Abstract
Provided is a cleaving method for a glass film (G) including: cleaving, during conveyance of the glass film (G) in a predetermined direction, the glass film (G) continuously along a preset cleaving line () extending in a predetermined conveying direction (a) by a thermal stress generated through localized heating performed along the preset cleaving line () and through cooling of a locally heated region (H); dividing the glass film (G) in a width direction of the glass film (G); diverting, after the dividing, adjacent divided glass films (), which are obtained by the dividing, so that the adjacent divided glass films () are separated in a front and rear direction of the adjacent divided glass films; and forming a predetermined widthwise clearance between the adjacent divided glass films after the dividing of the glass film (G) and before the diverting of the adjacent divided glass films ().
