The yield of flat rolled stem which can be used directly as filler is increased, and the average stem length and thus the typical length of minimize filler from stem is elevated. A tobacco cut filler based on any one of many previous claims having a filling energy of a minimum of 3.5 cubic centimetres per gram at a reference moisture value of 12.5 percent oven volatiles. Accordingly, tobacco particles were ready from the same sheet of reconstituted tobacco according to the minimize specification illustrated in Figure 12, wherein the minimize width SCW1 is of zero.9 millimetres, the reduce size CL1 is of 4.94 millimetres and the worldwide width CW1 is of 12.50 millimetres.
Even more ideally, first tobacco material is shredded into strips having a reduce length of at least about 15 mm. In addition, or in its place, the first tobacco materials is ideally shredded into strips having a cut size of lower than about 60 mm. More preferably, the primary tobacco materials is shredded into strips having a reduce length of lower than about 50 mm. Even more preferably, the first tobacco materials is shredded into strips having a minimize length of less than about 40 mm. In most popular embodiments, the first tobacco material is shredded into strips having a cut length from about 5 mm to about 60 mm. The time period “sectional minimize width” is used in the current specification to describe the side- to-side width of 1 such portion of a minimize strip of tobacco material.
Preferably, the primary tobacco material is shredded into strips whereby the cut size is greater than the reduce width. Further, when reconstituted tobacco undergoes the identical therapies as tobacco lamina, a major quantity of tobacco mud is fashioned. Besides, within the interest of process financial system, it is fascinating that the tobacco mud be reprocessed in some form or other to extend the overall efficiency.
Should one such particle break at a location in the central V-shaped portion, the 2 ensuing parts of the particles would still be successfully V-shaped. The highest CCV values have been obtained for reduce specification no. 3, which considerably corresponds to particles having a Y-shape. However, it was found that when particles have been produced from the same sheet of reconstituted tobacco in accordance with 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 in the following Table three were measured. Tobacco cut fillers according to the current invention may be ready by a way comprising offering a primary tobacco material and cutting the primary tobacco material in accordance with a first reduce specification setting a minimal of predetermined first minimize width and first reduce size. Tobacco cut filler in accordance with the current invention may be included into a selection of smoking articles.
According to a side of the current invention, there’s supplied a tobacco reduce filler comprising a primary tobacco material cut in accordance with a primary cut specification, wherein the primary minimize specification units a minimum of predetermined first minimize width and first minimize size. U.S. Patent 6,568,104 assigned to Philip Morris Inc., New York, New York, USA. A process for preparing tobacco stem to be used as filler for a smoking article contains classifying the green tobacco stem by diameter to provide a plurality of stem grades and rolling each grade individually. Each grade is rolled underneath rolling circumstances optimized for that grade including rolling the grade through the nip between rollers with the nip size being adjusted for each grade so as to realize a uniform rolled stem thickness and the oven volatiles content material of the stem being adjusted before the rolling.
Conventionally, reduce filler tobacco merchandise for smoking articles are fashioned predominantly from the lamina portion of the tobacco leaf, which is separated from the stem portion of the leaf during a threshing course of. Much of the stem portion that is still after the lamina has been eliminated and separated just isn’t used. However, it is not unusual to add some tobacco stems back into the cut filler along with the lamina.
In addition, the formation of tobacco mud is decreased compared with conventional manufacturing methods. Accordingly, the need to gather and re-process tobacco mud is significantly lowered and the overall efficiency of the manufacturing process is thus advantageously increased. A tobacco minimize filler according to any one of the previous claims, wherein the first tobacco materials is shredded into strips having a sinusoidal shape , whereby a wave length of the sinusoidal form is from about 1 mm to about 15 mm. A tobacco cut filler according to any one of many previous claims, whereby the primary tobacco material is shredded into strips from a sheet materials having a thickness from about zero.05 mm to about 1 mm. Table 2 under lists the values of CCV measured at a reference moisture worth of 12.5 percent oven volatiles for every pattern.
More preferably, the first tobacco materials is shredded into strips having a minimize width of lower than about 0.95 mm. Even more ideally, the primary tobacco material is shredded into strips having a cut width of less Fashion tobacco pipe than about zero.9 mm. In most popular embodiments, the first tobacco materials is shredded into strips having a reduce width from about 0.2 mm to about 1 mm. Preferably, the second tobacco materials is a pure tobacco leaf materials.
Even extra preferably, the first tobacco materials is shredded into strips from a sheet materials having a thickness of at least about zero.2 mm. In addition, or in its place, the primary tobacco materials is ideally shredded into strips from a sheet materials having a thickness of lower than about 1 mm. More ideally, the first tobacco material is shredded into strips from a sheet material having a thickness of lower than about zero.ninety five mm. Even more ideally, the first tobacco material is shredded into strips from a sheet materials having a thickness of lower than about 0.85 mm.
The cut width of 1 such Y-shaped strip corresponds substantially to the gap between the ends of the second and third strip parts as measured alongside a path perpendicular to the course defined by an axis of the first strip portion. Within the same Y-shaped strip, the sectional reduce width of each strip portion could as an alternative be measured alongside a direction substantially perpendicular to the axis of each strip portion. In some instances, similar to where the reduce strip of tobacco material is substantially rectangular , the sectional reduce width and the strip minimize width are the same.
