Abstract

A tobacco cut filler comprises a first tobacco material cut in accordance with a first cut specification, wherein the first cut specification sets at least predetermined first cut width and first cut length.

First claim

The invention claimed is:

1. A tobacco cut filler comprising a first tobacco material cut into strips in accordance with a first cut specification, wherein the first cut specification sets at least predetermined first cut width and first cut length corresponding to a final cut width and a final cut length in the tobacco cut filler when used in a tobacco product, wherein a cut length distribution among the cut strips of the first tobacco material is at least bimodal.

2. A tobacco cut filler according to claim 1 , further comprising a second tobacco material cut in accordance with a second cut specification differing from the first cut specification for at least one of cut length and cut width.

3. A tobacco cut filler according to claim 1 , wherein the first tobacco material is a pre-processed tobacco material.

4. A tobacco cut filler according to claim 1 , wherein the first tobacco material is a reconstituted tobacco sheet.

5. A tobacco cut filler according to claim 2 , wherein the second tobacco material is a natural tobacco leaf material.

6. A tobacco cut filler according to claim 1 , wherein the first tobacco material is shredded into strips having a cut length from about 5 mm to about 60 mm.

7. A tobacco cut filler according to claim 1 , wherein the cut length distribution among the cut strips of the first tobacco material is trimodal.

8. A tobacco cut filler according to claim 1 , wherein the first tobacco material is shredded into strips having a cut width from about 0.2 mm to about 1 mm.

9. A tobacco cut filler according to claim 1 , wherein the first tobacco material is shredded into strips from a sheet material having a thickness from about 0.05 mm to about 1 mm.

10. A tobacco cut filler according to claim 1 , wherein the first tobacco material is shredded into strips having a sinusoidal shape, wherein a wave length of the sinusoidal shape is from about 1 mm to about 15 mm.

11. A tobacco cut filler according to claim 1 , wherein the first tobacco material is shredded into strips each comprising at least a first strip structure comprising a branching node from which a further strip structure branches off, forming an angle with the first strip structure.

12. A tobacco cut filler according to claim 1 , wherein the first tobacco material is shredded into strips each comprising at least a first, a second and a third strip structures, wherein the first strip structure comprises a node from which the second strip structure branches off, the second strip structure comprises a second node from which the third strip structure branches off.

13. A tobacco cut filler according to claim 1 having a filling power of at least 3.5 cubic centimetres per gram at a reference moisture value of 12.5 percent oven volatiles.

14. A smoking article comprising a rod of a tobacco cut filler according to claim 1 .

15. A method of making tobacco cut filler comprising:
providing a first tobacco material;
cutting the first tobacco material into strips in accordance with a first cut specification setting at least predetermined first cut width and first cut length, a cut length distribution among the cut strips being at least bimodal.

16. A method according to claim 15 , comprising:
providing a second tobacco material;
cutting the second tobacco material separately from the first tobacco material and in accordance with a second cut specification, the second cut specification differing from the first cut specification for at least one of cut length and cut width; and
blending the cut first tobacco material and the cut second tobacco material.

17. A method according to claim 15 , wherein the first tobacco material is a pre-processed tobacco material.

18. A method according to claim 15 , wherein the second tobacco material is a reconstituted tobacco sheet.

19. A method according to claim 15 , further comprising conditioning the first tobacco material prior to cutting the first tobacco material.

20. A method according to claim 18 , comprising controlling the moisture content of the cut filler by adjusting the moisture content of the first tobacco material.

21. A method according to claim 15 , further comprising adjusting the moisture content of the second tobacco material.
