Definitions

  • the present invention relates to a filter cigarette having at least one perforation line in tipping paper thereof, a manufacturing machine for the filter cigarette, and a manufacturing method for the filter cigarette.
  • At least one perforation is formed in tipping paper of a filter cigarette, fresh air is introduced into a filter of the filter cigarette through the perforation.
  • the fresh air introduced in this way dilutes mainstream smoke of the filter cigarette in the filter of the filter cigarette, thereby offering a user a lighter feel of smoking.
  • This type of perforation is formed beforehand in a paper web used to form the tipping paper, and, for example, a laser beam can be used to form the perforation (see Paragraph 0047 of Patent Document 1 below).

  • the perforation is formed during the production process of the filter cigarette, it can extend into the filter by penetrating through the tipping paper and perforation size can be changed as well, making it easy to adjust the above-mentioned quantity of ventilation air.
  • a reverse side of the tipping paper is coated with glue on an entire region thereof, being formed as a bonding surface for both cigarette and filter. Therefore, if the perforation is formed in the filter by penetrating through the tipping paper as a result of laser beam irradiation, the laser beam irradiation causes combustion products (ashes) to be produced from the glue, tipping paper, and filter material and the combustion products scatter around as adhesive dust.
  • An object of the present invention is to provide a filter cigarette manufacturing machine, filter cigarette manufacturing method, and filter cigarette which can greatly reduce scattering of adhesive dust and thereby prevent quality of the filter cigarette from being degraded by the dust in forming perforations penetrating through tipping paper in a manufacturing process of the filter cigarette.

  • the glue layer forming device according to the present invention is provided with the above configuration, when the perforation is formed in the filter by the laser beam through the tipping paper in the manufacturing process of the filter cigarette, even if dust scatters around, the dust is not adhesive.
  • the manufacturing machine according to the present invention greatly reduces generation of adhesive dust in the process of perforation formation.
  • the dust which is not adhesive, can be removed easily from the outer surfaces of the filter cigarettes in a transfer process of the filter cigarettes in the manufacturing machine.
  • the present invention also provides a filter cigarette manufacturing method and a filter cigarette, whose details are as follows.
  • a manufacturing method comprises: a filter attaching step of producing a filter cigarette by receiving a cigarette, a filter, and tipping paper coated with glue and attaching the filter to the cigarette via the tipping paper; a laser perforation step of forming at least one perforation in the filter by irradiating the tipping paper of the filter cigarette with a laser beam in a process of transferring the filter cigarette from the filter attaching step to a succeeding stage, where the perforation extends into the filter by penetrating through the tipping paper; and a glue layer forming step of providing a bonding surface with respect to the cigarette and the filter by forming a glue layer on a reverse side of the tipping paper in a process of supplying the tipping paper to the filter attaching step, wherein the glue layer forming step includes a procedure for forming a non-adhesive region lacking adhesion on the reverse side of the tipping paper in order for the perforation to be formed in the non-adhes
  • a filter cigarette comprises: a cigarette; a filter placed next to one end of the cigarette; and tipping paper adapted to connect the cigarette and the filter with each other and provided with at least one perforation, wherein the perforation extends into the filter by penetrating through the tipping paper, the tipping paper includes a glue bonding surface and a non-adhesive region lacking adhesion, where the bonding surface is formed on a reverse side of the tipping paper and adapted to bond the tipping paper to outer circumferential surfaces of the cigarette and the filter, the perforation is provided in the non-adhesive region, and the non-adhesive region extends over an entire circumference of the tipping paper.

