Abstract
After a glass film ribbon is formed while allowing a glass to descend, the glass film ribbon is annealed while allowing the glass film ribbon to descend in an annealer to remove an internal strain. Then, when the glass film ribbon having a thickness at a center portion excluding both widthwise ends of 300 μm or less is cut, after processing in the annealer is executed and before a cutting step is executed, main tensile rollers that play a role as principal tensile rollers hold the descending glass film ribbon and are driven to rotate, to thereby provide at least the glass film ribbon in the annealer with tension in a vertical direction.
