Description

PROCEDE DE GOMMAGE D'UNE FEUILLE DE TABAC RECONSTITUEPROCESS FOR SCRUBBING A RECONSTITUTED TOBACCO LEAF
La présente invention concerne le domaine des articles pour fumeurs. Plus précisément, l'invention concerne le domaine de tels articles utilisant au moins une feuille de tabac reconstitué.The present invention relates to the field of articles for smokers. More specifically, the invention relates to the field of such articles using at least one sheet of reconstituted tobacco.
On a proposé dans la demande de brevet FR-97 15845 de la Demanderesse, un article permettant à un consommateur de préparer lui- même un cigarillo, cet article comprenant notamment un ensemble de feuilles de tabac reconstitué enchevêtrées entre elles pour permettre une distribution automatique par traction successive sur les différentes feuilles.We have proposed in patent application FR-97 15845 of the Applicant, an article allowing a consumer to prepare himself a cigarillo, this article comprising in particular a set of reconstituted tobacco leaves entangled between them to allow automatic distribution by successive pull on the different sheets.
Dans un tel article, les feuilles de tabac reconstitué, appelées encore feuilles de tabac, se voient appliquer un filet de colle sur l'une de leurs bordures. Une fois séché ce filet de colle, les feuilles sont enchevêtrées les unes dans les autres.In such an article, the leaves of reconstituted tobacco, also called tobacco leaves, are applied a thread of glue on one of their edges. Once this glue has dried, the leaves are tangled together.
Le filet de colle permet une fois la feuille roulée sur elle-même, de coller la bordure sur le rouleau ainsi formé. On utilise notamment, en tant que colle, des colles alimentaires permettant à l'utilisateur de coller la bordure à l'aide de sa salive. Dans le cas de feuilles enduites d'un filet de colle alimentaire, la colle utilisée peut être soit une colle à froid déposée à température ambiante et séchée par convection, soit une colle à chaud, par exemple une gomme arabique naturelle ou une colle synthétique déposée à chaud avec séchage par radiation (type infrarouge) localisé au droit du filet de colle, ou dans un four convectif.Once the sheet is rolled up on itself, the glue thread allows the border to be glued onto the roll thus formed. Food glue is used in particular as glue, allowing the user to stick the border using saliva. In the case of sheets coated with a thread of food glue, the glue used can be either a cold glue deposited at room temperature and dried by convection, or a hot glue, for example a natural gum arabic or a synthetic glue deposited hot with radiation drying (infrared type) located at the right of the adhesive stream, or in a convective oven.
Les techniques actuelles de mise en place de tels filets de colle ne sont pas satisfaisantes.Current techniques for placing such glue threads are not satisfactory.
En particulier, il s'avère que la feuille de tabac absorbe la gomme dans une telle proportion que la feuille munie du filet de gomme ne présente que des propriétés d'adhésion médiocres.In particular, it turns out that the tobacco leaf absorbs gum in such a proportion that the leaf provided with the gum net exhibits only poor adhesion properties.
Les feuilles munies d'un filet de colle proposées jusqu'à présent ne permettent de réaliser que des cigarillos particulièrement fragiles. L'invention a pour but principal de proposer une feuille de tabac reconstitué dont le filet de colle garnissant une de ses bordures produise une fixation satisfaisante de cette bordure sur le reste de la feuille.The sheets provided with a thread of glue proposed until now only allow to make particularly fragile cigarillos. The main object of the invention is to propose a reconstituted tobacco sheet, the thread of glue filling one of its edges producing a satisfactory fixing of this edge on the rest of the sheet.
Ce but est atteint dans le cadre de la présente invention grâce à une feuille de tabac reconstitué enduite d'un filet de colle le long d'une de ses bordures, caractérisée en ce que la masse linéaire du filet de colle à l'état sec est supérieure à 70mg/m.This object is achieved in the context of the present invention by means of a reconstituted tobacco sheet coated with a glue stream along one of its edges, characterized in that the linear mass of the glue stream in the dry state is greater than 70mg / m.
