Provided is a glass film ribbon manufacturing device (), including: a transverse conveyance unit (), which is configured to convey a glass film ribbon (G) in a transverse direction; and a cleaving unit (), which is arranged on a conveyance path of the transverse conveyance unit (), and is configured to cleave the glass film ribbon (G) along a preset cleaving line extending in a longitudinal direction, the transverse conveyance unit () including a wrinkle-smoothing unit () configured to smooth a wrinkle generated in the glass film ribbon (G) before the glass film ribbon (G) is cleaved by the cleaving unit ().

Glass film ribbon manufacturing method and glass film ribbon manufacturing device

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.

Manufacturing method for a glass roll and manufacturing apparatus for a glass roll

A manufacturing method for a glass film includes a cleaving step of dividing a glass film having a band shape into a product glass portion and an unnecessary glass portion, and a collecting step of sequentially shattering the unnecessary glass portion, and collecting the shattered unnecessary glass portion. The cleaving step is followed by vibration regulating processing of regulating vibrations of the unnecessary glass portion in a thickness direction thereof, the vibration regulating processing being executed in at least one location in the longitudinal direction of the unnecessary glass portion, and the collecting step being executed on a downstream side of the at least one location of the vibration regulating processing.
