Abstract:
1. A vertical tubular bagging machine comprising a foil web unwound from a storage roller, a forming shoulder for reshaping the foil web into a foil tube, a foil-removing device for the further transport of the foil web and of the foil tube, a vertically aligned fill pipe for receiving and filling of the foil tube, a longitudinal-sealing device for welding of edges of the foil web and thus for creating a longitudinal sealing seam of the foil tube, a cross-sealing device with welding jaws, which are movable against one another and weld the foil tube transversely with respect to its transport direction, for creating top seams and bottom seams on tubular bags, and a separating device for separating the tubular bag from the foil tube, wherein the forming shoulder has a curved guiding edge at an upper edge of a shoulder connection surrounding the fill pipe and a shoulder sleeve fastened to the curved guiding edge and pointing outwardly away from the guiding edge, wherein the shoulder sleeve is formed of two separate sleeve parts, wherein the shoulder connection is formed of two separate connection pieces, such that each said one sleeve part and an adjoining said connection piece form a component, wherein the two components define the forming shoulder, wherein the fill pipe is formed out of two troughs aligned against one another, with one said trough being releasably connected to the other trough to enable access into an interior of the fill pipe, and wherein one said component can be removed from the other component in order to be able to remove the releasable trough of the fill pipe transversely with respect to the transport direction from the forming shoulder.
