Abstract
A device for cold working pipe elements has two or more cams, each having a gear, the gears being synchronized to turn all of the cams. Each cam has a cam surface with a region of increasing radius and may have a region of constant radius extending around a cam body. One or more cams may also have a traction surface extending around a cam body. A discontinuity in each cam surface is aligned with a gap in the traction surface of each cam. The discontinuities and gaps provide clearance for insertion and removal of the pipe element between the cams to form a circumferential groove when the cams are rotated. An engagement body is mounted between the cams to engage and disengage from a stop surface on one of the cams. Engagement between the engagement body and a stop surface prevents rotation of the cams.
