ABSTRACT:
A spiral pipe has an integrated radial flange. A machine for forming such a flange comprises a rotor which rotates and a flange roller mechanism connected to the rotor via slides. As the rotor rotates, the flange roller mechanism moves radially via the slides to form an integrated flange on an end portion of the spiral pipe.
