METHOD AND APPARATUS FOR FORMING PIPE REINFORCING CAGES AND LIKE CLOSED LOOP OBJECTS The invention relates to a method of forming pipe reinforcing cages, pipe or like closed loop member from a formable workpiece. The method includes the steps of gripping opposite ends of the workpiece and advancing the ends toward one another while simultaneously rotating the ends toward one another such that the workpiece is formed to define a closed loop as the ends thereof are brought together. They also include the additional step of synchronizing the advancing step with the rotating step to define a predeterminod shaped loop as the ends are brought together. 1.
