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 primary tobacco material 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 material having a thickness of about zero.2 mm. A tobacco reduce filler according to any considered one of claims 1 to 9, whereby the primary tobacco material is shredded into strips each comprising at least a first strip structure comprising a branching node from which an extra strip construction branches off, forming an angle with the primary strip construction. Figures 10 and 12 show two examples of cut strips together with a quantity of V-shaped construction. Each V structure includes two considerably straight components forming an angle.
Preferably, the first tobacco materials is shredded into strips whereby the minimize length is larger than the reduce width. Further, when reconstituted tobacco undergoes the identical treatments as tobacco lamina, a major quantity of tobacco dust Filling cut tobacco is fashioned. Besides, within the interest of course of financial system, it’s fascinating that the tobacco mud be reprocessed in some kind or other to increase the general effectivity.
The shredding device is configured to chop the reconstituted tobacco in accordance to a first minimize specification, whereby each reduce width and reduce size are predetermined. The cut strips are dropped onto a conveyor belt 38 organized beneath the shredding gadget 36 and defining a collection floor upon which the reduce strips fall out of the shredding gadget. Additional means T could also be supplied for tensioning the online of reconstituted tobacco as it is unwound off the bobbin. Further, the apparatus 30 may comprise sensors forty for detecting the moisture content material of the web of reconstituted tobacco upstream of the shredding system 36. In addition, the equipment 30 could comprise mass flow controllers 42, forty four adapted to regulate the velocity at which the web of reconstituted tobacco is fed to the shredding device 36 and the pace of the conveyor belt 38.
Within a minimize strip of tobacco materials, the sectional minimize width will be the considerably same for all of the strip portions. While this could be preferable, the sectional reduce width may differ from one strip portion to another. Typically, previous to being reduce, a tobacco materials might endure different mechanical operations, such as rolling or extrusion.
In some embodiments, tobacco cut filler based on the invention could additionally be used within the tobacco rod of a combustible smoking article, such as a filter cigarette, cigarillo or cigar. Alternatively, the cut filler could also be used to provide the tobacco aerosol generating substrate in a distillation based smoking article, or an electrically heated smoking system. Alternatively, the cut filler could also be used as a roll-your-own or make-your-own product, or unfastened tobacco product to be used in a pipe.
Even extra preferably, first tobacco materials is shredded into strips having a reduce size of no much less than about 15 mm. In addition, or in its place, the primary tobacco materials is ideally shredded into strips having a minimize length of less than about 60 mm. More ideally, the primary tobacco material is shredded into strips having a cut size of lower than about 50 mm. Even extra preferably, the first tobacco material is shredded into strips having a reduce length of less than about forty mm. In most well-liked embodiments, the first tobacco materials is shredded into strips having a cut size from about 5 mm to about 60 mm. The term “sectional cut width” is used in the current specification to describe the side- to-side width of one such portion of a cut strip of tobacco material.
More ideally, the primary tobacco materials is shredded into strips having a cut width of at least about zero.25 mm. Even more preferably, the first tobacco material is shredded into strips having a cut Fashion tobacco pipe width of at least about zero.3 mm. In addition, or as an alternative, the primary tobacco materials is ideally shredded into strips having a cut width of less than about 1 mm.
The time period “minimize specification” is used all through the specification to refer to the various geometric parameters characterising the strips obtained by subjecting a tobacco materials to a slicing operation. Thus, in accordance to a given “reduce specification”, a tobacco material shall be cut or shredded into strips having a predetermined minimize width, reduce size, minimize form and so forth. Further, it will be desirable to provide one such improved course of that permits for a better control of the shape, measurement and properties of the reconstituted tobacco matter forming part of the cut filler. At the same time, it will be desirable to offer one such process that doesn’t require any major modification of the conventional apparatus and facilities used in the major remedy of tobacco.
For example, a bimodal distribution could correspond successfully to 2 groups of cut strips having different common cut lengths , one group being bigger than the other. Preferably, the first tobacco materials is shredded into strips from a sheet material having a thickness of no much less than about zero.05 mm. More preferably, the first tobacco material is shredded into strips from a sheet material having a thickness of a minimal of about 0.1 mm.
