Abstract

PURPOSE: To manufacture continuously the named profile pipe by profiling to the cross section of the mold core the unhardened pipe shaped by helically rotating and swelled by spraying water etc from the nozzle installed between the mandrel and the mold core.
CONSTITUTION: To the tip 1b of the mandrel 1 having a circular cross section is attached the mold core 3 having the base end of the circular cross section 3a and the profile changing gradually toward the tip 3b and maintaining the same peripheral length as the mandrel 1. Around the mandrel 1 near the base end 1a a paper sheet belt is wound spirally shaping a cylinder 9. The cylinder 9 proceeds helically rotating and is wound by the mold release film 10 and further by the innerface reinforcing material 12, resin concrete 13, the protecting material 14, and the outerface reinforcing material 15 are supplied, thus an unhardened pipe 11 is formed. Then the unhardened pipe is swelled by spraying water or stream inside the unhardened cylinder 11, gets a profile fitted to the cross section of the core mold 3 and is hardened in a curing oven 17, thus the profile pipe 18 is formed.
