Abstract

L'invention concerne un procédé de façonnage destiné à former une partie extensible, rendue extensible dans la direction de son épaisseur, sans rompre une feuille en polymère thermoplastique, et une feuille fabriquée par le procédé de façonnage. Le procédé de façonnage façonne la partie extensible, extensible dans la direction de l'épaisseur de la feuille (10) en polymère thermoplastique, à l'aide d'un moule stationnaire (5) et d'un moule mobile (6) qui présentent plusieurs lames de moulage (2). Les lames de moulage sont configurées de telle sorte qu'au moins des courbes ou des lignes incurvées dont les sections ont des formes similaires projetées sur la feuille sont agencées autour du centre de similitude et de telle sorte qu'elles s'étendent séparément dans la direction de l'épaisseur de la feuille depuis le moule stationnaire et le moule mobile sans être en contact les unes avec les autres mais en s'engrenant en alternance les unes dans les autres. Le procédé de façonnage comprend l'étape qui consiste à introduire la feuille entre le moule stationnaire et le moule mobile et l'étape qui consiste à amener les lames de moulage du moule stationnaire et du moule mobile à s'engrener pour ainsi étendre la feuille entre les extrémités de tête des lames de moulage adjacentes. La feuille est fabriquée à l'aide de ce procédé.
