Referring to figs. 1 through 3,, has the paper package with gas permeability lower easy to use of banded regions separately than the banded paper of existing design for given CO level.For example, find in some cases, further do not change that the cigarette that then comprises the paper with 33 CORESTA gas permeabilities and 11mg CO (FTC) emission levels props up and will produce 15mg CO (FTC) if use the strap-like member of existing version.In order to offset this growth, the gas permeability of package must be elevated to about 46 CORESTA.Such change produces a plurality of consequences in design of cigarettes, for example influence suction number of times may weaken the machinability of paper etc.In contrast, the paper that separates banded regions of the band with 33CORESTA gas permeability provides 12mg CO (FTC).Thereby described herein have separately that the banded technology of banded regions helps using to the less strap-like member of CO level (FTC) influence.
With reference to Figure 4 and 5, other embodiment can comprise banded regions, wherein said district longitudinal extension but not circumferentially extend.More specifically, Fig. 4 has longitudinal extension but not circumferential district of extending corresponding to the banded region configuration of Fig. 2, and Fig. 5 has longitudinal extension but not circumferential district of extending corresponding to the banded region configuration of Fig. 3.
In a preferred embodiment, the ground floor of each banded regions preferably uses aqueous occlusive composition to form its complete extend past banded regions.The pantostrat of each banded regions (one or multilayer) can form by using identical aqueous film formation component or different aqueous components.For example, a plurality of layers can all comprise the layer that only contains starch, or a plurality of layer can comprise one or more layers and one or more layers (arranging with any order) of containing calcium carbonate that only contains starch.In the intaglio printing process, occlusive composition preferably is heated to its viscosity wherein and is in temperature in the range of viscosities that is suitable for intaglio printing.When applying the occlusive composition of heating, occlusive composition turns cold or cools off, but and gelatinization.Thereby the part of the Free water in the occlusive composition is restrained, and can not flood or move in the following end liner fiber.This effect of contraction of Free water prevents from the end liner to form and rises and falls, wrinkling and/or purse up.The pantostrat of banded regions preferably has the thickness of increase with respect to ground floor.Banded regions reduces the gas permeability of following end liner, and the required air of middle cigarette coal combustion flowed near banded regions was supported in so preferred restriction.The name of submitting in common 15 days all Augusts in 2005 is called the U.S. Provisional Application No.60/707 of PROGRESSIVE MULTI-PASS PRINT BANDEDPAPER, can find the further detailed content of gradual multipass printing in 964, its content is all incorporated this paper into it by reference at this.
The occlusive composition of using in the occlusive composition can be selected from the group that comprises starch, alginates, carrageenan (carrageenan), melon glue (guar gum), pectin and composition thereof.Preferably, occlusive composition comprises starch, more preferably comprises oxidized starch, and for example tapioca more specifically is the tapioca of oxidation.In an embodiment, occlusive composition does not for example preferably comprise fillers such as calcium carbonate, and described calcium carbonate will increase the burn rate through banded regions.In preferred enforcement, the occlusive composition that is used to print comprises the occlusive composition of water and percentage by weight about 20% to about 50%.Be under the higher concentration situation in occlusive composition, component can stand gelatinization when its temperature reduces fast.Thereby, Free water can be attached in the banded regions of printing.
At room temperature (about 23 ℃), the occlusive composition of high solids content have the viscosity that surpasses about 2mPas (200 centipoises (cP)), and are unsuitable for intaglio printing; But, temperature about 40 ℃ in about 90 ℃ of scopes, the viscosity of occlusive composition fully reduces to come as the intaglio printing component.For intaglio printing, be limited to about 2mPas (200cP) on the suitable viscosity.Most preferably, has the viscosity of about 1mPas (100cP) under the temperature of occlusive composition in 40 ℃ to 90 ℃ scopes, so that component cooling when can be after this temperature intaglio printing contacting with paper.At room temperature the viscosity of described component is also very important.Need the high viscosity under the room temperature, so that occlusive composition gel at room temperature.
Preferably, banded regions uses continuous gravure printing technique to be applied to package.The intaglio printing operation is the continuous printing operation of registration accurately.Therefore, intaglio printing not only can be used for the ground floor of printed banded regions effectively, and can be used for printing effectively optional a plurality of pantostrat.
