(EN) Method and device for forming grooves in pipe elements
Abrégé
(EN)

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 diameter in a feed-back loop to control the operation of the device and halt groove formation when the groove diameter is within a specified tolerance.
