Opfindelsen vedrører et tobaksrøgfilter bestående af en aksialt langagtig filterkerne og et om kernen fastgjort omslag af et røguigennemtrængeligt materiale.The invention relates to a tobacco smoke filter consisting of an axially elongated filter core and a wrapper fixed to the core of a smoke-impermeable material.
5 En foretrukket udførelsesform af tobaksrøgfilte ret ifølge opfindelsen er ejendommelig ved, at det røguigennemtrængelige materiale udgøres af et laminat af papir, syntetisk termoplast og papir.A preferred embodiment of tobacco smoke felt according to the invention is characterized in that the smoke impermeable material is constituted by a laminate of paper, synthetic thermoplastic and paper.
Det syntetiske termoplastmateriale i laminatet 10 kan være et polyolefin, fortrinsvis polyethylen.The synthetic thermoplastic material in laminate 10 may be a polyolefin, preferably polyethylene.
Filteromslagsmaterialet, der anvendes ifølge opfindelsen, har en særlig fordelagtig kombination af ønskelige egenskaber, idet det let anbringes i stilling ved hjælp af en overlappende og limet søm; det 15 er ifølge sagens natur meget uigennemtrængeligt for luft og røg, og det har gode permanente prægningsegenskaber med opretholdelse af uigennemtrængeligheden.The filter cover material used in accordance with the invention has a particularly advantageous combination of desirable properties, being readily placed in position by an overlapping and glued seam; It is, by its very nature, highly impervious to air and smoke, and it has good permanent imprinting properties while maintaining impermeability.
Kendte filteromslagsmaterialer har højst udvist to af disse egenskaber. Filteromslaget, der anvendes 20 ifølge opfindelsen, er særlig fordelagtigt til brug ved produktionen af filterstrenge med langsgående periferipassager; filteromslaget kan forpræges til den ønskede udformning, dvs. med langsgående riller eller korrugeringer, der kan være kontinuerlige eller 25 adskilt af områder (dvs. områder, der ikke er prægede, eller som er prægede med laterale korrugeringer), hvor de langsgående riller eller korrugeringer ender, og derefter kan de være viklet omkring en aksialt langagtig filterkerne og fastgøres ved hjælp af en 30 overlappende og limet søm. Det prægede filteromslag tilvejebringer således de krævede ydre, uigennemtrængelige riller. I nogle tilfælde, f.eks. når det prægede filteromslag påføres en filterkerne af plasti-ficeret celluloseacetatfilamenter eller -fibre, når 35 sidstnævnte ikke er fuldt hærdede, kan det prægede filteromslags profil trykkes ind i filterkernen, så at de to svarer fuldstændig til hinanden. I andre tilfæl-Known filter cover materials have exhibited at most two of these properties. The filter cover used in accordance with the invention is particularly advantageous for use in the production of filter strands with longitudinal peripheral passages; the filter cover can be pre-embossed to the desired design, i.e. with longitudinal grooves or corrugations which may be continuous or separated by regions (i.e., areas which are not embossed or which are embossed with lateral corrugations) where the longitudinal grooves or corrugations end, and then they may be wound around a axially elongated filter core and secured by an overlapping and glued seam. The embossed filter cover thus provides the required outer, impervious grooves. In some cases, e.g. when the embossed filter cover is applied to a filter core of plasticized cellulose acetate filaments or fibers, when the latter is not fully cured, the profile of the embossed filter cover can be pressed into the filter core so that the two correspond completely to each other. In other cases-

2 de, når kernen på tidspunktet for omviklingen er hårdere, kan der forekomme ringe eller ingen omformning af kerneperiferien til omslagsprofilet, så at de indre kanaler vil være afgrænset mellem kernen og omslaget.2, when the core is harder at the time of wrapping, there may be little or no reshaping of the core periphery to the cover profile, so that the inner channels will be bounded between the core and the cover.
5 Andre prægede udformninger af filteromslagslaminatet er mulig. F.eks. kan det være præget med langsgående overlappende riller med begrænset længde og placeret med indbyrdes afstand langs periferien, eller rillerne eller korrugeringerne kan være erstattet af områder 10 med fordybninger, til tilvejebringelse af et mønster af indbyrdes forbundne passager eller kanaler på ydersiden af den omsluttede kerne.Other embossed designs of the filter cover laminate are possible. Eg. it may be embossed with longitudinal overlapping grooves of limited length and spaced apart along the periphery, or the grooves or corrugations may be replaced by areas 10 with recesses to provide a pattern of interconnected passages or channels on the outside of the enclosed core.
De forskellige prægningsudformninger af filteromslagslaminatet opnås let ved at føre det ubehandlede 15 filteromslag mellem opvarmede, samvirkende prægningsruller af den ønskede overfladeudformning, idet for-varmning af det ubehandlede filteromslag til blød-gøring af det termoplastiske lag undertiden kan være fordelagtig.The various embossing designs of the filter cover laminate are readily obtained by passing the untreated filter cover between heated, cooperating embossing rolls of the desired surface design, preheating the untreated filter cover to soften the thermoplastic layer can sometimes be advantageous.
20 Filterstrenge, hvor prægede laminatfilterom slag ifølge opfindelsen anvendes, kan være forsynet med et ydre omslag i anlæg omkring det prægede filteromslag, dette ydre omslag kan påføres kontinuerligt, som en del af filterproduktionsprocessen, umid-25 delbart efter påføringen af det prægede laminatfilter-omslag, eller det kan være et mundstykkeomslag, der anvendes til at fastgøre det enkelte filterelement til en tobakstreng ved produktionen af en filtercigaret; i hvert tilfælde kan det ydre omslag være et 30 luftgennemtrængeligt materiale og/eller være perforeret til tilvejebringelse af passage for yderluft gennem det ydre omslag ind i ydre riller eller passager, der tilvejebringes af det prægede filteromslag.Filter strands using embossed laminate filter casings according to the invention may be provided with an outer wrap in abutment around the embossed filter wrap, this outer wrap may be applied continuously, as part of the filter production process, immediately after application of the embossed laminate filter wrap or it may be a mouthpiece cover used to attach the individual filter element to a tobacco string in the production of a filter cigarette; in each case, the outer cover may be an air-permeable material and / or be perforated to provide passage for outside air through the outer cover into outer grooves or passages provided by the embossed filter cover.

