Abstract

L'invention concerne un outil à rouler les filets destiné à rouler et/ou à réparer un filet, comprenant un dispositif de serrage (12) destiné à être fixé à une extrémité de tube (18) et au moins un rouleau profilé (14.1) destiné à rouler un filet dans l'extrémité de tube (18) ou à réparer un filet à l'extrémité de tube (18). Selon l'invention, ledit rouleau profilé (14.1) se rétrécit dans une direction d'avance du rouleau profilé (14), ce qui permet de rouler un filet qui se rétrécit, notamment un filet conique, dans l'extrémité de tube (18).
