System for allowing removal of air from the interior of flexible packages, in which material can be found, including a conveyor transporting and supporting the bottom of the flexible packages or package, a second sub-system holding the top part of the package and an air extraction system. The package is raised vertically while being displaced along the conveyor. Removing the air from the packages before closing them results in a flat and straight flap, while reducing the distance between the product and the sealed or sewn joint. The process is accomplished through a continuous displacement of the package. These advantages result in packing material savings. A method for allowing removal of air is also disclosed.
L'invention porte sur un système permettant le retrait d'air de l'intérieur d'emballages souples, dans lesquels peut se trouver un matériau, lequel système comprend un transporteur transportant et supportant la partie inférieure d'un ou plusieurs emballages souples, un deuxième sous-système maintenant la partie supérieure de l'emballage, et un système d'extraction d'air. L'emballage est soulevé verticalement tout en étant déplacé le long du transporteur. Le retrait de l'air des emballages avant leur fermeture produit un volet plat et droit, tout en réduisant la distance entre le produit et le raccord scellé ou cousu. Le processus est accompli à l'aide d'un déplacement continu de l'emballage. Ces avantages conduisent à des économies de matériau d'emballage. L'invention porte également sur un procédé permettant le retrait d'air.
