Abstract

L'invention concerne un procédé de façonnage comprenant : une première étape d'agencement (S102) qui consiste à façonner un stratifié en pressant contre un gabarit de façonnage, un premier moule de façonnage dont la forme correspond à celle d'une première région du gabarit de façonnage dans une direction de hauteur, et à agencer le premier moule de façonnage dans une position axiale prédéfinie ; une première étape de déplacement (S103) qui consiste à déplacer le premier moule de façonnage le long de la direction axiale, dans un état dans lequel le premier moule de façonnage est pressé contre le gabarit de façonnage ; une seconde étape d'agencement (S104) qui consiste à façonner un stratifié en pressant contre le gabarit de façonnage, un second moule de façonnage dont la forme correspond à celle d'une seconde région comprenant la première région, qui est une région du gabarit de façonnage dans la direction de hauteur et est plus large que la première région, et à agencer le second moule de façonnage dans une position prédéfinie ; et une seconde étape de déplacement (S105) qui consiste à déplacer le premier moule de façonnage et le second moule de façonnage dans la direction axiale, pendant que le premier moule de façonnage et le second moule de façonnage sont pressés contre le gabarit de façonnage.
