Claims

[Scope of utility model registration request]

A drum provided to rotate in one direction, a guide plate provided on one side of the upper circumferential surface of the drum to guide a band-shaped metal plate that is fed so as to be spirally wound around the drum, and a guide plate provided on the upper side of the upper circumferential surface of the drum. At the same time, the single edge of the band wrapped at the tip of the metal band plate and the double edge of the band wrapped later pass, and the double edge drawn during the passage becomes a single gap. A first roll for pressing is provided so that the meshed double seams and single seams are pressed against the drum and slightly tilted, and This is a manufacturing device for a curved joint pipe, which comprises a second roll provided to press the folded double seam and single seam against a drum so that they are completely laid down.
