Zusammenfassung:	To provide a belt-like member for rehabilitating an existing pipe capable of securing flowing capacity in normal times and reliably exhibiting seismic performance.SOLUTION: A belt-like member 10 for rehabilitating an existing pipe that includes a main belt portion 11 and a telescoping belt portion 12 that straddles an intermediate portion 11c of the main belt portion 11 is manufactured by a manufacturing apparatus 20. The belt-like member 10 is extrusion molded so that a weld line 15 is formed at the intermediate portion 11c of the main belt portion 11 by an extrusion molding unit 21 of the apparatus 20. Thereafter, the main belt portion 11 is cut at the weld line 15 by a cutting mechanism 33 to form a cut portion 16.SELECTED DRAWING: Figure 4 【課題】平常時は流下能力を担保し、かつ耐震性能を確実に発現し得る既設管更生用帯状部材を提供する。【解決手段】主帯部１１と、該主帯部１１の中間部１１ｃを跨ぐ伸縮帯部１２を含む既設管更生用帯状部材１０を製造装置２０によって製造する。装置２０の押出成形部２１によって、主帯部１１の中間部１１ｃにウェルドライン１５が形成されるように、帯状部材１０を押出成形する。その後、割断機構３３によって、主帯部１１をウェルドライン１５において割断し、割断部１６を形成する。【選択図】図４
