Abstract

PURPOSE: To manufacture a bent pipe excellent in a thickness accuracy by coating with an elastic member sheet a cylindrical member while forming a shaping material layer thereon, which moves in the axial direction while rotating on a core body and then extracting the core body, inserting the elastic body, bending and hardening the same.
CONSTITUTION: A long body such as paper or the like is wound around a core body 1 in a spiral form to bond the same thereto thereby forming a cylindrical body 4. A mold parting paper 5 is wound around the cylindrical body 4, and a forming material 61' containing a reinforcing material such as a glass roving or the like and an unsaturated polyester resin is further wound thereon to form an inner surface layer 61 and further form an intermediate layer 62 consisting of a resin mortar and an outer surface layer 63 of a material the same as the material of the inner surface layer 61. An elastic body sheet 63, and then the core body 1 is extracted, cutting the thus formed tubular body at a suitable position. An elastic cylinder 8 such as silicone rubber or the like is inserted into the tubular body 4 the forming material layer 6 of which is not completely hardened, and a curved shaft 9 having a specific curvature is inserted therein and bent, heated and hardened as it is. Then, the curved shaft 9, elastic cylinder 8, cylindrical body 4, and elastic sheet 7 are eliminated thereby to manufacture a bent pipe.
