Abstract

Official abstract text for this publication.

A device for cold working pipe elements has two or more cams, each having a gear. The gears turn synchronously with one another. 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. Each cam also has 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.

First claim

Opening claim text (preview).

What is claimed is: 1. A device for cold working a pipe element, said device comprising: a housing; a plurality of gears mounted within said housing, said gears being synchronously rotatable relative to one other about respective axes of rotation, said axes of rotation being parallel to one another, said gears being positioned about a central space for receiving said pipe element; a pinion mounted within said central space within said housing, said pinion meshing with each gea…
