Abstract

The invention relates to a filter (1) for a smoking article, a method of production thereof, a smoking article and a device for inserting a first fibrous filter material (3) into a second fibrous filter material (4) to form a filter for a smoking article. Particularly but not exclusively the invention relates to a smoking article filter segment including a region of first fibrous filter material (3) disposed within a region of second fibrous filter material (4) and a method of production thereof. The first fibrous filter material (3) in some embodiments comprises greater than 5% by volume of the total filter segment volume and in some embodiments the first fibrous material comprises PLA fibres and the second fibrous filter material comprises CA fibres.

Claims

AMENDED CLAIMS received by the International Bureau on 04 February 2014 (04.02.2014)
1. A filter segment for a smoking article, the filter segment comprising a region of first fibrous filter material disposed at least substantially within a region of second fibrous filter material, wherein the first fibrous filter material comprises greater than 5% by volume of the total filter segment volume.
2. A filter segment according to claim i, wherein the first fibrous filter material is disposed in a plurality of regions of the filter segment.
3. A filter segment according to claim 2, wherein the plurality of regions can each comprise greater than 396 of the total filter segment volume.
4. A filter segment according to claim l, a or 3, wherein the second fibrous filter material is a plasticised filter material and wherein the first fibrous filter material is a non-plaaticised filter material.
5. A filter segment according to any preceding claim, wherein the first and second fibrous filter materials comprise crimped fibres.
6. A filter segment according to any preceding claim, wherein the first fibrous filter material comprises polylactide (PLA) fibres and/or the second fibrous filter material comprises cellulose acetate fibres.
7. A filter segment according to any preceding claim, wherein the first fibrous filter material comprises from 5 to 60% by volume of the total filter segment volume,
8. A filter segment according to any preceding claim, wherein the first fibrous filter material comprises from 10 to 60% by volume of the total filter segment volume.
9. A filter segment according to any preceding claim, wherein the first fibrous filter material comprises from 200 to 10,000 fibres having a denier from 2 to 10 denier per filament.
10. A filter segment according to any preceding claim, wherein the region of first fibrous filter material comprises a region extending longitudinally through the region of second fibrous filter material.
11. A filter segment for a smoking article, the filter segment comprising a region of first fibrous material disposed at least substantially within a region of second fibrous material, wherein the first fibrous material comprises polylactide (PLA.) fibres.
12. A filter segment according to claim n, wherein the second fibrous material comprises cellulose acetate (CA) fibres.
13. A smoking article comprising a filter segment according to any one of the preceding claims.
14. A method of producing a filter segment for a smoking article, the method comprising:
feeding a supply of a first fibrous filter material into a second fibrous filter material to form a filter segment according to any one of claims 1 to 12.
15. A method according to claim 14, further comprising applying a plasticiser to said second fibrous filter material prior to feeding the supply of the first fibrous material into the second fibrous filter material.
16. A method according to claim 14 or 15, further comprising crimping said first and second fibrous filter materials prior to feeding the supply of the first fibrous material into the second fibrous filter material.
17. A method according to claim 14, 15 or 16, further comprising compressing said second fibrous filter material to form a filter rod and feeding the supply of the first fibrous filter material into the second fibrous filter material while compressing the second fibrous filter material to form the filter rod.
18. A method according to claim 17, wherein the first fibrous filter material is fed into the second fibrous filter material in a tongue section of a filter making apparatus.
19. A method according to any one of claims 14 to 18, wherein the first fibrous filter material comprises a thread of first fibrous filter material.
20. A method of producing a filter for a smoking article, the method comprising: generating a fluid stream; and
transferring a first fibrous material along a transfer path into a flow of a second fibrous filter material using the fluid stream.
21. A method according to claim 20, wherein said fluid stream is generated using air pressure.
22. A method according to claim 20 or 21, wherein the first fibrous filter material is transfetred into the flow of the second fibrous filter material in a tongue or stuffer jet section of a filter malting apparatus.
23. A device for inserting a first fibrous filter material into a second fibrous filter material to form a filter for a smoking article, the device comprising a pressure generator to generate a fluid stream for carrying said first fibrous material along a transfer path into a flow of said second fibrous filter material.
