Definitions

  • This invention relates to a tobacco product comprising a central bunch, a wrapper wound helically thereon, and a filter tip consisting of two aligned filter plug parts surrounded by mouthpiece papers which connect the filter tip with the wrapper covered bunch.
  • filter cheroots Similar tobacco products comprising only a single filter plug are known as "filter cheroots" and are produced by a technique which in substantial points resembles the production of filter cigarettes, and consequently at a high production rate.
  • a filter cheroot comprises both a similar binder and, around the binder, a wrapper applied by helically winding (so-called spiral rolling) of a ribbon- shaped tobacco sheet made of homogenized tobacco.
  • a drawback of known filter cheroots is that in practice is is impossible to obtain a perfect sealing between the wrapper and the mouthpiece paper. This is due to the fact that the tobacco, which has to be relatively moist in order to permit its processing, shrinks or contracts during storage after the manufacture whereas the mouthpiece paper does not alter its internal dimension. As a consequence of the overlapping and glueing of the edge zones of the wrapper there is also formed a helically extending furrow in the surface of the wrapper which in itself results in a leak which is further increased in response to the storage induced shrinking of the tobacco. During smoking the inevitable small leaks have the effect that an uncontrollable intake of false air which influences the enjoyment of smoking in an undesirable manner, takes place along the outer side of the wrapper, i.e. by-passing the tobacco filler.
  • the mouthpiece paper of the inner plug part surrounds the end portion of the bunch underneath the wrapper which extends to the outer end face of the inner plug part and is surrounded by the mouthpiece paper of the outer plug part.
  • a further advantage of the invention is that in mechanical respect the connection between the exterior mouthpiece paper and the wrapper is very stable due to the supporting effect exerted on the wrapper by the inner filter plug.
  • the necessary extra operations in the manufacturing schedule are readily compatible with the production rate obtainable in the manufacture of an otherwise similar prior art product.
  • DE-C-932,894 discloses a filter cheroot of the type referred to in the foregoing and including two aligned filter plug parts with separate mouthpiece papers which connect the filter tip with the helically wound bunch.
  • the mouthpiece paper of the filter plug which is first incorporated is wrapped around the end section of a bunch which has already been provided with a tobacco wrapper so that the paper surrounds the portion of this wrapper which abuts on the filter plug and is only supported by the filler tobacco of the bunch. Accordingly, the above drawbacks of filter cheroots having only one filter plug will also appear in the known tobacco articles with a double filter plug.
  • the outer plug part of the tobacco product of the invention may expediently be longer than the inner plug part and the possible perforation, mentioned above, of the exterior mouthpiece paper, which is intended to ensure a controllable ventilation, may then be located further from the outer end face of the filter so that the perforations are not so easily covered by the smoker's lips.
  • the ventilation may be obtained by a technique which is identical or substantially identical with a technique employed for manufacturing filter cigarettes which makes a high production rate possible.
  • the two filter plug parts may be made from the same filter material or from different filter materials. In the latter case it is possible, in a simple manner, to effect an adjustment of the total filter effect if this should prove expedient or necessary in order to comply with varying customers' taste desires.
  • a carbon filter and an acetate filter may be combined.
  • the invention also relates to a method of manufacturing the tobacco product from a continuously advancing rod consisting of a filler and a binder, which rod is severed into bunches around which a wrapper is helically rolled and to one end of which a filter tip comprising two plug parts with mouthpiece papers is applied.
  • the method is characterized in that the rod is severed before the wrapper rolling step, that a first filter plug is placed between two bunches and a first mouthpiece paper is wrapped around the filter plug and adjoining portions of the bunches, that a wrapper is rolled around the resulting double bunch which is then severed by a transverse cut through the first filter plug, that a second filter plug is placed between the bunches resulting from the severing and a second mouthpiece paper is wrapped around the second filter plug and adjoining portions of each wrapper covered bunch, and that the bunches which thus have been connected together, are separated by a transverse cut through the second filter plug.
  • Fig. 1g The manufacturing process is terminated by the article shown in Fig. 1g being severed in the middle and thus divided into two finished filter cheroots, the internal structure of which has been illustrated in Fig. 3 where, inter alia, the thicknesses of the wrapper and the mouthpiece papers have been somewhat exaggerated relative to the other dimensions, for the sake of clarity.
  • FIG. 3 how the wrapper 7 is efficiently supported from within by the inner filter plug 4a along a substantial part of the length of the end portion in which the wrapper is joined to the exterior mouthpiece paper 10a.
  • the inherent stability of the filter plug in respect of shape and dimensions results in a corresponding stability of the shape and dimensions of the outer surface of wrapper 7 at this location of the cheroot length, which ensures that the joint between the wrapper and the exterior mouthpiece paper 10a remains tight even during an extended period of storage.
