Abstract: A pipe grooving device includes an assembly adapted to receive an end of the pipe. The assembly includes a cup which surrounds a pipe end stop. The cup and the pipe end stop may be mounted on a fixed pinion about which a carriage rotates. The carriage carries geared cams which engage the pinion and rotate synchronously when the carriage rotates relatively the pinion. The cams engage a pipe element received by the cup and form a circumferential groove in the pipe element.
