Abstract

L'invention porte sur un appareil de soudage bout à bout d'une canalisation en plastique comprenant une base (11), une paire de colliers de serrage (21), chacun étant destiné à recevoir une partie finale de la longueur d'une canalisation en plastique (50), les colliers de serrage reposant sur la base face à face, ce qui fait que les extrémités des parties finales reposant sur les colliers de serrage sont quasiment coaxiales. Les colliers de serrage sont en mesure de se rapprocher et de s'éloigner l'un de l'autre et présentent une dimension axiale permettant de serrer une partie de la longueur de la partie finale respective adjacente à l'extrémité. On prévoit également un élément chauffant (39) reposant sur la base adjacente à une position intermédiaire des colliers de serrage et susceptible de se déplacer d'une première position entre les colliers de serrage à une seconde position écartée latéralement de la première position. Les faces planes opposées de l'élément chauffant sont disposées face à face par rapport aux colliers de serrage et sont transversales par rapport à l'axe central des parties finales lorsque l'élément chauffant se trouve dans la première position. Les colliers de serrage sont dotés d'un organe de préhension (33) permettant un mouvement mutuel des colliers de serrage.
