Definitions

  • the present invention relates to a cigarette filter rod for a paper filter attached to a tip end of a cigarette, and its producing method and apparatus. (see GB-A-1 250 170).
  • the filters to be attached to ends of cigarettes are catergorized into a paper filter type using paper (i.e., pure pulp) as a filter material and an acetate filter type using acetate fiber as a filter material.
  • the means i) is used for the acetate filter material but is not applicable to the paper filter material.
  • the filter material is throttled into a thin rod shape and then the subsequent step of lapping the filter material with the paper.
  • the active charcoal particles would be dispersed away from the filter material.
  • the feeding rate of the filter material would be increased, the active charcoal particles would be dispersed due to the feeding operation of the filter material. In other words, if the feeding rate would be increased, the dispersion of the acrive charcoal particles would be further accelerated.
  • the binders applied to the paper filter material would be attached to the surfaces of the active charcoal particles to considerably reduce the deodorising effect of the active charcoal particles.
  • a primary object of the invention is to overcome the above-noted difficulties inherent in the prior art.
  • Another object of the invention is to provide a cigarette filter producing technique that does not reduce the deodorant effect of the active charcoal particles and the flavor effect of the flavor particles and which prevents the dispersion of the active charcoal particles and/or flavor granular particles.
  • a method for producing a cigarette filter rod comprising the following steps of: dispersing active charcoal particles to a paper filter material continuously fed; subsequently folding said filter material with its edge portions being overlapped with each other; gathering, into a thin rod shape, the filter material that laps therein the active charcoal particles with its folded edge portions; and subsequently coating the thin rod-shaped filter material with a coating material to thereby produce a paper filter rod with active charcoal particles.
  • an apparatus for producing a cigarette filter rod comprising: a paper filter material feeding means for continuously feeding a paper filter material; an active charcoal particles dispersion section for dispersively applying active charcoal particles to the paper filter material; a filter material folding means for folding both edge portions of the paper filter material inwardly so as to lap the active charcoal particles dispersively applied onto the paper filter material; a forming means for gathering, into a thin rod shape, the filter material that laps therein the active charcoal particles; and a winding means for winding the filter material, gathered into the thin rod-shaped paper filter material, with a lapping paper.
  • a paper cigarette filter rod for being continuously connected to an end of a cigarette, characterized in that creases for absorbing nicotine and tar are formed in an interior of the filter rod, and that active charcoal particles for deodorising odors of tobacco leaves are held in the creases only by a resiliency of a filter material and by the creases.
  • a method for producing a cigarette filter rod comprising the following steps of: dispersing granular material, which stimulates human taste, to a paper filter material continuously fed; subsequently folding the filter material with its edge portions being overlapped with each other; gathering, into a thin rod shape, the filter material that laps therein the granular material with its folded edge portions; and subsequently coating the thin rod-shaped filter material with a coating material to thereby produce a paper filter rod with granular material.
  • Figs. 1 through 9 show one example for producing cigarette filter rod with active charcoal particles 3 diffused or dispersed into a filter material 1.
  • the paper filter material 1 is wound in an original roll 5 from which the paper filter material 1 is continuously drawn.
  • a craping station 6 serves to continuously form longitudinal thin creases in the paper filter material 1.
  • a pair of craping rolls 7 each having a number of circumferential grooves and projections on their outer periphery are rotatably mounted in a suitable position.
  • the longitudinal thin creases 2 are formed in the filter material 1 by means of the craping section 6 so that an air ventilation resistance thereof is increased when the filter material 1 is formed into a rod and therefore, a filtration efficiency of the filter for the nicotine and tar is also increased.
  • An active charcoal particle dispersing section serves to disperse active charcoal particles.
  • a hopper 10 is provided above the rotary dispersion roller 9.
  • a guide case 11 is provided in front of the rotary dispersion roller 9. The active charcoal particles 3 fed in the hopper 10 is uniformly applied to the paper filter material continuously fed below the rotary dispersion roller 9.
  • Fig. 9 shows another embodiment of the active charcoal particle dispersing section 8 in which the guide case 11 is obliquely provided at a predetermined angle.
  • active charcoal particle dispersing section 8 is not limited to those shown in the drawings but any structure may be used as the dispersing section as far as it is possible to disperse the active charcoal particles 3 immediately before the commencement of the folding operation of the paper filter material 1.
  • a filter material folding section 12 serves to fold the paper filter material 1.
  • a retainer plate 13 adjustably suspended from a support rod 25 projecting from a machine body 27 is provided horizontally through a gap corresponding to a thickness of the paper filter material 1 above an upper surface of a receiving plate 26 projecting from the machine body 27.
  • a pair of curved rods 14 which are obliquely close to each other on the front side of the retainer plate 13 are provided on a mount rod 28 projecting from the machine body 27 as best shown in Fig. 3.
