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 material is ideally shredded into strips having a cut length of less than about 60 mm. More ideally, the first tobacco materials is shredded into strips having a minimize length of less than about 50 mm. Even extra ideally, the first tobacco pipe tobacco material is shredded into strips having a cut length of lower than about forty mm. In most well-liked embodiments, the first tobacco material is shredded into strips having a minimize size from about 5 mm to about 60 mm. The term “sectional minimize width” is used in the current specification to describe the side- to-side width of one such portion of a cut strip of tobacco material.
Should one such particle break at a location within the central V-shaped portion, the two resulting elements of the particles would nonetheless be effectively V-shaped. The highest CCV values were obtained for minimize specification no. three, 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 in accordance with reduce specification no. 3 are produced, a big fraction of the tobacco material went to waste. These correspond to the shapes illustrated in Figures 9 and 10, respectively, for which the values of CCV listed in the following Table three had been measured. Tobacco cut fillers according to the present invention may be ready by a way comprising providing a primary tobacco materials and chopping the primary tobacco materials in accordance with a primary reduce specification setting no much less than predetermined first minimize width and first reduce length. Tobacco reduce filler in accordance with the current invention could additionally be integrated into a selection of smoking articles.
A tobacco minimize filler based on declare 1 or 2, wherein the primary tobacco materials is a pre- processed tobacco material. In a third experiment, the cut specification no. 10 was slightly modified with a view to improving the resistance of the particles to the stresses concerned by the cigarette-making process. In particular, there was concern that in the course of the cigarette-making process the tobacco particle could be exposed to high tensions and frictions which could cause particles prepared in accordance with the reduce specification no. 10 to break. This could have lowered the benefit coming from the V-shape and proven by the CCV measurements described above. Figure thirteen depicts a schematic view of an equipment for forming a tobacco cut filler in accordance with the current invention. Figures depict several examples of particularly shapes into which tobacco material for forming a cut filler in accordance with the current invention could also be minimize.
For example, a bimodal distribution might correspond successfully to 2 groups of cut strips having totally different average cut lengths , one group being larger than the other. Preferably, the primary tobacco materials is shredded into strips from a sheet materials having a thickness of a minimum of about 0.05 mm. More preferably, the first tobacco material is shredded into strips from a sheet material having a thickness of no less than about 0.1 mm.
A tobacco minimize filler in accordance with any one of the previous claims, wherein the primary tobacco materials is shredded into strips having a reduce size from about 5 mm to about 60 mm. A tobacco cut filler based on any considered one of claims 2 to four, wherein the second tobacco materials is a natural tobacco leaf material. An angle of ninety levels was thought-about to be undesirable, in that it would lead essentially to a form quite similar to the form of Figure 6, and so an angle of 60 degrees was chosen for the “V” parts. Further, the tactic ideally comprises the step of mixing the minimize first tobacco materials and the reduce second tobacco materials.
In most popular embodiments, the first tobacco materials is shredded into strips from a sheet materials having a thickness from about zero.05 mm to about 1 mm. Even extra ideally, the first tobacco material is shredded into strips from a sheet material having a thickness from about 0.1 mm to about 0.three mm, most ideally from a sheet materials having a thickness of about 0.2 mm. A tobacco minimize filler based on any one of claims 1 to 9, wherein the first tobacco material is shredded into strips every comprising a minimum of a primary strip structure comprising a branching node from which a further strip structure branches off, forming an angle with the first strip construction. Figures 10 and 12 present two examples of cut strips including one or more V-shaped construction. Each V structure contains two considerably straight components forming an angle.
More preferably, the primary tobacco material is shredded into strips having a minimize width of lower than about zero.ninety five mm. Even more preferably, the primary tobacco material is shredded into strips having a reduce width of less than about 0.9 mm. In most popular embodiments, the primary tobacco material is shredded into strips having a minimize width from about 0.2 mm to about 1 mm. Preferably, the second tobacco material is a pure tobacco leaf material.
Alternative strategies for the manufacture of reconstituted tobacco sheets are additionally recognized to the expert individual. Throughout this specification, the expression “reconstituted tobacco sheet” is used to refer to a web, preferably with substantially uniform thickness, which may be produced by the rolling or casting of an aqueous slurry or pulp shaped from tobacco particles by considered one of a number of methods recognized within the art. Suitable by-products embody tobacco stems, tobacco stalks, leaf scraps, and tobacco mud produced during the manufacturing course of.
The cut width of one such Y-shaped strip corresponds considerably to the distance between the ends of the second and third strip portions as measured alongside a course perpendicular to the course defined by an axis of the primary strip portion. Within the identical Y-shaped strip, the sectional minimize width of every strip portion might instead Fashion tobacco pipe be measured along a path substantially perpendicular to the axis of each strip portion. In some cases, such as the place the reduce strip of tobacco materials is substantially rectangular , the sectional cut width and the strip cut width are the identical.
