Further, the second Y-shaped structure contains a second branching node from which an oblong structure branches off. In the embodiment of Figure 1 1 , the cut strip comprises a first Y-shaped structure together Filling cut tobacco with a primary branching node from which a second Y-shaped construction branches off. Further, the second Y-shaped construction includes a second branching node from which a third Y-shaped structure branches off.
Figures 1 to 12 exhibits cut strips of a primary tobacco materials for incorporation in a minimize filler based on the current invention. The strips have been reduce from a sheet of reconstituted tobacco having a thickness from about 0.05 mm to about 1 mm in accordance with a primary cut specification, wherein the first reduce specification units a predetermined first cut width CW1 and a predetermined first cut length CL1 . In addition, the primary cut specification might additional set a predetermined first sectional cut width SCW1.
The cut width of one such Y-shaped strip corresponds substantially to the space between the ends of the second and third strip portions as measured alongside a direction perpendicular to the course outlined by an axis of the first strip portion. Within the same Y-shaped strip, the sectional cut width of each strip portion could instead be measured alongside a course substantially perpendicular to the axis of every strip portion. In some circumstances, corresponding to where the minimize strip of tobacco materials is substantially rectangular , the sectional cut width and the strip cut width are the same.
More ideally, the primary tobacco material is shredded into strips having a cut width of less than about 0.ninety five mm. Even extra ideally, the primary tobacco materials is shredded into strips having a minimize width of lower than about 0.9 mm. In most popular embodiments, the first tobacco materials is shredded into strips having a reduce width from about 0.2 mm to about 1 mm. Preferably, the second tobacco materials is a pure tobacco leaf materials.
Sensors 40 and mass move controllers 42, 44, if present, are operatively linked with a control unit forty six configured to regulate the operation of the equipment. In particular, the control unit forty six adjusts the speed to the conveyor belt 38 in view of variations within the speed at which the online of reconstituted tobacco is fed to the shredding device 36, so as to stop any undesirable accumulation of minimize strips on the conveyor belt. By finely controlling the scale and shape of the strips into which the primary tobacco materials is cut or shredded, the features of the primary tobacco pipe tobacco material can advantageously be better preserved every time the first tobacco materials is mixed, in the shredded state, with some other tobacco material. This is especially advantageous when the first tobacco materials is a pre-processed tobacco materials, corresponding to a reconstituted tobacco sheet material. The “thickness” of a minimize strip of tobacco material for incorporation in reduce fillers according to the present invention refers to the distance between an higher floor and a lower surface of the portion of fabric forming the cut strip.
Without wishing to be sure to concept, it will be appreciated that in any slicing, rolling or extruding operation, the tobacco fibres generally align in a given path, which can thus be identified because the longitudinal course of the tobacco materials. The “reduce size” of a reduce strip of tobacco materials for incorporation in minimize fillers according to the present invention might therefore be measured alongside the primary course of fibre alignment, which generally corresponds to the longitudinal course. Thus, the reduce size of an individual minimize strip can be precisely measured using a traditional measuring device under a microscope. In a standard process, reconstituted tobacco or tobacco stem material or both are typically blended with threshed tobacco lamina to endure a sequence of treatments, corresponding to conditioning and drying. To this function, a reconstituted tobacco sheet is typically ripped into randomly shaped sheet-like items having a non-uniform measurement, usually of a number of sq. centimetres.
Even extra preferably, the primary tobacco material is shredded into strips from a sheet materials having a thickness of a minimal of about 0.2 mm. In addition, or instead, the first tobacco material is ideally shredded into strips from a sheet material having a thickness of lower than about 1 mm. More ideally, the first tobacco material is shredded into strips from a sheet material having a thickness of lower than about zero.ninety five mm. Even extra ideally, the first tobacco materials is shredded into strips from a sheet materials having a thickness of less than about zero.85 mm.
Reconstituted tobacco is shaped from tobacco materials such as tobacco stems, tobacco stalks, leaf scraps and tobacco mud, that are produced in the course of the manufacturing processes of tobacco merchandise. Such tobacco material may, for example, be ground to a fantastic powder after which combined with water and typically with a binder, similar to guar gum, to form a slurry. This slurry is then forged onto a supportive floor, similar to a belt conveyor, and dried to type a sheet (so referred to as ‘cast leaf) that could be faraway from the supportive floor and wound into bobbins.
Should one such particle break at a location in the central V-shaped portion, the 2 ensuing elements of the particles would still be effectively V-shaped. The highest CCV values have been obtained for minimize specification no. three, which substantially corresponds to particles having a Y-shape. However, it was discovered that when particles had been produced from the identical sheet of reconstituted tobacco in accordance with minimize specification no. three 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 within the following Table 3 had been measured. Tobacco cut fillers in accordance with the current invention may be ready by a technique comprising offering a first tobacco materials and slicing the first tobacco material in accordance with a first cut specification setting no less than predetermined first reduce width and first minimize length. Tobacco cut filler in accordance with the present invention may be included into quite a lot of smoking articles.
