ABSTRACT:
Material is drawn from a roll of flat stock, passed through a pipe forming machine, and welded to provide a continuous length of pipe which is stored in a variable size loop. Pipe is withdrawn from the loop by means of a series of pipe straightening and feeding rollers which feeds the pipe to a bending machine. The bending machine is suspended from an overhead platform for rotation about a vertical axis and carries a shearing cutter so that multi-bend pipe sections, such as automobile exhaust pipes, may be bent, severed and dropped onto a conveyor for inspection and disposition while the pipe is being continuously formed from the flat stock. Distance between bends and plane of bend are respectively controlled by the pipe feeder and the bend machine rotation. Differences between forming and bending rates are compensated by varying the amount of pipe in the storage loop.
