Further, the second Y-shaped construction contains a second branching node from which an oblong structure branches off. In the embodiment of Figure 1 1 , the reduce strip comprises a first Y-shaped structure together tobacco pipe with a first branching node from which a second Y-shaped construction branches off. Further, the second Y-shaped construction contains a second branching node from which a 3rd Y-shaped construction branches off.
The yield of flat rolled stem which can be used directly as filler is increased, and the average stem length and thus the common length of reduce filler from stem is elevated. A tobacco reduce filler according to any one of the preceding claims having a filling power of a minimum of 3.5 cubic centimetres per gram at a reference moisture worth of 12.5 % oven volatiles. Accordingly, tobacco particles have been ready from the identical sheet of reconstituted tobacco according to the cut specification illustrated in Figure 12, whereby the reduce width SCW1 is of zero.9 millimetres, the reduce size CL1 is of 4.ninety four millimetres and the worldwide width CW1 is of 12.50 millimetres.
Even more ideally, the primary tobacco materials is shredded into strips from a sheet material having a thickness of at least about 0.2 mm. In addition, or in its place, the first tobacco materials is ideally shredded into strips from a sheet materials having a thickness of less than about 1 mm. More ideally, the primary tobacco material is shredded into strips from a sheet materials having a thickness of lower than about 0.ninety five mm. Even extra preferably, the first tobacco material is shredded into strips from a sheet materials having a thickness of lower than about 0.eighty five mm.
A tobacco reduce filler according to declare 1 or 2, whereby the first tobacco material is a pre- processed tobacco materials. In a 3rd experiment, the minimize specification no. 10 was barely modified with a view to enhancing the resistance of the particles to the stresses concerned by the cigarette-making process. In explicit, there was concern that in the course of the cigarette-making process the tobacco particle could be exposed to high tensions and frictions which might trigger particles ready in accordance with the minimize specification no. 10 to break. 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 apparatus for forming a tobacco minimize filler in accordance with the present invention. Figures depict a quantity of examples of significantly shapes into which tobacco material for forming a reduce filler in accordance with the current invention may be reduce.
More ideally, the primary tobacco material is shredded into strips having a minimize width of lower than about 0.95 mm. Even extra ideally, the first tobacco material is shredded into strips having a minimize width of lower than about zero.9 mm. In most popular embodiments, the primary tobacco material is shredded into strips having a cut width from about 0.2 mm to about 1 mm. Preferably, the second tobacco material is a pure tobacco leaf material.
Without wishing to be certain to theory, it will be appreciated that during any slicing, rolling or extruding operation, the tobacco fibres generally align in a given path, which can thus be recognized because the longitudinal course of the tobacco material. The “minimize length” of a cut strip of tobacco material for incorporation in minimize fillers in accordance with the present invention could due to this fact be measured along the main path of fibre alignment, which generally corresponds to the longitudinal direction. Thus, the minimize length of a person minimize strip can be precisely measured utilizing a standard measuring gadget underneath a microscope. In a standard process, reconstituted tobacco or tobacco stem materials or each are usually blended with threshed tobacco lamina to bear a series of therapies, such as conditioning and drying. To this function, a reconstituted tobacco sheet is typically ripped into randomly shaped sheet-like pieces having a non-uniform measurement, usually of several sq. centimetres.
Suitable pure tobacco leaf materials embody tobacco lamina, tobacco stem material and tobacco stalk material. The natural tobacco leaf material used because the second tobacco materials might embody any type of tobacco leaf, together with for example Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a combination thereof. A tobacco reduce filler in accordance with the present invention comprises a primary tobacco material cut in accordance with a first Fashion tobacco pipe cut specification, wherein the first minimize specification units at least predetermined first cut width and first cut length. The time period “filling energy” is used to explain the amount of space taken up by a given weight or mass of a tobacco material. The higher the filling energy of a tobacco materials, the lower the load of the material required to fill a tobacco rod of normal dimensions.
Sensors forty and mass flow controllers 42, 44, if present, are operatively connected with a control unit forty six configured to manage the operation of the equipment. In specific, the control unit 46 adjusts the velocity to the conveyor belt 38 in view of variations in the speed at which the web of reconstituted tobacco is fed to the shredding device 36, in order to prevent any undesirable accumulation of minimize strips on the conveyor belt. By finely controlling the dimensions and form of the strips into which the first tobacco material is cut or shredded, the features of the primary tobacco materials can advantageously be better preserved each time the primary tobacco materials is mixed, within the shredded state, with another tobacco material. This is especially advantageous when the primary tobacco materials is a pre-processed tobacco material, such as a reconstituted tobacco sheet materials. The “thickness” of a minimize strip of tobacco materials for incorporation in minimize fillers in accordance with the present invention refers to the distance between an upper surface and a decrease surface of the portion of fabric forming the cut strip.
Even more ideally, first tobacco material is shredded into strips having a cut size of at least about 15 mm. In addition, or as an alternative, the first tobacco material is ideally shredded into strips having a reduce length of lower than about 60 mm. More ideally, the primary tobacco materials is shredded into strips having a reduce length of less than about 50 mm. Even more preferably, the primary tobacco material is shredded into strips having a cut length of lower than about 40 mm. In preferred embodiments, the first tobacco materials is shredded into strips having a reduce size from about 5 mm to about 60 mm. The time period “sectional minimize width” is used within the present specification to describe the side- to-side width of one such portion of a minimize strip of tobacco material.
A tobacco reduce filler according to any one of many previous claims, whereby the first tobacco materials is a reconstituted tobacco sheet. Preferably, the minimize filler has a filling power of no less than about three.5 cubic centimetres per gram at a reference moisture worth of 12.5 percent oven volatiles. More ideally, the reduce Filling cut tobacco filler has a filling power of no much less than about four cubic centimetres per gram at a reference moisture value of 12.5 % oven volatiles. In addition, or in its place, the cut filler preferably has a filling energy of less than about 8 cubic centimetres per gram at a reference moisture value of 12.5 p.c oven volatiles.
