Abstract

The invention relates to an inflating station for inflating of film bags with a first and a second suction bar arm and with an inflating bar with inflating spouts arranged on it. The first/second suction bar arm is movable with a first/second drive shaft. A servo engine is disposed on the first drive shaft. A drive movement of the first drive shaft is transferred from a first gear wheel to a second gear wheel and from the second gear wheel to the second drive shaft. Further, the invention relates to a method for inflating of film bags with this inflating station with the steps: positioning of the film bags below the inflating station; closing of the suction bar arms and application of a first contact pressure; horizontal displacement of the vacuum cups in a first direction, establishment of the contact with the film bag halves, formation of a negative pressure; horizontal displacement of the vacuum cups in a second direction, therefore opening of the film bags; inserting of the inflating spouts in the film bags; increasing of the contact pressure to a second value and subsequent inflating of the film bags by means of the inserted inflating spouts.
