Definitions
- the present invention relates to a method and apparatus for producing a filter rod of filter material fibres, especially separated fibres, for the tobacco industry.
- the invention relates to a method and apparatus for forming filter rods comprised of individual or separated fibres, such as randomly-oriented fibres.
- Conventional filters for smoking articles typically comprise at least one substantially cylindrical segment of cellulose acetate fibres mixed with a plasticizer, such as triacetin.
- the cellulose acetate fibres come as continuous tow packed in a bale format which is then processed in a continuous bundle and sprayed with triacetin.
- the cellulose acetate fibres are formed into a continuous filter rod which is wrapped in a paper-based wrapper and then cut to create individual filter segments.
- different compounds can be added to the cellulose acetate to provide the filter rod with specific properties.
- the compounds may include adsorbents or flavours and may be provided in a particulate form, liquid form, or solid form.
- a filter for a smoking article may then be made of one segment of a filter rod, or from multiple segments of the same or of different filter rod compositions assembled together with at least one wrapping.
- the multiple segments may or may not be arranged with cavities or spaces between them.
- filters comprising a non-woven filter material, such as randomly oriented fibres.
- Such filters essentially comprise a rod of compacted filter material fibres, such as acetate and/or polyethylene fibres, preferably non-plasticized.
- Such filters can provide improved filtration efficiency compared to conventional plasticized cellulose acetate, in particular for smoking articles having a reduced length and/or a reduced circumference compared to standard or so-called "King size" smoking articles which have a length of about 68 to 72 mm and a circumference of about 23 to 25 mm .
- filters fabricated from separated or randomly oriented fibres for the tobacco industry are more difficult to manufacture than the conventional filters of plasticized cellulose acetate fibres due to the difficulty of controlling the volume or amount of fibres and any additives in single filter segments.
- the segments cut from filter rods of separated and/or randomly oriented fibres typically do not sustain or provide a reliable and regular shape at their cut ends, where the fibres and the additives may have a tendency to ravel out, tatter, or fray. This makes it very difficult to control consistency and reproducibility of the filter segments, not to mention their combination with other segments to form a smoking article filter.
- plasticizers with randomly oriented fibres
- the application of such plasticizers onto the fibres is typically by spraying and this would lead to a substantial contamination of the conventional filter rod manufacturing equipment, potentially causing damage to parts thereof .
- An object of the present invention is therefore to provide an improved method and apparatus for forming a filter rod which addresses the above problems.
- the invention provides a method and apparatus for forming a filter rod from separated and/or randomly oriented filter material fibres, as opposed to conventional plasticized cellulose acetate tow.
- a method of forming a filter rod of filter material fibres, especially separated and/or randomly oriented fibres, for the tobacco processing industry having the features set out in claim 1 is provided.
- the invention also provides an apparatus for forming a filter rod of filter material fibres for the tobacco processing industry as set out in claim 11.
- Various advantageous and/or preferred features are recited in the dependent claims.
- the invention provides a method of forming a filter rod from filter material fibres, especially separated fibres and/or randomly oriented fibres, for the tobacco processing industry, the method comprising: supplying separated filter material fibres to an inlet of a conveyor device,
- the separated filter material fibres are loose and/or randomly oriented fibres, it is firstly necessary to collect and form the fibres into a substantially continuous strand.
- This is achieved with the present invention by supplying the separated or loose fibres to a conveyor device and conveying those filter material fibres along the process path.
- at least one additive for instance a binder, may be added to the substantially continuous strand of the filter material fibres close to an outlet of a conveyor device. This provides an efficient delivery of the fibres in a controlled and consistent manner without risking fouling or contamination of the conveyor device.
- Filter rods produced from separated or randomly oriented fibres typically permit a higher additive load or content when compared with conventional cellulose acetate tow filters, which can be of particular interest for manufacturing filters with improved filtration properties for gas-phase components of tobacco smoke, especially when the additive in the randomly oriented fibres comprises an adsorbent, such as activated charcoal.
- an adsorbent such as activated charcoal
- the conveyor device is a suction conveyor device which includes one or more suction conveyor member, such as a suction belt, along the process path.
- the step of introducing the at least one additive to the strand preferably includes applying the additive to the strand of filter material fibres on the suction conveyor device, and in particular on the suction belt.
- the use of a binder in this way is not a simple matter because of the need to apply this binder uniformly to the fibres.
- the fibres are typically transported in a fluidized bed before being drawn onto the suction belt of the suction conveyor device to form a filter rod (similar to the manner in which tobacco rods are produced when manufacturing a smoking article) .
