Abstract
Cette invention concerne des procédés, un appareil et un système permettant de former des sacs à usage multiple ou des composants de ces derniers. Les sacs à usage multiple (2001) sont faits d'un matériau de base de type voile sur lequel ont été appliqués des segments transversaux de film de fermeture. Ce matériau de type voile est traité selon un procédé de formation, de remplissage et de scellage vertical du sac. Ce procédé consiste à faire défiler une bande continue de film qui possède des éléments profilés de fermeture mâle et femelle disposés en travers du voile afin d'assurer le scellage sur ce dernier. Dans un mode de réalisation, on fait appel à une bande continue d'un matériau faisant barrière, ainsi qu'à une bande continue de fermeture qui se compose d'une première et d'une seconde bande à profil de fermeture réciproque. Ces bandes sont placées sur la bande continue de film et fixées à cette dernière. Le film faisant barrière est plié de manière à former un pli ainsi que deux parties opposées de connexion de bande de fermeture du film faisant barrière. Le pli est ensuite fendu de manière à former deux bandes continues et distinctes du matériau faisant barrière, ainsi que deux bandes continues de film. Dans un autre mode de réalisation, un revêtement est appliqué sur le film proprement dit de manière à ce que le film fendu et plié ne puisse se sceller sur lui-même. Le film et la fermeture ainsi obtenus sont ensuite découpés (220) et agencés de manière adéquate sur le voile, ceci grâce au système unique de bande sous vide décrit dans cette invention, et grâce aux dispositifs d'entraînement interconnectés du film et du voile ainsi qu'à la connexion qui les relie à la machine de formation, de remplissage et de scellage.
