  • 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.

Abstract

L'invention concerne un dispositif de remplissage destiné à remplir des récipients (12a-d) avec des substances liquides et/ou pâteuses, notamment pour une emballeuse (14a ; 14d), comprenant un dispositif de dosage (26a-d) qui possède au moins une pompe doseuse (16a-d) ayant au moins une cylindrée de dosage (18a-d) ayant un volume de cylindrée (24a-d) qui peut être modifié par un piston de dosage (20a-d) dans une course du piston. Selon l'invention, une cylindrée globale 28a-d) du dispositif de dosage (26a-d) qui englobe toutes les cylindrées de dosage (18a-d) correspond au moins à un multiple d'un volume de remplissage à délivrer à au moins un récipient (12a-d) dans une opération de dosage.
