  • the aligned to the firing channel 7 surface of the opening shell 85 here has three air nozzles 12, 87 and 88 which are positioned differently far from the outlet opening 13 and different distances from the central axis to to achieve an optimal opening of the bag valve.
  • Each air nozzle 12, 87 and 88 may be associated with a respective channel 89, 91 and 92.
  • the invention provides an advantageous device and an advantageous method, which also valve bags 2 made of flexible materials with high speed and reliable can be plugged onto the filler neck 3 of rotating or stationary packaging machines.
  • a reliable alignment of the valve bags 2 takes place on the delivery table 34 in order to ensure a defined receiving the valve bags 2.
  • the valve bags 2 are aligned repeatably in the vertical direction and it is carried out by the air flow in the valve port 31, a reliable opening of the bag valves 8 of the valve bags. 2
  • air is understood to mean not only air but also any other gas or gas mixture.
  • air nozzle basically includes any gas outlet elements and gas outlet surfaces. Are possible round, square, oval, rounded, flat and other cross-sectional shapes on the gas outlet surface. It is also possible, for example, that a Rohroder hose is used as a gas outlet. The design does not have to be nozzle-shaped in the narrower sense. Also, an end of a pipe or hose without cross-sectional change is considered as an air nozzle in the context of the present invention.
