Abstract
A tubular bagging machine in which expanding elements projecting away from the fill pipe are provided in order to create bags with welded edges. A separate longitudinal welding device for welding of an area adjacent to the edge of the tube is provided. It is thus possible to produce directly side-by-side a longitudinal seam and a welded edge. A bag-opening aid or a reclosing aid can be integrated into the longitudinal seam or the edge.
