Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to the manufacture of tobacco products, and more particularly to a method of manufacturing cigarettes, in which the type of manufacturing method involves wrapping a pre-prepared tobacco rod in a paper web. These steps consist of applying an adhesive along one of the edges of the web and gluing the seam to form a cigarette rod. The present invention further comprises
It relates to a cigarette manufactured by the method described above.

[0002]

BACKGROUND OF THE INVENTION In order to effectively manufacture cigarettes to meet market demands, the market must be constantly supplied with many types of similar but different products. Thus, starting from the storage of cut tobacco, in one or another stage of production, it becomes necessary to divide the stored tobacco into a plurality of unit treatment bodies, the unit treatment bodies or batches Each is directed towards work where the tobacco treatment process and final conditioning are different. To date, from the point of view of manufacturing various end products, tobacco production processing operations necessarily have already undergone different adjustment operations, dividing tobacco stock into different locations and temporary storage. In doing so, efforts have been made to organize the production in such a way that the storage time is as short as possible and the storage is as low as possible. In the various different adjustment methods that are actually performed, it must be taken into consideration that various additives are incorporated into the tobacco from the viewpoints described above, and the mixture of these additives plays a part in the best flavor of tobacco. And gives the tobacco its unique properties. Cigarette manufacturing methods have to be classified according to various products, which causes a problem of diversification of processing steps. For example, there are various kinds of flavoring agents even for the additives in question, and these are prepared in a solution form with water, alcohol, or other appropriate medium, and they are sprayed on stored products of cut tobacco. Then, the intended cigarette is manufactured.

At every stage of the production of consumer goods,
In order to reduce manufacturing costs, it is constantly sought to operate as efficiently as possible. It is now possible to appropriately simplify the tobacco treatment process for cigarette manufacture by introducing at least some of the so-called "head flavor" flavoring agents until the time when the cigarette rod is formed. I know that.

Among those proposed so far are, for example, US Pat. Nos. 4941486, No. 3625224 and No. 3041211.
, They propose to add certain additives into the seam adhesive during the manufacture of cigarettes. However, in each of these cases, the device is adapted for a particular purpose other than that of the invention. Therefore, US patent
According to No.4941486, the introduction of "flavor precursors" is designed to give tobacco smoke a specific flavor and no improvement in tobacco quality is specifically intended. U.S. Pat.Nos. 3625224 and 3041211 relate to improving tobacco quality, the method is to use additives, which are added by spraying, dipping or otherwise, but in these patents. The disclosed technique does not suggest increasing the efficiency of operation as provided by the present invention.

[0005]

OBJECTS OF THE INVENTION Accordingly, it is an object of the present invention to provide an improved method of making cigarettes which is not only simpler and more economical than conventional methods, but at the same time It improves the quality of tobacco.

To this end, in the process according to the invention, in a process of the type described at the outset, the additives which improve the quality of the tobacco are simply placed in the seam adhesive.

[0007] Generally, the additives are distributed to give the tobacco a preset flavor.

In the cigarettes produced by the method described above, the seam adhesive alone contains additives that improve tobacco quality.

[0009]

The preferred embodiments of the present invention are as follows:
A detailed description will now be given with reference to the accompanying drawings. FIG. 1 is a schematic front view, part of which shows a cross section, by means of which the method according to the invention is carried out.

The final operation in the manufacture of cigarettes is, as is well known, a series of cigarette rods consisting of tobacco rods which are the contents wrapped in a paper web and are cut into rods of a certain length. The edges are overlapped and glued to each other. The cigarette rod-shaped body is itself formed as follows. That is, the double-cut tobacco storage product that has undergone various adjustment work performed in advance does not need to be described in detail here, but is stored in a container in bulk, and is generally sucked out from the container. It is conveyed on a conveyor belt where it is formed into a continuous cylindrical rod. At this point, the paper web is continuously unwound from the paper wrapper to wrap the tobacco rod inside. An adhesive is applied to one of the two edges of the web, and the cigarette rod formed here is introduced into a forming tool, where the edges of the web are overlapped and glued to each other. A seam is formed by this gluing.

