Sensors 40 and mass circulate controllers forty two, 44, if current, are operatively related with a control unit 46 configured to regulate the operation of the equipment. In specific, the control unit 46 adjusts the speed to the conveyor belt 38 in view of variations in the velocity at which the web of reconstituted tobacco is fed to the shredding gadget 36, in order to stop any undesirable accumulation of minimize strips on the conveyor belt. By finely controlling the size and form of the strips into which the primary tobacco materials is cut or shredded, the options of the primary tobacco materials can advantageously be better preserved every time the primary tobacco materials is mixed, in the shredded state, with some other tobacco material. This is particularly advantageous when the primary tobacco materials is a pre-processed tobacco materials, similar to a reconstituted tobacco sheet materials. The “thickness” of a reduce strip of tobacco materials for incorporation in minimize fillers in accordance with the current invention refers again to the distance between an higher surface and a lower floor of the portion of fabric forming the cut strip.
Without wishing to be sure to principle, it is going to be appreciated that in any slicing, rolling or extruding operation, the tobacco fibres usually align in a given direction, which may thus be recognized because the longitudinal course of the tobacco materials. The “cut size” of a minimize strip of tobacco material for incorporation in cut fillers based on the current invention may subsequently be measured alongside the principle path of fibre alignment, which typically corresponds to the longitudinal path. Thus, the cut size of a person minimize strip can be accurately measured utilizing a conventional measuring system under a microscope. In a standard course of, reconstituted tobacco or tobacco stem material or each are usually blended with threshed tobacco lamina to undergo a sequence of treatments, similar to conditioning and drying. To this function, a reconstituted tobacco sheet is often ripped into randomly formed sheet-like pieces having a non-uniform measurement, generally of several sq. centimetres.
A tobacco cut filler according to declare 1 or 2, wherein the primary tobacco material is a pre- processed tobacco materials. In a 3rd experiment, the cut specification no. 10 was slightly modified with a view to improving the resistance of the particles to the stresses involved by the cigarette-making process. In particular, there was concern that during the cigarette-making course of the tobacco particle can be uncovered to excessive tensions and frictions which could cause particles prepared in accordance with the reduce specification no. 10 to interrupt. This may have reduced the profit coming from the V-shape and proven by the CCV measurements described above. Figure 13 depicts a schematic view of an equipment for forming a tobacco cut filler in accordance with the present invention. Figures depict several examples of significantly shapes into which tobacco material for forming a minimize filler in accordance with the present invention may be cut.
More ideally, the primary tobacco materials is shredded into strips having a reduce width of lower than about zero.ninety five mm. Even more ideally, the first tobacco materials is shredded into strips having a reduce width of lower tobacco pipe than about 0.9 mm. In preferred embodiments, the first tobacco material is shredded into strips having a minimize width from about 0.2 mm to about 1 mm. Preferably, the second tobacco materials is a natural tobacco leaf material.
Suitable pure tobacco leaf materials embody tobacco lamina, tobacco stem material and tobacco stalk material. The pure tobacco leaf materials used as the second tobacco material might embody any kind of tobacco leaf, together with for example Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a mixture thereof. A tobacco cut filler in accordance with the current invention includes a first tobacco materials reduce in accordance with a primary Filling cut tobacco minimize specification, wherein the primary reduce specification sets no much less than predetermined first cut width and first reduce size. The time period “filling energy” is used to explain the amount of space taken up by a given weight or mass of a tobacco materials. The greater the filling energy of a tobacco materials, the decrease the weight of the material required to fill a tobacco rod of ordinary dimensions.
In most well-liked embodiments, the first tobacco materials is a pre-processed tobacco material. By “pre-processed tobacco material” reference is made throughout the specification to a tobacco materials produced by man from pure tobacco versus occurring naturally as such. It would due to this fact be fascinating to offer another tobacco minimize filler having improved filling power. At the identical time, it might be fascinating to offer a novel course of for manufacturing tobacco cut filler, whereby the filling power of the tobacco cut filler is improved and the production of tobacco dust is reduced. The current invention relates to the production of tobacco reduce filler comprising reconstituted tobacco and to a smoking article shaped from a tobacco rod comprising the minimize filler based on the invention.
Figures 1 to 12 shows minimize strips of a first tobacco material for incorporation in a minimize filler based on the present invention. The strips have been cut from a sheet of reconstituted tobacco having a thickness from about zero.05 mm to about 1 mm in accordance with a first cut specification, whereby the primary cut specification sets a predetermined first minimize width CW1 and a predetermined first reduce size CL1 . In addition, the primary reduce specification could additional set a predetermined first sectional cut width SCW1.
By means of instance, tobacco stems could additionally be ground to a fantastic powder after which mixed with tobacco mud, guar gum, and water to kind an aqueous slurry. This aqueous slurry may be forged and dried to kind a reconstituted tobacco sheet. As an alternative, suitable tobacco materials may be mixed in an agitated tank with water to obtain a pulp. This internet is fed onwards to a press, where the excess water is squeezed out of the net. Figure 13 illustrates an apparatus 30 for the manufacture of a tobacco cut filler in accordance with the present invention. A web 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding device 36.
Should one such particle break at a location within the central V-shaped portion, the 2 ensuing components of the particles would nonetheless be effectively V-shaped. The highest CCV values have been obtained for cut specification no. 3, which substantially corresponds to particles having a Y-shape. However, it was discovered that when particles were produced from the identical sheet of reconstituted tobacco based on reduce specification no. 3 are produced, a significant 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 were measured. Tobacco cut fillers according to the present invention may be ready by a method comprising providing a primary tobacco materials and cutting the primary tobacco materials in accordance with a primary minimize specification setting a minimum of predetermined first cut width and first minimize length. Tobacco reduce filler in accordance with the current invention may be included into a variety of smoking articles.
The reduce width of 1 such Y-shaped strip corresponds considerably to the space between the ends of the second and third strip portions as measured along a direction perpendicular to the path outlined by an axis of the first strip portion. Within the same Y-shaped strip, the sectional minimize width of each strip portion could as a substitute be measured along a direction substantially perpendicular to the axis of each strip portion. In some cases, similar to where the cut strip of tobacco materials is substantially rectangular , the sectional minimize width and the strip reduce width are the same.