- an application of the binder to the fibres in the fluidized bed or in the suction conveyor can lead to fouling or extensive contamination of the filter rod making machinery and can make uniform application to the fibres difficult due to the air- stream in the fluidized bed and/or the under-pressure or vacuum in the suction conveyor. Rather counter-intuitively, these issues have been resolved or at least substantially ameliorated by introducing the binder to the strand of filter material fibres close to the outlet of the conveyor device.
- the step of introducing at least one additive comprises applying the additive in a final one- third, preferably in a final one-fifth, and more preferably in a final one-tenth of the process path defined by the conveyor device; i.e. at or upstream of the outlet.
- a suction conveyor device may typically be expected to have a length in a range of about 1 metre to 3 metres.
- the step of introducing at least one additive is carried out at least proximate to or adjacent the outlet of the conveyor device before the strand of filter material fibres exits the conveyor device. The application of the additive proximate or at the outlet, and therefore just before wrapping of the fibres to form the filter rod, ensures quick or rapid contact between the binder, fibres and wrapper material providing improved binding action to the fibres and improved stability of the filter rod manufactured.
- the introduction of the at least one additive comprises applying the additive in a substantially fluid or liquid form, preferably by spraying, onto the strand of filter material fibres on the process path.
- introducing the at least one additive preferably comprises applying or delivering the additive to the strand of filter material fibres via a gaseous carrier, such as compressed air or steam.
- the at least one additive preferably comprises one or more of: an aqueous composition, a flavouring compound, a binder compound, and a plasticizer.
- the at least one additive may alternatively or additionally be provided as an encapsulated compound or material .
- the spraying of the additive onto the continuous strand of fibres preferably occurs at an angle in the range of 0° and 90° to the conveying direction.
- the method includes locally moderating or reducing a vacuum or under-pressure applied to the strand of filter material fibres in the conveyor device at or immediately prior to introducing the at least one additive, e.g. a binder, thereto.
- the at least one additive e.g. a binder
- this can be achieved with one or more plate member or baffle arranged on the suction belt in the process path.
- the filter material fibres of the strand are relaxed and the at least one additive can better penetrate the strand. Also, there are lower additive losses due to a lower vacuum strength.
- the method of forming a filter rod further comprises heating the additive before and/or during the step of introducing the at least one additive.
- the step of supplying the filter material fibres to the inlet of the conveyor device includes delivering a mixture of filter material fibres (for example, of different fibres) to the inlet of the conveyor device. At least one particulate material may optionally be supplied to the inlet of the conveyor device together with the filter material fibres.
- the present invention provides an apparatus for forming a filter rod from separated filter material fibres for the tobacco processing industry, the apparatus comprising:
- a conveyor device having a conveyor member for conveying separated filter material fibres along a process path in a conveying direction from an inlet to an outlet of the conveyor device, wherein the conveyor member is configured to create a continuous strand of filter material fibres from the separated filter material fibres supplied to the inlet; means for wrapping the continuous strand of filter material fibres in a wrapper material after the strand exits or emerges from an outlet of the conveyor device to form a filter rod having a core of filter material fibres surrounded by the wrapper material; and
- an additive application system comprising at least one applicator device, such as a nozzle, arranged to apply an additive, preferably by spraying, to the strand of filter material fibres in the conveyor device at a position along the process path, and preferably at a position closer to an outlet of the conveyor device than to the inlet thereof.
- the filter material fibres used in the present invention are separated and are thus provided as loose and randomly oriented fibres. Accordingly, it is first necessary to collect and arrange the separated fibres into a generally continuous strand, which is achieved via the conveyor device.
- the apparatus of the invention advantageously provides an additive application system located close to the outlet of the conveyor device. This assists a very efficient delivery of an additive, such as a binder, to the fibres in a controlled and consistent manner without risking an undesired contamination of the conveyor device. Further, the location of the applicator device of the application system at or adjacent to the outlet, e.g. just before the wrapping means, allows application of a binder at the surface of the fibre strand just before wrapping, thereby ensuring quick contact between binder, fibres and wrapper material to provide improved binding action to the fibres and improved stability for the filter rod produced.
- an additive such as a binder
- the conveyor device is a suction conveyor device and the conveyor member is a suction belt.
- the filter material fibres are thus typically supplied to the inlet via a vacuum or under-pressure created by and/or in the suction conveyor device.
