2 146814 I 1960’erne interesserede man sig navnlig for dannelse af multifiltre, der indeholdt løst granuleret materiale. Der opstod imidlertid herved mange forskellige problemer, både ved udvikling af praktisk anvendelige processer og apparater til fremstilling af filtrene, og ved tilvejebringelse af et filter, der vil opfylde det tilstræbte formål på en måde, der er tiltalende og acceptabel for forbrugerne.2 146814 In the 1960s, interest was mainly given to the formation of multifilters containing loose granular material. However, many problems arose here, both in the development of practical applications and apparatus for making the filters, and in providing a filter that would fulfill the intended purpose in a manner that is appealing and acceptable to the consumer.
I beskrivelsen til talrige U.S.A. patenter, herunder nr. 3.259.029, Hall et al., nr. 3.312.151. Molins, nr. 3.343.462, Sexstone, nr. 2.464.323, Pinkham, nr. 3.482.488, Sexstone, nr. 3.610.112,In the description to numerous U.S.A. patents, including No. 3,259,029, Hall et al., No. 3,312,151. Molins, No. 3,343,462, Sexstone, No. 2,464,323, Pinkham, No. 3,482,488, Sexstone, No. 3,610,112,
Labbe, samt nr. 3.623.404, Jackson, der omhandler fremgangsmåder og apparater til fremstilling af filterpropper med afsnit, der består af partikelformigt materiale. Herfra kendes anvendelsen af en proces, ved hvilken adskilte cylindriske propper af et første materiale dannes på et kontinuert omslag, hvorefter partikelformigt materiale anbringes på omslaget mellem de adskilte propper, hvorefter omslaget lukkes omkring propperne og materialet til dannelse af en filterstav.Lab, and No. 3,623,404, Jackson, which discloses methods and apparatus for making filter plugs having sections consisting of particulate material. From this it is known the use of a process in which separated cylindrical plugs of a first material are formed on a continuous cover, after which particulate material is applied to the cover between the separated plugs, after which the cover is closed around the plugs and the material to form a filter rod.
Disse metoder har været mere eller mindre tilfredsstillende. Der har været problemer som følge af vanskeligheder med fuldstændig udfyldning af filterstavens partikelformige afsnit. Såfremt en vej med mindste modstand, bevæger sig mellem det partikelformige materiale og omslaget og derved i det mindste delvis unddrage sig den tilsigtede virkning, nemlig at røgen skal passere imellem de enkelte partikler.These methods have been more or less satisfactory. There have been problems due to difficulties in completely filling the particulate section of the filter rod. If a path of least resistance moves between the particulate material and the cover, thereby at least partially avoiding the intended effect, namely that the smoke must pass between the individual particles.
Der har også været vanskeligheder med denne teknik i forbindelse med processer til fremstilling af cigaretter med høj hastighed.There have also been difficulties with this technique in the process of producing high speed cigarettes.
Der er således problemer ved at levere den nøjagtige mængde af partikelformigt materiale, der kræves til tilvejebringelse af den tilstræbte filtrering.Thus, there are problems in supplying the exact amount of particulate material required to provide the desired filtration.
Endelig skal det bemærkes, at det er vanskeligt at holde styr på det partikelformige materiale, idet dette vil kunne trænge ind i dele af filtreret og cigaretternes tobaksindhold, hvor dets tilstedeværelse er uønsket og ubehagelig for rygeren.Finally, it should be noted that it is difficult to keep track of the particulate matter as this may penetrate into portions of the filtered and cigarette contents, where its presence is undesirable and unpleasant to the smoker.
I modsætning til de ovenfor nævnte processer omhandler beskrivelsen til U.S.A. patent nr. 3.371.000, Davenport et al forskellige me- 3 1468 Η toder til anbringelse af striber af partikelformigt materiale på et baneformet underlag, der derefter samles til en filterprop.In contrast to the processes mentioned above, the description relates to U.S.A. Patent No. 3,371,000, Davenport et al., various methods for applying strips of particulate material to a web-shaped substrate which are then assembled into a filter plug.
