A method for reducing restoring forces of package sleeves in a filling machine, wherein each flat-folded package sleeve comprises four package walls (5a, b, 6a, b) separated from one another by parallel-running outer (3a, b) and inner (4a, b) fold edges and at the outer fold edges (3a, b) respectively one acute internal angle is enclosed between the package walls (5a, b, 6a, b), comprising the process steps - inserting flat-folded package sleeves into a magazine of the filling machine, - removing respectively one flat-folded package sleeve from the magazine and unfolding the flat-folded package sleeve to form an upright package sleeve forming a parallelogram in cross-section by means of a removal and unfolding apparatus and - transferring the upright package sleeve by means of a transfer apparatus to a transport device downstream of the removal and unfolding apparatus for transporting the upright package sleeve along a transport path, wherein at least one processing step is carried out on the upright package sleeve whilst the upright package sleeve is located on the transport path of the transport device characterised by - the transfer of the upright package sleeve to a transport device, which comprises a transport wheel having a plurality of radially outwardly extended receptacles for respectively one package sleeve, wherein each receptacle has a plurality of profiles (30, 31, 40, 42) which can be brought to rest against and/or adjacent to the fold edges (3a, b) of the package sleeve and wherein the transport device has a drive for turning the transport wheel about an axis of rotation, - reducing the restoring force by temporarily increasing the internal angle between the package walls (5a, b, 6a, b) at the outer fold edges (3a, b) to more than 90° whilst the upright package sleeve is located on the transport path of the transport device, - wherein the transport device is operated in a stepwise manner and that the reduction in the restoring force is accomplished during a standstill of the upright package sleeve on the transport path or during a movement of the upright package sleeve along the transport path. - inserting flat-folded package sleeves into a magazine of the filling machine, - removing respectively one flat-folded package sleeve from the magazine and unfolding the flat-folded package sleeve to form an upright package sleeve forming a parallelogram in cross-section by means of a removal and unfolding apparatus and - transferring the upright package sleeve by means of a transfer apparatus to a transport device downstream of the removal and unfolding apparatus for transporting the upright package sleeve along a transport path, wherein at least one processing step is carried out on the upright package sleeve whilst the upright package sleeve is located on the transport path of the transport device - the transfer of the upright package sleeve to a transport device, which comprises a transport wheel having a plurality of radially outwardly extended receptacles for respectively one package sleeve, wherein each receptacle has a plurality of profiles (30, 31, 40, 42) which can be brought to rest against and/or adjacent to the fold edges (3a, b) of the package sleeve and wherein the transport device has a drive for turning the transport wheel about an axis of rotation, - reducing the restoring force by temporarily increasing the internal angle between the package walls (5a, b, 6a, b) at the outer fold edges (3a, b) to more than 90° whilst the upright package sleeve is located on the transport path of the transport device, - wherein the transport device is operated in a stepwise manner and that the reduction in the restoring force is accomplished during a standstill of the upright package sleeve on the transport path or during a movement of the upright package sleeve along the transport path.
