Pipe bending machine enables the distance between bends, the plane of bending and the angle of curvature to be determined in advance for a number of bends to be made in a single pipe. The automatic machine uses stops to determine the distance between bends through a frame, a second group of stops to determine the bending plane, and a third group affect the angle of curvature. Four drive mechanisms move the table against a first stop, turn the pipe relative to a second stop, adjust the third stop, and operate the bending head, respectively. A signal-emitting device activates or stops each drive mechanism. |
