Abstract (en)
[origin: US2019382147A1] A method for operating a sealing station of a packaging machine, wherein the method may include one or more of the following steps: filling a packing volume of a package with a gas to create a desired atmosphere to a preset gassing target pressure for a finished package, wherein the packaging volume may be defined by a lower and an upper packaging material; discharging a partial amount of the gas introduced into the packaging volume from the packaging volume into a collection volume while retaining the packaging volume generated by the preceding filling, which reduces the pressure within the packaging volume; and reducing the packaging volume by moving the upper packaging material to an end position that corresponds to a desired appearance such that the pressure inside the package increases again to near the gassing target pressure. A sealing station that performs this method is also described.
