Abstract

La présente invention porte sur un dispositif de calibrage destiné à être utilisé dans un procédé de fabrication d'un article tubulaire, qui comprend un corps et un manchon de calibrage comportant lui-même un passage vertical pour un extrudat tubulaire extrudé, le corps présentant un perçage, une ouverture supérieure munie d'un joint supérieur et une ouverture inférieure munie d'un joint inférieur ; un canal de vide reliant le perçage à une source de vide ; un canal de liquide destiné à recevoir un flux de liquide et relié à un réservoir situé sur le haut du corps ; et un dispositif de réglage destiné à régler le niveau du liquide dans le réservoir ; et le manchon de calibrage comprenant un corps muni de multiples ouvertures et d'une collerette d'entrée ; le manchon de calibrage étant positionné de façon amovible dans le perçage et étant en contact avec le corps par l'intermédiaire de joints supérieur et inférieur. Ce dispositif de calibrage permet de fabriquer un article tubulaire d'une façon très flexible, spécialement à petite échelle au laboratoire et il peut être utilisé dans un mode libre ou dans un mode de calibrage à contact, en fonctionnement à sec ou humide. L'invention porte en outre sur un système d'extrusion destiné à fabriquer des articles tubulaires à partir d'une composition de polymère et qui comprend un tel dispositif de calibrage, ainsi que sur un procédé qui utilise un tel dispositif ou système.
