Abstract
L’invention concerne un dispositif (100) d’extrusion pour mettre en forme d’une bande mince un produit à base d’un mélange caoutchouteux, le dispositif comprenant :- un rouleau (112) rotatif avec une rainure (112R) sous la forme d’une hélice continue mise en place à la surface extérieure (112a) du rouleau, la rainure incorporant plusieurs stries (112Ra) disposées l’une à côté de l’autre dans le sens de déplacement du mélange, et les stries étant écartées les unes des autres pour réaliser un filet au pas prédéterminé. ; et- une voûte portant sur sa surface intérieure orientée vers le rouleau des filets saillants afin de délimiter avec la surface du rouleau une chambre de plastification du mélange ;de sorte que le rouleau et la voûte sont montés de façon que des sommets de filets créés par l’hélice et les sommets de filets saillants de la voûte sont sensiblement en contact les uns par rapport aux autres. Figure pour l’abrégé : Figure 3