FIG. 1 attached herewith shows a tobacco rod-shaped body 1 as a content.
And a paper web 2 is shown in cross section, and a front view of the forming tool 3 can be seen behind the cross section.

Mounted between the tool 3 and the cross section is a device 5, which is arranged such that the edge 2a of the web 2 (seen on the left in the figure) passes just before the end of the nozzle 6. With a nozzle 6. The device 5 is provided with a fluid adhesive, such as polyvinyl acetate glue, by any suitable means not shown. A desired amount of liquid starch or gelatin adhesive is adhered by the action of pressure applied to the device 5 and capillaries into the edge of the edge 2a of the web 2. In an embodiment of the method described herein, the aromatic compounds of the finest flavoring agents, such as vanillin, maltol, furanelle, pyrazine, etc., have been previously dissolved in the adhesive so that aromas of this kind are obtained. If it is desired to change from the production of a type of tobacco with an aromatic compound to a type of tobacco with another type of aromatic compound,
Simply changing the adhesive applied by the device 5 is sufficient for the purpose. The above-mentioned operations for producing tobacco are all the same, and there is no longer a need for differential storage.

It has been found so far that, for various flavors, the total amount that must be placed in each cigarette is added to it without changing its gas properties to the adhesive. It means that you can get it. The amount of flavoring agent currently in use added to each solvent is
About 1.5% by weight of tobacco, the same amount of solvent-free flavor can be included in the mass of the adhesive used to glue the wrapping paper (web) I know so far. It has also been found that the adhesive acts as a fixative and that the amount of flavor needed to achieve that effect, as well as the effect previously described, can be reduced.

Introducing a flavoring agent into the adhesive has a number of other advantages over making the tobacco manufacturing process and storage more efficient. In particular, the ripening period required for flavored tobacco is shorter when the flavorant is fixed in the adhesive than when sprayed onto the tobacco. In addition, the flavor stability is even better if the flavor emission during smoking of cigarettes made in this way is more normal.

In contrast, in the embodiment described above, the "head flavor" is dissolved in the adhesive before it reaches the device 5 and this method may likewise be implemented in other ways. Occurs. Thus, in particular, the dispersing device
Dispersion of the flavoring agent placed in the downstream of the adhesive applicator 5 and added to the paper web sizing portion is performed before the webs are overlaid by the forming tool 3.

In the adhesive-based manner, it is possible to introduce the entire amount of flavor into the cigarette, thereby imparting to the cigarette the previously envisioned specificity. Not only one kind of flavoring agent but also a mixture of several flavoring agents in the amount of the flavoring agent in the solution melted in the adhesive or the amount of the flavoring agent dispersed in the web portion glued at the entrance of the molding tool. Can be included as well, and the amount of this mixture alone can likewise impart the desired unique properties to the cigarette. From the point of view of producing this cigarette, the introduction of a flavor with special characteristics can be completely eliminated from the tobacco treatment process. Tobacco prepared in this way could therefore also be used in the manufacture of one or more cigarettes with different final qualities.

It should be noted that the quality of the paper used does not pose a particular problem in carrying out the method described above. Commonly used papers are easy to accept the adhesive into which the flavoring agent dissolves. The examples are used to show the following data: The standard amount of adhesive used for producing cigarettes is 4.4 g per 3,500 cigarettes. This value is for polyvinyl acetate. So far we know: adhesives
65.6 g of a flavoring agent such as ethyl vanillin per 1,000 g is effective, based on conventional technology, per Kg of tobacco
An effect equal to that of 0.1 g of flavoring is produced. These discoveries were made by American Tobacco Blended Tobacco. They are also effective against many types of tobacco. All of the flavoring agents described to the left produce appreciable quality improvements when they alone are placed in the seam adhesive in the indicated proportions. The effect on the adhesive is imperceptible. An important conclusion of the described method is that the solvent previously used to dissolve the adhesive is unnecessary.

Finally, one thing to note is that
Using ethyl vanillin in the method described
On the one hand, it imparts an aromatic effect to the taste of smoked tobacco and, on the other hand, a secondary aroma effect.
