The term “cut specification” is used throughout the specification to refer to the various geometric parameters characterising the strips obtained by subjecting a tobacco material to a chopping operation. Thus, in accordance to a given “minimize specification”, a tobacco materials shall be cut or shredded into strips having a predetermined cut width, reduce size, minimize form and so forth. Further, it will be desirable to provide one such improved course of that permits for a greater control of the form, dimension and properties of the reconstituted tobacco matter forming part of the reduce filler. At the identical time, it will be desirable to supply one such course of that doesn’t require any main modification of the standard apparatus and facilities used in the primary therapy of tobacco.
In most popular embodiments, the first tobacco material is shredded into strips from a sheet material having a thickness from about 0.05 mm to about 1 mm. Even more preferably, the first tobacco materials is shredded into strips from a sheet material having a thickness from about zero.1 mm to about zero.3 mm, most preferably from a sheet material having a thickness of about zero.2 mm. A tobacco cut filler based on any considered one of claims 1 to 9, wherein the primary tobacco material is shredded into strips each comprising at least a first strip construction comprising a branching node from which an extra strip structure branches off, forming an angle with the first strip structure. Figures 10 and 12 present two examples of reduce strips together with a quantity of V-shaped structure. Each V construction comprises two substantially straight elements forming an angle.
More preferably, the primary tobacco materials is shredded into strips having a reduce width of less than about 0.95 mm. Even extra preferably, the primary tobacco material is shredded into strips having a minimize width of less Filling cut tobacco than about 0.9 mm. In preferred embodiments, the first tobacco material is shredded into strips having a minimize width from about 0.2 mm to about 1 mm. Preferably, the second tobacco materials is a natural tobacco leaf material.
The yield of flat rolled stem which can be used directly as filler is elevated, and the common stem length and thus the typical size of cut filler from stem is elevated. A tobacco minimize filler according to any one of the preceding claims having a filling energy of no much less than three.5 cubic centimetres per gram at a reference moisture value of 12.5 percent oven volatiles. Accordingly, tobacco particles had been ready from the same sheet of reconstituted tobacco based on the minimize specification illustrated in Figure 12, whereby the minimize width SCW1 is of zero.9 millimetres, the reduce length CL1 is of four.ninety four millimetres and the global width CW1 is of 12.50 millimetres.
Sensors 40 and mass flow controllers 42, 44, if present, are operatively linked with a management unit forty six configured to control 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 pace at which the web of reconstituted tobacco is fed to the shredding device 36, so as 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 materials is reduce or shredded, the options of the first Fashion tobacco pipe tobacco material can advantageously be higher preserved each time the primary tobacco material is mixed, within the shredded state, with some other tobacco materials. This is particularly advantageous when the primary tobacco material is a pre-processed tobacco material, corresponding to a reconstituted tobacco sheet material. The “thickness” of a minimize strip of tobacco material for incorporation in cut fillers based on the present invention refers again to the distance between an upper floor and a lower surface of the portion of material forming the cut strip.
