Referring to Figure 1, the cork 0) comprises a bar (rolled) in eralmente cylindrical of material that can be like tobacco, which is coaxially attached to 0) by the paper with filter (300) stuck to the end of the bar (110) and the filter (200). The 0) comprises a generally cylindrical filter tow.

The cylindrical tow of material catches one or more sections, each of which is a composition of different materials.

CO.

A general example of a 4) element for forming a filter (200) according to the invention is described below with references 2 to 4. Referring to FIG. 2, the filter material (210) on the filter element is shown in FIG. first and second gene end faces (211), (212) and a surface that is longitudinally (213) or circumferentially perpendicular to the first and end ends (211), (212).

The plug of filter material 210 of filter 214 is wrapped by a sheet waste in the form of a plug wrap 220. As shown in the plug wrap 220, it is wrapped alred ?? (220) could directly adhere the surface (213) of the filter material (210 mplo by applying a plurality of adhesive (230) to the inner surface (2 cap oligo (220).) The application of tive ( 230) to the plug wrap (230) was moved Figure 11.

The plug wrap (220) can be conventional paper materials. Without a plug tamper (220) it may, alternatively, comprise tobacco or onstitute material. The cap wrapper (220) also consists entirely of onstitute material, such as a sheet of reconstituted paper. The tobacco material reconstituted a different color to the plug of material of O) and the inner surface (221) of its wrapper (220). The tobacco product (240) can be in the form of cut tobacco. Typically, the tobacco product (240) forms cut tobacco. Alternatively, tobacco (240) may comprise reconstituted strips or particles or paper containing tobacco, any combination of the above.

The tobacco product (240) can be to the internal surface (221) of the wrapper d 0) by using a suitable adhesive, such as a tobacco pipe (240) covering all or a longitudinally extending surface of the filter material plug. (210) when the cap wrapper (220). When the wrapper (220) is wrapped around the plug in this example of the invention, the filter comprises a first filter element (214) that c tobacco product (240) as above, and a second filter element ( 2 contains a tobacco product The shape of the second filter element (21 corresponding to those of the first element of 4), with the tobacco product (240) omitted, as described below, in this invention, The first filter element is an adsorbent such as activated carbon.

The first and second filter elements 5) are generally cylindrical, the discrete elements (214), (215) of substantial diameter. In this example, the filter material of the second filter element (215) is computationally, the activated carbon may be a sticky outer surface (213) of the cellulose tablet (210), or it may adhere to surrounded cotton by the acetate plug of c O). The activated carbon could also maintain a cavity surrounded by the c-O acetate plug.

Although in Figures 5 and 6 the first and filter mentions (214), (215) are Stancially equal in length, elements (214), (215) could alternatively be different lengths. In addition, it will be appreciated tro (200) may comprise more than two elements. For example, the filter (200) can be combined with second filter elements composed of cellulose and a third filter element. As shown in FIGS. 5 and filter elements (214), (215) it is gitudinally relative to each other with the end face 2) of each filter element (214), (215) contiguous. Referring to Figure 8, the elements (214), (215) are wrapped by an upper part (250), which can be maintained around the filter elements (214), (21) along a length of fold of erpuesto of a similar form to the wrapper d 0). The outer casing (250) can complete the filter (200).

Returning to Figure 1, the filter (at one end for the mouth of the article (100) so that a gas flow ignites the smoke coming from the bar (gaseous as it moves through the filter thus It is capable of affecting the chaotic gas flow before the flow reaches smoked.

The tobacco product (240) can, by virtue of the general properties of the gas flow form the flavor and aroma of the gas flow, making the gaseous flow more attractive. An application of the tobacco product (to a certain degree, the characteristics of the gas flow that can be lost as the gas flow moves through the O material). In this sense, the coverage of the product (240) can be confined to the surface longitudinally (213) of a filter section (210), either in the filter (20) to provide a substantial coverage on the surface ( 213) of the material of O) in the filter (200). Alternatively, differs from the surface (213) of the material of O), either especially the filter (200) or filter element (214), (215), can be covered by loads of the tobacco product (240 mplo, the tobacco product (240) can be portioned into a plurality of strips, as will be more detailed below.

Referring to Figs. 10 and 11, tive (230) may be applied to the surface 1) of a plug wrap sheet (220). The adhesive (230) can provide a measurement of the tobacco product (240) to the supra (221) of the plug wrap (220), aco (240) to the plug wrap (220) is tobacco product (240). ) with the adhesive (230) applied to the cap wrapper (220). I referred Figure 11, can comprise passing a stopper cap sheet (220) through a catheter (400) in the direction of the arrow A, in applicator nozzles (500) apply the thread (230) in parallel, longitudinally to the internal surface (221) of the wrapper d 0). The adhesive (230) for the strips can be routed through the nozzles (500) from 0). If the tobacco product (240) is mixed (230) as described above (500), it may also be responsible for the production of the tobacco product (240) to the top (221) of the plug wrap (220). Ón (220) by any other method of api cuado. For example, the adhesive (230) lies on the inner surface of the wrapper (220).

Referring to FIG. 12, for filter element (214), a flat wrapping sheet (220) and a generally suitable cylindrical filter tow can be fed with wrapper (700) in the direction of the Here, the The plug wrap (220) is around the tow of filter material and peg stick nozzle (800) so that the wrapper (220) completely covers the sub-frame (213) of the filter material. The material and the circumferential plug wrap can be cut into even lengths
