A tobacco reduce filler according to declare 1 or 2, whereby the primary tobacco material is a pre- processed tobacco material. In a third experiment, the cut specification no. 10 was barely modified with a view to bettering the resistance of the particles to the stresses concerned by the cigarette-making process. In specific, there was concern that in the course of the cigarette-making course of the tobacco particle would be exposed to high tensions and frictions which Fashion tobacco pipe could trigger particles prepared in accordance with the reduce specification no. 10 to interrupt. This could have decreased the profit 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 minimize filler in accordance with the present invention. Figures depict a number of examples of significantly shapes into which tobacco material for forming a cut filler in accordance with the current invention may be reduce.
In most popular embodiments, the primary tobacco material is shredded into strips from a sheet material having a thickness from about zero.05 mm to about 1 mm. Even more preferably, the first tobacco materials is shredded into strips from a sheet materials having a thickness from about zero.1 mm to about zero.three mm, most preferably from a sheet materials having a thickness of about 0.2 mm. A tobacco reduce filler based on any considered one of claims 1 to 9, whereby the primary tobacco pipe tobacco materials is shredded into strips each comprising a minimum of a first strip construction comprising a branching node from which an extra strip structure branches off, forming an angle with the primary strip construction. Figures 10 and 12 present two examples of cut strips together with one or more V-shaped construction. Each V construction includes two considerably straight components forming an angle.
The reduce 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 course perpendicular to the course outlined by an axis of the first strip portion. Within the identical Y-shaped strip, the sectional reduce width of every strip portion might as an alternative be measured alongside a course considerably perpendicular to the axis of every strip portion. In some instances, such as the place the reduce strip of tobacco materials is substantially rectangular , the sectional reduce width and the strip minimize width are the same.
The time period “minimize specification” is used all through the specification to check with the assorted geometric parameters characterising the strips obtained by subjecting a tobacco materials to a chopping operation. Thus, in accordance to a given “minimize specification”, a tobacco material shall be reduce or shredded into strips having a predetermined minimize width, cut length, minimize form and so forth. Further, it will be desirable to supply one such improved process that allows for a greater control of the form, dimension and properties of the reconstituted tobacco matter forming a half of the reduce filler. At the same time, it would be fascinating to supply one such course of that does not require any major modification of the conventional equipment and facilities used in the main therapy of tobacco.
Sensors forty and mass move controllers 42, forty four, if present, are operatively related with a control unit forty six configured to control the operation of the equipment. In explicit, the management unit 46 adjusts the speed to the conveyor belt 38 in view of variations in the pace at which the online 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 shape of the strips into which the primary tobacco materials is cut or shredded, the options of the primary tobacco material can advantageously be better preserved whenever the primary tobacco materials is mixed, within the shredded state, with some other tobacco materials. This is particularly advantageous when the first tobacco material is a pre-processed tobacco material, such as a reconstituted tobacco sheet materials. The “thickness” of a reduce strip of tobacco materials for incorporation in reduce fillers based on the current invention refers again to the distance between an upper floor and a decrease surface of the portion of material forming the cut strip.
Should one such particle break at a location in the central V-shaped portion, the two ensuing components of the particles would still be successfully V-shaped. The highest CCV values had been obtained for reduce 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 according to reduce specification no. 3 are produced, a significant 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 3 were measured. Tobacco cut fillers according to the present invention may be ready by a way comprising providing a primary tobacco material and chopping the first tobacco materials in accordance with a first minimize specification setting no less than predetermined first reduce width and first minimize size. Tobacco cut filler in accordance with the present invention could also be integrated into a selection of smoking articles.
