At least one of these tobacco sheets is essentially obtained from 75 to 100% by weight of tobacco-inherent constituents including tobacco extract obtained from leaf or cut tobacco blend and tobacco rib material, and tobacco cellulose obtained from cut tobacco blend or scrap and stalk or rib material where the ratio of leaf and scrap material to stalk and rib material is in the range of 1:1.1 to 1:5.

Description

Die Erfindung betrifft ein stabförmiges Rauchprodukt mit einem strangförmigen Kern aus zerkleinertem Rauchtabak, der von einem Mantel aus nach einem Papierherstellungsverfahren hergestellten Tabakfolien umgeben ist.The invention relates to a rod-shaped smoking product with a strand-shaped core made from shredded smoking tobacco, which is surrounded by a jacket made of tobacco foils produced by a paper manufacturing process.

Ein derartiges Rauchprodukt ist beispielsweise aus der EP-A-0 495 567 bekannt, wobei die Tabakfolie, die auch als ein Blatt aus rekonstituiertem Tabak bezeichnet wird, nach einem Papierherstellungsverfahren gemäß US-A-4,182,349 hergestellt worden ist. Bei einem derartigen Verfahren werden grundsätzlich in einer ersten Stufe Stengel der Tabakpflanze, Tabakrippen und andere bei der Cigarettenherstellung nicht verwertbare Tabakbestandteile insbesondere Feinstanteile aber auch Tabakblätter zerfasert und mit beispielsweise erwärmtem Wasser oder anderen wässrigen Flüssigkeiten bestimmter Temperaturen vermischt bzw. ausgewaschen, wonach mittels einer Siebvorrichtung der die wasserlöslichen Bestandteile enthaltende Extrakt abgezogen wird; in einer zweiten Stufe werden die Cellulosebestandteile gegebenenfalls nach weiteren Zwischenstufen wie Homogenisieren, nochmaligem Sieben oder Reinigen, zusammen mit Füllstoffen und anderen Zusätzen nach weiteren Zwischenstufen auf das Sieb einer Papierherstellungsvorrichtung gegeben. Auf die so erhaltene Rohfolie wird der eingeengte Tabak-Extrakt aufgebracht und diese zur endgültigen Tabakfolie verarbeitet.Such a smoking product is known, for example, from EP-A-0 495 567, the tobacco foil, which is also referred to as a sheet of reconstituted tobacco, having been produced by a paper production process in accordance with US-A-4,182,349. With such a method, in a first stage, stems of the tobacco plant, tobacco ribs and other tobacco components that cannot be used in cigarette production, in particular very fine fractions but also tobacco leaves, are defibrated and mixed or washed out with, for example, heated water or other aqueous liquids of certain temperatures, after which the sieve device is used to filter them the water-containing extract extract is withdrawn; in a second stage, the cellulose constituents are optionally repeated after further intermediate stages such as homogenization Sieving or cleaning, together with fillers and other additives, are added to the sieve of a paper production device after further intermediate stages. The concentrated tobacco extract is applied to the raw film thus obtained and this is processed into the final tobacco film.

Die nach derartigen Extrakt-Verfahren hergestellten Tabakfolien wurden bislang einmal in kleingeschnittener Form zur Streckung von Rauchtabak in Cigaretten oder Cigarillos eingesetzt, wobei man in erster Linie die für die Cigarettenherstellung ungeeigneten Feinanteile und Rippen als rauchbares Material einsetzen konnte. Zum anderen wurden derartige Tabakfolien wegen ihrer gleichmäßigen Struktur und besseren mechanischen Eigenschaften als Deckblätter für Cigarillos verwendet.The tobacco foils produced according to such an extract process have so far been used in small chunks for stretching smoking tobacco in cigarettes or cigarillos, primarily using the fines and ribs which are unsuitable for cigarette manufacture as a smokable material. On the other hand, tobacco foils of this type were used as cover sheets for cigarillos because of their uniform structure and better mechanical properties.

