Concentric to the annular groove 26 is in inner cylinder 20 a recess 28 is provided in which the cylindrical part 9 of the mouthpiece 4 is immersed.

Ist der Füllkopf 14 auf das Mundstück 4 aufgesetzt, dient das in der Ringnut 26 erzeugte Vakuum zur Vereinigung von Füllkopf 14 und Beutel 1. Zu dieser Vereinigung können auch Saugnäpfe dienen, die elastisch an der Halterung 15 angesetzt sind und den Beutel seitlich des Füllkopfes 14 beaufschlagen. If the filling head 14 is placed on the mouthpiece 4, it is used the vacuum generated in the annular groove 26 for the union of the filling head 14 and the bag 1. This union can also Suction cups are used, which are attached elastically to the holder 15 and act on the bag at the side of the filling head 14.

Druckluft wird in den inneren Zylinder 20 über die Leitung 23 eingeführt, so daß der Kolben 24 und damit das Einfüllrohr 13 gegen das Mündstück 4 verstellt wird. Das Einfüllrohr 13 durchsticht mittels seines angeschrägten Endes die Verschlußwand 11 und dringt in den Beutel 1 ein. Es wird nun das Ventil 24 geöffnet und das Produkt gelangt in den Beutel 1 über die Leitung 25 und das Einfüllrohr 13, wie aus Fig. ersichtlich.Compressed air is introduced into the inner cylinder 20 via the line 23, so that the piston 24 and thus the filler tube 13 is adjusted against the mouthpiece 4. The filler pipe 13 pierces the closure wall 11 by means of its beveled end and penetrates the bag 1. It will now the valve 24 is opened and the product enters the bag 1 via the line 25 and the filler pipe 13, as shown in FIG. evident.

Nach Beendigung des Füllvorganges wird das Ventil 24 geschlossen und die Leitung 23 wird an die Außenluft über ein nicht dargestelltes Ventil angeschlossen, so daß die Rückholfeder die Rückstellung des Einfüllrohres 13 bewirkt, welches sich vom Mundstück 4 absetzt.After completion of the filling process, the valve 24 is closed and the line 23 is over to the outside air connected a valve, not shown, so that the return spring causes the return of the filler pipe 13, which separates from the mouthpiece 4.

Nun erfolgt der Verschluß des Beutels 1, welcher wie folgt abläuft:Now the closure of the bag 1 takes place as follows expires:
