Abstract: A manufacturing method for a band-shaped glass film (GF) includes use of: a plurality of rollers (10) configured to change a direction of the falling band-shaped glass film (GF) to a horizontal direction; and a first horizontal-conveyance unit (4) 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 (10) being at a retreated position (P2) and the first horizontal-conveyance unit (4), the plurality of rollers (10) are moved from the retreated position (P2) to a regular position (P1) 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.

Abstract: Provided is a method of manufacturing a glass film, including: a forming step of forming a band-shaped glass film (1); a conveyance direction changing step of changing a conveyance direction of the band-shaped glass film (1) from a vertically downward direction to a horizontal direction by conveying the band-shaped glass film (1) along a curved conveyance path (R1); and a horizontal conveyance step of conveying the band-shaped glass film (1) in the horizontal direction along a horizontal conveyance path (R2), wherein, when some sections of the band-shaped glass film (1) are to be discarded, the method involves: a separating step of separating a discard glass part (1x) from the band-shaped glass film (1) on the horizontal conveyance path (R2); and a discarding step of discarding the separated discard glass part (1x) by causing the discard glass part (1x) to leave the horizontal conveyance path (R2) downward.

Abstract: Provided is a workpiece conveyance method for conveying a workpiece (1) in a predetermined direction by applying a conveying force (F) to the workpiece (1) while supporting the workpiece (1) through use of free rollers (11), and the workpiece conveyance method includes: applying flows of a fluid to the free rollers (11) to apply a rotation auxiliary force (f) to the free rollers (11) in a rotation direction of the free rollers (11) during conveyance of the workpiece (1).

Abstract: Provided is a method of cleaning a surface of a glass film (1b) by causing roller brushes (2) arranged on a conveyance path to rotate in a direction reverse to a conveyance direction of a belt-shaped body (1) while conveying the belt-shaped body (1) that is obtained by coupling together end portions of the belt-shaped glass film (1b) and a leader (1a) by a sheet-shaped coupling member (1c) bonded on surfaces of the end portions. The method includes causing the roller brushes (2) to rotate forward in conformity with the conveyance direction of the belt-shaped body (1) when the coupling member (1c) passes through an arrangement region of the roller brushes (2).

Abstract: 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.

Abstract: 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.

Abstract: The manufacturing method for a glass film includes, in this order: a cleaving step of dividing a glass film (G) having a band shape into a product glass portion (Ga) and an unnecessary glass portion (Gb); and a collecting step of sequentially shattering the unnecessary glass portion (Gb), and collecting the shattered unnecessary glass portion. The cleaving step is followed by vibration regulating processing of regulating vibrations of the unnecessary glass portion (Gb) 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 (Gb) together with the collecting step executed on a downstream side of the at least one location of the vibration regulating processing.
