In practice, one such minimize strip could also be described as approximately wave-shaped or zigzag-shaped. Accordingly, geometric parameters corresponding to the height amplitude, peak-to-peak amplitude, interval of a sine wave may be used to explain the shape of 1 such minimize strips. A tobacco cut filler includes a primary tobacco materials reduce in accordance with a primary reduce specification, whereby the first cut specification units at least predetermined first cut width and first cut length. A tobacco minimize filler based on any one of many previous claims, wherein the primary tobacco materials is shredded into strips having a cut width from about 0.2 mm to about 1 mm.
Should one such particle break at a location within the central V-shaped portion, the 2 ensuing components of the particles would still be successfully V-shaped. The highest CCV values have been obtained for minimize specification no. 3, which considerably corresponds to particles having a Y-shape. However, it was discovered that when particles had been produced from the identical sheet of reconstituted tobacco based on minimize 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 the following Table three were measured. Tobacco cut fillers in accordance with the present invention may be ready by a technique comprising providing a primary tobacco material and cutting the first tobacco materials in accordance with a primary reduce specification setting no much less than predetermined first cut width and first minimize size. Tobacco minimize filler in accordance with the present invention may be included into a variety of smoking articles.
In the embodiment of Figure 10, the two straight elements are substantially perpendicular. The cut strip of Figure 12 may be regarded as comprising three V-shaped constructions of the kind illustrated in Figure 1 , whereby adjoining V-shaped constructions are related by the ends of respective straight components. In the embodiments of both Figures 10 and 12 the sectional reduce width within all of the structures forming the cut strips is substantially fixed. A tobacco minimize filler according to any one of the previous claims, wherein the reduce size distribution among the reduce strips of the primary tobacco materials is preferably unimodal. By means of example, the cut strip of Figure 9 comprises a first Y-shaped structure together with a primary branching node from which a second Y-shaped construction branches off.
According to a side of the current invention, there may be supplied a tobacco minimize filler comprising a primary tobacco material minimize in accordance with a primary minimize specification, whereby the primary minimize specification sets no much less than predetermined first cut width and first reduce size. U.S. Patent 6,568,104 assigned to Philip Morris Inc., New York, New York, USA. A course of 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 every grade separately. Each grade is rolled under 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 attain a uniform rolled stem thickness and the oven volatiles content material of the stem being adjusted earlier than the rolling.
The shredding gadget is configured to chop the reconstituted tobacco in accordance to a first cut specification, whereby both minimize width and minimize length are predetermined. The reduce strips are dropped onto a conveyor belt 38 arranged beneath the shredding gadget 36 and defining a collection surface upon which the minimize strips fall out of the shredding system. Additional means T could also be offered for tensioning the online of reconstituted tobacco as it is unwound off the bobbin. Further, the equipment 30 might comprise sensors forty for detecting the moisture content material of the online of reconstituted tobacco upstream of the shredding gadget 36. In addition, the apparatus 30 could comprise mass move controllers forty two, 44 tailored to regulate the speed at which the net of reconstituted tobacco is fed to the shredding gadget 36 and the speed of the conveyor belt 38.
For example, a bimodal distribution may correspond successfully to two teams of cut strips having completely different common cut lengths , one group being bigger than the opposite. Preferably, the first tobacco material is shredded into strips from a sheet materials Filling cut tobacco having a thickness of no much less than about zero.05 mm. More ideally, the first tobacco material is shredded into strips from a sheet materials having a thickness of at least about 0.1 mm.
Conventionally, minimize filler tobacco products for smoking articles are formed predominantly from the lamina portion of the tobacco leaf, which is separated from the stem portion of the leaf during a threshing process. Much of the stem portion that continues Fashion tobacco pipe to be 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 minimize filler along with the lamina.
