According to an embodiment, the base paper 401 may be inserted into a gap between the first roller 411 and the second roller 412, and at this time, the base paper 401 may be transported by various transport means. According to an embodiment, the transport means for the base paper 401 may be composed of rollers, a conveyor belt, or both. Depending on the number and / or arrangement of the rollers and / or conveyor belts, various transport paths for the base paper 401 may be set.

[0087] According to an embodiment, the transport path of the raw paper 401 may be set in various ways, and according to one example, it may be set to a straight path, a curved path, or a U-shaped path. However, the transport path of the raw paper 401 may be determined by various factors such as the arrangement of the processing device, and is not limited to the above-mentioned types of paths.

[0088] According to one embodiment, the first roller 411 and the second roller 412 may compress and crumple the base paper 401 to perform crimping. According to one embodiment, the first roller 411 and the second roller 412 may rotate in opposite directions to each other to transport the base paper 401 that has undergone the crimping process to the next processing device. The base paper 401 may be subjected to the crimping process to generate crimped paper 402, and sufficient tensile force may be applied to the crimped paper 402. According to one embodiment, the crimped paper 402 may pass through the moisturizer injection device 420 while suspended in the air.

[0089] According to an embodiment, the first roller 411 and the second roller 412 may each include projections and recesses in order to effectively compress and crumple the base paper 401. According to an embodiment, the crimping process may be smoothly performed by the rotational force of the first roller 411 and the second roller 412, and the base paper 401 may be appropriately compressed and crumpled to be suitable for application of a moisturizing agent, thereby producing the crimped paper 402.

[0090] According to one embodiment, the paper 402 that has been crimped by applying a moisturizer 320 can be coated with a moisturizer through a plurality of nozzles to produce moisturizer-containing paper 403. According to one embodiment, the step 320 of applying a moisturizer can be performed through a moisturizer applicator 420.

[0091] According to one embodiment, the step 320 of applying the moisturizer may be performed by spraying 0.5 mg / mm to 5 mg / mm of moisturizer based on the longitudinal direction of the crimped paper 403. According to one embodiment, the amount of moisturizer applied may be 4 mg / mm or less, 3 mg / mm or less, 2 mg / mm or less, or 1 mg / mm or less, and preferably 0.5 mg / mm to 4 mg / mm, 0.5 mg / mm to 3 mg / mm, or 0.5 mg / mm to 2 mg / mm.

[0092] FIG. 5 is a conceptual diagram showing a method for applying a moisturizer in a moisturizer application device according to one embodiment of the present invention.

[0093] 5(a), the moisturizer application device 420 may include a plurality of nozzles 501. According to one embodiment, the crimped paper 402 may be transported at a certain distance from the nozzles 501, and the moisturizer sprayed from the nozzles 501 may be applied to the surface of the crimped paper 402. According to one embodiment, in the step 330 of producing paper containing moisturizer, the moisturizer may be sprayed from the nozzles 501 positioned at a distance from the crimped paper 402.

According to one embodiment, the number of nozzles 501 is preferably two or three.

[0096] According to one embodiment, the plurality of nozzles 501 each spray humectant in a certain direction, so that the humectant is sprayed on the crimped paper 402 to form a plurality of parallel marks 504. The humectant can be sprayed at the same time by the number of nozzles 501, so that the humectant content of the crimped paper 402 can be improved. According to one embodiment, the humectant content of the crimped paper 402 can be improved, so that the conditioning period can be shortened and it can be easy to achieve a desired suction resistance.

[0097] Here, the conditioning period may refer to the period during which the humectant is absorbed and spread evenly on the paper filter of the cigarette filter. In order to shorten the conditioning period, it may be necessary to apply the humectant as evenly as possible to the paper in the step 320 of applying the humectant so that the humectant spreads quickly throughout the paper.

[0106] According to one embodiment, the tobacco extract may contain at least one of nicotine salt, nicotine, nicotine base, free nicotine, and nicotine derivatives. For example, nicotine salt is a substance naturally formed in tobacco leaves, and may be produced by reacting nicotine with an acid substance. The acid substance may include lactic acid or pyruvic acid, and it will be readily understood by those of ordinary skill in the art that it may further include organic acids that may react with nicotine to form nicotine salts.

