  • a here only indicated material web 56 d is deflected in the direction of gravity, transported in a feed direction 58 d down and cut by three not shown here cutting knife in the feed direction 58 d so that the material web 56 d forms four equal width partial webs, each one of Filling devices 10d are supplied.
  • a movement in the feed direction 58d forms a container feed 48d of the packaging machine 14d.
  • a film tube 60d is formed in each case.
  • the respective partial web of the web of material 56d is turned over by a forming shoulder (not illustrated here) and a metering tube 62d of the respective filling unit 34d.
  • a longitudinal sealing unit 64d seals the two layers of material lying on each other by folding over the partial web of the material web 56d, using pressure and heat, to form the film tube 60d.
  • a transverse sealing unit 68d In the feed direction 58d below the longitudinal sealing unit 64d is a transverse sealing unit 68d.
  • the transverse sealing unit 68d forms in each case a transverse sealing seam 72d, which forms a container bottom 50d of the respective container 12d.
  • the container feed 48d is clocked, ie the movement in the feed direction 58d is stopped briefly when attaching the transverse sealing seam 72d.
  • the transverse sealing unit 68d simultaneously forms a transverse sealing seam 72d forming the container bottom 50d of the respective container 12d to be filled, as well as a further transverse sealing seam closing the container 12d in the feed direction 58d.
  • the transverse sealing unit 68d here has transverse knives not shown in greater detail, which cause the containers 12d following in the feed direction 58d to be separated from the film tube 60d when forming the transverse sealing seams 72d.
  • the other functions of the packaging machine 14d and the filling device 10d correspond to the packaging machine 14a and the filling device 10a of the first embodiment.
