Definitions

  • This invention relates to a tipping assembly for an elongate smoking article.
  • it relates to a wrapped filter plug suitable for attachment to a cigarette or similar smoking article, and to a method of making such a wrapped filter plug.
  • Filter plug wrapping paper is com:::only attached to a filter plug by means of an adhesive such as polyvinyl acetate emulsion between the wrapping paper and the plug to avoid the plug becoming detached when suction is applied by the smoker.
  • an adhesive such as polyvinyl acetate emulsion between the wrapping paper and the plug to avoid the plug becoming detached when suction is applied by the smoker.
  • Low tar yields in cigarettes are usually achieved by providing high levels of filter ventilation, usually in excess of 60%.
  • One way of doing this is to use highly permeable plug wrapping paper enclosing the fibrous web of filter material.
  • a disadvantage of this is that when such wrapping paper is used on conventional filter making machines the adhesive may bleed through the pores or perforations in the wrapping paper and contaminate the machine, thus reducing running efficiency. This bleed through may also result in unpredictable variations in the overall level of ventilation obtained for a given combination of plugwrap and plug, which in turn would render unreliable the achievement of low tar yields.
  • a tipping assembly for an elongate smoking article comprising,
  • a tipping assembly for an elongate smoking article comprising,
  • the bonded fibres of the plug and the bondable fibres of the plug wrapper are preferably of identical composition.
  • the plug wrapper is preferably a multi-phase web including the bondable fibres as one phase, and is preferably a two-phase web.
  • the bonded fibres and the bondable fibres are preferably composed of cellulose acetate, and the plasticiser is preferably triacetin (glycerol triacetate).
  • a or the second phase of the plug wrapper is preferably cellulosic fibre.
  • the cellulosic fibres and the cellulose acetate component are preferably discrete phases, the cellulose acetate phase being adjacent the surface of the plug.
  • the plasticiser may be applied to the filter plug by spraying during filter manufacture.
  • the wrapping paper effectively adheres to the plug by virtue of the plasticiser used for bonding the cellulose acetate fibres of the plug bonding with the cellulose acetate component of the plug wrapper, and consequently there is no necessity for additional adhesion between plug and plug wrap.
  • FIG. 1 which is not to scale, shows a longitudinal cross-section through a portion of a wrapped filter plug 10 according to the invention.
  • the wrapped filter plug 10 comprises a plug 12 of cellulose acetate fibres that has been sprayed with triacetin (glycerol triacetate) which bonds together the cellulose acetate fibres.
  • the plug 12 is wrapped in a highly porous plug wrapper 14 comprising a fibrous sheet made of two components, which are, an outer layer 16 (relative to the plug 12) of cellulosic fibre, and an inner layer 18 of cellulose acetate fibres.
  • the wrapper 14 adheres to the plug 12 by virtue of the triacetin which enables the cellulose acetate fibres of the plug to bond to the cellulose.acetate fibres of the inner layer 18 of the wrapper.
  • the triacetin when sprayed onto the fibres, adheres to the surfaces of the fibres, does not exist to any substantial extent in a flowable liquid form between the fibres, and hence has no tendency to block pores or perforations in the plug wrapper.
  • the layers 16, 18 of the plug wrapper will be understood to be highly porous (e.g. above 100 K Filtrona units). Again, this cannot easily be shown in the drawing.
  • the wrapper comprises a single phase mixture of cellulose fibres and cellulose acetate fibres, as will be described.
  • a single phase wrapper sheet containing 30% by weight cellulose acetate in a blend of Abaca Hemp and softwood pulps was prepared.
  • Non-wrapped acetate filter rods were sprayed with tri a cetin to plasticise the surface material. strips of the single phase wrapper sheet were manually wrapped around the sprayed filter rods at various time intervals after spraying. The wrapped rods were then examined for any evidence of adhesion between plug wrap and filter rod. The results were as follows: Heating and compression were found to accelerate the plasticising effect and hence the adhesion.
  • Example 1 As for Example 1 except that, instead of non-wrapped acetate filter rods, conventionally formed filter rods (with existing plug wrap removed) were sprayed with triacetin. The remainder of the procedure of Example 1 was carried out. The results were similar to those of Example 1 except that the adhesion appeared to be stronger.
  • Sample D contained no binder in the plug wrap.
  • Cellulose acetate filter rods were produced containing 6, 8, 10, 13% by weight (wet tow) triacetin respectively, to a specification similar to that of a conventional leading king-size cigarette.
  • the samples of dual phase plug wrapping paper were applied to the filter rods.
  • the degree of adhesion was assessed by slitting the rods and subjectively assessing the relative degree of adhesion when pulling the plugwrap off the filter plug.
  • the rating is given on a subjective scale of 0 - 10, a rating of 10 denoting a definite tearing of fibres on pulling the plugwrap from the filter (i.e. a strong bond), and a rating of 5 denoting a definite adhesion but without tearing of fibres (i.e. a weak bond).
  • the ratings for samples A - D are given in Table 3.
  • a two phase wrapper sheet consisting of a web formed from long fibre cellulose derived from hemp, with cellulose acetate fibre deposited on top, was produced on an inclined wire paper making machine (known in the art) modified to allow the use of a dual headbox system.
  • the invention is found not to cause blockage of perforations in the plug wrap and therefore provides for excellent adhesion of the plug wrap to the filter plug in combination with reliable ventilation of the cigarette. Further, there is no bleed through of adhesive which could otherwise cause contamination and stoppage of filter and cigarette making machinery,
  • Plasticisers other than triacetin, such as triethylene glycol diacetate, and fibres bondable by the plasticiser, other than cellulose acetate, may be utilised in alternative embodiments within the scope of the invention.
  • the bondable fibres of the plug and the bondable fibres of the plug wrapper need not necessarily be of the same composition.
  • the cellulose fibre of the plug wrapper may be derived from a variety of sources, such as wood, hemp, flax, or bagasse.