[0107] According to one embodiment, the moisturizing agent-containing paper 403 produced in the moisturizing agent application step 320 can be used to produce the paper 404 with granules attached thereto in the granule addition step 330. According to one embodiment, the granule addition step 330 is performed by randomly adding granules onto the moisturizing agent-containing paper 403 in a granule addition device 430, specifically, the granules are attached onto the moisturizing agent.

[0108] According to one embodiment, the paper 404 on which the granules are placed, which is produced in the step 330 of feeding the granules, may be wrapped in filter paper in the step 340. According to one embodiment, the paper 404 on which the granules are placed may be transported and collected in one place through the discharge port 440.

[0127] The present invention will now be described in more detail with reference to examples and comparative examples.

[0128] However, the following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0129] [Experimental Example 1] In order to confirm the granule adhesion depending on the type and physical properties of the base paper, cigarette filters were manufactured using various base papers. The cigarette filters were manufactured by the steps of crimping the base paper to produce crimped paper, applying a humectant to the crimped paper through multiple nozzles, pouring granules onto the paper containing the humectant, and wrapping the paper with the granules attached with a filter wrapper. As shown in Table 1 below, various types of base papers were used, glycerin was applied as a humectant at 1 mg / mm, and shellac-coated activated carbon was added as granules at 5 mg / mm. The granule adhesion of cigarette filters according to various embodiments using different types of base paper according to Experimental Example 1 is shown in Table 1 below.

[0130] [Table 1]

[0131] Referring to Table 1 above, the more non-porous the base paper is, the better the granule adhesion is. 2 ~30g / m 2 It can be confirmed that the stability of the granules is good when the product of the width and basis weight of the base paper is 5.2 g / m to 5.6 g / m.

[0132] [Experimental Example 2] In order to evaluate the tobacco taste depending on the amount of granules added to a cigarette filter, cigarette filters were manufactured with various amounts of granules added. The cigarette filters were manufactured by the steps of crimping a base paper to produce crimped paper, applying a humectant to the crimped paper through a number of nozzles, adding granules onto the paper containing the humectant, and wrapping the paper with the granules attached in a filter wrapper. As shown in Table 2 below, evaluations were carried out with different amounts of granules added, and the base paper had a basis weight of 24 g / m. 2The non-porous paper was used, glycerin was applied as a moisturizing agent at 1 mg / mm, and shellac-coated activated carbon was used as granules. The shellac-coated activated carbon had an average diameter of 0.45 mm to 0.60 mm, and the total sugar content was 0.35%. The results of the evaluation of the taste of cigarette filters and cigarettes containing the same with different granule loading amounts in Experimental Example 2 are shown in Table 2 below.

[0133] [Table 2]

[0134] Referring to Table 2 above, it can be seen that when the amount of granules added is 3 mg / mm to 5 mg / mm, the amount of nicotine and moisture transfer is good, and cigarettes using such cigarette filters have a good smoking taste.

[0135] [Experimental Example 3] In order to evaluate the granule adhesion of different humectants in cigarette filters, cigarette filters were manufactured using various humectants. The cigarette filters were manufactured by the steps of crimping a base paper to produce crimped paper, applying a humectant to the crimped paper through multiple nozzles, injecting granules onto the humectant-containing paper, and wrapping the paper with the granules attached in a filter wrapper. As shown in Table 3 below, evaluations were carried out for different humectants, and the base paper was 24 g / m2 in basis weight. 2 The non-porous paper was used, and the moisturizer was applied at 1 mg / mm, and shellac-coated activated carbon was used as the granules. The granule adhesion according to the different types of moisturizers in Experimental Example 3 is shown in Table 3 below.

[0136] [Table 3]

[0137] Referring to Table 3 above, it can be seen that all of the moisturizing agents, EVA, guar gum, glycerin, and methylcellulose, can be used to improve the stability of the granules, and only slight differences can be seen in terms of the generation of unpleasant odors.
