Description of the Invention: [Technical Field] The present invention relates to a tobacco smoke filter having a non-circular cross-section of a tobacco smoke filter, an outer layer of a gas permeable material surrounding the core, and optionally a wrap around the outer layer Packed outside. [Prior Art] A concentric core cigarette filter is well known which comprises a cylindrical core inside a filter material surrounded by an outer layer (annular or annular layer) of another filter material. The use of two such different filter media for the core layer and the outer ring layer can result in an unsightly end appearance of the finished cigarette filter product, and thus, in addition to a common oral end plug that can accept a uniform appearance, conventionally, a concentric core Filters are used for dual or other multi-component filters. The present invention relates to a "concentric" core filter wherein the inner core has a defined non-circular cross section. This provides a significant, more attractive end appearance to the filter, eliminating the need to combine concentric core filters with conventional oral end plugs, thereby reducing the number of steps in cost and overall filter manufacturing operations. It should also be noted that the remarkable appearance is provided to the finished cigarette filter for the purpose of anti-counterfeiting. To provide these advantages, an inner core (outer layer) must be formed to define a good shape in a subsequent process step to be maintained in a subsequent process step (packaging, tobacco rod connection, encapsulation of the resulting cigarette, etc.). SUMMARY OF THE INVENTION In accordance with the present invention, a method of making a tobacco smoke filter or filter element is provided, comprising: continuously advancing a longitudinally extending (inner) core of a non-circular cross-section of a tobacco smoke filter material to form a longitudinally extending outer layer ( For example, a roughly annular outer layer). 201200043 Longitudinally extending outer layer < by extending the longitudinal extension (inner) continuously through the hollow tube, and continuously extending longitudinally around the circular cross section (inner W formation; edge (eg, along and around) The outer surface of the hollow tube continuously advances the tobacco smoke filtering stream; and when the anger leaves the hollow tube, the core is continuously advanced (internal), condensed (eg, by means of extraction and collection) Preferably, the tobacco forming the outer layer is a cellulose acetate tow 'which optionally includes a plasticizer (such as triacetin). The method may include, in a non-circular cross section Further heat treatment of the grass smoke filter, the advancing outer layer of the material, optionally with a subsequent cooling step, is carried out continuously as in the longitudinally extending (inner) core formation (e.g., coagulation) and/or shortly thereafter. (and optional cooling) activates the plasticizer, forming a continuous filter around the formed anger's, bonding the 'smoke permeable structure. The continuous advancement of the non-circular cross-section of the tobacco smoke filter The extension (inner) core may be formed shortly before or substantially shortly before forming the longitudinally extending outer layer of the tobacco smoke filter material around the core, for example as part of the same continuous straight line procedure. The non-circular cross section of the final grass smoke material continuously advances The longitudinally extending (inner) core may be formed by continuously advancing (e.g., continuously extracting and/or collecting) the tobacco smoke filter material through a mold having a non-circular cross section. Preferably, the filter material forming the longitudinally extending (inner) core is acetate. a silk tow, optionally comprising a plasticizer (such as triacetin). The method may comprise a further step 'when advancing the longitudinally extending (inner) core is formed and/or shortly thereafter [eg by continuously advancing) (eg continuous extraction and/or collection) of the tobacco smoke filter material flowing through a non-circular cross-section forming mold and/or shortly thereafter], heat-treated advanced longitudinally extending (inner) core, optionally with subsequent cooling - 4 - 201200043 The heat treatment (and optional cooling) activates the plasticizer to form the filter material into a coherent, bonded, smoke-permeable longitudinal extension (inside) Core. The above defined manufacturing method overcomes the problem of forming a shaped core and maintaining a well-defined core shape because the preformed core is in the second step (as in the second fitting) in the second step (as in the second fitting) Extracted and combined with external materials. This method provides a filter and filter element with a significant and attractive end appearance, eliminating the general necessity of concentric round core filters in combination with conventional oral plug plugs, and The cost and overall number of steps in the filter manufacturing operation are reduced. The significant appearance provided to the final filter cigarette product can be advantageously used for anti-counterfeiting. Thus, in accordance with the present invention, a tobacco smoke filter or filter element is provided (by The method of the present invention comprises: a longitudinally extending inner core of a tobacco smoke filter; and a longitudinally extending outer layer of tobacco smoke filter material extending longitudinally about the inner core; wherein the longitudinally extending inner core is a non-circular cross section. Preferably, the longitudinally extending outer layer of the tobacco smoke filter material is wrapped around (e.g., surrounding) the longitudinally extending inner core, the outer surface of the inner core being surrounded by a longitudinally extending outer layer of the tobacco smoke filter material. The filter or filter element is generally circular or elliptical in cross section. The longitudinally extending inner core can be star-shaped, trilobal, pentagonal, gear-shaped, heart-shaped or truncated, or other non-circular cross-section. Preferably, the longitudinally extending core of the non-circular cross section of the tobacco smoke filter material does not have a helical cross section. The inner core and/or outer core may comprise a cellulose acetate tow, optionally comprising a plasticizer. The inner core and/or outer core may include a color element. The inner anger is preferably a contrasting color relative to the outer layer. The grass smoke filter .201200043 