Der Einsatz von Tabakfolien als Umblatt oder Deckblatt für Rauchprodukte ist aus vielerlei Gründen problematisch, weil die Tabakfolien aufgrund des Tabakausgangsmaterials sensorisch unzureichend und/oder wegen der dunkleren Färbung für den Verbraucher wenig ansprechend sind. Es sind zahlreiche Versuche unternommen worden, diese Nachteile zu beheben, wie beispielsweise durch enzymatische Aufbereitung des Extraktes. Derartige Maßnahmen waren bislang wenig erfolgreich und führten auch zu Produkten, die gesetzlichen Bestimmungen nicht entsprachen. Darüber hinaus ergaben sich erhebliche Schwierigkeiten hinsichtlich der geforderten Eigenschaften derartiger Tabakfolien hinsichtlich ihrer Reißfestigkeit, ihrer Wasserbeständigkeit bzw. Speichelfestigkeit oder ganz allgemein hinsichtlich ihrer Raucheigenschaften, wie Porosität, Abbrennverhalten, Aschegehalt und insbesondere hinsichtlich des vom Verbraucher gewohnten Raucharomas.The use of tobacco foils as a binder or cover sheet for smoking products is problematic for many reasons, because the tobacco foils are inadequate in terms of sensors due to the tobacco starting material and / or because of the darker color they are not appealing to the consumer. Numerous attempts have been made to overcome these disadvantages, for example by enzymatically processing the extract. Such measures have so far been unsuccessful and have also resulted in products that do not meet legal requirements. In addition, there were considerable difficulties with the required properties of such tobacco films with regard to their tear resistance, their water resistance or saliva resistance or very generally with regard to their smoking properties, such as porosity, burning behavior, ash content and in particular with regard to the smoke aroma familiar from the consumer.

Bei dem vorbekannten Rauchprodukt gemäß EP-A-0 495 567 wird die Tabakfolie nach dem Extraktions-Papierverfahren im wesentlichen aus Rippen und Feinanteilen erhalten, wobei zur Reduzierung von Nebenrauch der nach diesem Papierherstellungsverfahren erhaltene Extrakt nur in einer begrenzten Menge, nämlich nicht über 20 Gew.% (bezogen auf das Gewicht der Tabakfolie) wieder aufgebracht werden soll. Demzufolge läßt die geschmackliche Qualität oder das Aroma eines derartigen Produktes zu wünschen übrig.In the previously known smoking product according to EP-A-0 495 567, the tobacco film is obtained essentially from ribs and fine fractions by the extraction paper process, the extract obtained by this paper production process being reduced in order to reduce secondary smoke, only in a limited amount, namely not more than 20% by weight .% (based on the weight of the tobacco foil) should be applied again. As a result, the taste quality or aroma of such a product leaves something to be desired.

Diese Produkte haben den Nachteil, daß einmal das zur Herstellung der Tabakfolien eingesetzte Tabakmaterial zu unliebsamen Geschmacksrichtungen führt und der aufdringliche und schwere Geruch des Nebenrauches von vielen Rauchern nicht akzeptiert wird. Diese geschmackliche und ebenso die geruchliche Beeinträchtigung wird bei einem Tabakprodukt mit einer Ummantelung aus beispielsweise zwei Tabakfolien noch verstärkt, weil diese etwa 20 Gew.% des Tabakproduktes gegenüber dem Kern aus zerkleinertem Rauchtabak ausmachen und somit den Geschmackseindruck des Hauptrauches erheblich beeinflussen bzw. mindern, ebenso den Geruchseindruck des Nebenrauches.These products have the disadvantage that the tobacco material used to produce the tobacco foils leads to unpleasant flavors and the obtrusive and heavy smell of secondary smoke is not accepted by many smokers. This taste and also the olfactory impairment is further increased in a tobacco product with a casing made of, for example, two tobacco foils, because these account for about 20% by weight of the tobacco product compared to the core of shredded smoking tobacco and thus considerably influence or reduce the taste impression of the main smoke, as well the smell impression of the secondary smoke.