Ved en udførelsesform trykkes striber af slam, der indeholder partikelformigt materiale, på celluloseacetat, papir eller andet materiale, der anvendes til dannelse af filterstave. Ved andre udførelsesformer indsprøjtes slam med en nåledyse på adskilte steder i en tildannet prop.In one embodiment, strips of mud containing particulate material are printed on cellulose acetate, paper or other material used to form filter rods. In other embodiments, sludge is injected with a needle nozzle at separate locations into a formed plug.
Dette patentskrift viser i fig. 15 og 16 en anden udførelsesform, ved hvilken der anvendes et roterende hjul med udsparinger langs yderkransen til overføring af granuleret materiale fra en tragt til adskilte steder på en bane af filterdannende materiale, idet denne bane bliver bragt i berøring med yderkransen af hjulet og løber sammen med dette langs en fastlagt bue, hvorved det granulerede materiale ved tyngdekraften overføres til banen.This patent illustrates in FIG. 15 and 16, another embodiment utilizes a rotating wheel with recesses along the outer rim to transfer granulated material from a hopper to separate locations on a web of filter forming material, this web being brought into contact with the outer rim of the wheel and running together with this along a fixed arc, whereby the granular material is gravitationally transferred to the web.
Ved visse af de beskrevne udførelsesformer har det vist sig, at den på banen afsatte materiale "vil kunne blive ført bort ved zoner med berøring med dele af propdanneren, inden den samlede stav bliver omhyllet" (spalte 13, 1. 58-60). For at undgå sådan berøring "bliver en bane af porøst papir, ikke-vævet stof eller lignende påført oversiden af banen, strengen eller garnet og bevæger sig sammen med dette og bliver indesluttet i den samlede stav af bane, streng eller garn" (spalte 13, 1. 73 til spalte 14, 1. 2). På denne måde beskyttes det granulerede materiale, når det indføres i garnituren, for at forhindre, at det fjernes fra banen.In some of the embodiments described, it has been found that the material deposited on the web "may be carried away by zones of contact with parts of the plug former before the entire rod is wrapped" (column 13, 1. 58-60). To avoid such contact, "a web of porous paper, non-woven fabric or the like is applied to the top of the web, string, or yarn, and moves therewith and is enclosed in the overall web of web, strand, or yarn" (column 13 , 1. 73 to column 14, 1. 2). In this way, the granulated material, when introduced into the garnish, is protected to prevent it from being removed from the web.
Denne anden bane tilføres imidlertid fra en særskilt rulle uden at blive udbredt eller spændt. Selv om denne anden bane blev udbredt og spændt, ville det være praktisk uigennemførligt at forsøge at opnå ensartet spænding og udbredning af de to baner som følge af variationer i udstyret og i selve banematerialet. Ved sådanne variationer frembringes der filtre af dårlig kvalitet. Sådanne filtre har tilbøjelighed til at krumme sig eller vrides. Endvidere er det umuligt at opnå ensartet trykfald gennem filtret, hvilket medfører uacceptable variationer mellem cigaretter af det samme mærke.However, this second web is fed from a separate roll without being widespread or tense. Although this second web became widespread and tense, it would be practically impracticable to attempt to achieve uniform tension and propagation of the two webs due to variations in the equipment and in the web material itself. Such variations result in poor quality filters. Such filters tend to curl or twist. Furthermore, it is impossible to achieve uniform pressure drop through the filter, causing unacceptable variations between cigarettes of the same brand.
Man erkendte også, at dannelse af sådanne striber af granuleret materiale er kompliceret som følge af, at der kan forekomme varie- 4 146814 rende strækning af banen, eftersom dennes materiale vil blive forlænget under trækspænding (spalte 6, 1 - 2), hvorved striberne bliver deformeret. Patentskriftet foreslår forskellige måder til nedsættelse af dette problem, men antyder ikke muligheden af at anvende det foran omtalte andet lag af stof til dette formål.It was also recognized that forming such strips of granular material is complicated because varying stretching of the web may occur, since its material will be extended under tensile stress (column 6, 1-2), whereby the stripes becomes deformed. The patent suggests various ways of reducing this problem, but does not suggest the possibility of using the aforementioned second layer of fabric for this purpose.