Selon un autre aspect de l'invention, on propose un procédé d'application d'un tel filet de colle sur une feuille de tabac reconstitué grâce auquel la feuille de tabac conserve une certaine élasticité après mise en place du filet de colle. En effet, dans le cas des procédés connus d'application d'un filet de colle, on met en œuvre un séchage du filet de colle qui produit également un assèchement de la feuille et le rend cassant. Cet effet fragilisant est tel que la fabrication d'un article à fumer où cette feuille doit être fortement courbée devient quasiment impossible.According to another aspect of the invention, a method of applying such a thread of glue to a sheet of reconstituted tobacco is proposed, by which the tobacco sheet retains a certain elasticity after the glue thread has been put in place. Indeed, in the case of known methods of applying a thread of glue, drying of the glue thread is carried out which also produces drying of the sheet and makes it brittle. This weakening effect is such that the manufacture of a smoking article where this sheet must be strongly curved becomes almost impossible.
Un procédé selon l'invention d'application d'un filet de colle est un procédé dans lequel on sèche la colle par chauffage de la feuille munie de ce filet, et dans lequel on maintient l'humidité de la feuille pendant ce séchage au-delà de 7%. Selon un troisième aspect de l'invention, on propose un dispositif pour la mise en œuvre d'un tel procédé, consistant en un four muni de moyens de translation des feuilles, ces moyens traversant le four, et présentant des moyens de pulvérisation d'eau au niveau de l'entrée du four ainsi qu'au moins une buse soufflant de l'air qui est disposée de façon à souffler sur le filet de colle.A method according to the invention for applying a glue net is a method in which the glue is dried by heating the sheet provided with this net, and in which the humidity of the sheet is maintained during this drying at above 7%. According to a third aspect of the invention, a device is proposed for implementing such a method, consisting of an oven provided with means for translating the sheets, these means passing through the oven, and having means for spraying water at the entrance of the oven as well as at least one air blowing nozzle which is arranged so as to blow on the thread of glue.
D'autres caractéristiques, buts et avantages de la présente invention apparaîtront à la lecture de la description détaillée qui va suivre.Other characteristics, objects and advantages of the present invention will appear on reading the detailed description which follows.
Les gommes proposées jusqu'à présent pour les feuilles de tabac sont sensiblement les mêmes que celles utilisées sur du papier à cigarette classique. Or, ces gommes sont apparues difficiles à utiliser dans cette application spécifique, puisqu'elles ne fournissent qu'une capacité d'accroché particulièrement réduite aux feuilles de tabac. De plus, on dépose de manière habituelle un filet de gomme sur une feuille de tabac selon une masse linéaire de gomme d'environ 40 à 50 mg/m, une telle quantité de colle étant considérée comme une quantité particulièrement élevée. En effet, pour sécher une telle quantité de colle, on doit déjà faire subir aux feuilles un chauffage qui le fragilise particulièrement.The gums proposed so far for tobacco leaves are substantially the same as those used on conventional cigarette paper. However, these gums have appeared difficult to use in this specific application, since they only provide a particularly reduced grip capacity on tobacco leaves. In addition, a thread of gum is usually deposited on a tobacco leaf according to a linear mass of gum of approximately 40 to 50 mg / m, such an amount of glue being considered to be a particularly high amount. In fact, to dry such an amount of glue, the sheets must already be subjected to heating which weakens it particularly.
En effet, la feuille de tabac reconstitué est particulièrement sensible aux variations d'humidité, et en particulier, lors du gommage, le séchage de la gomme par la chaleur fait chuter l'humidité du tabac reconstitué de 14% à environ 4%, ce qui a pour effet de fragiliser la feuille à un point tel qu'il n'est plus possible en pratique de le manipuler sans produire un grand nombre de cassures.Indeed, the reconstituted tobacco leaf is particularly sensitive to variations in humidity, and in particular, during the exfoliation, the drying of the gum by heat causes the humidity of the reconstituted tobacco to drop from 14% to approximately 4%, which which has the effect of weakening the sheet to such an extent that it is no longer possible in practice to handle it without producing a large number of breaks.
De plus, en réduisant le séchage appliqué à la feuille, le premier effet obtenu est que la gomme n'est qu'incomplètement séchée, tandis que la feuille présente déjà une fragilité très gênante.In addition, by reducing the drying applied to the sheet, the first effect obtained is that the gum is only partially dried, while the sheet already has a very troublesome fragility.
Le fait que la gomme ne soit séchée que de manière incomplète produit des collages intempestifs lors du rembobinage de la feuille, ou lors de manipulations ultérieures, ce problème venant s'ajouter à la fragilité de la feuille. Une opération d'enchevètrage devient notamment pratiquement impossible.The fact that the gum is only partially dried produces untimely sticking when rewinding the sheet, or during subsequent handling, this problem being added to the fragility of the sheet. In particular, a tangling operation becomes practically impossible.