  • a filter cigarette FC according to a first embodiment of the present invention includes one cigarette 10.
  • a filter 12 is placed next to one end of the cigarette 10, and the cigarette 10 and filter 12 are connected with each other by being wound with tipping paper 14 coated with glue.
  • the tipping paper 14 covers the filter 12 and cigarette 10 by extending from a mouth-side end face 12e of the filter 12 to the one end of the cigarette 10.
  • the filter cigarette FC has at least one perforation in the tipping paper 14.
  • the tipping paper 14 has at least one perforation line 16.
  • the perforation line 16 is formed of a large number of perforations 18, distributed at intervals in a circumferential direction of the filter 12.
  • the perforation line 16 is placed near the mouth-side end 12e.
  • the individual perforations 18 in the perforation line 16 extend into the filter 12 by penetrating through the tipping paper 14 as is apparent from FIG. 2 while being inclined with respect to an axis A of the filter cigarette FC rather than being perpendicular.
  • each perforation 18 includes an outer end which opens to an outer circumferential surface of the tipping paper 14 near the mouth-side end face 12e and an inner end positioned closer to the cigarette 10 in the filter 12 than to the outer end of the perforation 18.
  • the filter 12 in FIG. 2 is shown as a plane filter.

  • the non-adhesive region Z is a ringshaped region extending over an entire circumference of the tipping paper 14 and is defined by two thin lines Lz added in FIG. 1 for convenience.
  • the tipping paper 14 is bonded to an outer surface of the filter 12 in a region other than the non-adhesive region Z. Also, because the non-adhesive region Z is not adhesive to the outer surface (wrapping paper 12w) of the filter 12, that part of a lap seam formed by lapping together opposite lateral ends of the tipping paper 14, which corresponds to the non-adhesive region Z, remains unbonded.
  • outer ends of the perforations 18 making up the perforation line 16 are all placed in the non-adhesive region Z. Therefore, when the perforation line 16 is formed by the manufacturing machine and manufacturing described later, even if dust such as described above scatters around, the dust is not adhesive. Thus, even if dust touches the outer surface of the filter cigarette FC, the dust does not adhere to the outer surface of the filter cigarette FC. Consequently, appearance of the filter cigarette FC is not marred and the perforations 18 are not clogged by duct adhesion to the outer surface of the filter cigarette FC and quality of the filter cigarette FC is maintained stably.

  • branch paths 90 and 92 are connected with each other through a bypass path 106 upstream of the pressure regulator 100 and flow meter 104, and a valve 108 is placed on the bypass path 106.
  • the distribution ratio Qe/Qa of the mainstream smoke is measured according to the following procedures.
  • the valve 108 is opened and the valve 102 is closed. In this state, air is sucked out of both rooms 86 and 88 and the flow rate Qa is measured by the flow meter 104.
  • the valve 108 is closed and the valve 102 is opened. In this state, air is sucked out of the room 88 and the flow rate Qe is measured by the flow meter 104.
  • the distribution ratio Qe/Qa of the mainstream smoke is calculated.
  • suction pressures in the rooms 86 and 88 become equal to each other during measurements of the flow rates Qa and Qe in procedures 1 and 2. This allows the flow rates Qa and Qe to be measured under same conditions making it possible to accurately measure the flow rates Qa and Qe, i.e., the distribution ratio Qe/Qa of the mainstream smoke.
  • the present invention is not restricted by the first embodiment, the second embodiment, or the glue application device 34' according to the variation, which have been described above, and various modifications are possible.
  • the double filter cigarette WFC undergoes perforation, but the filter cigarette FC may be subjected to perforation.
  • the perforation lines 16 and 16' may be formed at separate perforating positions. For example, when the perforation line 16 is formed in one of the double filter cigarette WFC and filter cigarette FC, the perforation line 16' will be formed in the other of the double filter cigarette WFC and filter cigarette FC. Also, needless to say, the number and layout of perforation lines may be selected as desired.
  • the filter cigarette FC it is not strictly necessary for the filter cigarette FC to have a perforation line itself, and it is enough that at least one perforation is provided. In this case, it is enough that a non-adhesive region Z is formed on a spot basis in that portion of the paper web PW in which a perforation is to be formed.
  • the bonding surface S can be formed by spraying glue from a nozzle instead of applying (transferring) the glue.
  • the non-adhesive region Z can be obtained as well by chemically changing the glue instead of using heat or the above-mentioned electromagnetic waves.
  • the filter cigarette is not limited to the above-mentioned plain filter and dual filter and may include a filter structure such as a triple filter or recessed filter. Besides, various materials are available for use as filter materials.
