Abstract

L'invention a pour objet un procédé de fabrication par extrusion de pièces en matière thermoplastique. Selon l'invention, on extrude de la matière plastique sous forme d'un élément tubulaire, on sépare cet élément en deux dans le sens longitudinal de manière à former deux éléments de feuilles situés de part et d'autre du plan médian dudit élément tubulaire et, après les avoir découpés suivant le contour désiré, on applique ces deux éléments de feuille simultanément contre la paroi d'empreintes de moule disposées de part et d'autre dudit plan médian.
