The minimize 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 course perpendicular to the direction defined by an axis of the first strip portion. Within the identical Y-shaped strip, the sectional cut width of every strip portion may as a substitute be measured along a course substantially perpendicular to the axis of every strip portion. In some circumstances, such as where the cut strip of tobacco material is substantially rectangular , the sectional reduce width and the strip minimize width are the same.
More ideally, the primary tobacco material is shredded into strips having a cut width of less than about 0.95 mm. Even extra ideally, the first tobacco materials 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 minimize width from about zero.2 mm to about 1 mm. Preferably, the second tobacco materials is a natural tobacco leaf material.
Sensors forty and mass circulate controllers 42, forty four, if present, are operatively linked with a management unit forty six configured to manage the operation of the equipment. In explicit, the management unit forty six adjusts the speed to the conveyor belt 38 in view of variations in the speed at which the online of reconstituted tobacco is fed to the shredding device 36, in order to stop any undesirable accumulation of cut strips on the conveyor belt. By finely controlling the dimensions and shape of the strips into which the first tobacco material is cut or shredded, the features of the first tobacco materials can advantageously be better preserved every time the primary tobacco material is blended, in the shredded state, with another tobacco materials. This is especially advantageous when the first tobacco material is a pre-processed tobacco material, corresponding to a reconstituted tobacco sheet material. The “thickness” of a cut strip of tobacco materials for incorporation in reduce fillers in accordance with the current invention refers back to the distance between an upper surface and a lower surface of the portion of material forming the cut strip.
In most well-liked embodiments, the primary tobacco materials is shredded into strips from a sheet material having a thickness from about zero.05 mm to about 1 mm. Even more ideally, the first tobacco material is shredded into strips from a sheet material having a thickness from about zero.1 mm to about 0.three mm, most preferably from a sheet material having a thickness of about zero.2 mm. A tobacco minimize filler according to any considered one of claims 1 to 9, wherein the first Fashion tobacco pipe tobacco materials is shredded into strips every comprising a minimal of a first strip structure comprising a branching node from which an additional strip structure branches off, forming an angle with the primary strip structure. Figures 10 and 12 show two examples of reduce strips including one or more V-shaped construction. Each V structure contains two considerably straight elements forming an angle.
Figures 1 to 12 reveals cut strips of a primary tobacco materials for incorporation in a reduce filler according to the present 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 primary cut specification, whereby the primary minimize specification units a predetermined first cut width CW1 and a predetermined first reduce size CL1 . In addition, the first minimize specification may additional set a predetermined first sectional reduce width SCW1.
Without wishing to be bound to principle, will probably be appreciated that during any cutting, rolling or extruding operation, the tobacco fibres usually align in a given path, which may thus be identified because the longitudinal direction of the tobacco material. The “cut size” of a minimize strip of tobacco material for incorporation in minimize fillers in accordance with the current invention might subsequently be measured alongside the main course of fibre alignment, which typically corresponds to the longitudinal direction. Thus, the reduce length of a person reduce strip could be accurately measured using a traditional measuring device underneath a microscope. In a traditional process, reconstituted tobacco or tobacco stem material or both are sometimes blended with threshed tobacco lamina to undergo a series of remedies, corresponding to conditioning and drying. To this function, a reconstituted tobacco sheet is usually ripped into randomly shaped sheet-like pieces having a non-uniform dimension, generally of a number of sq. centimetres.
Further, the second Y-shaped structure includes a second branching node from which a rectangular construction branches off. In the embodiment of Figure 1 1 , the reduce strip includes a first Y-shaped construction including Filling cut tobacco a first branching node from which a second Y-shaped structure branches off. Further, the second Y-shaped structure contains a second branching node from which a third Y-shaped structure branches off.
In addition, a second couple of blends was used, that contained 70 % by weight of pure tobacco particles and 30 percent by weight of reconstituted tobacco particles minimize in accordance with the specifications of Figures 1 1 and 12, respectively. Thus, the cut width of a person reduce strip is taken at the level along the length of the strip that yields the biggest cross-sectional area. Further, the filling energy of the shredded first tobacco materials can be maximised by selecting an acceptable first cut specification. This results in an improved filling energy of the reduce filler as a complete, significantly when the primary tobacco material is blended with at least one other tobacco materials.
A tobacco reduce filler according to any one of the previous claims, whereby the primary tobacco materials is a reconstituted tobacco sheet. Preferably, the cut filler has a filling power of no much less than about three.5 cubic centimetres per gram at a reference moisture worth of 12.5 percent oven volatiles. More ideally, the cut filler has a filling energy of at least about 4 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 power of less than about 8 cubic centimetres per gram at a reference moisture value of 12.5 p.c oven volatiles.