Der er en tendens til, at rækker af aflejret granuleret materiale bliver deformeret til vinkelform, når banen trækkes ind i det apparatur, der skal tildanne banen og det pålagte materiale som en cylindrisk filterstav. Et sådant vinkelmønster dannes ikke ved uensartet strækning af materialet i banen men snarere fordi den midterste del af banen løber med større hastighed end kanterne når den går ind i apparaturet og begynder at blive samlet til en filterstav.There is a tendency for rows of deposited granular material to deform into angular shape as the web is drawn into the apparatus which is to form the web and the applied material as a cylindrical filter rod. Such an angular pattern is not formed by uneven stretching of the material in the web but rather because the middle portion of the web runs at a greater velocity than the edges as it enters the apparatus and begins to assemble into a filter rod.
Et sådant vinkelmønster giver den uheldige virkning, at det granulerede materiale bliver spredt over en betydelig længde af filterstaven, endog i en sådan grad, at granuleret materiale, når staven overskæres til enkelte filterpropper, vil vise sig ved disse' proppers snitflader. Herved vil det granulerede materiale frembringe en uheldig smag.Such an angular pattern gives the unfortunate effect that the granulated material is spread over a considerable length of the filter rod, even to such an extent that when the rod is cut into individual filter plugs, granulated material will appear at the cut surfaces of these plugs. Thereby the granulated material will produce an unfortunate taste.
Formålet med opfindelsen er at angive en ny og forbedret fremgangsmåde og et apparat til fremstilling af filtre med granuleret materiale, hvorved de foran nævnte vanskeligheder afhjælpes eller reduceres. Nærmere betegnet er det formålet med opfindelsen at angive en fremgangsmåde og midler til en hurtigt arbejdende kommerciel fremstilling af filtre, hvor det granulerede materiale er aflejret som en veldefineret mængde med en veldefineret position, således at det hverken falder ud under fremstillingen eller forskubbes til uønskede områder i filteret.The object of the invention is to provide a new and improved method and apparatus for making filters with granular material, thereby alleviating or reducing the aforementioned difficulties. More particularly, the object of the invention is to provide a method and means for a fast-acting commercial preparation of filters, wherein the granulated material is deposited as a well-defined amount with a well-defined position so that it does not fall out during manufacture or be shifted to undesirable areas. in the filter.
Fremgangsmåden ifølge opfindelsen er ejendommelig ved, at den udøves som angivet i krav 1.The method according to the invention is characterized in that it is carried out as claimed in claim 1.
Apparatet ifølge opfindelsen er ejendommelig ved den i krav 10 angivne udformning.The apparatus according to the invention is characterized by the configuration of claim 10.
Opfindelsen vil blive forklaret nærmere ved den følgende beskrivelse af en udførelsesform, idet der henvises til tegningen, hvor 5 146814 fig. 1 viser apparatet ifølge opfindelsen, set fra siden, fig. 2 perspektivisk i større målestok en del af dette apparat, fig. 3 et lodret snit gennem den i apparatet indeholdte mekanisme til afgivelse af granuleret materiale, fig. 4 et tværsnit gennem den første banesektion med derpå afsat granuleret materiale i adskilte bunker, medens fig. 5 viser et tilsvarende snit på et sted, hvor de to banesek-tioner er blevet ført sammen.The invention will be explained in greater detail by the following description of an embodiment, with reference to the drawing, in which fig. 1 is a side view of the apparatus according to the invention; FIG. 2 is a perspective view on a larger scale of a part of this apparatus; FIG. Fig. 3 is a vertical section through the mechanism for dispensing granulated material contained in the apparatus; 4 is a cross-section through the first web section with granulated material deposited thereon in separate piles, while FIG. Figure 5 shows a corresponding section at a location where the two web sections have been joined.
