Definitions

  • the banded regions described herein exhibit both low ignition propensity and reduced rates of self-extinguishment under free burn conditions.
  • the banded regions are preferably formed by printing, specifically gravure printing, as described in detail below.
  • the banded regions may comprise a slurry of highly refined fibrous cellulose (e.g. , fibers, fibrils, microfibrils, or combinations thereof) or other add-on material applied using various spray or coating techniques, including application techniques that utilize a moving orifice applicator at the forming section of a paper-making machine as described in commonly owned US 5 997 691 and US 6 596 125 .
  • the second zone may include perforations which preferably are filled with an occluding material which melts or is evaporated when the burning coal approaches the banded region to thereby provide the second zone with increased permeability.
  • Total weight of add-on material for the banded region preferably lies in the range of 0.5 grams per square meter (g/m 2 ) to 15 g/m 2 , more preferably in the range of from 0.5 g/m 2 to 3 g/m 2 , even more preferably In the range of from 0.5 g/m 2 to 1.5 g/m 2 , approximately.
  • Conventional cigarette paper is permeable, with the permeability commonly designated in CORESTA, which measures paper permeability in terms of volumetric flow rate (cm 3 /sec) per unit area (cm 2 ) per unit pressure drop (cm of water).
  • the first and third zones preferably have a greater basis weight In grams per square meter than the intermediate second zone; for example, the basis weight in grams per square meter of the first and third zones may be at least twice the basis weight in grams per square meter of the second zone.
  • the second zone may comprise a gap.
  • the term "gap" refers to a discrete area of a banded region, between the first and third zones, lacking any permeability reducing add-on material ( i.e. , containing no layers of permeability reducing add-on material).
  • the wrapper may comprise iron oxide at the location of the second zone.
  • the second zone preferably has a greater permeability than the first and third zones.
  • Non-banded areas of the base web preferably do not comprise permeability reducing add-on material.
  • the transverse banded region may comprise greater than three zones.
  • the transverse banded region may comprise, for example, five zones, with the second and fourth zones separating the first, third and fifth zones and the wrapper having greater permeability along the second and fourth zones than along the first, third and fifth zones.
  • the at least one transverse banded region can be free of fillers and optionally at least one of the zones is formed at least in part from an add-on material which includes a filler.
  • the add-on material is preferably uniform across the first and third zones.
  • the first and third zones are outward of the second zone, and the overall wrapper structure at the second zone has a greater permeability compared to the overall wrapper structure at the first and third zones.
  • the wrappers of the invention are preferably supplied on bobbins and it is preferred that the wrapper on the bobbin comprises evenly spaced apart transverse banded regions or a repeating series of transverse banded regions.
  • first and third zones of add-on material 11, 13 may each be, for example, about 3 mm wide, and the second zone 12 may be, for example, about 1.5 mm or 2 mm wide.
  • the first and third zones of add-on material 11, 13 preferably comprise multiple layers of add-on material, such as, for example, two, three or four layers of add-on material.
  • the add-on material is preferably uniform across the first and third zones 11, 13.
  • FIG. 2 illustrates a smoking article having two banded regions 20 on a base web 100, each comprising first, third and fifth zones of add-on material 21, 23, 25 separated by second and fourth zones 22, 24, which may be in the form of gaps or In the form of reduced levels of add-on material.
  • the first, third and fifth zones of add-on material 21, 23, 25 may each be, for example, about 2 mm to 3 mm wide, and the second and fourth zones 22, 24 may each be, for example, about 1 mm to 2 mm wide. More preferably, the first, third and fifth zones of add-on material 21, 23, 25 may each be, for example, about 2 mm wide, and the second and fourth zones 22, 24 may each be, for example, about 1 mm wide or less.
  • the first and third zones of add-on material 31, 33 preferably comprise multiple layers of add-on material, such as, for example, two, three or four layers of add-on material, while the second zone of less add-on material 32 may comprise, for example, one or two layers of add-on material.
  • the add-on material is preferably uniform across the first and third zones 31, 33. Although second zones 32 are operative at a 1 mm width, the embodiment performs better at a 1.2 mm width or greater.
  • the slit banded paper having a permeability of 33 CORESTA provided 12mg CO (FTC).
