A device of processing a low ignition propensity cigarette paper and a device of manufacturing a low ignition propensity cigarette paper including the same are provided.
BACKGROUND ARTIn 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.
When the coated low ignition propensity cigarette paper is dried or cooled, the coated cigarette paper may be curled by contraction of a coating layer, so that imbalance may be generated in drying or cooling and poor moving of the cigarette paper may be generated.
The above information disclosed in this Background section is only for enhancement of understanding of the background of the invention and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.
DISCLOSURE OF INVENTION Technical ProblemAn embodiment may reduce imbalance in drying or cooling of a low ignition propensity cigarette paper.
An embodiment may reduce poor moving of a low ignition propensity cigarette paper.
The present invention may be used to achieve other objects that are not stated in detail, other than the objects described above.
Solution to ProblemAn exemplary embodiment provides a device of processing a low ignition propensity cigarette paper, which includes a concave or convex surface portion facing a surface of a low ignition propensity cigarette paper having a coating portion, and a body portion supplied with energy from a heat source or a cooling source, and dries or cools the low ignition propensity cigarette paper.
A cross-sectional shape of the surface portion may correspond to a cross-sectional shape of the low ignition propensity cigarette paper.
A radius R may be about 100 mm to 200 mm in a degree of curving of the surface portion.
An exemplary embodiment provides a device of manufacturing a low ignition propensity cigarette paper, which includes a coating unit that discharges a low ignition propensity cigarette paper having a coated portion by coating a cigarette paper with a coating composition, and a processing unit that dries or cools the low ignition propensity cigarette paper, by using a concave or convex surface portion facing a surface of the low ignition propensity cigarette paper.
The processing unit may further have a body portion that is supplied with energy from a heat source or a cooling source.
ADVANTAGEOUS EFFECTS OF INVENTIONAn exemplary embodiment may reduce imbalance in drying or cooling of a low ignition propensity cigarette paper and may decrease poor moving of the low ignition propensity cigarette paper.
The present invention will be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the accompanying drawings, portions unrelated to the description will be omitted in order to obviously describe the present invention, and like reference numerals will be used to describe like components throughout the present specification. Further, detailed descriptions of well-known technologies are not provided.
Hereinafter, a device of processing a low ignition propensity cigarette paper and a device of manufacturing a low ignition propensity cigarette paper according to an exemplary embodiment will be described in detail with reference to
Referring to
The low ignition propensity cigarette paper 19 coated with the coating composition 17 through the coating unit 100 passes through processing units 210 and 220 that dry or cool coating portions 18. 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
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
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.
