によって補強された樹脂管であり、また異形管とは横断
面が非円形、例えば四角形、卵形等の管のことである。The term "reinforced resin tube" as used herein refers to a resin tube that contains and is reinforced by a fibrous material, and the term "unusual tube" refers to a tube whose cross section is non-circular, such as square or oval.

して強化樹脂管を得ることがある。Conventionally, when manufacturing reinforced resin pipes continuously, for example, an endless belt is spirally wound at least once around a core frame fixed in a cantilevered manner, and a long length of belt is wound between the endless belt and the core frame. The endless belt is rotated to wrap the belt-like material around the core frame, forming a tube that advances toward the tip, and supplying the fiber material and hardening resin onto the tube. A reinforced resin tube may be obtained by heating the resin from the surroundings to harden the resin while the tube advances distally along the core frame.
