Abstract

L'invention concerne un procédé et un dispositif d'extrusion d'un matériau pour la fabrication de sacs comportant des profils de fermeture et des nervures d'alignement; l'invention concerne également le matériau concerné. Ce matériau comprend un film (10) destiné à former la paroi du sac et qui peut être extrudé sous forme d'un tube, le film (10) étant pourvu d'un profil mâle (12) et d'un profil femelle complémentaire (13) constituant la fermeture à emboîtement, au moins une nervure d'alignement (22; 23), parallèle et espacée du profil mâle (12), ainsi qu'une moulure stabilisatrice (50) qui sert de renfort pour le profil mâle (12) et les nervures d'alignement (22, 23). Dans la fabrication, les extrudats servant à former le film et la ou les nervures d'alignement peuvent provenir de sources séparées de façon à pouvoir utiliser des matières plastiques différentes ayant des matières plastiques différentes ayant des caractéristiques différentes, tandis que la ou les nervures d'alignement et la ou les moulures de stabilisation peuvent être formées d'une même matière plastique provenant d'une source commune.
