A manufacturing method for a band-shaped glass film (GF) includes use of: a plurality of rollers () configured to change a direction of the falling band-shaped glass film (GF) to a horizontal direction; and a first horizontal-conveyance unit () configured to convey the band-shaped glass film (GF) in the horizontal direction after the changing of the direction of the band-shaped glass film (GF). After a lower end of the band-shaped glass film (GF) passes through a position between the plurality of rollers () being at a retreated position (P) and the first horizontal-conveyance unit (), the plurality of rollers () are moved from the retreated position (P) to a regular position (P) to apply a pressing force to the band-shaped glass film (GF), to thereby cut the band-shaped glass film (GF) along a width direction by bend-breaking.

Method and device for producing band-shaped glass film

Provided is a workpiece conveyance method for conveying a workpiece () in a predetermined direction by applying a conveying force (F) to the workpiece () while supporting the workpiece () through use of free rollers (), and the workpiece conveyance method includes: applying flows of a fluid to the free rollers () to apply a rotation auxiliary force (f) to the free rollers () in a rotation direction of the free rollers () during conveyance of the workpiece ().

Workpiece conveyance method and workpiece conveyance device

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.

Manufacturing method for a glass film

A manufacturing apparatus prevents small defects from being formed in a surface of a glass film ribbon to the extent possible when the glass film ribbon is transported toward a downstream side while curved. The apparatus includes a direction converting device for converting a traveling direction of the glass film ribbon, which is drawn downward vertically from a forming device, from a vertical direction to a horizontal direction by transporting the glass film ribbon toward a downstream side while curved in a longitudinal direction of the glass film ribbon. The direction converting device includes a curve-supporting unit for supporting the glass film ribbon curved in the longitudinal direction. The curve-supporting unit includes two lines of end portion supporting parts for supporting widthwise end regions of the glass film ribbon without supporting a widthwise central region of the glass film ribbon.
