Abstract
A method of forming circumferential grooves in pipe elements using opposed rollers to cold work the pipe elements determines the diameter of the groove while the pipe element is rotated between the rollers. A device for executing the method uses the instantaneous determinations of the groove depth in a feed-back loop to control the operation of the device and halt groove formation when the groove depth is within a specified tolerance.
