Abstract

L'invention concerne un procédé et un dispositif de fabrication d'un profilé extrudé sans symétrie de rotation, composé de plusieurs composants de mélange situés les uns contre les autres le long de couches limites. L'invention vise à améliorer sensiblement la fabrication du profilé extrudé. A cet effet, les coordonnées des couches limites au moins de certains composants de mélange du profilé extrudé sont détectées au moyen d'un procédé de mesure pénétrant dans le profilé extrudé. Ainsi, il est possible pour la première fois de détecter les coordonnées de certains composants, en particulier par conséquent de certains composants du profilé, afin d'obtenir une répartition des épaisseurs de couches et des couches limites correspondant aux valeurs théoriques. Le fait d'utiliser un procédé de mesure pénétrant dans le profilé extrudé permet de déterminer également les coordonnées des couches limites qui sont entièrement recouvertes par d'autres composants.