Det laminerede filteromslag kan imidlertid også anvendes i sin ubehandlede, uprægede tilstand, og hvad enten det er ubehandlet eller præget kan det til særlige formål og filterkonstruktioner være for-5 synet med perforeringer, enten jævnt fordelt eller i begrænsede områder. Hvad enten det laminerede filteromslag er perforeret eller ikke perforeret, ubearbejdet eller præget, kan filterkernen, hvorom omslaget er viklet, være fremstillet af mange forskellige ma-10 terialer og i mange forskellige udformninger. Filteret kan selv være et viklet legeme eller ikke-viklet, filtermaterialet i kernen kan bestå af bundne eller ikke-bundne filamenter eller stabelfibre, f.eks. af celluloseacetat, creppet papir etc.; kernen kan om-15 fatte en kombination af sammenstødende propper med indbyrdes afstand i længderetningen af samme eller forskellige materialer; kernen kan omfatte partikelformede additiver, der er jævnt fordelt i denne, eller som er placeret i lommer med indbyrdes afstand eller 20 mellemrum i kernen; kernen kan have en profileret (dvs. i længderetningen rillet) periferi, og den kan have indre passager eller hulrum, som kan være fyldt eller ikke fyldt. Det laminære filteromslag kan omgive et hulrum eller recesser, der er åbne ved 25 den ene ende af filteret, og i en filtercigaret kan en sådan reces eller hulrum ligge an mod tobakstrengen eller vende mod mundingsenden.However, the laminated filter cover can also be used in its untreated, unstressed condition, and whether untreated or embossed, it may be provided with perforations, either evenly distributed or in restricted areas, for special purposes and filter designs. Whether the laminated filter cover is perforated or not perforated, unworked or embossed, the filter core around which the cover is wrapped can be made of many different materials and in many different designs. The filter itself may be a wound body or non-wound, the filter material in the core may consist of bonded or non-bonded filaments or staple fibers, e.g. of cellulose acetate, scraped paper, etc .; the core may comprise a combination of longitudinal spaced butt plugs of the same or different materials; the core may comprise particulate additives evenly distributed therein, or located in spaced apart pockets or spaces in the core; the core may have a profiled (i.e., longitudinally grooved) periphery, and it may have internal passages or voids which may be filled or not filled. The laminar filter cover may surround a cavity or recesses open at one end of the filter, and in a filter cigarette such recess or cavity may abut the tobacco strand or face the mouth end.
En type af laminat, der er egnet til brug ifølge opfindelsen, udformes ved ekstrudering af en 30 bane af det syntetiske termoplastmateriale og påføres baner af papir på hver side af ekstruderingen og klæber disse sammen, medens det syntetiske termoplastmateriale stadig er klæbrigt. Et passende laminat fremstillet på denne måde har et midterlag af 35 polyethylen, der vejer 10 g/m2, med derimod liggende 4One type of laminate suitable for use in the invention is formed by extruding a web of the synthetic thermoplastic material and applying webs of paper to each side of the extrusion and adhering them while the synthetic thermoplastic material is still sticky. A suitable laminate prepared in this way has a middle layer of 35 polyethylene weighing 10 g / m2, with opposite 4

lag af maskinglittet papir, der hver har en vægt på 25 g/m2. En anden type af laminat, der er egnet til brug ved opfindelsen, har det syntetiske termopla-stiske lag bundet med klæbemiddel til de anliggende 5 papirlag, et sådant laminat har igen et 10 g/m2 polyethylenlag med creppet papir bundet ved klæbemiddel på hver side, idet et af papirlagene har en vægt på 25 g/m2 og det andet et vægt på 35 g/m2. Medens det laminat, der anvendes ifølge opfindelsen, sædvan-10 ligvis består af et enkelt syntetisk termoplastlag med et enkelt papirlag på hver side, kan laminatet også omfatte yderligere lag mellem de mod hinanden vendende papirlag.layers of machine-scraped paper, each weighing 25 g / m2. Another type of laminate suitable for use in the invention has the synthetic thermoplastic layer bonded with adhesive to the abutting paper layers, such a laminate again having a 10 g / m2 creped polyethylene layer bonded to each side , one of the layers of paper having a weight of 25 g / m2 and the other a weight of 35 g / m2. While the laminate used according to the invention usually consists of a single synthetic thermoplastic layer with a single paper layer on each side, the laminate may also comprise additional layers between the facing paper layers.
