Description

  The present invention relates to a filter cigarette manufacturing machine having at least one perforated row in chip paper, a manufacturing method thereof, and a filter cigarette.

  If at least one perforation is formed in the chip paper of the filter cigarette, outside air is introduced into the filter of the filter cigarette through this perforation. The outside air thus introduced dilutes the mainstream smoke of the filter cigarette within the filter of the filter cigarette, thereby providing the user with a light smoking feeling. This kind of perforation is formed in advance in a paper web for forming chip paper. For example, laser light can be used for the formation of perforation (see paragraph 0047 of Patent Document 1 below).

Special Table 2005-535323 Publication (WO 2004/014161)

Since the above-mentioned perforation penetrates only the tip paper and is formed in advance in the paper web, the amount of outside air introduced through the perforation into the filter, that is, the so-called ventilation amount cannot be adjusted in the manufacturing process of the filter cigarette.
In this regard, if the perforations are formed in the filter cigarette manufacturing process, the perforations can extend through the chip paper and into the filter, and the size of the perforations can be changed. The adjustment becomes easier.

However, when perforations are formed in the manufacturing process of the filter cigarette, the following problems occur.
Since glue is applied to the entire back surface of the chip paper, this back surface is formed as an adhesive surface for both the cigarette and the filter. For this reason, if the perforation is formed in the filter by penetrating the chip paper by laser light irradiation, the laser light irradiation generates combustion products (ash) from the glue, chip paper and filter material, and such The combustion product is scattered as dust with adhesion.

  Such dust scattering causes dust to adhere to the outer surface of the manufactured filter cigarette, so that not only the appearance of the filter cigarette is impaired, but also the perforations are blocked by the dust, and the filter It becomes a big factor to deteriorate the quality of cigarette. Also, dust accumulates on various machine elements of the filter cigarette manufacturing machine, and adversely affects the operation of the manufacturing machine.

  The object of the present invention is to significantly reduce the scattering of dust having adhesiveness when forming perforations penetrating the tip paper in the manufacturing process of the filter cigarette, and thus the quality of the filter cigarette is deteriorated by the dust. An object of the present invention is to provide a filter cigarette manufacturing machine, a method for manufacturing the filter cigarette, and a filter cigarette.

  Since the paste layer forming apparatus of the present invention includes the above-described configuration, when the above-described perforations are formed in the filter through the chip paper by laser light in the manufacturing process of the filter cigarette, dust is scattered around. Even so, these dusts are not adhesive. Therefore, according to the manufacturing machine of the present invention, generation of dust having adhesiveness is greatly reduced in the formation process of the perforations.

It is the schematic which shows the measuring apparatus of distribution ratio Qe / Qa of mainstream smoke.

Referring to FIG. 1, the filter cigarette FC according to the first embodiment of the present invention has one cigarette 10. A filter 12 is disposed adjacent to one end of the cigarette 10, and the cigarette 10 and the filter 12 are connected to each other by winding a chip paper 14 coated with glue.
Such chip paper 14 covers the filter 12 and the cigarette 10 from the mouth end surface 12 e of the filter 12 to one end of the cigarette 10.

Further, the filter cigarette FC has at least one perforation in the tip paper 14. Specifically, the tip paper 14 has at least one perforation row 16. The perforation row 16 is formed by a large number of perforations 18, and the perforations 18 are distributed at intervals in the circumferential direction of the filter 12.
In the case of the first embodiment, the perforation row 16 is disposed in the vicinity of the mouth end 12e. The individual perforations 18 of such a perforation row 16 extend through the tip paper 14 to the interior of the filter 12 as is apparent from FIG. 2, while being inclined rather than perpendicular to the axis A of the filter cigarette FC. Yes. Therefore, the perforation 18 has an outer end that opens to the outer peripheral surface of the chip paper 14 in the vicinity of the mouth end surface 12e, and an inner end that is positioned closer to the cigarette 10 in the filter 12 than the outer end.