- the at least one applicator device such as a nozzle, is desirably arranged in a final one-third, more preferably in a final one-fifth, and even more preferably in a final one-tenth of the process path defined by the conveyor device; i.e. at or upstream of the outlet.
- the conveyor device may typically be expected to have a length in a range of about 1 metre to about 3 metres.
- the at least one applicator device (e.g. nozzle) of the additive application system is arranged proximate to or adjacent the outlet of the conveyor device.
- the applicator device or nozzle may be arranged or oriented at an angle of between 0° and 90° to the conveyor member of the conveyor device.
- the applicator device or nozzle may be directed or arranged to extend substantially parallel to the direction of the conveyor member, preferably within a substantially horizontal plane.
- the additive application system includes at least one second applicator device (e.g. a second nozzle), and the at least one second applicator device may be directed or may extend substantially perpendicular to a travel direction of the continuous strand in the conveyor device.
- the additive application system of the apparatus comprises at least one carrier source and/or a reservoir or a supply of each additive.
- Each carrier source and/or each reservoir or supply is in fluid connection with the at least one applicator device, i.e. preferably with at least one respective nozzle.
- the additive application system preferably includes heating means for heating the additive before or during application thereof in the conveyor device .
- the apparatus includes one or more plate member or baffle member arranged in the conveyor device for locally moderating or reducing a vacuum or under-pressure applied to the strand of filter material fibres at or immediately upstream of the at least one applicator device or nozzle.
- the filter material fibres of the strand on the suction belt can relax allowing the at least one additive to better penetrate the strand, while also reducing additive losses.
- the present invention provides a filter rod which is produced by the apparatus and/or method of the invention as described with respect to any one of the embodiments above.
- the invention thus also provides a smoking article having a filter element cut from such a filter rod.
- Fig. 1 shows a schematic side view of an apparatus for forming a filter rod of randomly oriented fibres for the tobacco processing industry according to one particular embodiment
- Fig. 2 shows a schematic view of the apparatus in Fig. 1 in the direction of arrows B-B;
- Fig. 3 is a flow diagram that schematically illustrates a method according to a preferred embodiment.
- the apparatus 1 in this particular embodiment comprises a suction conveyor device 2 configured to transport or convey separated and randomly oriented filter material fibres F from a fibre supply S at an inlet I of the conveyor device 2 in a conveying direction D along a process path P to an outlet 0 of the conveyor device 2.
- the separated and randomly oriented fibres F are supplied to the inlet I of the conveyor device 2 and may comprise a single type of fibre or alternatively a mixture of different types and optionally also a particulate material.
- the conveyor device 2 For transporting these separated fibres F from the fibre supply S, the conveyor device 2 comprises an elongate conveyor member 3 in the form of an endless suction belt.
- This suction belt member 3 draws the loosely held separated and randomly oriented filter material fibres F from the supply S under the action of an under-pressure or vacuum V and carries those fibres F in the conveying direction D as the suction belt 3 is driven in its endless loop.
- the conveyor device 2 Due to the structure and operation of the suction belt 3, the conveyor device 2 is configured to form or to produce a generally continuous strand 4 of the fibres F as it draws and conveys those fibres F along the process path from the inlet I to the outlet 0.
- the apparatus 1 further includes a wrapping device 5 which interfaces with the conveyor device 2 at the outlet 0 for consolidating the continuous strand 4 of filter material fibres F by wrapping the strand 4 in at least one sheet or web of wrapping material 6, such as one or more thin sheets or webs of paper.
- a wrapping device 5 which interfaces with the conveyor device 2 at the outlet 0 for consolidating the continuous strand 4 of filter material fibres F by wrapping the strand 4 in at least one sheet or web of wrapping material 6, such as one or more thin sheets or webs of paper.
- the apparatus 1 furthermore includes an additive application system 7 having at least one first nozzle 8 configured and arranged for applying an additive A to the strand 4 of filter material fibres F on the process path P in the conveyor device 2.
- Each such first nozzle 8 is arranged at a position proximate or close to the outlet 0 of the suction conveyor device 2 and is desirably arranged to extend or be directed in a plane approximately parallel to the conveying direction D, i.e. a substantially horizontal plane.
- the additive A delivered through the first nozzle 8 is a binder composition projected in a substantially liquid form onto the fibre strand 4 on the suction belt 3 adjacent the outlet 0 of the conveyor device 2.
- the additive A can also be a binder provided in a pulverulent form (e.g. as a powder or micro-encapsulated particles) and projected on the fibres.