Der Erfindung liegt die Aufgabe zugrunde, ein neuartiges Rauchprodukt der eingangs erwähnten Art vorzuschlagen, welches einmal die vom Raucher erwartete typische Geschmacksrichtung befriedigt, die bislang von mit Tabakfolien ummantelten Rauchprodukten nicht erreicht werden konnte, und welches zum anderen die Qualität des Nebenrauches verbessert. Letzlich wird ein derart ummanteltes Rauchprodukt vorgeschlagen, bei dem der aus Tabakfolien gebildete Mantel hinsichtlich der physikalischen Folien-Kenndaten so ausgebildet ist, daß das Rauchprodukt auf üblichen Cigaretten- bzw. Cigarillo-Fertigungsanlagen wirtschaftlich hergestellt werden kann und somit die Anforderungen bezüglich Reißfestigkeit und Dehnung einer derartigen Mantelherstellung erfüllt, wobei ferner Glimmgeschwindigkeit und Porosität eine Steuerung des Rauchangebots ermöglichen.The invention is based on the object of proposing a novel smoking product of the type mentioned at the outset which once satisfies the typical flavor expected by the smoker, which until now could not be achieved by tobacco wrapped smoke products, and which on the other hand improves the quality of the secondary smoke. Ultimately, a smoke product encased in this way is proposed, in which the casing formed from tobacco foils is designed with regard to the physical characteristics of the foil so that the smoke product can be produced economically on conventional cigarette or cigarillo production systems and thus meet the requirements with regard to tensile strength and elongation such jacket production fulfilled, with the glow rate and porosity allow control of the smoke supply.

Zur Lösung dieser Aufgabe wird daher ein Rauchprodukt vorgeschlagen, welches gemäß Hauptanspruch gestaltet ist, wobei besonders bevorzugte Ausführungen in den Unteransprüchen aufgeführt sind. Insbesondere wird auch die Verwendung der Rauchprodukte als neuartige Steckcigarillos vorgeschlagen.To solve this problem, a smoking product is therefore proposed which is designed according to the main claim, particularly preferred embodiments being set out in the subclaims. In particular, the use of smoking products as novel plug-in cigarillos is also proposed.

Grundsätzlich ist bei der Herstellung der Tabakfolien des stabförmigen Rauchproduktes gemäß Erfindung zwischen zwei unterschiedlichen Papierherstellungsverfahren zu unterscheiden, zum einen das eingangs beschriebene als "TF-1" bezeichnete Verfahren mit anteiliger Extraktrückführung und Einsatz von Tabakstengeln oder von Tabakstengel- bzw. Tabakrippenmaterial und Lamina-Tabakmaterial, sowie zum anderen ein für die Tabakfolienherstellung neues und als "TF-2" bezeichnetes Verfahren ohne Extraktrückführung und Einsatz von ausschließlich Lamina-Tabakmaterial, verbunden mit einem nahezu quantitativen Umlauf kaltwasserlöslicher Tabakauszüge in der Siebpartie einer Papierherstellungsanlage.Basically, in the manufacture of the tobacco foils of the rod-shaped smoking product according to the invention, a distinction must be made between two different paper production processes, on the one hand the process described at the outset as "TF-1" with proportionate extract recycling and use of Tobacco stalks or of tobacco stem or rib tobacco material and lamina tobacco material, as well as a new process for tobacco foil production and called "TF-2" without extract recycling and the use of only lamina tobacco material, combined with an almost quantitative circulation of cold water-soluble tobacco extracts in the Screen section of a paper production plant.

Vorzugsweise werden die Tabakfolien für das Deckblatt, also der äußeren Umhüllung des stabförmigen Rauchproduktes, nach dem "TF-1"-Verfahren und die für das Umblatt, also der (inneren) Umhüllung des Kerns des stabförmigen Rauchproduktes, nach dem "TF-2"-Verfahren gefertigt. Dies ergibt überraschenderweise eine geruchliche Besserstellung des Nebenrauches des erfindungsgemäßen Produktes gegenüber dem Nebenrauch von herkömmlichen, vergleichbaren Produkten wie handelsüblichen Cigarillos. Dabei wird jedoch nicht die Menge des Nebenrauches, sondern ausschließlich seine geruchliche Qualität entscheidend verbessert; der Nebenrauch verliert seine aufdringliche, von vielen Rauchern nicht akzeptierte, dunkle, duffe Note.The tobacco foils for the cover sheet, ie the outer wrapping of the rod-shaped smoke product, are preferably produced according to the "TF-1" method and those for the wrapper, ie the (inner) wrapping of the core of the rod-shaped smoke product, according to the "TF-2" -Procedure manufactured. This surprisingly results in an improved odor of the secondary smoke of the product according to the invention compared to the secondary smoke of conventional, comparable products such as commercially available cigarillos. However, it is not the amount of secondary smoke that is significantly improved, but only its olfactory quality; the secondary smoke loses its intrusive, dark, fragrant note, which is not accepted by many smokers.

