Abstract

Cette invention concerne un dispositif de fermeture comprenant une première et une seconde bandes de fixation encastrables. La première bande de fixation comporte un élément de fermeture réalisé par extrusion sur une partie rebord. L'élément de fermeture et la partie rebord sont faits de matériaux de densités différentes, ce qui permet d'agir sur la forme des bandes de fixation. Ce différentiel de densité permettent d'atténuer ou de supprimer l'effet de cintrage des bandes de fixation qui apparaît pendant le processus de fabrication. Comme l'élément de fermeture a une moindre densité, mais un volume plus important, et que la partie rebord est faite dans un matériau à la densité plus élevée, le taux de cristallisation de cette partie est le même que celui de l'élément de fermeture. Cette différence de densité permet d'atténuer ou d'éliminer le cintrage des bandes de fixation.
