A vertical bag forming, filling and sealing machine having a feed system for a wrapping material forming the flexible tube bags, a filling tube, a longitudinal seam welding device and a cross seam welding device is described. The cross seam welding device comprises a unit forming the lower cross weld seam and a unit forming the upper cross weld seam of a flexible tube bag. The unit for generating the upper cross weld seam or a folding device and a lifting device for the filled flexible tube bag are movable up and down and are lifted for the generation of the upper cross weld seam or for the folding of the flexible tube bag in order to relax the wrapping material. By this the air space over the surface of the filling material is kept as small as possible.
achine verticale servant à former, remplir et fermer des sacs, munie d'un système d'alimentation en matériau d'emballage pour la formation de sacs en forme de tube flexible, d'un tube de remplissage, d'un dispositif de soudure longitudinal et d'un dispositif de soudure transversal. Ce dernier comporte un élément servant à la formation du joint transversal inférieur et un autre à la formation du joint transversal supérieur d'un sac en forme de tube flexible. L'élément de formation du joint transversal supérieur ou un dispositif de pliage et un dispositif de levage du sac rempli peuvent être déplacés verticalement pour réaliser le joint transversal supérieur ou pour plier le sac en forme de tube flexible afin d'assouplir le matériau d'emballage. De cette manière, l'espace d'air au-dessus du produit emballé demeure aussi réduit que possible.