Dieser Effekt kann aber auch wiederum unerwarteterweise erzielt werden mit einer anderen, bevorzugten Ausführungsform gemäß Erfindung, bei der ausschließlich Tabakfolien nach "TF-1" eingesetzt werden, wobei jedoch der Deckblatt-Tabakfolie erheblich mehr Tabakextrakt zu- bzw. rückgeführt wird als der Umblatt-Tabakfolie. Insgesamt enthält dann der hier aus zwei Lagen bestehende Mantel des stabförmigen Rauchproduktes bezogen auf die Trockensubstanz eine Tabakextrakt-Menge von mehr als 20 Gew.%.This effect can, however, also be achieved unexpectedly with another preferred embodiment according to the invention, in which only tobacco foils according to "TF-1" are used, but the tobacco wrapper of the topsheet is fed or returned considerably more tobacco extract than the binder. Tobacco foil. In total, the jacket of the rod-shaped smoking product consisting of two layers contains a tobacco extract amount of more than 20% by weight, based on the dry substance.

Letztlich sind auch Kombinationen der nach beiden Verfahren hergestellten Tabakfolien zur Fertigung des stabförmigen Rauchproduktes gemäß Erfindung möglich, die zumindest anteilig die vorteilhaften, überraschenden Effekte ergeben, was den Rauchern von beispielsweise "klassischen" Cigarillos den Umstieg auf das erfindungsgemäße Produkt vermutlich erleichtert.Ultimately, combinations of the tobacco foils produced by the two methods for producing the rod-shaped smoking product according to the invention are also possible, which at least partially result in the advantageous, surprising effects, which presumably makes it easier for smokers of, for example, "classic" cigarillos to switch to the product according to the invention.

Tabakfolie nach TF-1Tobacco film according to TF-1

Zur Herstellung des stabförmigen Rauchproduktes gemäß Erfindung ist es wesentlich, daß die nach dem Papierherstellungsverfahren gemäß TF-1 hergestellte Tabakfolie zu 75 bis 100 Gew.% aus im wesentlichen aus (a) Tabakcellulose und (b) Tabakextrakt bestehenden tabakeigenen Bestandteilen besteht. Die Tabakcellulose wird aus einer zerkleinerten Blatt- oder Schnitt-Tabakmischung, aus Tabakgrus (scrap), aus Tabakstengeln und aus Tabakrippenmaterial erhalten, wobei die aromaintensiven Komponenten, nämlich die Blatt-Tabakmischung und der Tabakgrus mit einer Teilchengröße von etwa 1 bis 5 und vorzugsweise 1,5 bis 4 mm einerseits und die für den Celluloseanteil stärker bestimmenden Komponenten, nämlich Tabakrippenmaterial andererseits in einem Gewichtsverhältnis von 1 : 1,1 bis 1 : 5 vorliegen. Der Tabakextrakt wird aus einer zerkleinerten Blatt- oder Schnitt-Tabakmischung und Tabakrippenmaterial erhalten.For the manufacture of the rod-shaped smoking product according to the invention, it is essential that the tobacco film produced by the paper manufacturing process according to TF-1 consists of 75 to 100% by weight essentially of (a) tobacco cellulose and (b) tobacco extract consisting of tobacco components. The tobacco cellulose is obtained from a shredded leaf or cut tobacco mixture, from tobacco greens (scrap), from tobacco stems and from tobacco stem material, the aroma-intensive components, namely the leaf tobacco mixture and the tobacco greens having a particle size of about 1 to 5 and preferably 1 , 5 to 4 mm on the one hand and the components which are more determining for the cellulose content, namely tobacco rib material on the other hand, are present in a weight ratio of 1: 1.1 to 1: 5. The tobacco extract is made from a shredded leaf or cut tobacco mixture and received tobacco rib material.