  • a curved portion 14' of each curved rod 14 is obliquely provided so as to depress downwardly both edge portions of the paper filter material 1 which has been subjected to the creases or steps by the roller 17.
  • a pair of clamping thin plates 22 are provided on both sides on the upper surface of the retainer plate 13 for clamping, inwardly gathering and folding the edge portions 1' depressed downwardly and pressed inwardly by the curved portions 14' of the curved rods 14.
  • the pair of clamping thin plate 22 cause both the edge portions 1' of the paper filter material 1 raised inwardly by the curved portions 14' of the curved rods 14 to be well drawn inwardly to thereby continuously form overlapping portions along the edge portions of the filter material 1.
  • the clamping thin plates 22 are arranged so as to intersect with each other from the front side (upstream side) to the rear side (downstream side) of the retainer plate 13 (as best shown in Fig. 2) and so as to increase a distance between the clamping plates 22 and the retainer plate 13 toward the rear side (downstream side) for retaining the overlapping portion 24 in cooperation with the retainer plate 13.
  • Reference numeral 31 denotes a mount support portion and numeral 32 denotes an introduction window for the active charcoal particles 3.
  • Reference numeral 15 denotes a forming section for forming into a thin rod-shaped bundle the paper filter material 1 which has been dispersively coated with the active charcoal particles 3 and which lapps the active charcoal particles 3 by the curved rods 14 and the clamping thin plates 22.
  • the filter material 1 is passed through a sleeve portion 16 which is gradually tapered forwardly, so that the filter material 1 is continuously throttled to form a thin rod-shaped bundle.
  • Reference numeral 18 denotes a lapping section for continuously coating the thin rod-shaped filter material 1 with a lapping paper 19.
  • Reference numeral 20 denotes a wind roll of the lapping paper 19
  • numeral 21 denotes a pressure indicator of filter feeding air
  • numeral 29 denotes a cutter section
  • numeral 30 denotes a filter rod.
  • Longitudinal thin creases 2 are formed in the paper filter material 1 continuously drawn from the original roll 5 through the craping section 6 and are fed into the filter folding section 12.
  • the longitudinal thin creases 2 serve as final creases formed in the interior of the filter rod.
  • the opposite edge portions of the filter material 1 are inwardly raised by the curved portions 14' of the curved rods 14. Subsequently, the active charcoal particles 3 are dispersed through the guide case 11 from the rotary dispersion roller 9 located in the upper portion. Since the rear surfaces of the opposite edge portions 1' raised by the curved portions 14' are in contact with the inner edges of the clamping thin plates 22, the clamping thin plates 22 are arranged so as to intersect with each other, and the distance between the clamping plates 22 and the retainer plate 13 is increased toward the rear side (i.e., the downstream side), the opposite edge portions 1' are drawn inwardly to each other by the feed of the filter material 1.
  • the edge portions 1' are overlapped to form the overlapping portion 24 which is fed in this state. Accordingly, the opposite edge portions 1' of the paper filter material 1 lap the active charcoal particles 3 (see Fig. 2) and are led to the sleeve portion 16 of the forming section 15. Thus, it is possible to overcome the problem that the active charcoal particles are dispersed outwardly when the feed rate of the filter material 1 is increased.
  • the lapping paper 19 laps the thin rod-shaped bundle of paper filter material 1 to form a continuous filter material containing the active charcoal. Thereafter, the filter is cut into a predetermined length in the cutter section 29 to complete the formation of the filter rod 30 containing the active charcoal.
  • the paper filter rod 30 is a filter in which the active charcoal particles 3 are held only by the resiliency of the paper due to the provision of the internal creases (longitudinal creases or crapes 2) and the throddle effect imparted in the forming section 15, and it is unnecessary to use the binders or the like.
  • the filter rod 30 is further cut and attached to the end of the cigarette for use as the cigarette filter.
  • flavor particles such as lemon flavor and peppermint flavor or powders such as dry fine granular powders of fruit juice which stimulate the human taste such palate or odor taste are used, the particles are not dispersed outside, and the flavor effect is not reduced in the filter rod with powders.
  • the step of applying binders to the paper filter material may be dispensed with. Accordingly, it is unnecessary to effect the binder drying step. Also, since the granular material such as active charcoal particles and flavor particles are delivered under the condition that the particles are lapped by the folded paper filter material even if the paper filter material is delivered at a high feed rate, there is no fear that the charcoal particles, flavor particles or the like would be dispersed to the outside. It is therefore possible to produce filter rods at a high speed production rate. Since no binders are attached to the surfaces of the active charcoal particles, the deodorant effect would not degraded and the flavor effect of the flavor material or the like would not deteriorate.
