Abstract

PURPOSE: An auxiliary mold with a specific shape is formed on the core mold and a resin-impregnated malding material is wound around them to form a pipe, then the core mold is released, the pipe is bended along with the auxiliary mold and cured, there by producing a bended pipe free from collapse and partial strain.
CONSTITUTION: Firstly a smooth film 6 is wound around the core mold 5 that is prepared by winding a band material around a mandrel 1. A resin-impregnated band material 7' is wound spirally thereon with a certain interval and passed through the first heating furnace 10' to form the auxiliary mold 7. A relasing film 8 is wound thereon and further a resin-impregnated molding material 9' is wound thereon to form the molded material layer 9. They are heated in the second heating f urnace and the core mold is drawn out of the pipe before the resin is completely cured to give a pipe adhered with the auxiliary mold 7. The resulting pipe is placed in the bending mold 12 and bended along the bended surface and then cured.