Ferner werden zur Herstelung der Tabakfolien bis zu 20 Gew.% und vorzugsweise 8 bis 14 Gew.% Fremdcellulose wie Weichholz-, Hanf- bzw. Flachs-Cellulose eingesetzt. Wenn die Tabakcellulose vollständig oder teilweise aus Tabakstengeln herrührt, kann der Anteil an Fremdcellulose ohne Beeinträchtigung der physikalischen Eigenschaften der Tabakfolie entsprechend verringert werden.Furthermore, up to 20% by weight and preferably 8 to 14% by weight of foreign cellulose such as softwood, hemp or flax cellulose are used to produce the tobacco films. If the tobacco cellulose comes wholly or partly from tobacco stalks, the proportion of foreign cellulose can be reduced accordingly without impairing the physical properties of the tobacco film.

Es ist vorteilhaft, wenn zur Herstellung dieser Tabakfolie etwas weniger als die Hälfte des zur Herstellung der Tabakfolie erforderlichen Tabakmaterials aus einer hochwertigen Schnitt-Tabakmischung besteht, die beispielsweise aus einer Mischung aus Virginia-Tabak, Burley-Tabak, Orient-Tabak und Blährippen von Virginia-Tabak besteht.It is advantageous if a little less than half of the tobacco material required to produce the tobacco foil consists of a high-quality cut tobacco mixture, for example a mixture of Virginia tobacco, Burley tobacco, Orient tobacco and blowing ribs from Virginia -Tobacco exists.

Bezüglich der Tabakcellulose liegt der zur Herstellung der Tabakfolie erforderliche Anteil an Tabakrippenmaterial etwas höher, was im Hinblick auf die physikalischen Eigenschaften der Tabakcellulose erforderlich ist. Allerdings soll das Verhältnis von Blatt- bzw. Schnitt-Tabakmischung zu Tabakrippen- bzw. Tabakstengelmaterial nicht einen Wert von 1 : 5 überschreiten, da sonst die aromabestimmten Raucheigenschaften der Tabakfolie nachteilig beeinflußt werden. Gegebenenfalls kann dies jedoch durch die Zugabe von tabakeigenen Aromen während des letzten Schrittes des Folienfertigungsprozesses kompensiert werden.With regard to tobacco cellulose, the proportion of tobacco rib material required to produce the tobacco film is somewhat higher, which is necessary in view of the physical properties of the tobacco cellulose. However, the ratio of leaf or cut tobacco mixture to tobacco stem or tobacco stem material should not exceed a value of 1: 5, since otherwise the flavor-determined smoking properties of the tobacco foil are adversely affected. If necessary, however, this can be compensated for by adding tobacco flavors during the last step of the film production process.

Wesentlich ist, daß bei der Herstellung der Tabakfolie der Extrakt in einer Menge von mehr als 20 Gew.% der Tabakfolie auf das bei diesem Verfahren erhaltene Cellulosematerial aufgebracht wird. Wenn der Extrakt einen erhöhten Anteil eines Lamina-Tabakextraktes enthält, werden die für das endgültige Rauchprodukt erforderlichen Aromabestandteile angereichert.It is essential that during the manufacture of the tobacco foil the extract is applied to the cellulose material obtained in this process in an amount of more than 20% by weight of the tobacco foil. If the extract contains an increased proportion of a lamina tobacco extract, the aroma components required for the final smoking product are enriched.

Tabakfolie nach TF-2Tobacco film according to TF-2

Diese nach einem anderen Papierherstellungsverfahren gefertigte Tabakfolie besteht bezüglich ihres Tabakanteils im wesentlichen aus Lamina-Tabakmaterial. Dieses wird bezogen auf die Tabakfolie in einer Menge von 75 bis 80 Gew.% zusammen mit 10 bis 20 Gew.% langfaseriger Fremdcellulose zerkleinert und bei nahezu vollständigem Umlauf der kaltwasserlöslichen Tabakauszüge in der Siebpartie einer Papierherstellungsanlage auf dieser als Rohfolie erhalten. Die weiterhin erforderlichen üblichen Zusatzstoffe wie Bindemittel, Füllstoffe und die den Abbrand beeinflussenden Mittel sowie Aromastoffe können in einer Menge bis zu 15 Gew.% sowohl bei Herstellung der Rohfolie als auch später bei der Konditionierung dieser zugesetzt werden.This tobacco film manufactured according to another paper manufacturing process consists essentially of lamina tobacco material with regard to its tobacco content. Based on the tobacco film, this is crushed in an amount of 75 to 80% by weight together with 10 to 20% by weight of long-fiber foreign cellulose and, when the cold-water-soluble tobacco extracts are almost completely circulated in the wire section of a paper production plant, is obtained as raw film on this. The usual additives that are still required, such as binders, fillers and the agents influencing the burn-off, as well as flavorings, can be added in an amount of up to 15% by weight both when the raw film is produced and later when it is conditioned.

