Description
La présente invention concerne le domaine des articles pour fumeurs.The present invention relates to the field of articles for smoking.
Plus précisément, l'invention concerne le domaine de tels articles utilisant au moins une feuille de tabac reconstitué.More specifically, the invention relates to the field of such articles using at least one reconstituted tobacco leaf.
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.It has been proposed in patent application FR-97 15845 of the Applicant, an article allowing a consumer to prepare himself a cigarillo, this article including in particular a set of reconstituted tobacco leaves intertwined to allow automatic distribution by successive traction 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, reconstituted tobacco leaves, called still tobacco leaves, are applied a trickle of glue on one of their borders. Once dried this net of glue, the leaves are entangled in each other.
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.The net of glue allows once the leaf rolled on itself, of stick the border on the roll thus formed. In particular, we use, as that glue, food glues allowing the user to stick the border with his saliva.
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.In the case of sheets coated with a net of food glue, the glue used can be either a cold glue deposited at temperature convection dried, ie a hot glue, for example a natural gum arabic or a hot-applied synthetic glue with radiation drying (infrared type) located at the right of the glue net, or in a convective oven.
Les techniques actuelles de mise en place de tels filets de colle ne sont pas satisfaisantes.Current techniques for setting up such glue nets 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 the gum in such a proportion that the sheet provided with the gum net does not 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. The leaves provided with a net of glue proposed until now make it possible to realize that cigarillos are particularly fragile.
L'invention a pour but principal de proposer une feuille de tabac reconstitué dont le filet de colle gamissant une de ses bordures produise une fixation satisfaisante de cette bordure sur le reste de la feuille.The main purpose of the invention is to propose a tobacco leaf reconstituted whose net of glue gambling one of its edges produces a satisfactory fixation of this border 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 a piece of reconstituted tobacco coated with a net of glue along one of its borders, characterized in that the linear mass of the glue net 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 oeuvre 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 is proposed application of such a net glue on a reconstituted tobacco leaf thanks tobacco leaf retains some elasticity after place the glue net. Indeed, in the case of known processes application of a net of glue, it is used a drying of the net of glue that also produces a drying of the leaf and makes it brittle. This weakening effect is such that the manufacture of a smoking article where this leaf should 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%.A method according to the invention for applying a net of glue is a in which the glue is dried by heating the sheet provided with this net, and in which the moisture of the leaf is maintained during this drying beyond 7%.
Selon une caractéristique avantageuse de l'invention, on propose un procédé utilisant 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.According to an advantageous characteristic of the invention, a process using an oven equipped with means for translating the sheets, these means passing through the oven, and having means for spraying water at the inlet of the furnace and at least one nozzle blowing air which is arranged so as to blow on the net of glue.
D'autres caractéristiques, buts et avantages de la présente invention apparaítront à la lecture de la description détaillée qui va suivre.Other features, purposes and benefits of this 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'accroche particulièrement réduite aux feuilles de tabac. The gums proposed so far for tobacco leaves are substantially the same as those used on cigarette paper classic. However, these gums appeared difficult to use in this specific application, since they only provide Particularly reduced attachment to tobacco leaves.
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.In addition, we usually put a gum net on a tobacco leaf with a linear mass of gum of about 40 to 50 mg / m, such a quantity of glue being considered as a quantity particularly high.
En effet, pour sécher une telle quantité de colle, on doit déjà faire subir aux feuilles un chauffage qui le fragilise particulièrement.Indeed, to dry such a quantity of glue, we must already do to undergo the leaves a 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, reconstituted tobacco leaf is particularly sensitive humidity variations, and in particular, during the exfoliation, the drying of the gum by the heat reduces the moisture of reconstituted tobacco by 14% to approximately 4%, which has the effect of weakening the sheet to such an extent that it is not more practically possible to manipulate it without producing a large number 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 leaf, the first effect is that the gum is only incompletely dried, while the leaf already has a very embarrassing 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'enchevêtrage devient notamment pratiquement impossible.The fact that the gum is dried only incompletely produces unwanted collages when rewinding the sheet, or when subsequent manipulation, this problem being added to the fragility of the leaf. An entanglement operation becomes in particular 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.Starting from this situation, the technicians of the field of leaves of reconstituted tobacco did not seek to increase the amount of glue of the net, such an increase, however slight, being only present disadvantages.
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.The inventors have found that, surprisingly, beyond a linear mass of the adhesive net in the dry state of about 70 mg / m, it has particularly effective adhesion properties, and that it is possible beyond such a quantity of glue to make a dry net without weakening the leaf by drying to the point of making it unusable.
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 oeuvre 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.Preferably, in terms of mechanical strength, the sheet of tobacco is provided with a gum net of linear weight between 80 and 100 mg / m in the dry state, with a holding effect and ease of implementation particularly surprising between 90 and 95 mg / m in the dry state. The mass in the dry state means the mass of glue after drying, or mass dry extract of the 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 avoiding the effect of embrittlement observed so far, the drying of the net is carried out in an oven equipped with demineralised water spray booms inside this one. In the embodiment described here, the net of glue is deposited just before the baking of the reconstituted tobacco leaf.
Le four est ici un four convectif muni de moyens d'entraínement 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 is here a convective oven provided with means of training leaves that cross it. The oven has a length of about 10 to 15 m. It has an inlet spray boom and a ramp disposed 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.These spray bars help hold moisture enough leaf during the entire scrubbing operation and in especially during drying.
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%.Thus, during all operations, and in particular during the baking process, the sheet is kept at a humidity 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%.With such a maintenance of moisture in this range, the sheet gummed present at the outlet of the oven a moisture of about 8 to 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.These moisture conditions have been identified as optimal for allow further handling of the leaf 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, it ensures in accordance with the invention to maintain a sufficient moisture of the leaf during the operation of exfoliation, 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.One or more air ramps are available at the outlet of the oven compressed forming nozzles focused on the gum nets.
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 to dry 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. In known manner, the ovens used for drying the gum placed on tobacco leaves are kept at a temperature between 120 and 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/min.Usually also, the deposit of the rubber on the sheet as well as transport during the drying of the sheet in the oven itself done at a speed, called scrubbing speed, which is between 60 and 80 m / min.
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.The inventors were able to determine a furnace temperature particularly conducive to efficient drying of the gum while allowing a maintenance of the moisture of the tobacco leaf in the ranges previously mentioned.
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/min. 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 speed of scrub approximately between 18 and 20 m / min. For the oven of 15 m used here, this speed of movement corresponds to a time optimal drying by heating about 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 present at the outlet of the oven a humidity between 8 and 10% and a net 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 moving to the operation entanglement in the case where a distributor of sheets is made entangled.
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 convection oven, but we can also adapt them to the use of a radiative furnace. In such a case, an oven having a length of approximately 2 to 4m.
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.In the present process, the tobacco leaf is stored at its output of the oven on bobbins. Then these reels are protected from evaporation by packaging in a waterproof plastic film or any other sealed envelope.
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. Preferably and according to the invention, it controls also the moisture of the tobacco leaf during the operation of interleaving.
Pour cela, des rampes de pulvérisation d'eau déminéralisée sont mises en place en entrée d'un dispositif réalisant l'enchevêtrage.For this, demineralised water spray booms are put in place at the entrance of a device performing entanglement.
Bien entendu, les dispositions décrites ici ne se limitent pas à la réalisation d'un article à fumer à feuilles enchevêtrées.Of course, the provisions described here are not limited to making a smoking article with entangled leaves.
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.The tobacco leaf and the methods described herein may be in the The scope of the invention applies to the production of any other smoking article.
