Abstract
Suivant l'invention, pour modifier l'épaisseur d'un corps extrudé à débit constant et entraîné par des organes de roulement motorisés, tout en maintenant constante la vitesse de rotation des organes de roulement, on produit un mouvement relatif de translation entre ces organes et l'extrudeuse. L'invention s'applique notamment à la formation périodique de surépaisseurs internes dans un tube continu en matiere thermoplastique en vue du tronçonnage de ce tube et de l'expansion des parties épaissies pour former des emboîtements de raccordement.
