Abstract

L'invention concerne un dispositif de moulage d'un film stratifié et un procédé de moulage d'un film stratifié, par lesquels il est possible de mouler convenablement un film stratifié ayant différentes formes. Le dispositif de moulage (2) d'un film stratifié comprend une première filière de moulage (20) et une deuxième filière de moulage (30). La première filière de moulage (20) possède une section en renfoncement (20a) et des sections en saillie (20b, 20c). Les sections en saillie (20b, 20c) sont disposées sur les deux côtés de la section en renfoncement (20a). La deuxième filière de moulage (30) est disposée en regard de la première filière de moulage (20). La deuxième filière de moulage (30) possède une pluralité de poinçons et de mécanismes d'avance/recul (41). La pluralité de poinçons est, dans une vue en plan, disposée à l'intérieur de la section en renfoncement (20a). Les mécanismes d'avance/recul (41) sont prévus pour chacun de la pluralité de poinçons. Les mécanismes d'avance/recul (41) font avancer et reculer les poinçons vers la section en renfoncement (20a), et en s'éloignant de cette dernière.