- a binder may be activated by subsequently heating and/or by compacting the fibre strand 4 after it exits the conveyor device 2; for example, in the wrapping device 5 or even down ⁇ stream of the wrapping device 5 and before the continuous filter rod R is cut.
- the additive application system 7 includes at least one second nozzle 9 proximate the outlet 0 which extends or is directed approximately perpendicular to the conveying direction D, as shown in Fig. 1.
- This second nozzle 9 can be used to deliver the same additive A as the first nozzle 8 or a different additive, in the same or a different form.
- each of these first and second nozzles 8, 9 is connected via a conduit or piping 10 in fluid communication with a reservoir 11, which holds the additive A to be applied to the fibres F.
- the reservoir 11, and/or the nozzles 8, 9 may include or be associated with heating means for heating the additive A such that it is easily applicable or projectable through those nozzles 8, 9, especially if the additive A is a gel and/or is viscous at room temperature (25°C) .
- the first and second nozzles 8, 9 are desirably also connected in fluid communication to a pressure source 12, e.g.
- each of the first and second nozzles 8, 9 is then preferably connected to a separate reservoir for the respective additive by appropriate conduits or piping, with each reservoir in turn connected to a pressure source.
- the first nozzle 8 may be configured and arranged to spray a binder composition onto the fibre strand 4 at or adjacent an outlet 0 of the conveyor device 2 and thus connected to a binder reservoir.
- the second nozzle 9, may be configured and arranged to introduce an encapsulated additive, such as a breakable capsule, from a capsule supply or reservoir (not shown) into the fibre strand 4 at regular intervals (immediately) prior to the strand exiting the conveyor device 2 to be wrapped via in wrapper device 5 to form the continuous filter rod R.
- the supplies or reservoirs for the binder additive and capsules may then be connected to individual pressure sources to allow application or projection thereof at appropriate pressures of the two additives from each of nozzles 8, 9.
- a vacuum breaker (not shown in the figures) may be provided or arranged in the conveyor device 2 at the position of the first nozzle 8 and/or preferably just before that nozzle.
- a vacuum breaker which may be formed of or comprise a deflection member located upstream of the first nozzle 8 in the process path P, desirably locally reduces the vacuum or under-pressure in the conveyor device 2, thereby relaxing the fibres onto the suction belt 3. This allows for a better penetration of the additive A sprayed onto the fibre strand 4 into the fibres thereof and, thus, a more homogenous blend of the fibres and additive. In addition, this further reduces a risk of contamination in the conveyor device 2 and provides enhanced control of the delivery of the additive A to the fibre strand 4.
- the fibres F in the substantially continuous strand 4 exit or emerge from the outlet 0 of the conveying device 2, they directly enter the wrapping device 5.
- the strip or web 6 of wrapping material e.g. paper
- the wrapping device 5 then consolidates the fibre strand 4 by means of the wrapping material 6 into a substantially continuous filter rod R.
- an applicator 15 may provide the strip or web 6 of paper with a localised adhesive so that the wrapping material is adhesively bonded as it is wrapped around the strand 4 of fibres F. Because the additive A is applied to the fibre strand 4 immediately or directly upstream of the wrapping device 5, that additive A may also interact with the strip or web of wrapping material to provide a uniform and reliably wrapped filter rod. If the additive A is a binder, that also ensures that the randomly oriented fibres F of the filter material do not ravel or fray when the filter rod R is later cut to form individual filter segments for smoking articles.
- a flow diagram is shown that schematically illustrates the steps in a method of forming a filter rod R of filter material fibres F according to the embodiment of the invention described above with respect to Figs. 1 and 2.
- the first box I of Fig. 3 represents the step of supplying the filter material fibres F to the inlet I of the conveyor device 2, e.g. via a fluidised bed (not shown) .
- the second box II then represents the step of conveying the filter material fibres F along a process path in a conveying direction D from the inlet I to an outlet 0 of the conveyor device 2, whereby a substantially continuous strand 4 of the filter material fibres F is formed along the process path defined by the conveyor device 2.
- the third box III represents the step of introducing at least one additive A, especially a binder, to the strand 4 of filter material fibres F in the conveyor device 2 at a position in the process path P closer to the outlet 0 than the inlet I.
- the final box IV in Fig. 3 of the drawings represents the step of consolidating the filter material fibres F into a filter rod R by wrapping the fibre strand 4 with a wrapper material 6 after the strand 4 exits the outlet 0 of the conveyor device 2 in the conveying direction D.
