Abstract

L'invention concerne un coupe-tuyau comprenant une pluralité de rouleaux rotatifs (13) disposés sur deux axes parallèles l'un par rapport à l'autre et servant de support à un tuyau à couper, ainsi qu'un couteau (15) de type abaque en forme de disque servant à couper le tuyau supporté par les rouleaux (13) en le pressant pendant sa rotation. Un support de rouleau est utilisé comme les supports des rouleaux (13) et/ou du couteau (15), d'où une diminution de la force nécessaire pour couper le tuyau, la déformation du tuyau et l'apparition de bavures pouvant également être réduites.
