Abstract

L'invention concerne une matrice de co-extrusion pour la production de film ou feuille multicouche en matériau thermoplastique. Cette matrice comprend une sortie de matrice, une première partie de matrice pour la production d'une couche centrale, et une deuxième partie de matrice pour la production d'une première couche superficielle, cette partie comportant un répartiteur de flux transversal qui présente un trajet d'écoulement de flux caractérisé en ce qu'une partie d'un flux en fusion du matériau thermoplastique traverse la longueur de la deuxième partie plus d'une fois; enfin, il existe une troisième partie de matrice pour la production d'une seconde couche superficielle, qui comprend un répartiteur de flux transversal, lequel présente un trajet d'écoulement de flux caractérisé en ce qu'une partie d'un flux en fusion du matériau thermoplastique traverse la longueur de ladite partie plus d'une fois.