Note that the filter 12 of FIG. 2 is shown as a plane filter. This plain filter includes a bundle 12f of filter fibers and a winding paper 12w that wraps the bundle 12f in a cylindrical shape, and the above-described perforations 18 penetrate the chip paper 14 and the winding paper 12w and face the center (axis A) of the bundle 12f. It extends.
Furthermore, in the present embodiment, a non-adhesive zone Z is secured on the back surface of the chip paper 14. This non-adhesive zone Z is defined between two thin lines Lz added for convenience in FIG. 1 and forms an annular region over the entire circumference of the chip paper 14.

  Therefore, the chip paper 14 is bonded to the outer surface of the filter 12 in a region other than the non-bonded region Z. Further, since the non-adhesion zone Z does not have adhesiveness to the outer surface of the filter 12 (winding paper 12w), the non-adhesion zone Z of the lap seam formed by overlapping both ends of the chip paper 14 with each other The corresponding part is in a non-adhered state.

As is clear from FIG. 1, the outer ends of the perforations 18 forming the perforation row 16 are all arranged in the non-adhesive zone Z. Therefore, even if the perforation row 16 is formed in accordance with a manufacturing machine and a manufacturing method to be described later and the dust as described above is scattered around, the dust does not have adhesiveness. Therefore, even if the dust touches the outer surface of the filter cigarette FC, the dust does not adhere to the outer surface of the filter cigarette FC. As a result, the appearance of the filter cigarette FC is not damaged or the perforations 18 are not blocked due to the adhesion of dust to the outer surface of the filter cigarette FC, and the quality of the filter cigarette FC is stably maintained. The
Moreover, even if dust accumulates on each machine element of a manufacturing machine, removal of the accumulated dust is also easy.

When the above-described filter cigarette FC is smoked, the user holds the mouth end of the filter cigarette FC with the outer ends of the perforations 18 in the perforation row 16 positioned in the oral cavity. A one-dot chain line shown for convenience in FIG. 2 indicates a boundary between the inside of the oral cavity and the outside of the oral cavity.
In this state, if the user smokes the filter cigarette FC, most of the mainstream smoke generated from the cigarette 10 passes through the inside of the filter 12 and enters the user's mouth from the mouth end surface 12e to the axis A of the filter cigarette FC. (See arrow Cm in FIG. 2).

  On the other hand, a part of the mainstream smoke in the filter 12 is sent radially into the user's mouth through the perforations 18 (see arrow Cs in FIG. 2). The mainstream smoke indicated by the arrow Cs spreads more uniformly in the oral cavity than the mainstream smoke indicated by the arrow Cm. As a result, the user can feel the taste and flavor of the mainstream smoke more effectively.

Next, a manufacturing machine that performs the above-described method for manufacturing the filter cigarette FC will be described with reference to FIGS.
FIG. 3 schematically shows the entire manufacturing machine, which includes a filter mounting device 20. The filter mounting device 20 has a rod supply path 22 that connects between the cigarette rod making machine and the filter attachment section 24. The cigarette rod manufacturing machine sequentially manufactures double-length cigarettes WC, and the manufactured double-length cigarettes WC are supplied to the filter attachment section 24 via the rod supply path 22. Double-length cigarette WC has twice the length of cigarette 10 described above.

  The filter mounting device 20 has a filter supply path 26 that connects between the filter attachment section 24 and the hopper 28. A large number of double length filters WF are stored in the hopper 28. The filter supply path 26 takes out the double length filters WF one by one from the hopper 28, and sequentially supplies the taken double length filters WF to the filter attachment section 24. The double length filter WF has twice the length of the filter 12 described above.

  The manufacturing machine further includes a web supply device 30. The web supply device 30 has a web supply path 32 that connects between the filter attachment section 24 and the web roll WR. The web supply path 32 feeds the paper web PW for forming the above-described chip paper 14 from the web roll WR, and guides the sent paper web PW toward the filter attachment section 24.

Further, the manufacturing machine further includes a web cutting device 36 in addition to the glue applying device 34 as a glue layer forming device, and these glue applying device 34 and the web cutting device 36 are sequentially arranged in the web supply path 32 from the web roll WR side. Has been.
The glue applying device 34 applies glue to one side of the paper web PW to form an adhesive surface.
On the other hand, the web cutting device 36 cuts the paper web PW intermittently along the longitudinal direction thereof to sequentially form double-width paper WP (see FIG. 4). The double-width paper WP has a width twice that of the tip paper 14 described above.