  • FTC 12mg CO
  • the occlusive composition When the heated occlusive composition is applied, the occlusive composition is cooled or quenched and may be gelatinized. Thus, a portion of the free water in the occlusive composition becomes bound and unavailable to soak or migrate into underlying fibers of the base web. That binding of free water inhibits formation of waviness, cockling, and/or wrinkling in the base web.
  • Successive layers of the banded regions preferably have increased thickness relative to the first layer.
  • the banded regions provide a reduction in permeability to the underlying base web, which preferably restricts air flow needed to support combustion of the cigarette coal in the vicinity of the banded region. Further details of progressive multi-pass printing can be found in commonly owned U.S. Provisional Application No. 60/707,964 entitled PROGRESSIVE MULTI-PASS PRINT BANDED PAPER filed August 15, 2005.
  • the occlusive composition has a viscosity of about 1mPa ⁇ s (100 cP) at a temperature in the range of 40°C to 90°C so that the composition can be quenched on contact with the paper after gravure printing at that temperature.
  • the viscosity of the composition at room temperature is also important. The high viscosity at room temperature is needed so that the occlusive composition gels at room temperature.
  • the banded regions are applied to the wrapper using a successive gravure printing process.
  • Gravure printing operations are capable of precise registry of successive printing operations. Accordingly, gravure printing can be used to effectively print not only the first layer of the banded regions, but also the optional successive layers.
  • the successive layer(s) are coextensive with the previous layer(s) in both width and length ( i.e. , the layers do not have a stepped appearance); however, the successive layer(s) may have different basis weight In grams per square meter than the previous layer(s) or may comprise different add-on compositions.
  • successive layer(s) are preferably allowed to dry after the printing of each successive layer In accordance with well-known gravure printing techniques and conventional gravure printing systems.
  • the gravure printing process can be used immediately following paper manufacture, i.e. , at a printing station at a location near the end of the paper making machine.
  • the gravure printing process can be used in connection with reels carrying the wrapper onto which the banded regions are to be printed.
  • a reel of wrapper having a selected permeability and a selected basis weight is mounted so that the wrapper can be unspooled from the reel as a continuous base web.
  • the base web advances or passes through a first gravure printing station where the first layer of each banded region is printed on the paper.
  • the printing process may be applied to the felt side or the wire side of the paper, or both.
  • the wrapper passes through a second gravure printing station where a second layer of each banded region is printed on the corresponding first layer. Additional layers are applied in a similar manner as described.
  • the wrapper with the printed banded regions is wound up on a collection reel. The collection reel is then cut into bobbins. The bobbins are then used during manufacture of the desired smoking article in conventional tobacco rod making machines.
  • the apparatus at each of the gravure printing stations is essentially the same in its material aspects. Accordingly, it will suffice to describe one of the gravure printing stations in detail, it being understood that the other gravure printing stations have common features, unless otherwise noted.
  • a single pass technique can be used to make the banded paper instead of a multi-pass technique.
  • the apparatus includes a gravure cylinder or roller generally mounted for rotation around a horizontal axis.
  • the generally cylindrical surface of the roller is patterned (i.e. , with dots, lines, cells, etc.) in a suitable process to define a negative of the first layer of banded regions.
  • Conventional engraving (etching), chemical engraving, electronic engraving, and photo etching can be used to pattern the surface of the gravure cylinder.
  • the circumference of the roller is determined such that it is an integral multiple of the sum of the nominal distance between banded regions plus the banded region width. Thus, for each revolution of the roller, that integral number of first layers of the banded regions Is printed on the wrapper.
  • the multiple zones, for example, first, second and third zones, of the banded regions described herein may be applied in a single printing stage or multiple printing stages.
  • each zone which contains add-on material may be applied in a separate printing stage.
  • the first zone may be applied in a first printing stage and the third zone may be applied in a second printing stage.
  • the zones containing add-on material are applied using an appropriately patterned gravure cylinder or roller.
  • the gravure cylinder or roller is patterned so as to apply add-on material only in the first and third zones.
  • An impression cylinder is mounted for counter-rotation on an axis parallel to the axis of the roller.
  • the impression cylinder includes a nonmetallic resilient surface.
  • the impression cylinder is positioned between the roller and a backing roller, which is also mounted for rotation on an axis parallel to the axis of the roller and which counter-rotates relative to the impression cylinder.