Es ist von Vorteil, wenn die Tabakfolie in ihrer geschmacksrelevanten Tabakmischungszusammensetzung der Zusammensetzung der Blatt- bzw. Schnitt-Tabakmischung des Einlegetabaks bzw. des Kernes des stabförmigen Rauchproduktes entspricht. Dies ist einerseits zur Erzielung der gewünschten Geschmacksrichtung - vorzugsweise "American Blend" - erforderlich, andererseits im Hinblick auf eine einfache, kostengünstige Fertigung des stabförmigen Rauchproduktes insgesamt von Vorteil, da mit der gleichen Tabak-Mischung sowohl der Mantel als auch der Kern gefertigt werden können. Man kann auch abweichend davon die Tabakmischungszusammensetzung der Tabakfolie von der Mischungszusammensetzung des Einlegetabaks abändern.It is advantageous if the tobacco film in its taste-relevant tobacco mixture composition corresponds to the composition of the leaf or cut tobacco mixture of the tobacco inlay or the core of the rod-shaped smoking product. This is on the one hand, to achieve the desired taste - preferably "American blend" - necessary, on the other hand, with regard to a simple, inexpensive manufacture of the rod-shaped smoke product, an advantage overall, since both the casing and the core can be produced with the same tobacco mixture. Alternatively, the tobacco mixture composition of the tobacco film can be changed from the mixture composition of the tobacco.

Zur Herstellung der Tabakfolie sowohl nach TF-1 als auch nach TF-2 können noch bis zu 20 Gew.% Fremdcellulose zugesetzt werden, wodurch die physikalischen Eigenschaften der Tabakfolie verbessert werden.Up to 20% by weight of foreign cellulose can be added to produce the tobacco film according to both TF-1 and TF-2, which improves the physical properties of the tobacco film.

Als Zusatzstoffe können bei der Herstellung wiederum beider Tabakfolien nach TF-1 und TF-2 übliche Bindemittel wie Methylcellulose, Dextrine, Pektine, Alginate, Stärke, Gummen, Amylose, Carboxymethylcellulose, Honig, Maissirup oder andere Polysaccharide verwendet werden. Als Füllstoff kann beispielsweise Calciumcarbonat oder Titandioxyd eingesetzt werden. Als Abbrand beeinflussende Mittel werden meist Erdalkalicarbonate und Alkalisalze schwacher organischer Säuren wie Alkalicitrate oder -acetate eingesetzt.In the manufacture of both tobacco films according to TF-1 and TF-2, conventional binders such as methyl cellulose, dextrins, pectins, alginates, starch, gums, amylose, carboxymethyl cellulose, honey, corn syrup or other polysaccharides can be used as additives. Calcium carbonate or titanium dioxide, for example, can be used as filler. Alkaline earth carbonates and alkali salts of weak organic acids, such as alkali citrates or acetates, are mostly used as agents influencing the erosion.

