    • 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 (8) extending in a predetermined conveying direction (a) by a thermal stress generated through localized heating performed along the preset cleaving line (8) 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 (10), which are obtained by the dividing, so that the adjacent divided glass films (10) 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 (10).
    • 本发明提供一种玻璃膜(G)的切割方法,该切割方法包括以下步骤:在沿预定切割线(8)延伸的预定切割线(8)上沿预定方向传送玻璃膜(G) 方向(a)通过沿着预设劈裂线(8)进行局部加热并通过局部加热区域(H)的冷却产生的热应力; 沿玻璃膜(G)的宽度方向分割玻璃膜(G); 在分割之后,通过分割获得的相邻分隔玻璃膜(10)转向,使得相邻分隔玻璃膜(10)在相邻分隔玻璃膜的前后方向上分离; 以及在分割玻璃膜(G)之后和转移相邻的分隔玻璃膜(10)之前,在相邻分隔玻璃膜之间形成预定宽度间隙。
