Roller tool for forming grooves in pipes
First Claim
1. A roller tool for forming circumferential grooves around a pipe, said roller tool being rotatable about an axis of rotation and having a circumferential surface engageable with said pipe, said surface comprising:
- a first surface portion oriented substantially perpendicularly to said axis of rotation;
a second surface portion positioned in spaced apart relation to said first surface portion and oriented angularly with respect to said axis of rotation;
a radially facing surface portion extending between the first and second surface portions and oriented substantially parallel to said axis of rotation.

Abstract
A roller tool for forming circumferential grooves around a pipe is disclosed. The tool is rotatable about an axis of rotation and has a circumferential surface engageable with a pipe. The tool surface includes first and second surface portions positioned in spaced relation and oriented perpendicularly to the axis of rotation. A radial surface portion extends between the first and second a surface portions and is oriented substantially parallel to the axis of rotation. An angled surface portion is positioned adjacent to the second surface portion. The angled surface portion is oriented at an angle up to about 70° and slopes away from the second surface portion.