Det i fig. 1 viste apparat 10 til fremstilling af filterpropper består af et aggregat 12 til afgivelse af banemateriale, en skæremekanisme 14, fremføringsaggregater 16 og 17 for henholdsvis den første og den anden banesektion, et aggregat 20 til afgivelse af omslag, et aggregat 22 til dannelse af filterstave, samt et aggregat 24 til afskæring af filterpropper.The FIG. 1, filter plug manufacturing apparatus 10 shown in Fig. 1 consists of a web material dispensing unit 12, a cutting mechanism 14, feed assemblies 16 and 17 for the first and second web sections, a wrapper delivery unit 20, and a filter rod assembly 22, respectively. , as well as an assembly 24 for cutting filter plugs.
I apparatet fremføres en bane 26 af fibrøst celluloseacetat. Der vil imidlertid også kunne anvendes andre passende materialer, såsom papir, garn, eller filamentstrenge.In the apparatus, a web 26 of fibrous cellulose acetate is fed. However, other suitable materials, such as paper, yarn, or filament strings, may also be used.
Det materiale, der skal aflejres på banen 26, må have de ønskede egenskaber med hensyn til absorption og adsorption og må bestå af større eller mindre korn. Dette materiale kan være findelt trækul, silicagel, vulkanske salte, organiske ionbyttere, ler eller lignende materiale. Fortrinsvis anvendes en ionbytter "DUOLITE", der kan være af den art, som er omhandlet i beskrivelsen til U.S.A. patent nr. 3.716.500, udstedt den 13. februar 1973.The material to be deposited on the web 26 must have the desired absorption and adsorption properties and must consist of larger or smaller grains. This material can be finely divided charcoal, silica gel, volcanic salts, organic ion exchangers, clay or similar material. Preferably, an ion exchanger "DUOLITE" may be used which may be of the kind disclosed in the specification to U.S.A. Patent No. 3,716,500, issued February 13, 1973.
Aggregatet 12 er bestemt til at sætte banen 26 af filtermateriale under trækspænding og at sprede banen til en forud fastlagt bredde. Fortrinsvis bliver en kontinuert streng af celluloseacetat med langstrakt akse trukket ud fra en sædvanlig lagerballe i aggregatet 12 til udbredning og plastificering, til dannelse af banen 26. I dette aggregat bliver materialet spredt på sædvanlig måde til en bane 26 med en bredde på omtrent 25 cm. Den åbnede bane 26 6 146814 passerer derefter gennem en sædvanlig ikke vist mekanisme til påføring af plastificeringsmiddel, i forbindelse med cellulose-acetat sædvanligvis triacetin.The assembly 12 is intended to set the web 26 of filter material under tension and to spread the web to a predetermined width. Preferably, a continuous strand of elongated axis cellulose acetate is drawn from a conventional storage bale in the propagation and plasticizer assembly 12 to form the web 26. In this aggregate, the material is spread in the usual manner to a web 26 having a width of about 25 cm. . The opened lane 26 then passes through a conventional plasticizer application mechanism not shown, in conjunction with cellulose acetate usually triacetin.
På denne måde bliver de to banesektioner, i hvilken banen derefter bliver delt, samtidig sat under spænding og behandlet til udbredning og plastificering i nøjagtig samme grad. Herved fås filtre af høj kvalitet med den ensartethed, der kræves ved industriel oigaretfremstilling.In this way, the two web sections into which the web is then divided are simultaneously placed under tension and processed for propagation and plasticization to the exact same degree. This provides high quality filters with the uniformity required in industrial oigarette manufacturing.
