Abstract
The invention relates to a sealing station in a film bag filling device for sealing of film bags after a filling process, wherein the sealing station comprises a first and a second sealing arm for sealing of several filled film bags that are arranged next to one another, wherein the first sealing arm is moveable with a first drive shaft and the second sealing arm with a second drive shaft. A servo engine is disposed on the first drive shaft, and a drive movement of the first drive shaft from a first gear wheel is transferred to a second gear wheel that encroaches in the first gear wheel and from the second gear wheel to the second drive shaft. The invention further relates to a method for sealing of film bags after a filling process with the sealing station according to the invention with the following steps: positioning of filled film bags below the sealing station; closing of the sealing arms and application of a contact pressure with a first value and sealing of the filled film bags.
