Title:
GLASS FILM CUTTING METHOD, GLASS ROLL PRODUCTION METHOD, AND GLASS FILM CUTTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/011445
Kind Code:
A1
Abstract:
Disclosed is a glass film cutting device (1) that uses thermal stress generated by local heating and cooling of the heated area along a planned cutting line (7) in a glass film (G) to move an initial crack (10) formed in the end section of the planned cutting line (7) forward along the planned cutting line (7). The glass film cutting device (1) positions a resin sheet (R) that is more flexible than the glass film (G) in the cutting area and blows air from a levitation means (3) on to the bottom surface of the resin sheet (R) to levitate said resin sheet. The glass film cutting device (1) then covers and holds up and supports the planned cutting area, which includes the planned cutting line (7) in the glass film (G), with the levitated resin sheet (R) and, in this state, cuts the glass film (G).
