摘要:
Provided is a cleaving apparatus for a band-like glass film and a cleaving method for a band-like glass film, in which at least one surface (effective surface) of the band-like glass film is held in a non-contact state to suppress a situation that wavy portions reach a region in which the band-like glass film is to be cleaved. The cleaving apparatus for a band-like glass film (1) cleaves the band-like glass film (2), which is being conveyed in a longitudinal direction thereof, along a conveyance direction thereof using a thermal stress generated through localized heating and cooling of a heated region resulting from the localized heating, the localized heating and the cooling being performed on a preset cleaving line extending along the conveyance direction of the band-like glass film (2). The cleaving apparatus includes: a conveyor (3) for supporting a back surface side of the band-like glass film (2); and an air knife (5) for supplying air to a front surface of the band-like glass film (2) while supporting, by the conveyor (3), the back surface side of the band-like glass film (2) to retain the band-like glass film on the conveyor (3) at a position on an upstream side of a cleaving region (R), in which the band-like glass film (2) is to be cleaved, in the conveyance direction.
摘要:
A sheet roll (1) is manufactured by placing a sheet-like coupling member (3) on end portions of a plurality of glass films (g) so as to span therebetween, coupling the end portions of the glass films (g) together, and rolling the coupled plurality of glass films (g). The sheet-like coupling member (3) used in the sheet roll (1) includes wide width portions (4) for forming wide joint portions joined to the glass films (g) at each of both end portions thereof in a rolling direction, and a necked portion (5), which is narrower than the wide width portions (4) and is formed at a middle portion thereof in the rolling direction.
