GLASS FILM RIBBON MANUFACTURING METHOD, AND GLASS FILM RIBBON MANUFACTURING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a glass film ribbon manufacturing method for suppressing the interference of split end faces of an unnecessary part and an effective part by optimizing the support of the unnecessary part, after a glass film ribbon was split into an unnecessary part and an effective part while a glass film ribbon being transversely transported by a transfer transportation part.SOLUTION: A glass ribbon G is split, while being transversely conveyed by a transverse transportation part 4, along a split schedule line providing a boundary line between an unnecessary part G1 containing the ear parts Gx on the two widthwise sides and an effective part G2 on a widthwise center side, into an unnecessary part G1 containing the ear parts Gx on the two widthwise end sides, in a split part 5 arranged on a conveyance path of the transverse transportation part 4, and the unnecessary part G1 is then supported by an unnecessary support part 15 having a widthwise clearance 17 between the unnecessary part G1 and the effective part G2.