  The double-width paper WP formed in this way is supplied to the filter attachment section 24 via the web supply path 32. Accordingly, the filter attachment section 24 is supplied with the double-length cigarette WC, the double-length filter WF, and the double-width paper WP, respectively. Form a cigarette WFC.

FIG. 4 shows a procedure for forming a double filter cigarette WFC, which will be described below.
First, the double-length cigarette WC is cut into two cigarettes 10 (FIG. 4 (a)). Thereafter, the two cigarettes 10 are separated from each other, and a predetermined space is secured between the cigarettes 10 (FIG. 4 ()). After this, the double length filter WF is placed in the space (FIG. 4 (c)), and the two cigarettes 10 are moved toward the double length filter WF and brought into close contact with the corresponding end face of the double length filter WF. Thereby, the intermediate product I of the double filter cigarette WFC is formed.

  Thereafter, the double-width paper WP is supplied to the intermediate product I (FIG. 4F), and the double-width paper WP is wound around the intermediate product I (FIG. 4E). Here, the double-width paper WP extends from the end of one cigarette 10 adjacent to one end of the double-length filter WF to the end of the other cigarette 10 adjacent to the other end of the double-length filter WF. As is clear from the above description, since the adhesive surface is formed on the back surface of the double-width paper WP, the double-width paper WP integrally connects the two cigarettes 10 and the double-length filter WF. A double filter cigarette WFC is formed (filter attachment process).

The double filter cigarette WFC formed in this way is sent from the filter attachment section 24 to the transfer path 38 of the manufacturing machine and transferred on the transfer path 38 (see FIG. 3).
In the transfer path 38, a laser drilling device 40, a cigarette cutting device 42, and an alignment device 44 are arranged, and these laser drilling device 40, cigarette cutting device 42, and alignment device 44 are sequentially arranged from the filter attachment section 24 side.

  As shown in FIG. 5, the laser drilling device 40 is disposed at a drilling position PP defined in the transfer path 38, and has a laser emitter 46 at the drilling position PP. The laser emitter 46 is positioned above the transfer path 38. When the double filter cigarette WFC reaches the punching position PP, the laser emitter 46 intermittently emits two laser beams Lb1 and Lb2 to the double sub paper WP of the double filter cigarette WFC.

The laser beams Lb1 and Lb2 are inclined at the same angle in opposite directions with respect to the double filter cigarette WFC, that is, the axis A of the filter cigarette FC.
Specifically, when the double-width paper WP is divided into left and right portions L and R at the center position CP in the axial direction of the double filter cigarette WFC, one laser beam Lb1 is irradiated to the right portion L as viewed in FIG. On the other hand, the left side portion R is irradiated with the other laser beam Lb2. Here, the distances between the irradiation positions of the laser beams Lb1 and Lb2 and the center position CP are the same, and the inclination angles of the laser beams Lb1 and Lb2 coincide with the inclination angles of the perforations 18 described above.

On the other hand, the double filter cigarette WFC is rotated once around its axis A as shown by an arrow CC in FIG. Here, the transfer speed V of the double filter cigarette WFC on the transfer path 38 and the reverse speed of the double filter cigarette WFC caused by the rotation of the double filter cigarette WFC coincide with each other, and the transfer of the double filter cigarette WFC is perforated. Temporarily stopped at position PP.
As a result, the laser beams Lb1 and Lb2 emitted intermittently form the two perforation rows 16 in the double filter cigarette WFC at the perforation position PP (laser perforation process). These perforation rows 16 are respectively positioned on both sides of the center position CP as shown in FIG. It goes without saying that each perforation 18 of the perforation row 16 extends through the double-width paper WP and into the double-length filter WF.

  Thereafter, the double filter cigarette WFC is transferred along the transfer path 38 from the piercing position PP. When the double filter cigarette WFC sequentially passes through the cigarette cutting device 42 and the aligning device 44, two filter cigarettes FC are formed from each double filter cigarette WFC, and thereafter, these filter cigarettes FC are aligned in the direction. Aligned.

