By contrast, in a multimodal distribution, the likelihood mass perform has multiple maxima, which signifies that among the reduce strips of the primary tobacco material there are multiple values of reduce length that occur most often. In the context of the current specification, a distribution having multiple native maxima is considered multimodal. It will be appreciated that the different modes in a multimodal distribution may have different frequencies, such that, among the reduce strips of the primary tobacco material, one modal value of reduce length will occur more incessantly than another modal worth.
A tobacco reduce filler in accordance with any one of many preceding claims, wherein the first tobacco materials is shredded into strips having a cut length from about 5 mm to about 60 mm. A tobacco cut filler according to any one of claims 2 to 4, wherein the second tobacco material is a pure tobacco leaf material. An angle of 90 degrees was considered to be undesirable, in that it might lead essentially to a shape fairly similar to the form of Figure 6, and so an angle of 60 levels was chosen for the “V” elements. Further, the method preferably comprises the step of mixing the cut first tobacco material and the reduce second tobacco material.
In some embodiments, tobacco reduce filler according to the invention could additionally be used in the tobacco rod of a flamable smoking article, such as a filter cigarette, cigarillo or cigar. Alternatively, the reduce filler may be used to supply Fashion tobacco pipe the tobacco aerosol generating substrate in a distillation primarily based smoking article, or an electrically heated smoking system. Alternatively, the minimize filler may be used as a roll-your-own or make-your-own product, or free tobacco product to be used in a pipe.
A tobacco cut filler based on any one of many previous claims, wherein the primary tobacco material is a reconstituted tobacco sheet. Preferably, the minimize filler has a filling power of a minimum of about three.5 cubic centimetres per gram at a reference moisture worth of 12.5 % oven volatiles. More ideally, the reduce filler has a filling power of a minimal of about four cubic centimetres per gram at a reference moisture value of 12.5 % oven volatiles. In addition, or instead, the minimize filler ideally has a filling energy of lower than about 8 cubic centimetres per gram at a reference moisture worth of 12.5 p.c oven volatiles.
Without wishing to be bound to concept, it goes to be appreciated that in any chopping, rolling or extruding operation, the tobacco fibres generally align in a given course, which may thus be identified as the longitudinal path of the tobacco material. The “cut length” of a minimize strip of tobacco material for incorporation in cut fillers based on the current invention may subsequently be measured along the principle course of fibre alignment, which generally corresponds to the longitudinal course. Thus, the minimize length of an individual cut strip could be precisely measured using a conventional measuring gadget 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 treatments, similar to conditioning and drying. To this objective, a reconstituted tobacco sheet is typically ripped into randomly shaped sheet-like pieces having a non-uniform measurement, usually of a quantity of square centimetres.
