Abstract

L'invention concerne un redresseur (21) comportant une plateforme (20) adaptée pour être engagée dans un logement ménagé dans la surface externe d'une virole interne, ladite plateforme (20) comportant : - une gorge intrados (27) formant un espace adapté pour maintenir un joint (30) lorsqu'elle est en vis-à-vis d'une deuxième gorge (29) d'une deuxième plateforme (28) d'un deuxième redresseur (22) coopérant avec ladite virole interne, de sorte à espacer la plateforme (20) de la deuxième plateforme (28) ; une gorge extrados (33) formant un espace adapté pour maintenir un joint (36) lorsqu'elle est en vis-à-vis d'une troisième gorge (34) d'une troisième plateforme (35) d'un troisième redresseur (23) coopérant avec ladite virole interne, de sorte à espacer la plateforme (20) de la troisième plateforme (35) ; la gorge intrados (27) et la gorge extrados (33) étant positionnées sur des parois opposées de la plateforme (28).