In continuous gravure printing technique, preferably after ground floor is applied to end liner, advance to the second layer wherein use traditional continuous be applied to ground floor through the formula gravure printing apparatus before, allow described ground floor to use the proper device drying thereon.Preferably, the second layer and ground floor have same range as aspect length and the width, and still, the second layer can have different from ground floor to restrain the basic weight of every square metre of expression.The gel on colder ground floor of the occlusive composition of the second layer, and Free water does not move or is absorbed by paper.Preferably, allow the second layer before advancing to the continuous intaglio printing platform that wherein applies pantostrat (a plurality of), to use the proper device drying.Preferably, pantostrat (a plurality of) has common scope (being that described layer does not have stair-stepping outward appearance) with the layer of front aspect length and the width; But it is different to restrain the basic weight of every square metre of expression with the layer of front that pantostrat (a plurality of) can have, and maybe can comprise different annexing ingredients.Preferably, allow pantostrat (a plurality of) drying after each pantostrat is with known intaglio printing technology and traditional intaglio printing system printing.
And then gravure printing technique can use after the papermaking, promptly at the print station place near paper machine end position place.Alternately, gravure printing technique can be loaded with it on be printed with the package of banded regions spool be used in combination.For example, the package that a volume has selected gas permeability and selected basic weight being installed can get around package from spool as continuous end liner.
End liner advances or through the first intaglio printing platform, at this first intaglio printing platform, the ground floor of each banded regions is printed on the paper.Typography may be used on recto or reverse side or both.Next, package is through the second intaglio printing platform, and at this place, the second layer of each banded regions is printed on the corresponding ground floor.Other layers apply with similar manner as described.At last, the package with printed banded regions is wound on and collects on the spool.To collect spool then and be cut into bobbin.Bobbin props up in the process of making the expectation smoking article in the maker in conventional smoke and uses then.
At the equipment at each intaglio printing platform place substantially the same aspect its material.Therefore, of describing the intaglio printing platform in detail is just much of that, should understand, and other intaglio printing platform has common feature unless otherwise indicated.The paper that can use single pass technique manufacturing to have banded regions, but not multipass technology.
At the first intaglio printing platform place, described equipment comprises that common installation is used for gravure cylinder or the roller around horizontal rotational shaft.Usually the cylindrical surface of roller forms the negative film that pattern limits (promptly having point, line, cell etc.) the ground floor banded regions with suitable technology.Tradition engraving (etching), chemical engraving, electronic engraving and photoetching are used in the gravure cylinder surface and form pattern.The girth of roller is defined as being the integral multiple that nominal distance between the banded regions adds banded regions width sum.Thereby, whenever turning around for roller, this integer ground floor banded regions is printed on the package.
Use intaglio printing, though but each layer homogeneous of additional materials apply, each layer of additional materials does not need homogeneous to apply.For example, additional layer of material can be applied for and make the discontinuous part of described layer have the weight of the gram every square metre expression different with other zones of described layer.This can realize by for example using the additional materials with different basic weights print in independent print steps to have with the discontinuous part of other regional different basic weights of described layer.Alternately, additional layer of material can be applied to the discontinuous part that makes described layer and has degree of depth different with other zones of described layer.This can be for example realize by making gravure cylinder or roller form pattern, so that the discontinuous part that has with the described layer of other regional different depths of described layer to be provided.
A plurality of districts, for example first, second of banded regions described herein and the 3rd district can apply at single print steps or a plurality of print steps.When applying with a plurality of print steps, each district of containing additional materials can apply at independent print steps.For example, for the banded regions that contains first, second and the 3rd district, wherein only additional materials is contained in the first and the 3rd district, and first district can apply at first print steps, and the 3rd district can apply at second print steps.Alternately, when when single print steps applies, the described district of containing additional materials uses the gravure cylinder or the roller that suitably form pattern to apply.For example, for the banded regions that contains first, second and the 3rd district, wherein additional materials is contained in the only described first and the 3rd district, and gravure cylinder or roller formation pattern only are applied to additional materials in the first and the 3rd district.
