming device (4) is increased in temperature to the film-forming temperature.
