Abstract
PURPOSE: To manufacture a bend conveniently and continuously by winding a belt of paper or plastics etc. on a mandrel having a straight base and predetermined arc like tip and providing pipe forming hardable resin upon it.
CONSTITUTION: The cylindrical object 5 is shaped by winding the belt 4 of paper, plastics etc. on the mandrel A composed of the straight base 1 and the arc like tip 2 from its base. Forwarding and rotation of the cylindrical object 5 are done by the endless belt 6 wound on the cylindrical object 5, the unhardened pipe 10 is formed by winding inner face material 7, intermediate material 8 and outer face material 9 as pipe forming material composed of hardenable resin etc. on its outer periphery. The unhardened pipe is cut by the cutter 11 at the predetermined length, and hardened at the arc part 2 of the mandrel A in the curing oven 12, thus the bend is obtained continuously.