Partant de cette situation, les techniciens du domaine des feuilles de tabac reconstitué n'ont pas recherché à augmenter la quantité de colle du filet, une telle augmentation, même très légère, n'étant sensée que présenter des désavantages. Les inventeurs ont pu constater que de manière surprenante, au- delà d'une masse linéaire du filet de colle à l'état sec d'environ 70 mg/m, celui-ci présente des propriétés d'adhésion particulièrement efficaces, et qu'il est possible au-delà d'une telle quantité de colle de réaliser un filet sec sans fragiliser la feuille par séchage au point de la rendre inexploitable. De manière préférée, en termes de tenue mécanique, la feuille de tabac est munie d'un filet de gomme de poids linéaire compris entre 80 et 100 mg/m à l'état sec, avec un effet de tenue et de facilité de mise en œuvre particulièrement surprenant entre 90 et 95 mg/m à l'état sec. La masse à l'état sec signifie la masse de colle après séchage, ou masse d'extrait sec de la colle.Starting from this situation, the technicians in the field of reconstituted tobacco leaves did not seek to increase the quantity of glue from the net, such an increase, even a very slight one, being only supposed to have disadvantages. The inventors have been able to observe that, surprisingly, beyond a linear mass of the thread of glue in the dry state of approximately 70 mg / m 2, the latter exhibits particularly effective adhesion properties, and that it is possible beyond such an amount of glue to produce a dry net without weakening the sheet by drying to the point of rendering it unusable. Preferably, in terms of mechanical strength, the tobacco leaf is provided with a gum net of linear weight of between 80 and 100 mg / m in the dry state, with a holding effect and ease of implementation. particularly surprising work between 90 and 95 mg / m in the dry state. The dry mass means the mass of glue after drying, or mass of dry glue.
Pour produire un séchage satisfaisant d'un tel filet en évitant l'effet de fragilisation constaté jusqu'à présent, on réalise le séchage du filet dans un four muni de rampes de pulvérisation d'eau déminéralisée à l'intérieur de celui-ci. Dans le mode de réalisation décrit ici, le filet de colle est déposé juste avant l'entrée au four de la feuille de tabac reconstitué.To produce a satisfactory drying of such a net while avoiding the embrittlement effect observed up to now, the drying of the net is carried out in an oven provided with booms for spraying demineralized water inside it. In the embodiment described here, the glue thread is deposited just before the reconstituted tobacco leaf enters the oven.
Le four est ici un four convectif muni de moyens d'entraînement des feuilles qui le traversent. Le four présente une longueur d'environ 10 à 15 m. Il est muni d'une rampe de pulvérisation en entrée et d'une rampe disposée sensiblement au milieu du four.The oven here is a convective oven provided with means for driving the sheets which pass through it. The oven has a length of around 10 to 15 m. It is fitted with a sprayer boom at the inlet and a boom arranged substantially in the middle of the oven.
Ces rampes de pulvérisation permettent de tenir une humidité suffisante de la feuille pendant l'ensemble de l'opération de gommage et en particulier pendant le séchage. Ainsi, pendant l'ensemble des opérations, et en particulier pendant le traitement au four, la feuille est maintenue à une humidité comprise entre 12 et 14%.These spray bars make it possible to hold sufficient humidity of the sheet during the entire exfoliation operation and in particular during drying. Thus, during all of the operations, and in particular during the oven treatment, the sheet is kept at a humidity of between 12 and 14%.
Avec un tel maintien de l'humidité dans cette gamme, la feuille gommée présente en sortie du four une humidité d'environ 8 à 10%. Ces conditions d'humidité ont été identifiées comme optimales pour permettre une manipulation ultérieure de la feuille sans perte excessive de feuilles de tabac due à d'éventuelles cassures.With such maintenance of humidity in this range, the gummed sheet has a humidity of about 8 to 10% at the outlet of the oven. These humidity conditions have been identified as optimal to allow subsequent handling of the sheet without excessive loss of tobacco leaves due to possible breakage.
De manière plus générale, on veille conformément à l'invention à maintenir une humidité suffisante de la feuille pendant l'opération de gommage, préférentiellement une humidité supérieure à 7%.More generally, care is taken in accordance with the invention to maintain sufficient humidity of the sheet during the gumming operation, preferably a humidity greater than 7%.
On dispose en sortie du four une ou plusieurs rampes d'air comprimé formant des buses focalisées sur les filets de gomme.At the outlet of the oven, there are one or more ramps of compressed air forming nozzles focused on the rubber threads.
