To separate at least one edge part of a glass ribbon, having beads at opposite edge parts, from its center part.SOLUTION: A supply source 105 is provided for a glass ribbon 103 having a pair of opposite edge parts 201, 203 and a center part 205 spreading laterally between the opposite edge parts, and the glass ribbon is passed through a descent zone 123 in a facing-down direction 121 to the supply source. The glass ribbon is bent in a bending zone 125 downstream from the descent zone, and the glass ribbon includes an upward concave surface while passed through the bending zone. The glass ribbon is passed to a cutting zone 147 downstream from the bending zone, and further bent in the cutting zone to provide a bent target segment 151 having a bending arrangement in the cutting zone. In the cutting zone, at least one edge part is separated from the center part of the bent target segment.SELECTED DRAWING: Figure 2 【課題】対向するエッジ部分にビードを有するガラスリボンにおいて、少なくとも１つのエッジ部分をその中心部分から分離する。【解決手段】一対の対向エッジ部分２０１，２０３と、この対向エッジ部分間に横方向に広がる中心部分２０５とを有するガラスリボン１０３の供給源１０５を提供し、ガラスリボンを供給源に対して下向き１２１に、下降ゾーン１２３に通過させる。このガラスリボンを、下降ゾーンの下流の曲げゾーン１２５において屈曲させ、このガラスリボンは曲げゾーンを通過している間、上方凹状表面を含んでいる。ガラスリボンを曲げゾーンの下流の切断ゾーン１４７へと通過させ、さらにガラスリボンを切断ゾーンにおいて屈曲させて、屈曲配置を有する屈曲ターゲットセグメント１５１を切断ゾーン内で提供する。切断ゾーン内において、エッジ部分の少なくとも一方を屈曲ターゲットセグメントの中心部分から分離させる。【選択図】図２
