In order to achieve in a vertical tubular bagging machine ( 1 ) an even foil path precise in location, a foil-removing system is suggested, which provides for a secure introduction of the edges ( 29 ) of a foil web ( 3 ) into a longitudinal sealing device ( 7 ) in order to weld a foil tube ( 5 ) in its transport direction ( 8 ). The foil-removing system has rollers ( 10 ) driven by a drive ( 12 ), which rollers, viewed in transport direction ( 8 ), are provided between the forming shoulder ( 4 ) and the longitudinal sealing device ( 7 ), and an additional foil-removing means ( 19 ) with a drive ( 20 ) and a belt ( 22 ) rotating around two wheels ( 21 ), which belt acts against the foil tube ( 5 ) and thus against the fill pipe ( 6 ), and which acts at a point of the foil tube ( 5 ) where the longitudinal seam ( 9 ) is not. The two drives ( 12, 20 ) are synchronized with one another.
