PROBLEM TO BE SOLVED: To restrict a protrusion of metallic reinforcement material even if a bending action is applied to it and perform a smooth manufacturing of high rigidity regeneration pipe.SOLUTION: A reinforcement material embedded band-like member 1 is constituted by a hard vinyl chloride band-like member 2 comprising a band-like base plate 21, a plurality of ribs 22 up-righted from the base plate 21 and connecting portions 23, 24 each of which is up-righted at one edge part and the other edge part of the base plate 21; and metallic reinforcement members 3 buried in each of the ribs 22 of the hard vinyl chloride band-like member 2. Inner side of each of the ribs 22 of the hard vinyl chloride band-like member 1 has a clearance 22x in a vertical direction of the metallic reinforcement member 3. Then, when the reinforcement material embedded band-like member 1 is wound into a helical shape, adjoining connecting portions 23, 24 are connected with each other to manufacture a regeneration pipe, even if the reinforcement material embedded band-like member 1 is bent, deformation of the metallic reinforcement members 3 is absorbed within the clearance 22x so as to prevent it from being protruded. |
