Problems solved by technology

[0019]However, the pressure (flow rate) of the pressurized air introduced into the air nozzle 10b has been set to be higher than before due to the high speed of filter element manufacturing in recent years. high demand, and consequently, it becomes more and more difficult to smoothly carry out the transfer of the tow T from the tow supply roller 9 to the tongue 12

Embodiment 1

[0093] Using a filter element winding machine, KDF-2 / AF-2 (Germany, "HAUNI" manufactured by Hauni Co., Ltd.), the acetate fiber tow T with a single fiber fineness of 3.3 (dtex) and a total fineness of 38885 (dtex) is wound at a winding speed The manufacture of the filter element was carried out at 400 m / min, so that the circumference was 24.3 (mm), the length was 120 (mm), and the filling amount of acetate tow T was 0.66 (g / rod) and 0.76 (g / rod).

[0094] In this embodiment 1, in the filter core winding machine, as figure 1 and figure 2 As shown, two air nozzles, namely, a first air nozzle 10 a on the tow supply roller side and a second air nozzle 10 b on the tongue side, are disposed between the tow supply roller 9 and the tongue 12 . The said 1st air nozzle 10a is arrange|positioned so that the front-end|tip part of the tow exit part may be located in the position 45 mm from the pressurized air discharge port 19a of the 2nd air nozzle 10b by the tongue side. The inner di...

Embodiment 2

[0101] The downstream side of the second air nozzle 10b on the tongue side is provided with a funnel-shaped guide portion 11, and the funnel-shaped guide portion 11 is provided with a plurality of small holes on the circumferential surface. Next, implement the manufacture of the filter element.

[0102] At this time, 300 manufactured filter elements were taken out as samples at intervals, and Table 2 shows the weight of the filter elements and the evaluation results of air permeability resistance.

Embodiment 3

[0113] Using filter winding machine, KDF-2 / AF-2 (Germany, "HAUNI" manufactured by Hauni Company), the acetate fiber tow with a single fiber fineness of 3.3 (dtex) and a total fineness of 38885 (dtex) is wound at a winding speed of 400m / min to carry out the manufacture of the filter element so that the circumference is 24.3 (mm), the length is 120 (mm), and the filling amount of acetate fiber tow is 0.76 (g / rod).

[0114] At this time, if Figure 4 and Figure 5 As shown, between the tow supply roller 9 and the tongue 12, the front end of the tow outlet portion of the first air nozzle 10a on the supply roller side is connected to the pressurized air outlet 19a of the second air nozzle 10b on the tongue side. The distance between them was set to 45 mm, and the inner diameter of the front end portion of the above-mentioned tow exit portion was set to 15 mm. Moreover, the downstream side of the 2nd air nozzle 10b is provided with the funnel-shaped guide part 11, and the said fun...

Abstract

A manufacturing apparatus for a plug of a cigarette filter capable of providing particularly a high quality cigarette filter with uniform air permeation resistance used as the index of the filtration performance of the filter by reducing a variation in the filling amount of tow in the plug, and made economically advantageous by a reduced capital investment to an existing plug hoist in manufacturing the plug filled with a large amount of tow and a manufacturing method for the filter. First and second air jets (10a, 10b) are installed between a tongue (12) and tow supply rolls (9), a distance between the outlet tip of the first air jet (10a) on the tow supply roll side and the pressurized air jetting port (19a) of the second air jet (10b) on the tongue side is set to 25 to 110 mm, and the tip inner diameter of the tow outlet part of the first air jet is set to 12 to 15 mm.

Description

technical field [0001] The present invention relates to a device for manufacturing a cigarette filter element and a method for manufacturing a cigarette filter, and more particularly to a device for manufacturing a filter element for a high-quality cigarette filter whose air resistance is uniform as an index of the filtering performance of the filter, and the filter element for the filter. Manufacturing method. Background technique [0002] There are proposals to use crimped tows such as acetate fibers or polyolefins, or the products obtained by making paper and pulp into sheets to form cigarette filters, which have been put into practical use, and are generally cigarettes composed of acetate tows Filters are favored because of their superior taste in cigarettes, and are used in most cigarette products. [0003] In the manufacture of cigarette filters using acetate tow, generally such as Figure 4 Filter Winder shown. [0004] In addition, acetate tow is generally supplied...
