Abstract
Des systèmes et des méthodes sont décrits pour la fabrication de colliers de compression pour renforcer des raccords étanches entre une longueur de tuyau et un raccord de plomberie. Plus précisément, des colliers de compression et des méthodes connexes de fabrication comprennent lextrusion dun tube creux comportant une ou plusieurs stries qui sont ensuite partiellement éliminées ou taillées pour fournir des languettes de positionnement sur une extrémité du collier de compression. Les colliers de compression peuvent être coupés à la longueur souhaitée à partir du tube creux extrudé. De cette manière, des colliers de compression disposant de caractéristiques pour améliorer la résistance et la fiabilité dun ajustement serré, ainsi que leur facilité dutilisation, peuvent être fabriqués rapidement en produisant peu de déchets, grâce à des modifications du procédé dextrusion.
