ABSTRACT:
A machine for forming a metallic tubular section in which the tubular section is located, retained, has at least one end formed, filled with fluid that is then pressurized within the tube section, and bend formed into a predetermined shape, all at a single station of the machine. A second station, either coupled with or independent from the first station functions to locate a tube section, retain it, cut off a portion of the tube section, form at least one end of the tube section, and provide for removal of the tube section therefrom. The tube sections are preferably crossover fittings. The present invention further comprises a method of manufacturing a full crossover fitting and a method of manufacturing a half crossover fitting.
