Abstract

L'invention concerne un procédé destiné à la fabrication d'un conduit ondulé à trois couches conçu sur la base d'un agencement formé par une couche ondulée centrale (2) disposée sur une couche cylindrique lisse (1), sur laquelle une troisième couche (3) est appliquée à l'aide d'une tête d'extrusion qui applique la troisième couche (3) de manière uniforme sur les crêtes de la couche ondulée centrale (2), ce qui permet de réguler l'épaisseur de la troisième couche (3). Le procédé consiste ensuite à étendre au moins une des extrémités libres afin de former un raccord étanche entre des sections de conduit, l'ensemble formé comprenant une section inclinée suivie d'une section horizontale, puis d'un ré-élargissement dont la partie inférieure comporte un logement pour un joint élastomère.
