In the suspension sections (24), there are provided in the end that is to the rear in the direction of delivery during packaging notches (30) which extend to the edge of the suspension sections (24) and which facilitate the blowing-open of the bags (22) in an air curtain that is disposed substantially in the bag plane and is directed towards the filling aperture of the bag. For the very first lifting of the bag front wall, there may be provided in the bag rear wall, at the level of the end of the front wall of the bag, additional holes (18) through which a jet that is vertical on the bag plane can be directed towards the front wall of the bags. To enlarge the transversal zone (W), within which the bags (22) can be separated from the carrying strip (20) by a cut extending in the longitudinal direction of the web, provision is made for the notches (30) to be provided with a substantially transversal section (30a) which extends from the interior end of the notches (30) transversally to the exterior. |
