Even extra ideally, first tobacco materials is shredded into strips having a cut length of at least about 15 mm. In addition, or in its place, the primary tobacco materials is ideally shredded into strips having a cut length of less than about 60 mm. More preferably, the first tobacco material is shredded into strips having a reduce length of lower than about 50 mm. Even extra ideally, the first tobacco material is shredded into strips having a minimize length of lower than about forty mm. In most popular embodiments, the first tobacco material is shredded into strips having a minimize size from about 5 mm to about 60 mm. The time period “sectional cut width” is used within the current specification to explain the side- to-side width of 1 such portion of a cut strip of tobacco material.
Preferably, the primary tobacco material is shredded into strips whereby the cut size is greater than the minimize width. Further, when reconstituted tobacco undergoes the same treatments as tobacco lamina, a big amount of tobacco mud is shaped. Besides, within the curiosity of course of economy, it’s desirable that the tobacco mud be reprocessed in some kind or other to extend the general effectivity.
The yield of flat rolled stem which can be used directly as filler is increased, and the common stem size and thus the average length of minimize filler from stem is increased. A tobacco cut filler based on any one of the preceding claims having a filling power of no much less than three.5 cubic centimetres per gram at a reference moisture worth of 12.5 % oven volatiles. Accordingly, tobacco particles had been ready from the identical sheet of reconstituted tobacco in accordance with the cut specification illustrated in Figure 12, wherein the minimize width SCW1 is of zero.9 millimetres, the cut length CL1 is of 4.94 millimetres and the worldwide width CW1 is of 12.50 millimetres.
Should one such particle break at a location in the central V-shaped portion, the two ensuing elements of the particles would still be successfully V-shaped. The highest CCV values had been obtained for cut specification no. 3, which substantially corresponds to particles having a Y-shape. However, it was found that when particles were produced from the identical sheet of reconstituted tobacco according to reduce specification no. 3 are produced, a big fraction of the tobacco materials went to waste. These correspond to the shapes illustrated in Figures 9 and 10, respectively, for which the values of CCV listed within Filling cut tobacco the following Table 3 were measured. Tobacco minimize fillers according to the current invention could additionally be prepared by a way comprising offering a primary tobacco materials and cutting the first tobacco material in accordance with a first cut specification setting a minimum of predetermined first minimize width and first minimize length. Tobacco reduce filler in accordance with the present invention may be incorporated into a variety of smoking articles.
A tobacco reduce filler in accordance with claim 1 or 2, wherein the first tobacco material is a pre- processed tobacco material. In a third experiment, the cut specification no. 10 was slightly modified with a view to bettering the resistance of the particles to the stresses involved by the cigarette-making process. In specific, there was concern that in the course of the cigarette-making process the tobacco particle could be uncovered to high tensions and frictions which could cause particles prepared in accordance with the cut specification no. 10 to interrupt. This may have decreased the profit coming from the V-shape and proven by the CCV measurements described above. Figure thirteen depicts a schematic view of an apparatus for forming a tobacco reduce filler in accordance with the present invention. Figures depict several examples of significantly shapes into which tobacco materials for forming a cut filler in accordance with the present invention could also be reduce.
In most well-liked embodiments, the primary tobacco materials is shredded into strips from a sheet material having a thickness from about 0.05 mm to about 1 mm. Even extra ideally, the primary tobacco material is shredded into strips from a sheet material having a thickness from about zero.1 mm to about 0.three mm, most preferably from a sheet material having a thickness of about 0.2 mm. A tobacco reduce filler based on any certainly one of claims 1 to 9, wherein the primary Fashion tobacco pipe tobacco materials is shredded into strips each comprising at least a primary strip construction comprising a branching node from which an extra strip structure branches off, forming an angle with the first strip structure. Figures 10 and 12 show two examples of cut strips together with a number of V-shaped construction. Each V construction contains two substantially straight components forming an angle.
More preferably, the first tobacco materials is shredded into strips having a cut width of less than about 0.95 mm. Even extra ideally, the first tobacco material is shredded into strips having a minimize width of less than about 0.9 mm. In preferred embodiments, the first tobacco material is shredded into strips having a cut width from about zero.2 mm to about 1 mm. Preferably, the second tobacco materials is a natural tobacco leaf materials.
More ideally, the first tobacco material is shredded into strips having a cut width of no less than about zero.25 mm. Even more ideally, the first tobacco material is shredded into strips having a reduce width of at least about 0.3 mm. In addition, or as an alternative, the primary tobacco material is preferably shredded into strips having a minimize width of less than about 1 mm.
