Abstract
A manufacturing method for a glass roll includes drawing a glass film downward vertically from a forming device, converting a delivery direction of the glass film from a vertical direction to a horizontal direction, continuously delivering the glass film to a downstream side by a horizontal conveyance section, and rolling the glass film into a roll shape on a downstream side of the horizontal conveyance section. While the glass film is supported in surface contact by an endless belt serving as a support section, which is provided in the horizontal conveyance section, a rolling force equal to or less than a static friction force, which is generated by a self-weight of the glass film between the glass film and the endless belt, is imparted to the glass film.
