Abstract: The present invention relates to a packing machine for packing articles (4) in a film (5), with a tube shaping device (1) for shaping a tube from a film which is substantially flat prior to tube shaping and a transporting device (2) for transporting the articles into the tube, the tube shaping device having several pairs of shaping edges (12, 17, 18) for deflecting or reversing the film. The packing machine is characterized in that the shaping edges (12, 17, 18) are positioned relative to one another in such a way that the path over the shaping edges along lines parallel to the borders (11) of the film (5) from an entrance of the film into the tube shaping device (1) up to its exit therefrom, is shorter in the vicinity of the film borders than in a central region of the film.