or the filter element may comprise an extension package around the tobacco smoke nozzle or filter element. The outer layer is preferably attached to the core material to resist separation. The choice of the inner and outer layers of the final cigarette tip (around the generally annular body) and the venting (if any) cause the flow of smoke to pass primarily through the mouth of a filter or nozzle assembly (for example, the outer layer), for example, Take advantage of the filtering features provided by a particular knockout assembly. This can be achieved by selecting the appropriate level of pressure drop, with the level of retention provided by the inner core and outer layer, plus the level of ventilation of the finished cigarette product, guiding the smoke flow path through the inner core or outer layer. The present invention can thereby provide enhanced filtering features in combination with the parallax features provided by the end appearance. For example, when used in a ventilated cigarette, the filter can significantly reduce the presence of one of the carbon oxides and gas phase compounds in the mist without reducing the tar-Rida amount by the same amount as conventional ventilated cigarettes. This makes it possible to hold the taste of the cigarette and the acceptable pressure &amp; especially in ultra low tar rolls while reducing the fumes of carbon monoxide and other volatile compounds. Preferably, the inner core and the outer layer (generally surrounding the annular body) are collected and bonded cellulose acetate tows. Other fibrous or filamentous materials can also be used in any core or outer layer. Preferably, the (inner) core (including the pigment and the pigment) is a different color to highlight the appearance of the end of the mouth. For example, the shaped core can be beta blue, green or black in color and the outer layer can be white. When the color (pigment) material is used in the inner core, select the filter or filter ventilation unit (AL me armor) to conduct the smoke mainly along the core, and advantageously obtain the cigarette after the second & impression. Alternatively, if a white core and a white outer layer are used, it is possible to make the core shape more pronounced during the smoking period due to the rapid passage of the smoke along the core. This feature can be used as a security feature and/or to enhance brand recognition. 201200043 In accordance with yet another aspect of the present invention, a method of making a tobacco smoke filter or filter element is provided, comprising: aligning two or more longitudinally extending portions of a tobacco smoke filter material having a uniform cross-section side by side to form The step of unifying the longitudinal extension of the tobacco cross-section of the solid section. As used herein, "solid cross section" means that the cylindrical core has a circular (or elliptical) cross section (formed by the longitudinal extension of the tobacco smoke filter material) without the (longitudinal extension) gap or void between such portions. In other words, a cylindrical core of a tobacco smoke filter having a uniform solid cross section exhibits a full circle or ellipse (without gaps) at its ends. The "solid cross section" is breathable. Thus, in accordance with yet another aspect of the present invention, there is provided a tobacco smoke filter or filter element (for example formed by the method according to the invention) comprising a plurality of longitudinally extending portions of a tobacco smoke filter material having a uniform cross section; A plurality of longitudinally extending portions are aligned side by side to form a longitudinally extending cylindrical core of tobacco smoke filter material having a uniform solid cross section. The tobacco smoke filter or filter element can include two longitudinally extending portions of the tobacco smoke filter material having a uniform cross section; the longitudinally extending portions are aligned side by side to form a longitudinally extending cylindrical core of the tobacco smoke filter material having a uniform solid cross section. The boundary between adjacent longitudinally extending portions aligned side by side may have an elongated s shape in cross section. The two or more longitudinally extending portions of the filter media can be contrasting colors. The tobacco smoke filter or filter element can further comprise an extended package configured around the filter or filter element. In this aspect of the invention, two (or more) filter media are aligned side by side rather than coaxially. The two side-by-side components can use different colors, and the boundary between the two tow components can be in a defined shape, such as an elongated "s", so that the end of the filter or filter element is 5 201200043 Now looks like the round face of the yin and yang symbol (see Figure 3). The filter or filter element according to any aspect of the invention is preferably wrapped in an outer plug package. This plug package can be porous or non-porous. The filter according to the present invention is preferably formed to a continuous length and then cut to a finite length. This may be a multiple of the length of the final filter product (eg, four or six times). The filter can be between 14 and 28 mm in circumference and between 15 and 40 mm in length. The tobacco smoke filter or filter element according to the invention may have a circumference of from 14 to 28 mm, such as from 16 to 26 mm, such as from 16 to 17 mm or from 24 to 25 mm. The tobacco smoke filter of the present invention may have a length of 10 to 40 mm, for example, 15 to 35 mm, for example, 20 to 30 mm. The tobacco smoke filter element of the present invention may have a length of 5 to 30 mm, for example: 6 to 20 mm, for example, 8 to 15 mm, for example 10 to 12 mm. The filter and filter elements according to the present invention can be used in machine building cigarettes (such as those produced and packaged). The filter and filter elements according to the present invention can also be used as (or for) a filter for individual roll-to-roll (e.g., hand-rolled cigarettes) or self-rolling (Roll Your Own) or self-service products. The filter element according to the invention can also be used as a multi-stage filter, for example a double, triple, etc. mouth end section of a multi-filter. Such filters are well known in the art. The invention includes any filter cigarette made using the filter according to the invention. [Embodiment] [Detailed Description of the Invention] The present invention will now be described with reference to the accompanying drawings.