Impression cylinder is mounted to and is being parallel to reverse rotation on the axle of roll shaft.In some applications, impression cylinder comprises nonmetal elastic surface.Impression cylinder is arranged between roller and the bearing roller (backingroller), and described bearing roller also is mounted to and is being parallel to rotation on the axle of roll shaft, and it is with respect to described roller platen reverse rotation.One of function that is provided by bearing roller is that the core of impression cylinder is strengthened, to obtain uniform squeegee pressure between roller and impression cylinder.Gravure cylinder or roller and impression cylinder cooperate and form roll spacing, and in printing process, end liner advances by described roll spacing.This roll spacing size is made extruding end liner when end liner is mobile between gravure cylinder and impression cylinder.Roll spacing pressure on end liner guarantee component from cylinder to the correct transfer printing of paper.
The reservoir splendid attire occlusive composition that is used on package, forming banded regions discussed above.Reservoir is communicated with the suitable pump of the occlusive composition that can handle viscosity.Occlusive composition can flow to suitable heat exchanger then, in described heat exchanger, the temperature of rising occlusive composition make its be in about 40 ℃ in about 90 ℃ of scopes, so that the viscosity of occlusive composition is adjusted to the level that is suitable for intaglio printing.As discussed above, the viscosity that is used for intaglio printing usually need be less than about 200cP.Preferably, the temperature of occlusive composition is chosen to make viscosity less than about 100cP.
Though disclose independent heat exchanger, can expect to be provided in the reservoir self thermal conditioning to occlusive composition.For example, can comprise that in reservoir heater block and mixing plant keep the temperature of the rising of occlusive composition.Thermal conditioning is set in reservoir has the pump of making selection and the simpler advantage of operation requirement, this is because owing to occlusive composition heats, and is in than low viscosity thus, thereby pump need not handled occlusive composition under the viscosity higher relevant with lower temperature.No matter thermal conditioning appears at still appears in the reservoir in the independent heat exchanger, and importantly thermal conditioning step avoids occlusive composition to burn under selected temperature.Burn and to make the occlusive composition variable color, and may influence the blocking performance of component.Thereby, when making occlusive composition stand thermal conditioning, avoid burning.
No matter where the thermal conditioning step carries out, the occlusive composition of heating is sent to the suitable applicator that occlusive composition is launched along the length of gravure cylinder.Deployment step can be by toppling over occlusive composition or being sprayed on the gravure cylinder or realizing by the liquid lock component is sent to the occlusive composition bath of collecting in gravure cylinder bottom between gravure cylinder and gatherer simply.But heated roller prevents component and cools off too early.
Usually, gatherer vertically extends to the height of enough collection body lotions around gravure roll, but extends to the height that is lower than the gravure cylinder top.When body lotion arrived the gatherer top, the discharge pipe that occlusive composition can be flowed through in device bottom flow back in the reservoir.Thereby occlusive composition circulates by print station, and can remain on suitable printing viscosity by thermal conditioning equipment discussed above.
When gravure cylinder rotation process applicator and/or body lotion, occlusive composition is attached to the gravure cylinder surface, is included in the recess that is used to form banded regions that wherein is provided with.Gravure cylinder is further rotated towards roll spacing cylinder surface is moved through suitable scraper.Scraper extends along the length of gravure cylinder, and is arranged so that the surface of its scraping gravure cylinder.By this way, those parts of nominal interval are scraped basically and are wiped clean and do not have occlusive composition between the qualification adjacent banded regions of gravure cylinder, and the engraving of the qualification banded regions of gravure cylinder part is from advancing towards roll spacing under the situation of filling occlusive composition.
When the surface of package and gravure cylinder moved through roll spacing, occlusive composition was transferred to package surface.When the roll spacing of package process, the tangential surface velocity coupling of the linear velocity of package or speed and gravure cylinder and impression cylinder.In this mode, avoid occlusive composition on package slip and/or smear.
The thickness of multilayer banded regions is about 20% less than end liner thickness preferably, and can be less than 5% of end liner thickness.The thickness of the ground floor banded regions that applies in the first intaglio printing platform is preferably less than 4% of end liner thickness, and can be less than 1% of end liner thickness.Thereby, can see that the thickness of ground floor is very little with respect to the thickness of following end liner.