FIG. 8 shows a procedure from formation to alignment of the filter cigarette FC, which will be described below.
First, the cigarette cutting device 42 cuts the double filter cigarette WFC at the center position CP (cigarette cutting step), and forms two filter cigarettes FC from the double filter cigarette WFC (FIG. 8A). Thereafter, the two filter cigarettes FC are separated from each other (FIG. 8B).

Of the two filter cigarettes FC, one filter cigarette FC is inverted and the direction thereof coincides with the direction of the other filter cigarette FC (FIG. 8 (c)). Thereafter, the two filter cigarettes FC are positioned forward and backward as viewed in the transfer direction of these filter cigarettes FC (FIG. 8 (c)-(d)), forming one filter cigarette FC row (FIG. 8 (d)). )-(e)).
Thereafter, the filter cigarette FC is supplied to the packaging machine, which forms a cigarette package.

The above-described glue application device 34 includes a configuration (procedure) for providing at least two non-adhesive zones Z on the double-width paper WP of the double filter cigarette WFC, and each non-adhesive zone Z is obtained from the double filter cigarette WFC. Assigned to each filter cigarette FC.
Specifically, as shown in FIG. 9, the glue application device 34 includes a glue transfer roller 48 and a pinch roller 50. When the paper web PW traveling on the web supply path 32 passes between the glue transfer roller 48 and the pinch roller 50, the glue transfer roller 48 applies glue on the back surface of the paper web PW. A glue layer, that is, an adhesive surface is formed except for (a glue application step).

  Here, in the case of the present embodiment, the target area includes the two side areas R1, R2 corresponding to the two non-bonding areas Z described above, and the center area R3 arranged at the width center of the paper web PW. Regions R1-R3 are shown in FIG. In FIG. 10, the adhesive surface is indicated by reference numeral S.

  In order to clarify the correspondence between the side regions R1 and R2 and the above-described perforation row 16 and the correspondence between the center region R3 and the above-described center position CP, FIG. 10 shows a double of the paper web PW and the double filter cigarette WFC. The width paper WP is also shown. Further, as is apparent from FIG. 10, the regions R1 to R3 are formed in stripes in the adhesive surface S of the paper web PW, and extend parallel to each other along the longitudinal direction of the paper web PW.

  In order to form the adhesive surface S described above, a circumferential groove 52 is formed on the outer peripheral surface of the glue transfer roller 48 as shown in FIG. 11, and this circumferential groove 52 extends over the entire circumference of the glue transfer roller 48. Can receive glue. The glue in the circumferential groove 52 is transferred from the glue transfer roller 48 to the back surface of the paper web PW at the application position (position where the glue layer is formed), whereby the aforementioned adhesive surface S is formed.

On the other hand, three circumferential lands 54, 56, 58 corresponding to the regions R 1 to R 3 are arranged in the circumferential groove 52, and these circumferential lands 54, 56, 58 are circumferential when viewed in the width direction of the glue transfer roller 48. Each is located in the central region of the groove 52. The circumferential lands 54, 56, and 58 extend in the circumferential direction of the glue transfer roller 48, preferably over the entire circumference of the glue transfer roller 48, and form a part of the outer peripheral surface of the glue transfer roller 48. Even if glue adheres to the circumferential lands 54, 56, 58, the glue on the circumferential lands is removed by a scraper (not shown), and the circumferential lands 54, 56, 58 are used for transferring the glue to the paper web PW. Never used.
That is, in the case of this embodiment, the circumferential lands 54, 56, and 58 cooperate with the circumferential groove 52 to realize a first mechanism (first process) that forms the bonding surface S except for the regions R1 to R3.

  As described above, when the two perforated rows 16 are formed on the double-width paper WP of the double filter cigarette WFC by laser light irradiation, dust is generated from the double-width paper WP and the double-length filter WF, and these dusts are surrounded by the surroundings. Even if scattered, the side regions R1 and R2 of the double-width paper WP where the perforated rows 16 are formed have not been applied with glue, so that the dust does not have adhesiveness. Therefore, even if the dust contacts the outer surface of the double filter cigarette WFC and the filter cigarette FC or the outer surface of each machine element of the manufacturing machine, the dust does not adhere to these outer surfaces.