Banen 26 bliver delt på langs i to banesektioner 28 og 30 ved hjælp af skæremekanismen 14. Denne mekanisme består som vist i fig. 2 af en rulle 34 og et skærehjul 36, der løber imod hinanden omkring akser vinkelret på banens længdeakse.The web 26 is divided longitudinally into two web sections 28 and 30 by the cutting mechanism 14. This mechanism consists as shown in FIG. 2 of a roller 34 and a cutting wheel 36 running against one another about axes perpendicular to the longitudinal axis of the web.
Rullen 34 virker sammen med en valse 32 til at trække banen 26 ud fra aggregatet 12. Skærehjulet 36 er monteret på en aksel 38, der er lejret i apparatets stativ og som drives sammen med rullen 34, således at kanten af skærehjulet 36 vil løbe imod rullen 34 og overskære banen 26, idet hjulet 36 i realiteten knuser fibrene i banen.The roller 34 cooperates with a roller 32 to pull the web 26 out of the assembly 12. The cutting wheel 36 is mounted on a shaft 38 which is mounted in the frame of the apparatus and which is driven together with the roller 34 so that the edge of the cutting wheel 36 will run against the roller 34 and cutting the web 26, the wheel 36 essentially crushing the fibers in the web.
Transportaggregatet 16, der tjener til at føre den første banesektion 28 gennem påføringsmekanismen 18, består af valsen 32, en lederulle 40, en båndtransportør 42 samt to ruller 44 og 46, anbragt på hver sin side af mekanismen 18.The conveyor assembly 16 which serves to pass the first web section 28 through the application mechanism 18 consists of the roller 32, a guide roller 40, a belt conveyor 42, and two rollers 44 and 46 disposed on either side of the mechanism 18.
Den første banesektion 28 føres fra valsen 32 omkring lederullen 40 og under rullen 44, der er anbragt lige over et endeløst bånd 43. Båndet 43 løber under rullerne 44 og 46, således at den første sektion 28 bliver ført under rullerne 44 og 46 og hviler på båndet 43 tinder bevægelsen gennem mekanismen 18. På denne måde bliver den første banesektion 28 ført i udfladet tilstand gennem mekanismen 18 til modtagelse af det granulerede materiale.The first web section 28 is guided from the roll 32 around the guide roller 40 and under the roller 44 which is placed just above an endless belt 43. The belt 43 runs under the rollers 44 and 46 so that the first section 28 is guided under the rollers 44 and 46 and rests on the belt 43, the movement peaks through the mechanism 18. In this way, the first web section 28 is guided in flattened condition through the mechanism 18 to receive the granulated material.
Transportaggregatet 17, der tjener til at føre den anden banesektion 30 ind over den første banesektion 28 efter mekanismen 18, består af valsen 32, en ledebane 48 samt rullen 46. Den anden banesektion 30 føres, for at undgå komplicerede arrangementer med ruller og styr, hen over mekanismen 18. Den anden banesektion 30 7 14681Λ kan på denne måde ved hjælp af en enkelt lederulle 48 føres hen til den tilstræbte stilling over den første banesektion 28 med det derpå aflejrede granulerede materiale.The conveying assembly 17, which serves to guide the second web section 30 over the first web section 28 according to the mechanism 18, consists of the roller 32, a guide web 48 and the roller 46. The second web section 30 is guided to avoid complicated roll and guide arrangements, over the mechanism 18. The second web section 30 7 14681Λ can thus be guided by a single guide roller 48 to the desired position over the first web section 28 with the granulated material deposited thereon.
Mekanismen 18 til afgivelse af granuleret materiale består som vist i fig. 3 af en tragt 50, en udmålingsmekanisme 52 samt midler 54 til tilslutning af vakuum, der skal suge det granulerede materiale ned på banen fra mekanismen 52 og fastholde det der over en vis strækning. Vakuumorganerne 54 er ikke vist i enkeltheder, men er af sædvanlig art. De viste sugeåbninger 56 vil i visse tilfælde kunne findes helt hen til rullen 46.The mechanism 18 for dispensing granulated material consists as shown in FIG. 3 of a hopper 50, a metering mechanism 52, and vacuum 54 means 54 for sucking the granulated material down the web from the mechanism 52 and holding it there for a certain distance. Vacuum means 54 are not shown in detail but are of the usual nature. The suction openings 56 shown may in certain cases be located all the way to the roll 46.
