Claims

1. Apparatus for packaging tobacco industry products, the apparatus defining a path and comprising a plurality of carriers configured to move along the path, each carrier being adapted to carry a group of tobacco industry products and a wrapper; the apparatus further comprising:

a sealing station located at a position on the path and configured to seal the wrapper about the group of tobacco industry products to form a sealed bundle of tobacco industry products; and

a process station located at a position on the path and configured to extract gaseous fluid from and/or input gaseous fluid into the sealed bundle of tobacco industry products.

2. The apparatus of claim l, wherein the path is a closed loop.

3. The apparatus of claim l or claim 2, wherein the carriers move in only a single direction along the path.

4. The apparatus of any of claims l to 3, further comprising an electromagnetic drive system configured to move the carriers along the path.

5. The apparatus of any one of the claims 1 to 4, further comprising a control system configured to control movement of the carriers along the path such that the relative spacing between adjacent carriers is alterable.

6. The apparatus of any of claims 1 to 5, wherein the sealing station comprises a first sealer arranged to form a first seal in the wrapper, and a second sealer arranged to form a pair of second seals in the wrapper, each of the second seals being perpendicular to the first seal, and wherein the second sealer is located downstream of the first sealer along the path.

7. The apparatus of claim 6, wherein each of the first sealer and the second sealer comprises sealer bars configured to form the first and second seals, respectively.

8. The apparatus of claim 7, wherein the second sealer comprises two pairs of sealer bars.

9. The apparatus of claim 7 or claim 8, wherein the sealer bars of the first sealer and the sealer bars of the second sealer are arranged parallel to the path in the position on the path where the first sealer and second sealer are located.

10. The apparatus of any of claims 6 to 9, comprising a rotation mechanism configured to rotate the group of tobacco industry products and wrapper after the first seal has been formed.

11. The apparatus of any of claims 6 to 10, wherein the first sealer and/ or the second sealer is configured to form seals in a plurality of wrappers simultaneously.

12. The apparatus of any of claims 1 to 11, wherein the process station comprises a pipe configured to extract gaseous fluid from and/or input gaseous fluid into the sealed bundle of tobacco industry products via an opening in the sealed bundle of tobacco industry products.

13. The apparatus of any of claims 1 to 12, wherein the apparatus further comprises at least one track, wherein the path is defined by the at least one track, and wherein each carrier comprises a track engagement portion adapted to movably engage with the track, and a retainer adapted to retain the group of tobacco industry products and wrapper.

14. The apparatus of claim 13, wherein each track engagement portion comprises one or more rollers arranged to roll along the track during use.

15. The apparatus of claim 13 or claim 14, wherein each retainer comprises spaced walls that define a space therebetween, the space being adapted to receive and carry the group of tobacco industry products and wrapper.

16. The apparatus of claim 15, wherein each retainer is configured such that ends of the wrapper protrude from the space when the group of tobacco industry products and wrapper are received in the pocket such that the ends of the wrapper can be sealed by the sealing station.

17. The apparatus of any of claims 13 to 16, wherein each retainer comprises a first holder part adapted to hold a first end of the group of tobacco industry products and wrapper.

18. The apparatus of claim 17, wherein each retainer further comprises a second holder part adapted to hold a second end of the group of tobacco industry products and wrapper, the second holder part being arranged on an opposite side of the retainer to the first holder part.

19. The apparatus of claim 18, wherein the second holder part is removably attachable to the carrier.

20. The apparatus of claim 18, wherein the second holder part is pivotally attached to the carrier.

21. The apparatus of any of claims 13 to 20, wherein each retainer is removably attachable to the track engagement portion.

22. The apparatus of claim 21, wherein each retainer is magnetically attachable to the track engagement portion.

23. The apparatus of claim 21, wherein each carrier comprises a mechanical clip for removably attaching the retainer to the track engagement portion.

24. The apparatus of any of claim 21 to claim 23, wherein each retainer further comprises an alignment device for aligning the retainer relative to the track

engagement portion.

25. The apparatus of any preceding claim, further comprising a loading station configured to load a group of tobacco industry products and/ or a wrapper onto one of the carriers.

26. The apparatus of claim 25, wherein the loading station comprises a pusher arranged to push a group of tobacco industry products onto the one of the carriers.

27. The apparatus of claim 26, wherein the loading station is configured to position a wrapper between a group of tobacco industry products and the carrier prior to loading the group of tobacco industry products onto the carrier, such that the wrapper is at least partially wrapped about the group of tobacco industry products as the group of tobacco industry products is loaded onto the carrier.

28. The apparatus of any of claims 1 to 27, further comprising an unloading station configured to remove the sealed bundle of tobacco industry products from the carrier.

29. A method of packaging tobacco industry products, the method comprising: carrying groups of tobacco industry products and wrappers on a plurality of carriers that move along a path;

sealing the wrapper about the group of tobacco industry products to form a sealed bundle of tobacco industry products; and,

extracting gaseous fluid from and/or inputting gaseous fluid into the sealed bundle of tobacco industry products.

30. The method of claim 29, wherein the path is a closed loop.

31. The method of claim 30, wherein the carriers move in only a single direction along the path.

32. The method of claim 31, wherein the carriers are moved along the track by an electromagnetic drive system.

33. The method of any of claims 29 to 32, further comprising controlling movement of the carriers along the path such that the relative spacing between adjacent carriers is alterable.
