    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 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.

    Abstract: The invention encompasses a device for forming a circumferential groove in a pipe element having a longitudinal axis. In an example embodiment, the device comprises a drive roller rotatable about a drive roller axis. The drive roller is engageable with an inner surface of the pipe element when the drive roller axis is oriented substantially parallel to the longitudinal axis of the pipe element. A grooving roller is rotatable about a grooving roller axis oriented substantially parallel to the drive roller axis. The grooving roller is movable toward and away from the drive roller so as to forcibly engage an outer surface of the pipe element so as to displace material of the pipe element and form the groove therein upon rotation of the pipe element. An idler roller is rotatable about an idler roller axis oriented substantially parallel to the drive roller axis. The idler roller has a known diameter. The idler roller is movable toward and away from the drive roller so as to engage an outer surface of the pipe element so as to rotate upon rotation of the pipe element. A first sensor determines a degree of rotation of the idler roller and generates a first signal indicative thereof. A second sensor determines a degree of rotation of the pipe element and generates a second signal indicative thereof. A control system is adapted to receive the first and second signals and use the first and second signals to determine a diameter of the groove, and control motion of the grooving roller toward and away from the drive roller in response to the diameter of the groove.

    Abstract: A method of forming circumferential grooves (72) in pipe elements (40) using opposed rollers (12, 22) to cold work the pipe elements (40) determines the diameter (74a) of the groove (72) while the pipe element (40) is rotated between the rollers (12, 22). A device for executing the method uses the instantaneous determinations of the groove diameter (74a) in a feed-back loop to control the operation of the device and halt groove (72) formation when the groove diameter (74a) is within a specified tolerance.

    Abstract translation: 使用相对辊（12,22）在管元件（40）中形成周向槽（72）以冷作管元件（40）的方法确定了槽（72）的直径（74a），而管元件 ）在辊（12,22）之间旋转。 用于执行该方法的装置使用反馈回路中的凹槽直径（74a）的瞬时确定来控制装置的操作并且当凹槽直径（74a）在指定的公差内时停止凹槽（72）的形成。
