Abstract
A method for reducing restoring forces of package sleeves in a filling machine, where flat-folded package sleeves are removed from a magazine of the filling machine, erected to form a package sleeve forming a parallelogram in cross-section and then transferred to a transport device for transporting the upright package sleeve along a transport path. In order to enable a reduction in the restoring force adapted to the particular material of the package sleeve without increasing the cycle time for the removal and unfolding of the flat-folded package sleeve, the restoring force is reduced by temporarily increasing the internal angle between the package walls at the outer fold edges to more than 90° while the upright package sleeve is located on the transport path of the transport device. The reduction of the restoring force can be accomplished during the movement or during a standstill of the package sleeve on the transport path.
