Should one such particle break at a location in the central V-shaped portion, the 2 resulting parts of the particles would nonetheless 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 according to cut specification no. three are produced, a major 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 Fashion tobacco pipe the following Table 3 were measured. Tobacco cut fillers based on the current invention could additionally be ready by a way comprising providing a primary tobacco material and slicing the first tobacco materials in accordance with a first minimize specification setting no much less than predetermined first reduce width and first minimize size. Tobacco minimize filler in accordance with the present invention could also be incorporated into a variety of smoking articles.
Further, the second Y-shaped structure includes a second branching node from which an oblong structure branches off. In the embodiment of Figure 1 1 , the cut strip contains a first Y-shaped structure together with a first branching node from which a second Y-shaped structure branches off. Further, the second Y-shaped construction comprises a second branching node from which a third Y-shaped construction branches off.
Figures 1 to 12 shows reduce strips of a primary tobacco material for incorporation in a minimize filler based on the current invention. The strips have been minimize from a sheet of reconstituted tobacco having a thickness from about 0.05 mm to about 1 mm in accordance with a first cut specification, whereby the first reduce specification sets a predetermined first minimize width CW1 and a predetermined first cut length CL1 . In addition, the primary reduce specification could further set a predetermined first sectional reduce width SCW1.
Without wishing to be bound to theory, it will be appreciated that during any cutting, rolling or extruding operation, the tobacco fibres typically align in a given course, which can thus be identified because the longitudinal course of the tobacco materials. The “reduce length” of a minimize strip of tobacco materials for incorporation in reduce fillers based on the current invention may therefore be measured along the main course of fibre alignment, which usually corresponds to the longitudinal path. Thus, the reduce size of an individual reduce strip could be precisely measured utilizing a standard measuring device under a microscope. In a standard process, reconstituted tobacco or tobacco stem materials or each are typically blended with threshed tobacco lamina to bear a series of remedies, similar to conditioning and drying. To this objective, a reconstituted tobacco sheet is usually ripped into randomly formed sheet-like pieces having a non-uniform dimension, generally of several sq. centimetres.
The reduce width of 1 such Y-shaped strip corresponds considerably to the distance between the ends of the second and third strip portions as measured alongside a path perpendicular to the path defined by an axis of the primary strip portion. Within the same Y-shaped strip, the sectional minimize width of each strip portion may as an alternative Filling cut tobacco be measured alongside a path considerably perpendicular to the axis of each strip portion. In some instances, such as the place the cut strip of tobacco materials is substantially rectangular , the sectional minimize width and the strip cut width are the identical.
More ideally, the first tobacco material is shredded into strips having a cut width of a minimum of about 0.25 mm. Even more ideally, the primary tobacco materials is shredded into strips having a cut width of a minimum of about 0.3 mm. In addition, or as an alternative, the primary tobacco material is preferably shredded into strips having a reduce width of less than about 1 mm.
By method of example, tobacco stems could also be floor to a fine powder and then mixed with tobacco dust, guar gum, and water to type an aqueous slurry. This aqueous slurry may be cast and dried to form a reconstituted tobacco sheet. As another, appropriate tobacco supplies may be combined in an agitated tank with water to obtain a pulp. This web is fed onwards to a press, where the excess water is squeezed out of the net. Figure 13 illustrates an equipment 30 for the manufacture of a tobacco minimize 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.
Sensors 40 and mass flow controllers 42, forty four, if present, are operatively related with a management unit forty six configured to control the operation of the apparatus. In specific, the control unit 46 adjusts the velocity 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 shape of the strips into which the primary tobacco material is cut or shredded, the options of the first tobacco material can advantageously be better preserved each time the primary tobacco material is mixed, within the shredded state, with some other tobacco materials. This is particularly advantageous when the first tobacco materials is a pre-processed tobacco materials, such as a reconstituted tobacco sheet materials. The “thickness” of a minimize strip of tobacco materials for incorporation in minimize fillers based on the present invention refers to the distance between an higher floor and a lower surface of the portion of fabric forming the reduce strip.