Udmålingsmekanismen 52 består af en drejelig cylinder 58 i et stationært cylindrisk hus 60. Huset 60 er tilpasset således, at cylinderen 58 går med let glidepasning i huset.The metering mechanism 52 consists of a rotatable cylinder 58 in a stationary cylindrical housing 60. The housing 60 is adapted so that the cylinder 58 is easily slid into the housing.
Cylinderen 58 har et antal udsparinger 62 anbragt i sæt der er fordelt aksialt på cylinderen 58. Hvert af sættene indeholder et antal udsparinger regelmæssigt fordelt langs cylinderens omkreds. Huset 60 har et par porte 64 ud for hvert sæt udsparinger 62 til overføring af det granulerede materiale fra tragten 50 til udsparingerne 62 og derfra til banesektionen 28.Cylinder 58 has a number of recesses 62 disposed in sets axially distributed on cylinder 58. Each of the sets contains a number of recesses regularly distributed along the circumference of the cylinder. The housing 60 has a pair of ports 64 next to each set of recesses 62 for transferring the granulated material from the hopper 50 to the recesses 62 and thence to the web section 28.
Tragten 50 har et antal åbninger 65, der hver flugter med en af de øvre porte 64 i huset 60. Det granulerede materiale passerer gennem åbningerne 65 og portene 64 ned i usparingerne 62. Materialehøjden i tragten 50 kan opretholdes ved sædvanlige midler.The hopper 50 has a plurality of openings 65, each flush with one of the upper ports 64 of the housing 60. The granulated material passes through the openings 65 and the gates 64 into the recesses 62. The material height of the hopper 50 can be maintained by usual means.
Cylinderen 58 drives i synkronisme med fremføringen af banesektionen 28, således at udsparingerne 62 i forbindelse med afgangsportene 64 vil afsætte granuleret materiale i rækker tværs over banen 28, se fig. 4, og således, at rækkerne har forud fastlagte \.The cylinder 58 is operated in synchronism with the advance of the web section 28, so that the recesses 62 in connection with the exit ports 64 will deposit granular material in rows across the web 28, see fig. 4 and so that the rows have predetermined \.
mellemrum i banens længderetning, se fig. 3.gaps in the longitudinal direction of the web, see fig. Third
De to sammenliggende banesektioner 28 og 30 med mellemliggende granuleret materiale, se fig. 5, bliver tildannet som en cylindrisk filterstav i et aggregat 22. Dette er fortrinsvis udført som et sædvanligt garnitureaggregat.The two adjacent web sections 28 and 30 with intermediate granulated material, see FIG. 5, is formed as a cylindrical filter rod in an assembly 22. This is preferably carried out as a conventional garnish assembly.
Den cylindriske filterstav passerer derefter gennem en skæremeka- 8 146314 nisme 24, i hvilken staven på sædvanlig måde udskæres i enkelte filterpropper.The cylindrical filter rod then passes through a cutting mechanism 24 in which the rod is cut in the usual manner into individual filter plugs.