Ces aménagements sont particulièrement efficaces pour sécher la gomme sans sécher la feuille et en particulier pour sécher d'éventuels excès de cette gomme.These arrangements are particularly effective for drying the gum without drying the sheet and in particular for drying any excess of this gum.
De manière connue, les fours utilisés pour le séchage de la gomme disposée sur des feuilles de tabac sont maintenus à une température comprise entre 120 et 140° C. De manière habituelle également, le dépôt de la gomme sur la feuille ainsi que le transport pendant le séchage de la feuille dans le four se fait à une vitesse, appelée vitesse de gommage, qui est située entre 60 et 80 m/mn. Les inventeurs ont pu déterminer une température de four particulièrement propice à un séchage efficace de la gomme tout en permettant un maintien de l'humidité de la feuille de tabac dans les gammes précédemment mentionnées.In known manner, the ovens used for drying the gum placed on tobacco leaves are kept at a temperature between 120 and 140 ° C. In the usual way also, the deposition of the gum on the sheet as well as the transport during the drying of the sheet in the oven takes place at a speed, called the gumming speed, which is situated between 60 and 80 m / min. The inventors have been able to determine an oven temperature which is particularly conducive to effective drying of the gum while allowing humidity of the tobacco leaf to be maintained within the ranges mentioned above.
Ainsi, conformément à l'invention, on utilise une température de four qui est choisie entre approximativement 70 et 90°C, et une vitesse de gommage comprise approximativement entre 18 et 20 m/mn. Pour le four de 15 m utilisé ici, cette vitesse de déplacement correspond à un temps optimal de séchage par chauffage d'environ 45 secondes. Plus généralement, le temps idéal de chauffage est compris entre 30 secondes et 1 minute.Thus, in accordance with the invention, an oven temperature is used which is chosen between approximately 70 and 90 ° C, and a gumming speed of approximately between 18 and 20 m / min. For the 15 m oven used here, this speed of movement corresponds to an optimal drying time by heating of approximately 45 seconds. More generally, the ideal heating time is between 30 seconds and 1 minute.
Grâce à ces dispositions, la feuille de tabac gommée obtenue présente en sortie du four une humidité comprise entre 8 et 10% et un filet de gomme parfaitement sec.Thanks to these provisions, the gummed tobacco leaf obtained has, at the outlet of the oven, a humidity of between 8 and 10% and a thread of perfectly dry gum.
Ces conditions sont optimales pour passer à l'opération d'enchevêtrage dans le cas où l'on réalise un distributeur de feuilles enchevêtrées.These conditions are optimal for proceeding to the tangling operation in the case where a distributor of tangled sheets is produced.
Bien entendu, ces conditions ont été décrites en rapport à l'utilisation d'un four convectif, mais on pourra également les adapter à l'utilisation d'un four radiatif. Dans un tel cas, on utilise un four ayant une longueur d'approximativement 2 à 4m.Of course, these conditions have been described in relation to the use of a convective oven, but they can also be adapted to the use of a radiative oven. In such a case, an oven having a length of approximately 2 to 4 m is used.
Dans le présent procédé, la feuille de tabac est stockée à sa sortie du four sur des bobinettes. Puis ces bobinettes sont protégées de l'évaporation par emballage dans un film plastique imperméable ou toute autre enveloppe étanche. De manière préférentielle et conformément à l'invention, on contrôle également l'humidité de la feuille de tabac au cours de l'opération d'enchevêtrage. Pour cela, des rampes de pulvérisation d'eau déminéralisée sont mises en place en entrée d'un dispositif réalisant l'enchevêtrage.In the present method, the tobacco sheet is stored on leaving the oven on bobbins. Then these coils are protected from evaporation by packaging in an impermeable plastic film or any other impermeable envelope. Preferably and in accordance with the invention, the humidity of the tobacco leaf is also controlled during the entangling operation. For this, demineralized water spraying ramps are put in place at the input of a device carrying out the entanglement.
Bien entendu, les dispositions décrites ici ne se limitent pas à la réalisation d'un article à fumer à feuilles enchevêtrées. La feuille de tabac et les procédés décrits ici pourront être dans le cadre de l'invention appliqués la réalisation de tout autre article à fumer. Of course, the arrangements described here are not limited to the production of a smoking article with tangled sheets. The tobacco leaf and the methods described here may be used in the context of the invention for the production of any other smoking article.