  Even if dust remains on the outer surface described above, these dust can be removed naturally during the transfer process of the double filter cigarette WFC or filter cigarette FC, or can be easily achieved by blowing air on the outer surface, for example. It can be removed.

  Since the paper web PW is formed with not only the side regions R1 and R2 but also the center region R3, when the double filter cigarette WFC is cut into two filter cigarettes FC, the cigarette cutting device 42 is in the center region. Double filter cigarette WFC can be cut with R3. In this case, since no glue is applied to the center region R3, the glue does not adhere to the cutting blade of the cigarette cutting device 42, and the sharpness of the cutting blade does not deteriorate due to the adhesion of the glue.

Further, the glue transfer roller 48 can intermittently form a non-adhesive transverse region R4 in addition to the regions R1 to R3 described above on the back surface of the paper web PW. Such a crossing region R4 crosses the paper web PW and is arranged at intervals along the longitudinal direction of the paper web PW. The transverse region R4 is also formed by a plurality of transverse lands (not shown) of the glue transfer roller 48, and these transverse lands cross the outer peripheral surface of the glue transfer roller 48 and are equally spaced in the circumferential direction. Has been placed.
The interval between two adjacent transverse regions R4 matches the length (circumferential length) of the double-width paper WP, whereby the web cutting device 36 described above cuts the paper web PW at the transverse region R4, and double-width paper Form WP. Therefore, glue does not adhere to the cutting blade of the web cutting device 36.

12 and 13 show a modified glue applying device 34 '.
The glue transfer roller 48 ′ of the glue application device 34 ′ applies a thermosetting glue to the entire back surface of the paper web PW except for the aforementioned transverse region R 4 to form an adhesive surface S.
In this case, the glue applying device 34 ′ further includes a disabling mechanism (second mechanism) 60 that partially invalidates the adhesive force of the adhesive surface S. The disabling mechanism 60 includes the glue transfer roller 48 ′ and the web cutting device. 36.

As shown in FIG. 13, for example, the disabling mechanism 60 includes a heater 61 as a curing device, and the heater 61 includes a heater block 62. The heater block 62 is positioned on the back side of the paper web PW traveling on the web supply path 32 and incorporates a heating element (not shown). Note that FIG. 13 is shown with the adhesive surface S of the paper web PW facing upward.
Three heating projections 64, 66, and 68 are integrally formed on the surface of the heater block 62 facing the back surface of the paper web PW. These heat generating protrusions 64, 66, and 68 extend in parallel to each other over a predetermined length in the longitudinal direction of the paper web PW, and are positioned in the vicinity of the bonding surface S of the paper web PW.

  When the paper web PW passes through the heater block 62, the heat generating protrusions 64, 66, and 68 apply heat to the corresponding portions of the bonding surface S to heat them, and harden the glue forming the bonding surface S to the part (second). process). Therefore, as shown in FIG. 14, side and center regions R1 'to R3' corresponding to the aforementioned side and center regions R1 to R3 are formed on the paper web PW, respectively. Since the glue forming these regions R1 'to R3' is cured by heating, that is, dried, the regions R1 'to R3' no longer have adhesiveness.

  Therefore, even if the perforated row 16 is formed in the side regions R1 ′ and R2 ′ that form the non-adhesion zone Z, the generation and scattering of dust having adhesiveness is the same as in the case of the side regions R1 and R2 described above. The side regions R1 ′ and R2 ′ provide the same advantages as the side regions R1 and R2. Needless to say, the center region R3 'has the same advantages as the center region R3.

