  • the invention provides a method of producing tipping sheet or tipping paper for use in manufacturing a smoking article, such as a cigarette, cigarillo, or the like.
  • tipping sheet or tipping paper is typically employed during assembly of the smoking article to join a filter element to a tobacco rod element, after those elements have been pre-assembled separately.
  • the tipping sheet or tipping paper typically forms an outer layer of the smoking article, particularly at the filter element end region, with which a consumer makes physical contact during use.
  • WO 2013/090968 A1 is related to a lining paper of a filter cigarette.
  • a tipping paper can comprise a foil material having raised or grooved features at only a bonding area of the tipping foil so as to improve adhesiveness of glue applied to said area.
  • WO 2009/141217 A1 describes an apparatus and a method for making a cigarette having an embossing unit configured to emboss sheet material wrapped around smokable material.
  • a smoking article such as a cigarette, cigarillo, or the like, having the features recited in claim 1 is provided. Further, the invention provides a method of manufacturing a smoking article having the features recited in claim 10. In addition, the invention provides a method of producing tipping sheet or tipping paper for use in manufacturing a smoking article as recited in claim 13. Various advantageous and/or preferred features of the invention are recited in the dependent claims.
  • the invention provides a smoking article, such as a cigarette, cigarillo, or the like, comprising:
  • the inventors have been able to ensure that the adhesive bond which is formed in the bonding region of the tipping sheet is reliable, unobtrusive and consistent despite the presence of raised profile elements. Furthermore, however, the inventors have developed a configuration in which the adhesive bond formed is enhanced or improved by virtue of a greater bonding surface area provided in the bonding region. That is, the relationship between a height of the raised surface profile elements and the thickness of the adhesive enables the adhesive to cover a substantial amount of the outer surface in the bonding region of the tipping sheet.
  • the bonding region of the tipping sheet is a region in which the tipping sheet overlaps with itself when wrapped around at least part of the rod element of smokeable material and the filter element.
  • the bonding region is preferably elongate and extends in a longitudinal direction of the smoking article; for example, along an edge portion of the tipping sheet.
  • the tipping sheet is generally rectangular and is wrapped cylindrically around at least part of the rod element of smokeable material (i.e. the tobacco rod element) and at least part of the filter element. The tipping sheet is wrapped around and thereby encompasses or envelops at least part of the filter element so that the tipping sheet (e.g.
  • a band or strip of tipping paper physically and mechanically attaches or connects the filter element to the tobacco rod element.
