Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement of an endless tape used when feeding into a cigarette molding machine and manufacturing cigarettes into products.

[Prior Art] In general, a forming line in the tobacco production process (wrapping paper on an endless tape on which chopped tobacco leaves are placed is wound into a long cylindrical shape with a small diameter in a rounding machine and sent out, After that, a filter is attached to one end of the cigarette to make the cigarette into a product.In order to shape the cigarette, a narrow endless tape woven with weft and warp threads is used.

Conventionally, this type of endless tape has been proposed in which the weft threads are run along the warp threads, and the surface of the tape is coated with a thin film of synthetic resin. According to this prior art, although it is possible to give strength to the tape, the unevenness on the tape surface is filled in by the coating and the tape surface is formed flat, so the surface area of the heat dissipation surface is reduced. Heat-sealing (This is done when heat-sealing the edge of the cigarette wrapping paper after it has been rolled into a cylindrical shape in a rounding machine, and when attaching a filter to one end of the cigarette. Usually 150~
Endless Tape 1
There was a drawback that the yield rate of products that could be rolled up by a book deteriorated over time (it is preferable that the cross section of the manufactured cigarettes be a perfect circle and have a uniform diameter over the entire length, but products that are not in such a state (the probability of occurrence increases with time).

[Problems to be solved by the invention] Therefore, the purpose of the invention is to sufficiently dissipate the heat received when heat-sealing the edges of wrapping paper, and to prevent the tape from elongating and shrinking due to heat. To provide an endless tape for cigarette molding which is free from deformation and has excellent durability.

Another object of the present invention is to provide an endless tape for cigarette molding that causes less fatigue of the fabric and has a high yield of products (cigarettes) per tape.

Another object of the present invention is to provide an endless tape for cigarette molding that can prevent slips between the tape and the cigarette, as well as between the tape and the filter, and can maintain a uniform length and cross-sectional diameter of the product over a long period of time. It's about doing.

[Means for Solving the Problems] The endless tape for cigarette molding according to the present invention is an endless tape for cigarette molding formed by weaving weft threads running through the warp threads, and includes:
The surface of the tape is formed by weaving the warp and weft threads together to create fluff.

In a preferred embodiment, the warp yarn is formed of a core yarn and a winding yarn that covers the outer periphery of the core yarn, and the fluff is applied to the winding yarn, and the tape is formed using the warp yarn. .

[Example] Hereinafter, the endless tape according to the present invention will be explained along with a preferred example shown in the accompanying drawings.

1 to 4, the endless tape 1 according to the present invention has warp threads 3, 3... and weft threads 2, 2.
Run ... and densely weave it, width 18 to 22
It is formed into an endless fabric with a length of 2300 to 3500 mm and a thickness of 0.55 to 0.66 mm. Fuzzes 6 are raised over the entire surface of the uneven portion of the tape surface formed by weaving the warp threads 3 and the weft threads 2 together. In this case, as shown in FIGS. 3 and 5, among the undulations that occur in the arrangement direction of the warp threads 3, 3... of the endless tape 1 (X-X direction in FIGS. 2 and 3), The convex portion 4 has short bristles 6, and the concave portion 5 has slightly long bristles 6.
It's bristling. Thus, the height of this fluff 6 varies depending on the part, but it is 0.02 mm to 0.02 mm from the fabric surface.
It is brushed to a height of about 0.10mm. In this embodiment, the fluff 6 is applied to the warp yarns 3, 3, . . . , and the tape 1 is formed using these warp yarns. Furthermore, the warp threads 3, 3, . In this way, the fluff 6 is applied only to the winding yarn 12 by fluffing the covered winding yarn 12, without damaging the core yarn 11 itself. figure,
The tensile strength in the direction XX in FIG. 3 also does not decrease.

Thus, the wrapping paper 7 on the endless tape 1 fed into the entrance of the rounding machine 20 is placed on the tape 1 with the cigarette 8 on it (the seventh
At the exit of the rounding machine 20, the wrapping paper 7 for wrapping cigarettes is stably wrapped around the endless tape 1 (FIG. 8).

In the above examples, the fuzz was applied to the tape by using warp yarns that were previously provided with fuzz, but after the tape was formed by weaving using warp yarns without fuzz, the fuzz was applied to the surface. Of course, it is also possible to add fluff. Furthermore, in the embodiment, an example was shown in which the endless tape according to the present invention was used in a cigarette rounding machine, but the process of attaching the tobacco filter after passing through the cigarette rounding machine also used the method according to the present invention. It goes without saying that endless tape can be used.

[Effects of the invention] According to the invention, there is no slippage between the tape and the cigarette wrapping, or the tape and the filter during rounding, making it possible to form cigarettes in a stable state for a long period of time.

In addition, according to the present invention, since the bristles allow a large contact area with the air, it is possible to ensure the dissipation of heat during the heat sealing applied to the edge of the wrapping paper during commercialization. It is possible to obtain an endless tape for cigarette molding which has less fatigue caused by the heat of the tape itself and is excellent in durability, and also has the advantage of improving the yield of manufactured cigarettes.
