Abstract

Provided is a method comprises: continuously forming an elongated, glass film having marginal portions from molten glass into a given shape having two marginal portions, in width-directional opposite edge regions thereof, wherein the glass film having marginal portions has the marginal portions, and an effective portion formed in a width-directional central region of the glass film having marginal portions; annealing the glass film having marginal portions; continuously forming resin tapes on the glass film having marginal portions at positions adjacent to and away by a given distance from the respective marginal portions, to extend in a length direction of the glass film having marginal portions; and continuously removing each of the marginal portions from the glass film having marginal portions, along a position between the marginal portion and a corresponding one of the resin tapes, or at a given width-directional position within the corresponding resin tape.