Als Aromastoffe können nachträglich tabakeigene Aromastoffe oder Extrakte aus Tabakmischungen eingesetzt werden, beispielsweise durch eine on-line Beaufschlagung der an sich fertigen Tabakfolien mittels der Beaufschlagungsvorrichtung der Firma Kaymich (GB) (Kaymich-Applikator Modell FDU3 SYSM). Dabei erfolgt der Aromenauftrag vorzugsweise in alkoholischer Lösung, bevorzugt auf die Innenseite der Tabakfolien, um unerwünschte optische Effekte zu vermeiden, ganzflächig oder in Längsstreifen. Diese nachträgliche Folienaromatisierung kann sowohl bei der Tabakfolie gemäß TF-1 durchgeführt werden als auch bei der Tabakfolie gemäß TF-2. Tabelle I Technischen Daten der Tabakfolien TF-1 bzw. TF-2: allgemeiner Bereich vorzugsweise Dehnung in % nach DIN 53112 1 - 1,4 1,15 - 1,3 Porosität nach DIN ISO 2965 in Coresta-Einheiten 30 - 200 80 - 120 Flächengewicht nach DIN 53104 in g/m² 35 - 70 45 - 55 Feuchte nach DIN 10252 in % 8 - 15 8 - 12 Bruchlast nach DIN 53112 in g je 2,54 cm Breite mind. 1000 1350 - 1600 Flavorings that can be used later are tobacco flavors or extracts from tobacco mixtures, for example by an on-line loading of the tobacco foils, which are manufactured per se, by means of the loading device from Kaymich (GB) (Kaymich applicator model FDU3 SYSM). The flavoring is preferably carried out in alcoholic solution, preferably on the inside of the tobacco foils, in order to avoid undesirable optical effects, over the entire surface or in longitudinal strips. This subsequent film flavoring can be carried out both with the tobacco film according to TF-1 and with the tobacco film according to TF-2. Table I Technical data of the tobacco films TF-1 and TF-2: general area preferably Elongation in% according to DIN 53112 1 - 1.4 1.15 - 1.3 Porosity according to DIN ISO 2965 in Coresta units 30-200 80-120 Basis weight according to DIN 53104 in g / m² 35-70 45-55 Humidity according to DIN 10252 in% 8-15 8-12 Breaking load according to DIN 53112 in g each 2.54 cm wide at least 1000 1350 - 1600

Bei einer Ausführungsform der Erfindung ist der strangförmige Kern aus zerkleinertem Rauchtabak mit nur einer nach dem TF-1-Verfahren erhaltenen Tabakfolie ummantelt. Bei einer anderen Ausführungsform der Erfindung besteht der um den strangförmigen Kern gelegte Mantel aus ein oder mehr Lagen Tabakfolie, die sowohl beide nach dem TF-1-Verfahren oder beide nach dem TF-2-Verfahren erhalten worden sind, wobei es allerdings bevorzugt wird, die eine Lage und insbesondere die äußere Lage bzw. das Deckblatt nach dem TF-1-Verfahren herzustellen, während die innere Lage bzw. das Umblatt nach dem TF-2-Verfahren erhalten worden ist. Üblicherweise ist das Deckblatt, also die äußerste um den strangförmigen Kern gebildete Lage des Mantels, spiralförmig angeordnet, während das Umblatt, also die innerste um den strangförmigen Kern gebildete Lage des Mantels, in axialer Richtung eine Klebenaht aufweist.In one embodiment of the invention, the strand-shaped core of shredded smoking tobacco is coated with only one tobacco foil obtained by the TF-1 process. Another one According to one embodiment of the invention, the jacket placed around the strand-shaped core consists of one or more layers of tobacco film, both of which have been obtained by the TF-1 process or both by the TF-2 process, although it is preferred to use one layer and in particular to produce the outer layer or cover sheet by the TF-1 process, while the inner layer or cover sheet has been obtained by the TF-2 process. The cover sheet, that is to say the outermost layer of the jacket formed around the strand-shaped core, is usually arranged in a spiral, while the binder sheet, that is to say the innermost layer of the jacket formed around the strand-shaped core, has an adhesive seam in the axial direction.

Bei einem mit zwei Tabakfolien umhüllten Kern soll dieses Rauchprodukt im allgemeinen die in der folgenden Tabelle II aufgeführten technischen Daten haben: Tabelle II allgemeiner Bereich vorzugsweise Durchmesser in mm 6 - 9 7,8 - 8,1 Länge in mm 50 - 250 55 - 75 Massenglimmgeschwindigkeit in mg/min 50 - 70 60 Stopfdichte des Fülltabaks (Kern) in mg/cm³ 190 - 270 210 - 240 In the case of a core covered with two tobacco foils, this smoking product should generally have the technical data listed in Table II below: Table II general area preferably Diameter in mm 6 - 9 7.8 - 8.1 length in mm 50-250 55-75 Mass glow rate in mg / min 50-70 60 Packing density of the filling tobacco (core) in mg / cm³ 190-270 210-240
