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 from 0.9 mm to 1 mm and first cut length from 20 mm to 40 mm for the strips corresponding to a final cut width and a final cut length of the strips in the tobacco cut filler when used in a tobacco product, a cut length distribution among the cut strips being unimodal, wherein the first tobacco material is a reconstituted tobacco sheet having a thickness from 0.05 mm to 1 mm, the tobacco cut filler 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.

2. The tobacco cut filler according to claim 1 , wherein the second tobacco material is a natural tobacco leaf material.

3. The 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.

4. The 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.

5. The 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, and wherein the second strip structure comprises a second node from which the third strip structure branches off.

6. The 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.

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

8. 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 from 0.9 mm to 1 mm and first cut length from 20 mm to 40 mm for the strips corresponding to a final cut width and a final cut length in the tobacco cut filler when used in a tobacco product, a cut length distribution among the cut strips being unimodal, wherein the first tobacco material is a reconstituted tobacco sheet having a thickness from 0.05 mm to 1 mm;
providing a second tobacco material;
cutting the second tobacco material separately from the first tobacco material and in accordance with a 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 to form the tobacco cut filler.

9. A method according to claim 8 , further comprising conditioning the first tobacco material prior to cutting the first tobacco material.

10. A method according to claim 9 , comprising controlling a moisture content of the cut filler by adjusting a moisture content of the first tobacco material.

11. A method according to claim 8 , further comprising adjusting a moisture content of the second tobacco material.