On the other hand, when the glue is an ultraviolet curable adhesive, the invalidation mechanism (curing device) 60 described above can include an ultraviolet irradiator 63 as shown in FIG. The ultraviolet irradiator 63 has exit windows 64 ′, 66 ′, 68 ′ corresponding to the heat generating protrusions 64, 66, 68 described above. The ultraviolet irradiator 63 irradiates the adhesive surface S with ultraviolet rays through the exit windows 64 ′, 66 ′, 68 ′, and partially cures the adhesive on the adhesive surface S, thereby forming the side and center regions R 1 ′ to R 3 ′. To do. Also in this case, generation and scattering of dust having adhesiveness are similarly avoided.
Needless to say, the crossing region R4 ′ corresponding to the above-described crossing region R4 can also be similarly formed by heating the bonding surface S or irradiating the bonding surface S with ultraviolet rays. Furthermore, the invalidation mechanism (curing device) 60 can use electromagnetic waves including visible light, infrared light, or high frequency instead of ultraviolet light.

FIG. 16 shows a filter cigarette FC ′ according to the second embodiment of the present invention.
In describing the filter cigarette FC ′, the same components as those of the filter cigarette FC of the first embodiment are denoted by the same reference numerals, description of these components is omitted, and only differences from the filter cigarette FC are described. Is described below.

  The filter cigarette FC 'includes the dual filter 12' instead of the above-described filter 12, that is, a plane filter. The dual filter 12 ′ includes, for example, a plane filter element 70 and a charcoal filter element 72. The plane filter element 70 has the same structure as the filter 12, but has a length shorter than the length of the filter 12, for example. On the other hand, the charcoal filter element 72 includes a plane filter element similar to the plane filter element 70 and a large number of activated carbon particles 74 distributed inside the plane filter element.

Further, the dual filter 12 ′ has a formed paper 76, and the formed paper 76 is wound around the plain filter element 70 and the charcoal filter element 72, thereby integrally connecting the filter elements 70 and 72.
The filter cigarette FC ′ has, for example, two perforation rows 16 ′ instead of the perforation row 16 described above. The perforations 18 ′ forming these perforation rows 16 ′ open to the outer peripheral surface of the chip paper 14 corresponding to the charcoal filter element 72 as apparent from FIG. 17, while penetrating the chip paper 14 and the forming paper 76, The charcoal filter element 72 extends vertically to the axis A to the inside. In this case, the laser emitter 46 of the laser perforation apparatus 40 emits laser light perpendicular to the axis A.

The above-described perforated row 16 ′ is also arranged in the non-adhesive zone Z, and this non-adhesive zone Z can be formed using the paste applying device 34 of the first embodiment or the paste applying device 34 ′ of the modified example described above. is there.
According to the filter cigarette FC ′ described above, when this filter cigarette FC ′ is smoked by the user, outside air is introduced into the charcoal filter element 72 of the dual filter 12 ′ through each perforation 18 ′ of the perforation row 16 ′. The outside air thus introduced dilutes the mainstream smoke of the filter cigarette FC ′, thereby providing the user with a light smoking feeling.
In this case, the amount of air introduced into the charcoal filter element 72 through the perforations 18 ′ can be easily adjusted by the laser perforation device 40, depending on the number, size and depth of the perforations 18 ′.

On the other hand, in the case of the filter cigarette FC of the first embodiment described above, the total amount of mainstream smoke delivered into the user's mouth is represented by Qa, and the amount of mainstream smoke delivered from the perforations 18 is represented by Qe. In this case, the ratio of Qe to Qa, that is, the distribution ratio Qe / Qa of mainstream smoke greatly affects the flavor and taste of the filter cigarette FC.
Therefore, when manufacturing the filter cigarette FC, it is necessary to control the number, size, and depth of the perforations 18 that should match the distribution ratio Qe / Qa of the mainstream smoke to a desired value. Accurate measurement of the distribution ratio Qe / Qa is essential.

As shown in FIG. 18, the above-described Qa can be expressed by the following equation.
Qa = Qc + Qe = Vt + Vp + Vf
here,
Qc: The amount of mainstream smoke sent from the suction end face 12e of the filter cigarette FC,
Vt: the amount of air introduced into the cigarette 10 from the tip of the cigarette 10,
Vp: the amount of air introduced into the cigarette 10 through the cigarette 10 wrapping paper,
Vf: The amount of air introduced into the filter 12 through the perforation row 18 ′. Note that the filter cigarette FC of the first embodiment does not have the perforation row 18 ′. Assume that you have. This means that the filter cigarette FC of the first embodiment may also have a perforation row 18 ′ in addition to the perforation row 16.

