In general, various kinds of leaf tobaccos are mixed and processed to obtain desired smell and taste in order to manufacture cigarettes. Next, cut tobacco leaves or shredded tobaccos are produced by cutting the processed leaf tobaccos and a cigarette without a filter is produced by wrapping the cut tobacco leaves with a cigarette paper. Next, a filter may be attached to the non-filter cigarette. A cigarette filter may contain active carbon and a flavor material. A cigarette filter may be formed in a mono-filter or a multi-filter and is wrapped with a cigarette filter-wrapping paper. The cut tobacco leaves and the tobacco filter are connected by a tipping paper and the tipping paper may have fine holes. The cigarette paper may be manufactured not only to achieve target tar and target nicotine in smoking by appropriate porosity and combustibility, but to be provided with the peculiar smoke flavor of the cigarette. The cigarette paper may be made of flax or wood pulp. A low ignition propensity cigarette paper is coated with a substance such as starch in a band shape and the porosity of the coating portion is low, so that when the combustion of the tobacco reaches the band portion, the amount of oxygen flowing into the cut tobacco leaves reduces and the cigarette may be put out.

For example, the processing units 210 and 220 that dry the cigarette paper 19 may be supplied with heat energy into bodies of the processing units 210 and 220 from a heat source and the processing units 210 and 220 cooling the cigarette paper 19 may be supplied with cooling energy into bodies of the processing units 210 and 220.
Since the low ignition propensity cigarette paper 19 coated with the coating composition 17 has a property that the coating composition 17 retracts when the coating portion 18 is dried or cooled, the low ignition propensity cigarette paper 19 may have a concave or convex shape. The surface of the processing unit 210 may have a concave or convex shape, corresponding to the concave or convex shape of the low ignition propensity cigarette paper 19. Accordingly, the degree of drying or cooling of the surface of the cigarette paper may be balanced, and poor moving of the low ignition propensity cigarette paper due to insufficient drying or cooling may be reduced. For example, in the degree of curving of the concave or convex shape, the radius R may be about 100 mm to about 200 mm.
On the contrary, in a processing device having a flat surface, the degree of drying or cooling of a cigarette paper may be unbalanced when a low ignition propensity cigarette paper is dried or cooled, so that poor moving of the cigarette paper may be generated.
Moisture contents of a cigarette paper were measured at several portions by a processing device having a concave or convex shape and a processing device having a flat surface, as shown in FIG. 6, are shown in Table 1. In the degree of curving of the processing device having a concave surface, the radius R is about 150 mm.
Table 1
Moisture content at each portion of cigarette paper (%)
Surface of processing device A B C
Concave surface 5.6 5.7 5.7
Flat surface 7.3 5.5 7.6
As shown in Table 1, it may be seen that the moisture contents of the cigarette paper 19 measured by the processing device having a concave surface is uniform regardless of the portions.
One or more of the processing units 210 and 220 may be disposed over the cigarette paper 19 and one or more of the processing units 210 and 220 may be disposed under the cigarette paper 19.
The low ignition propensity cigarette paper 19 before or after passing the processing units 210 and 220 may be moved by a moving unit.
The low ignition propensity cigarette paper 19 may be supplied to a device of manufacturing a cigarette which includes a low ignition propensity cigarette paper through the moving unit.
A device of manufacturing a low ignition propensity cigarette paper may be implemented in an on-line type by being mounted in a device of producing a cigarette or may be implemented in an off-line type by being mounted outside a device of producing a cigarette. Referring to FIGS. 7 and 8, a cigarette 1 has a cigarette column portion 10 that is burned and a cigarette filter portion 20 that filters tobacco smoke. The cigarette column portion 10 may be wrapped with the cigarette paper 19 and the cigarette filter portion 20 may be wrapped with a cigarette filter wrapping paper 28. The cigarette column portion 10 and the cigarette filter portion 20 may be connected by the tipping paper 29. The circumference of a cigarette may be about 5mm to 30mm. The cigarette filter portion 20 may be omitted. The cigarette column portion 10 includes cut tobacco leaves 11 cut from a leaf tobacco processed by various methods. The cigarette filter portion 20 may has a first filter portion 21. The first filter portion 21 may be made of acetate tow or paper. The cigarette filter portion 20 may be a multi-filter including two or more filter members. For example, referring to FIG. 9, the cigarette filter portion 20 may include a first filter portion 20, a second filter portion 22, and a third filter portion 23. Further, the cigarette filter portion 20 may include three filter members or four filter members. The cigarette filter portion 20 may contain an absorbent and a flavor material. For example, the absorbent may be active carbon and the flavor material may be an herb-smelled material. One or more filter members in a multi-filter may contain at least one of an absorbent or a flavor material. For example, referring to FIG. 9, at least one of the second filter portion 22 and the third filter portion 23 may contain at least one of an absorbent or a flavor material. The low ignition propensity cigarette paper 19 has one or more coating portions 18. For example, the coating portion 18 may have a band shape, but may have other various shapes. The number, thickness, and shape of the coating portion 18 may be changed in various ways and the gaps between the coating portions 18 may be changed in various ways. The coating portion 18 may reduce porosity of the cigarette paper 19, and accordingly, when combustion of the cigarette reaches the coating portion 18, the amount of oxygen flowing into the cigarette column portion 10 decreases and the cigarette 1 may be put out. The cigarette paper 19 having the coating portions 18 is also called a low ignition propensity cigarette paper. A coating composition is coat at the coating portion 18. For example, the porosity of the cigarette paper 19 may be about 85 cu or less and the porosity of the coating portion 18 may be about 5 cu to about 20 cu. The thickness of the base paper of the cigarette paper may be about 30 μm to about 60 μm and the basis weight of the base paper may be about 15 g/m2 to about 40 g/m2. The thickness of the coating portion 18 may be about 5 μm or less and the basis weight of the coating portion 18 may be about 15 g/m2 or less. The ratio of the weight of the coating composition to the total weight of the cigarette paper 19 and the coating composition may be about 35 wt% or less. When the coating portion 18 has a band shape, the weight of the coating composition per band may be 2.5 mg or less. The cigarette paper 19 may include filler, and accordingly, opacity of a cigarette paper may increases and porosity may be provided to a cigarette paper, and flatness and ash integrity of a cigarette paper may be improved and whiteness of a cigarette paper may increase. For example, the filler may be calcium carbonate, titanium dioxide, or magnesium oxide. The filler may be used by about 20 wt% to about 40wt% to the entire weight of the cigarette paper.
While this invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