Again, by means of methods well known in the art (not shown in Figure 4), • bundles are continuously extracted from one or more packets, The filaments were formed into a thin expanded layer by longitudinally pressing each of the filament strands to separate the filaments, and the tow was sprayed with -9- & 201200043 glycerol triacetate. Once processed, the second stream is applied around the inner core as shown below. The continuous advancement core of the tobacco smoke filter of the desired section (1 1 a) is pushed into and pushed through the hollow tube (丨5) in the outer casing (16). With a further fitting and endless belt, the longitudinally advanced second filament stream (2 turns) is passed around the hollow tube to advance in the same direction as the inner core (in the direction of arrow 23). The second tow stream (21) is condensed around the forming core as the core advances and exits the hollow tube, thereby forming a substantially annular outer layer (1U) in the outer casing around the inner core (11a). The inner core is centered in the finished filter product. The steam passes through the endless belt and contacts the envelope filament of the second tow stream, and the cargo is carried during its passage through the outer casing to activate the triacetin bonding contained thereon. The composition then forms a coherent, bonded, smoke-permeable (outer) layer around the forming core. The continuous outer layer is formed by the condensation of the outer layer by the longitudinal extension of the non-circular cross-section. The rod (31) is advantageously formed shortly after cooling. The package is arranged in a conventional manner, i.e. by means of an ordinary packaging accessory arranged upstream of the tool. Thus, the program provides a filter rod (3 1 ) comprising tobacco The longitudinally extending inner core (1 1 a) of the smoke filter material and the longitudinally extending outer layer of the tobacco smoke filter material (2丨^, which extends in a longitudinally extending inner anger; wherein the longitudinally extending inner core has a non-circular cross section.梓 can use this technology A method known in the art for cutting into the length of a single or multiple "mouth" or multi-stage filter elements for subsequent use (ie as a filter or filter element, or for combining other filter or filter elements). The filament material for the longitudinally extending core component is fed into the cookware and fitting arrangement to form the desired (non-circular) shape, and the core thus formed is subsequently passed over the filament of the outer layer as it passes through the further fitting The material is surrounded by -10-201200043 and is wrapped around to provide - a shaped core and a filter rod that maintains the boundary. The above manufacturing method overcomes the problem of the shape of the wrath and the anger of the rape, because the core is angry Figure 1 shows a station bonded by a ring material of a second fitting. One end (or element or 捍U method) is made into the inner core of the filter tow according to the present invention, and has a side filter comprising plasticized cellulose acetate. The cross section of the filament in the plug wrapper (3) V of the angle star (1), which is closely surrounded by the outer layer. 幵: the outer layer of the white acetic acid f-dimensional filament tow (2) is contrasted Green 1 core cellulose acetate tow including and white It should be noted that the star 榲 素 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , The plasticized cellulose acetate of the present invention is long. The filter comprises a heart-shaped red (pigment), a ring-shaped plasticized white, and an east core, which is wrapped around the plug wrapper (3). Using a heart-shaped phthalic acid filament tow (2) between the tightly surrounding and white surrounding layers to form a core, and the red heart-shaped core in the embodiment - "provides significant End-face appearance. Filter element, which can be similarly manufactured by using a similar method to make a filter or a face-to-face tobacco smoke crossing 4 $ (rather than fortunately arranged) and each has a uniform and through-accessory Two or more longitudinal extensions are taken and collected to form a longitudinally extending cylindrical core of tobacco smoke filter having a uniform solid cross section. The two side-by-side sections can be of different colors and the tows are formed. The boundary between the 卩 points can be in a well-defined shape, such as an elongated "S" or a formatted yin and yang symbol. Figure 3 shows one end (or 70 pieces or rods) of another filter according to the invention made by the method of the above. Two different colors of acetic acid -11 - 201200043 The plasticized filament tow of the cellulose tow is arranged side by side. The filter consists of a green filter (1 b) and a black filter (2 b ), forming two distinct areas with an "S" shaped curve at the boundary. The filter is housed in a plug wrap (3b). Contrast green and black to provide a significant end look.