  • One of the functions provided by the backing roller is stiffening the central portions of the impression cylinder so that the uniform printing pressure is attained between the roller and the impression cylinder.
  • the gravure cylinder or roller and the impression cylinder cooperate to define a nip through which the base web advances during the printing process. That nip is sized to pinch the base web as it moves between the gravure cylinder and the impression cylinder. The nip pressure on the base web ensures the correct transfer of the composition from the cylinder to the paper.
  • a reservoir contains the occlusive composition discussed above for forming banded regions on the wrapper.
  • the reservoir communicates with a suitable pump which is capable of handling the viscous occlusive composition.
  • the occlusive composition may then flow to a suitable heat exchanger where the temperature of the occlusive composition is elevated so that it lies in the range of about 40° to about 90°C so that the viscosity of the occlusive composition is adjusted to a level which is suitable for gravure printing.
  • viscosity for gravure printing usually needs to be less than about 200 cP.
  • the temperature of the occlusive composition is selected so that the viscosity is less than about 100 cP.
  • thermal conditioning While a separate heat exchanger Is disclosed, it may be desirable to provide thermal conditioning of the occlusive composition in the reservoir itself.
  • heating elements and stirring apparatus may be included in the reservoir to maintain the elevated temperature for the occlusive composition.
  • Placement of the thermal conditioning in the reservoir has the advantage of making pump selection and operating requirements simpler since the pump need not handle the occlusive composition at the higher viscosity associated with lower temperatures because the occlusive composition would already be heated and, therefore, at the lower viscosity.
  • thermal conditioning step occur at a temperature selected to avoid scorching the occlusive composition. Scorching can cause discoloration of the occlusive composition, and can affect the occlusive characteristics of the composition. Thus, scorching is to be avoided while the occlusive composition is subjected to thermal conditioning.
  • the heated occlusive composition is delivered to a suitable applicator that spreads the occlusive composition along the length of the gravure cylinder. That spreading step may be effected by pouring or spraying the occlusive composition onto the gravure cylinder, or simply by delivering the liquid occlusive composition to a bath of occlusive composition that collects at the bottom of the gravure cylinder, between the gravure cylinder and a collector.
  • the cylinder may be heated to prevent premature cooling of the composition.
  • the collector extends vertically around the gravure roller to a height sufficient to collect the bath, but to a height well below the top of the gravure cylinder.
  • occlusive composition can flow through a drain at the bottom of the apparatus back into the reservoir.
  • the occlusive composition circulates through the printing station and can be maintained at suitable printing viscosity by the thermal conditioning apparatus discussed above.
  • the occlusive composition adheres to the surface of the gravure cylinder, including in the impressions provided therein to define the banded regions. Further rotation of the gravure cylinder toward the nip moves the cylinder surface past a suitable doctor blade. The doctor blade extends along the length of the gravure cylinder and is positioned so that is wipes the surface of the gravure cylinder. In this way, those portions of the gravure cylinder that define the nominal spacing between adjacent banded regions is essentially wiped dean of the occlusive composition, while engraved portions of the gravure cylinder that define the banded regions themselves advance toward the nip full of the occlusive composition.
  • the occlusive composition is transferred to the surface of the wrapper.
  • the linear speed or velocity of the wrapper matches the tangential surface speed of both the gravure cylinder and the impression cylinder as the wrapper passes through the nip. In that way, slippage and/or smearing of the occlusive composition on the wrapper are avoided.
  • the thickness of the multilayer banded regions preferably is less than about 20% of the thickness of the base web, and may be less than 5% of the thickness of the base web.
  • the thickness of the first layer of the banded region applied in the first gravure printing station preferably is less than 4% of the base web thickness, and may be less than 1 % of the base web thickness. Thus, it is seen that the thickness of the first layer is small in relation to the thickness of the underlying base web.

  • wrapper A was a control, comprising a continuous, solid 6 mm printed banded region, having an add-on rate of 5.5x.
  • an add-on rate of 5.5x results in 8 g/m 2 to 9 g/m 2 of add-on material on a dry weight basis, and a basis weight of 26.5 g/m 2 for 6 mm banded regions with a 27 mm phase ( i.e. , the spacing from the leading edge of a banded region to the leading edge of the next banded region) applied to a base web with a basis weight of 25 g/m 2 .
