Abstract

The invention relates to a packaging apparatus (1) and a method used to produce packaging units (35). The packaging units (35) comprise at least one article (30), such as a beverage can (31), held in a packaging blank (20) having at least in some portions or areas that are flat. The packaging blank (20) has at least one passage opening (23) in the flat portion or area for article(s) (30). The packaging apparatus (1) comprises a feeder device (2); a pre-treatment module (9) to prepare the packaging blank (20) for the application to the article(s) (30); and a first packaging module (7) to apply and locate the packaging blank (20) to the article(s) (30). The pre-treatment module (9) comprises a device to reduce a resistance force in an edge area (24) of the passage openings (23) during the application of the packaging blank (20) to the article(s) (30).

a magazine ( 8 ) holding a stack of packaging blanks ( 20 );
a gripper ( 13 ) that transfers at least one packaging blank ( 20 ) from the magazine ( 8 ) to the pre-treatment module ( 9 ), where the gripper ( 13 ) presses the at least one packaging blank ( 20 ) on to the at least one die of the at least one resistance reducing device in order to reduce a resistance force in an edge area ( 24 ) of the at least one passage opening ( 23 ) of the packaging blank ( 20 ).

2. The packaging apparatus ( 1 ) of claim 1 , wherein:
the at least one feeder device ( 2 ) is for at least two articles ( 30 ) or is for an assembly ( 40 ) of at least two articles ( 30 );
the pre-treatment module ( 9 ) is to prepare a packaging blank ( 20 ) for application to the at least two articles ( 30 ) or assembly ( 40 );
the first packaging module ( 7 ) is to apply and locate the packaging blank ( 20 ) to the at least two articles ( 30 ) or assembly ( 40 );
wherein the pre-treatment module ( 9 ) comprises at least one resistance reducing device designed to reduce a resistance force in an edge area ( 24 ) of the passage openings ( 23 ) of the packaging blank ( 20 ) for the at least two articles ( 30 ) or assembly ( 40 ).

3. The packaging apparatus of ( 1 ) of claim 2 , wherein the resistance reducing device of the pre-treatment module ( 9 ) comprises at least one stretching device, at least one cutting device, at least one perforating device, at least one moistening device, or at least one heating device.

4. The packaging apparatus ( 1 ) of claim 3 , wherein the resistance reducing device comprised a plurality of stretching dies ( 18 ), and wherein the plurality of stretching dies ( 18 ) are arrangeable in different arrangements or numbers in the pre-treatment module ( 9 ).

5. The packaging apparatus of ( 1 ) of claim 1 , wherein the resistance reducing device of the pre-treatment module ( 9 ) comprises at least one stretching device, at least one cutting device, at least one perforating device, at least one moistening device, or at least one heating device.

6. The packaging apparatus ( 1 ) of claim 5 , wherein the resistance reducing device comprises at least one stretching die ( 18 ).

7. The packaging apparatus ( 1 ) of claim 6 , wherein the at least one stretching die ( 18 ) is arranged in a detachable manner in the pre-treatment module ( 9 ).

8. The packaging apparatus ( 1 ) of claim 7 , wherein the resistance reducing device comprises a plurality of stretching dies ( 18 ), and wherein the plurality of stretching dies ( 18 ) are arrangeable in different arrangements or numbers in the pre-treatment module ( 9 ).

9. The packaging apparatus ( 1 ) of claim 8 , wherein the number and arrangement of the stretching dies ( 18 ) correspond to the number and arrangement of the passage openings ( 23 ) of the packaging blank ( 20 ), and wherein the packaging blank ( 20 ) is pressed onto the stretching dies ( 18 ) in such a manner that the at least one stretching die ( 18 ) passes through the at least one passage opening ( 23 ) at least in some areas.

10. The packaging apparatus ( 1 ) of claim 5 , wherein the resistance reducing device comprises at least one cutting device or at least one perforating device.

11. The packaging apparatus ( 1 ) of claim 5 , wherein the resistance reducing device comprises at least one moistening device or wherein the resistance reducing device comprises at least one heating device ( 18 ).

12. A packaging apparatus ( 1 ) used to produce packaging units ( 35 ) comprising:
at least one feeder device ( 2 ) for the at least one article ( 30 ) or for an assembly ( 40 ) of at least two articles ( 30 );
a pre-treatment module ( 9 ) comprising at least one resistance reducing device designed to reduce a resistance force in an edge area ( 24 ) of at least one passage opening ( 23 ) of a packaging blank ( 20 ) and wherein the at least one resistance reducing device is capable of enlarging an average diameter (d 23 ) of the at least one passage opening ( 23 ), the pre-treatment module ( 9 ) used to prepare the packaging blank ( 20 ) for application to the at least one article ( 30 ) or assembly ( 40 ), wherein the packaging blank ( 20 ) comprises at least some portion that is flat and the at least one passage opening ( 23 ) is in the flat portion;
a first packaging module ( 7 ) to apply and locate the packaging blank ( 20 ) to the at least one article ( 30 ) or assembly ( 40 );
a magazine ( 8 ) holding a stack of packaging blanks ( 20 );
a gripper ( 13 ) that transfers at least one packaging blank ( 20 ) from the magazine ( 8 ) to the pre-treatment module ( 9 ), where the gripper ( 13 ) presses the at least one packaging blank ( 20 ) on to the at least one die of the least one resistance reducing device in order to enlarge an average diameter (d 23 ) of the at least one passage opening ( 23 ).

13. A packaging apparatus ( 1 ) used to produce packaging units ( 35 ) comprising:
