    Abstract: Wrapper for cigarette manufacture includes transversely extending band regions applied by a printing technique, such as gravure printing. The band regions comprise starch, an anti-wrinkling agent such as 1,2 propylene glycol or glycerin, and optionally calcium carbonate. Any suitable printing technique can be used to apply the aqueous solution to the banded regions. The pattern of banded regions may be bands, stripes, two-dimensional arrays, undulated regions, and the like along and/or around the tobacco rod. The pattern can be applied in one or more layers. The pattern may be configured so that when a smoking article is placed on a substrate, at least two longitudinal locations along the length of the tobacco rod have film-forming compound located only on sides of the smoking article not in contact with the substrate.

    Abstract: One embodiment of the invention provides a method and apparatus for manufacturing a smoking article. The apparatus comprises a conveyor (60) for a tobacco rod (65). The direction of conveyance is parallel-to a central longitudinal axis of the tobacco rod (65). The apparatus further comprises an applicator (72) for applying a liquid additive to the tobacco rod (65) on the conveyor (60). The applicator (72) is configured such that liquid additive received into the tobacco rod (65) has a distribution in a cross-sectional plane perpendicular to the central longitudinal axis of the tobacco rod (65) that is substantially symmetrical about the central axis. In one embodiment, the applicator (65) comprises a plurality of dispensing heads (75A, 75B) disposed around the tobacco rod (65). In another embodiment, the applicator (72) includes a plough (91) for creating a furrow within the tobacco rod (65) and a dispensing head (92) for dispensing additive into the furrow.

  • Publication number: 20090277466
    Abstract: A method and apparatus of manufacturing a web which is striped with add-on material, comprising: a first slurry supply which forms a sheet of base web and moves the sheet along a first path; a second slurry supply; and a moving orifice applicator operative so as to repetitively discharge the second slurry upon the moving sheet of base web. The moving orifice applicator includes a chamber box arranged to establish a reservoir of the second slurry across the first path, an endless belt having orifice groups, the endless belt received through the chamber box, and a drive arrangement operative upon the endless belt to continuously move the orifices along an endless-path and repetitively through the chamber box. The orifices communicate with the reservoir to discharge the second slurry as bands of add-on material to the base web. Orifices within the orifice groups can be spaced relative to one another to define bands of add-on material having a relative minimum in thickness or to define spaced apart bands.

  • Publication number: 20090065012
    Abstract: Cigarettes are manufactured using modified automated cigarette making apparatus. Those cigarettes possess smokable rods having paper wrapping materials having additive materials applied thereto as patterns. The additive material can be applied as a coating formulation in an off-line manner to a continuous paper sheet web that is later used for cigarette manufacture. The additive material can be applied as a coating formulation in an on-line manner to continuous paper web moving through an operating cigarette making machine. The coating formulation is applied to the paper web using roll applicator techniques, ink jet printing techniques or electrostatic precipitation techniques. Liquid coating formulation are curable, and are virtually absent of solvent or liquid carrier. Radiation, such as ultraviolet or electron beam radiation, is used to solidify and fix polymerizable liquid components of the coating formulation that have been applied to the paper web.

  • Patent number: 7296578
    Abstract: An additive material is applied to a substrate, such as a paper web used as a wrapping material for cigarette manufacture. A predetermined pattern of additive material is applied to the outer surface of the wrapping material of a formed cigarette, and most preferably of a formed filtered cigarette. In particular, an application system for applying additive material of a controlled type, in a controlled manner and in a controlled location on the wrapping material of a formed two-up filtered cigarette rod is located within a tipping machine. During controlled rotation of each such formed rod (e.g., due to cooperation of (i) a roll drum, and (ii) cooperating roll block and star drum), additive material is applied to the outer surface of a desired location of the wrapping material of each such rod.

  • Patent number: 7281540
    Abstract: Cigarettes are manufactured having smokable rods with paper wrapping materials having additive materials applied thereto as patterns. The additive materials can be applied to a continuous, moving paper web on a cigarette making apparatus using application apparatus possessing four rollers. One roller has a series of pockets to receive additive formulation and to define the pattern of the formulation on the paper. The additive material can be applied to a transfer roller in roll interaction with a pick-up roller. Roll interaction of the transfer roller with an application roller causes transfer of the additive material from the transfer roller to the application roller. Additive material from the application roller can be transferred to the paper web that passes between the application roller and a back-up roller. A radiant dryer can be used to dry the additive material applied to the paper web.