Ved fremgangsmåde ifølge opfindelsen tilvejebringes der en bane af filtermateriale, der er kontinuert i banens akseretning. Banen består fortrinsvis af celluloseacetat, men kan som foran nævnt også bestå af andet materiale. Banen udbredes i tværretningen til en forud fastlagt bredde, f.eks. ca. 25 cm. Derefter påføres plastifi-ceringsmiddel. Disse funktioner sker i aggregatet 12, fig. 1.In the method of the invention, a web of filter material is provided which is continuous in the axis direction of the web. The web preferably consists of cellulose acetate, but may, as mentioned above, also consist of other material. The web is propagated in the transverse direction to a predetermined width, e.g. ca. 25 cm. Then, plasticizer is applied. These functions occur in the assembly 12, fig. First
Derefter gennemskæres banen langs en linie parallel med længderetningen til dannelse af to kontinuerte banesektioner. Banen 26 gennemskæres af skærehjulet 36» der drives med anlæg imod rullen 34. Den første banesektion 28 føres i en første aksial retning i udfladet tilstand til en aflejringsposition. Fremføringen af den første banesektion 28 kan ske kontinuerligt som vist eller intermitterende. I det sidste tilfælde anvendes sædvanlige aggregater til intermitterende fremføring.Then, the web is intersected along a line parallel to the longitudinal direction to form two continuous web sections. The web 26 is intersected by the cutting wheel 36 "which is driven by abutment against the roller 34. The first web section 28 is guided in a first axial direction in the flattened state to a deposition position. The first web section 28 can be advanced continuously as shown or intermittently. In the latter case, customary aggregates are used for intermittent feeding.
Det løse granulerede materiale afgives ved aflejringspositionen på den første banesektion 28 i rækker på tværs af denne, adskilt med regelmæssige aksiale mellemrum. Rækkerne af granuleret materiale strækker sig fortrinsvis i en retning vinkelret på aksen i den første banesektion 28 og består af adskilte materialeaflejringer. Det er imidlertid også muligt at tilvejebringe kontinuerte rækker af granuleret materiale, men de bedste resul·tater opnås ved anvendelse af adskilte aflejringer. Fortrinsvis tilvejebringes et undertryksområde under banen i aflejringsområdet for at medvirke til forøgelse af aflejringshastigheden og til fastholdelse af materialet på banesektionen 28. Dette sker ved den viste udførelsesform ved sugning gennem åbningerne 56.The loose granulated material is discharged at the deposition position of the first web section 28 in rows across it, separated at regular axial intervals. The rows of granulated material preferably extend in a direction perpendicular to the axis of the first web section 28 and consist of separate material deposits. However, it is also possible to provide continuous rows of granulated material, but the best results are obtained by using separate deposits. Preferably, a negative pressure area is provided below the web in the deposition area to assist in increasing the deposition rate and to retain the material on the web section 28. This is done in the illustrated embodiment by suction through the openings 56.
Det granulerede materiale bliver ved aflejringen udmålt på en sådan måde, at der afgives en ønsket mængde af materialet i hver af de enkelte rækker. Denne udmåling kan ske på forskellig måde, f.eks. ved valg mellem udsparinger 62 af forskellig størrelse.At the deposition, the granulated material is measured in such a way that a desired amount of the material is delivered in each of the individual rows. This measurement can be done in different ways, e.g. when choosing between recesses 62 of different sizes.
Nøjagtig og regelmæssig udmåling opnås ved anvendelse af adskilte aflejringer i stedet for en kontinuert stribe af granuleret materiale.Accurate and regular measurement is achieved by using separate deposits instead of a continuous strip of granulated material.

Ifølge fremgangsmåden føres endvidere den anden banesektion 30 i en anden aksial retning uden om aflejringspositionen til overliggende stilling over det aflejrede materiale og den første banesektion, hvorved materialet vil blive anbragt med regelmæssige mellemrum mellem de to banesektioner 28 og 30.Furthermore, according to the method, the second web section 30 is moved in a different axial direction outside the deposition position to the overlying position of the deposited material and the first web section, whereby the material will be arranged at regular intervals between the two web sections 28 and 30.
De to banesektioner 28 og 30 og hver mellemliggende række af granuleret materiale samles til en cylindrisk. filterstav. Dette sker fortrinsvis umiddelbart efter afsætningen af det granulerede materiale på den første banesektion 28 og sammenføringen af de to banesektioner.The two web sections 28 and 30 and each intermediate row of granulated material are assembled into a cylindrical one. filter rod. This preferably occurs immediately after deposition of the granulated material on the first web section 28 and the joining of the two web sections.