FIG. 19 schematically shows a measuring device 78 for the distribution ratio Qe / Qa of mainstream smoke. The measuring device 78 will be described below.
The measuring device 78 includes a filter socket 80, and the filter socket 80 has a cylindrical shape. The filter cigarette FC can be inserted into the filter socket 80 with the mouth end of the filter 12 as the head.
Two seal rings 82 and 84 are attached to the inner peripheral surface of the filter socket 80, and these seal rings 82 and 84 have elasticity. One seal ring 82 is positioned on the bottom side of the filter socket 80, and the other seal ring 84 is positioned on the open end side of the filter socket 80.

Therefore, as apparent from FIG. 19, when the filter 12 is inserted into the filter socket 80, two chambers 86 and 88 are formed in the filter socket 80. The chamber 86 is defined hermetically through a seal ring 82 between the mouth end surface 12 e of the filter 12 and the bottom of the filter socket 80. On the other hand, the chamber 88 is hermetically defined so as to surround the filter 12 between the seal rings 82 and 84, and the perforation row 18 is positioned in the chamber 88.
Branch paths 90 and 92 extend from the chambers 86 and 88, respectively, and these branch paths 90 and 92 are connected to the suction path 94. The suction path 94 is connected to a suction pump 98 via a mass flow controller 96. When the suction pump 98 is activated, the mass flow controller 96 sets the flow of suction air in the suction path 94 to 1050 ml / min.

On the other hand, the pressure regulator 100 and the valve 102 are sequentially arranged on the branch path 90 from the chamber 86 side, and the flow meter 104 is arranged on the branch path 92. Here, the pressure regulator 100 generates a pressure loss equivalent to the flow meter 102.
Further, the branch paths 90 and 92 are connected to each other via a bypass path 106 upstream of the pressure regulator 100 and the flow meter 104, and a valve 108 is disposed in the bypass path 106.

The distribution ratio Qe / Qa of mainstream smoke is measured according to the following procedure.
Step 1:
Valve 106 is opened while valve 102 is closed. In this state, the air in the chambers 86 and 88 is sucked together, and the flow rate Qa is measured by the flow meter 104.
Step 2:
Valve 106 is closed while valve 102 is opened. In this state, the air in the chamber 88 is sucked and the flow rate 104 measures the flow rate Qe.
Step 3:
Based on the measured flow rates Qa and Qe, the distribution ratio Qe / Qa of mainstream smoke is calculated.

  Since the pressure regulator 100 that generates a pressure loss equivalent to the flow meter 104 is disposed in the branch path 90, the suction pressure in the chambers 86 and 88 is measured when the flow rates Qa and Qe are measured in steps 1 and 2. It will be the same. Therefore, the flow rates Qa and Qe can be measured under the same conditions, and the flow rates Qa and Qe, that is, the distribution ratio Qe / Qa of mainstream smoke can be accurately measured.

The present invention is not limited to the above-described first and second embodiments and the paste application device 34 'according to the modification, and various modifications are possible.
For example, in the above-described embodiment, the double filter cigarette WFC is a perforation target, but the filter cigarette FC may be a perforation target. Further, the perforation rows 16, 16 ′ may be formed at separate perforation positions. For example, when the perforation row 16 is formed in one of the double filter cigarette WFC and the filter cigarette FC, the perforation row 16 ′ is formed in the other of the double filter cigarette WFC and the filter cigarette FC. Needless to say, the number and arrangement of the perforation rows can be arbitrarily selected.

Furthermore, the filter cigarette FC does not necessarily require the perforation row itself, and may have at least one perforation. In this case, it is only necessary that the non-adhesive zone Z is spot-formed at the site of the paper web PW where the perforations are to be formed.
The adhesive surface S can also be formed by spraying glue from a nozzle instead of applying (transferring) glue, while the non-adhesive zone Z can also be used for chemicals instead of heat or the aforementioned electromagnetic waves. It can also be obtained by changing it.
Further, the filter cigarette is not limited to the above-described plane filter or dual filter, but can include a filter structure such as a triple filter or a recess filter, and various materials can be used as a filter material.
