Abstract
PURPOSE: To obtain a bend simply and at low cost by covering the outside of the mandrel with the paper tube and forming the pipe by winding the pipe formig members such as thermosetting resin etc. on the outer periphery, thereafter drawing the mandrel and shaping the pipe in a bend mold.
CONSTITUTION: A mandrel A is composed of plural ring pieces 1 inserted with a shaft 3, and a thin-walled paper pipe 5 covers its outside, and pipe forming hardenable members of inner face reinforcing material 10, intermediate resin 11, outer face reinforcing material 12 etc. are wound, so the pipe is made. The pipe from which the mandrel A is drawn is hardened in a bend mold 14 and the desired bend is obtained. The mandrel A may remain in the paper pipe if required, the ring pieces form properly the flexible state in this case.
