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.

L'invention concerne un outil à molettes servant à réaliser des rainures circulaires autour d'un tuyau. L'outil tourne autour d'un axe de rotation et présente une surface circonférentielle qui vient au contact du tuyau. La surface de l'outil présente une première et une seconde parties superficielles placées selon une relation espacée et orientées perpendiculairement à l'axe de rotation. Une partie superficielle radiale s'étendant entre la première et la seconde parties superficielles est orientée de manière sensiblement parallèle à l'axe de rotation. Une partie superficielle angulaire adjacente à la seconde partie superficielle est orientée selon un angle pouvant atteindre 70· et s'étendant en pente à partir de la seconde partie superficielle.
