Die Wirkungsweise ist folgende: Sobald die Folie 10 durch die Vorzugswalzen 11 und 12 absatzweise vorgeschoben ist, wobei durch den aus dem austretenden Luftstrom auch eine Ausrichtung erfolgt, wird der Schweißbalken 18 in angegebener Pfeilrichtung 55 nach links bewegt. Er führt eine Trenn-Schweißung durch, so daß der Beutel von dem Folienschlauch getrennt wird, Anschließend wird die Andrückleiste 25 nach links bewegt und zugleich mit dieser Bewegung führt auch der Rechen 52 eine Bewegung nach links durch, wobei er zugleich angehoben wird. Mit der Bewegung der Andrückleiste 25 in angegebener Pfeilrichtung 35 drückt diese Leiste 25 die Beutelklemmleiste 22 entgegen dem Druck der Schraubenlinienfedern 24 nach links. Durch den Rechen 52 wird das obere Ende des Beutels hinter den Balken 21 gebracht. Mit dem Zurückgehen derAndrückleiste 25 wandert die Beutelklemmleiste 22 wieder nach rechts, so daß der Beutel zwischen dem Balken 21 und der Beutelklemmleiste 22 festgeklemmt wird. Sofern zugleich mit dem Bilden des Stapels der nachfolgende Beutel mit jeweils vorhergehenden Beuteln verschweißt werden soll, dann geschieht dies durch das elektrisch erhitzte Impulsband 54. Dieses kann ständig, braucht aber nicht, sofern keine Verschweißung der Beutel des Stapels untereinander erfolgen soll, eingeschaltet zu sein.The mode of operation is as follows: As soon as the film 10 has passed through the feed rollers 11 and 12 is advanced intermittently, with by the exiting air flow an alignment also takes place, the sealing bar 18 is in the indicated arrow direction 55 moved to the left. He performs a separation weld, so that the bag of the film tube is separated, then the pressure strip 25 is to the left moves and at the same time with this movement the rake 52 also follows a movement to the left, lifting it at the same time. With the movement of the pressure bar 25 in the indicated arrow direction 35, this bar 25 presses the bag clamping bar 22 against the pressure of the helical springs 24 to the left. By the rake 52 the upper end of the bag is brought behind the beam 21. With going back the pressure strip 25 moves the bag clamping strip 22 back to the right, so that the bag is clamped between the beam 21 and the bag clamping strip 22. Provided that at the same time as the stack is formed, the subsequent bag with the previous one Bags are to be welded, then this is done by the electrically heated Pulse band 54. This can be continuous, but does not need to be, provided there is no welding the bags of the stack below each other should be switched on.

Die Andrückleiste 25 ist als Vakuumleiste ausgebildet, um eine bessere Erfassung der einzelnen Beutel zu erreichen.The pressure strip 25 is designed as a vacuum strip to provide a better To achieve capture of the individual bags.

Fig. 2 zeigt die Abwandlung, daß die Beutelklemmleiste 22 mit Stiften 40 versehen ist. Vorzugsweise finden zwei oder drei nebeneinander angeordnete Stifte Anwendung. Diese Stifte sind gelagert in einer Leiste 56, wobei diese Leiste 56 durch den Druck von Federn 57 gegen einen Nocken 58 der Welle 39 gedrückt wird. Durch die Drehung des Nockens 58 ist das Maß einstellbar, um das die Stifte 40 über die Klemmfläche 25 in Gestalt einer Gummieinlage vorstehen.Fig. 2 shows the modification that the bag clamping strip 22 with pins 40 is provided. Preferably there are two or three pegs arranged next to each other Use. These pins are stored in a bar 56, this bar 56 is pressed against a cam 58 of the shaft 39 by the pressure of springs 57. By rotating the cam 58, the amount by which the pins 40 over can be adjusted the clamping surface 25 protrude in the form of a rubber insert.

Die Andrückleiste 25 ist prinzipiell in gleicher Weise, wie in Fig. 1 beschrieben, als Vakuumleiste ausgebildet bzw. kann als solche ausgebildet sein.The pressure strip 25 is in principle in the same way as in Fig. 1, designed as a vacuum strip or can be designed as such.

Nach dem Abtrennen der einzelnen Beutel vom Schlauch wird durch die Bewegung der Andrückleiste 25 in angegebener Pfeilrichtung 55 der Beutel auf den Stiften 40 aufgeschlagen und von diesem gehalten. Sofern zugleich mit dem Stapeln der Beutel deren Verschweißung untereinander erfolgen soll, dann dient dazu das an der Andrückleiste 25 angeordnete elektrische Impulsband 54, das in Fig. 1 an dem Balken 21 angeordnet ist.After the individual bags have been separated from the tube, the Movement of the pressure bar 25 in the indicated arrow direction 55 of the bag on the Opened pins 40 and held by this. If at the same time as stacking the bag which is to be welded together, then this is used on the pressure strip 25 arranged electrical pulse band 54, which in FIG the bar 21 is arranged.

Fig. 2 zeigt noch in gleicher Weise wie in Fig. 1, daß an der Beutelklemmleiste 22 ein Anschlag'41 vorhanden ist, der mit dem weiteren Anschlag 42 zusammenwirkt, um das Maß der Bewegung der Beutelklemmleiste 22 in Richtung nach rechts zu beschränken.Fig. 2 shows in the same way as in Fig. 1 that on the bag clamping strip 22 there is a stop 41 which interacts with the further stop 42, to limit the amount of movement of the bag clamping bar 22 in the rightward direction.
