Description

La présente invention concerne un procédé de fabrication d'étiquettes multi-volets, qui peuvent être autocollantes.The present invention relates to a method for manufacturing multi-flap labels, which can be self-adhesive.

On a déjà réalisé des étiquettes de ce type comprenant un feuillet étiquette ayant une couche adhésive éventuellement protégée avant sa dépose par un support anti-adhésif. Sur l'étiquette, sont rapportés un ou plusieurs volets supplémentaires dont un feuillet de couverture, réalisés par plusieurs feuillets ou par repliement d'un seul plus grand feuillet. Le feuillet de couverture et le feuillet étiquette étant plus grands sur au moins l'un des côtés afin de constituer une marge où ils sont collés l'un à l'autre de manière à maintenir les feuillets intérieurs.Labels of this type have already been produced comprising a label sheet having an adhesive layer which may be protected before being deposited by a support anti adhesive. On the label, one or more additional flaps are reported including a cover sheet, produced by several sheets or by folding of a single larger sheet. The cover sheet and the label sheet being larger on at least one of the sides in order to constitute a margin where they are glued to each other so as to maintain the inner sheets.

La fabrication d'une telle étiquette nécessite une étape d'application d'une couche de colle sur au moins sur une marge de l'étiquette entre le feuillet étiquette et le feuillet de couverture.The manufacture of such a label requires a step of applying a layer glue on at least one margin of the label between the label sheet and the cover sheet.

Par ailleurs, si l'on souhaite que les volets soient maintenus en position repliée, il est également nécessaire de prévoir au moins une étape supplémentaire d'application d'une bande de colle sur une autre marge de l'étiquette.Furthermore, if it is desired that the flaps be kept in the folded position, it it is also necessary to plan at least one additional step applying a strip of glue on another margin of the label.

Il s'avère que les traitements d'encollage sont plutôt délicats à réaliser et nécessitent des équipements particuliers coûteux. It turns out that the sizing treatments are rather delicate to perform and require expensive special equipment.

Par ailleurs, pour pouvoir ouvrir l'étiquette et accéder aux différents volets de l'étiquette, la colle utilisée doit être détachable, ou bien il faut prévoir en outre de réaliser une ligne de perforations que l'on peut déchirer pour ouvrir l'étiquette, cette ouverture étant alors définitive.In addition, to be able to open the label and access the different components of the label, the adhesive used must be removable, or else provision must be made make a line of perforations that you can tear to open the label, this opening then being final.

Il s'avère que ces différentes solutions sont complexes à mettre en oeuvre, et font intervenir des traitements d'encollage qui sont plutôt délicats à réaliser, qui nécessitent des équipements coûteux, et entraínent des cadences de production plus faibles. Il en résulte des coûts de fabrication relativement élevés.It turns out that these different solutions are complex to implement, and involve sizing treatments which are rather delicate to carry out, which require expensive equipment, and cause rates of lower production. This results in relatively low manufacturing costs high.

Par le document WO 96/27177, sur lequel est basé le préambule de la revendication 1, on a également proposé un procédé pour la fabrication d'étiquettes comportant plusieurs volets, ce procédé comprenant la dépose sur un feuillet de base, d'au moins un feuillet intermédiaire moins large que le feuillet de base, de manière à laisser au moins deux marges opposées du feuillet de base, non recouvertes par le feuillet intermédiaire et, l'application d'un feuillet de couverture revêtu d'une couche adhésive protégée par une feuille de protection de manière à ce que cette couche adhésive n'adhère pas au feuillet mais seulement au moins partiellement sur lesdites marges.WO 96/27177, on which the preamble of claim 1 is based, has also been proposed a method for the manufacture of labels comprising several flaps, this process comprising the deposit at least one narrower intermediate sheet on a basic sheet than the base sheet, so as to leave at least two opposite margins of the basic sheet, not covered by the intermediate sheet and, the application a cover sheet coated with an adhesive layer protected by a protective sheet so that this adhesive layer does not adhere to the sheet but only at least partially on said margins.

L'inconvénient de cette solution est d'engendrer des surépaisseurs et de provoquer des défauts d'étanchéité lorsque la feuille de protection comprend une languette traversant une marge pour faciliter l'ouverture.The drawback of this solution is to generate extra thicknesses and cause leaks when the protective sheet includes a tab crossing a margin to facilitate opening.

Pour supprimer cet inconvénient, le procédé selon l'invention est caractérisé en ce que :

  • la face adhésive du feuillet de couverture est appliquée sur le feuillet intermédiaire,
  • la neutralisation partielle de l'adhésif sur la marge du feuillet de couverture, est obtenue en appliquant une matière anti-adhésive sur la marge correspondante du feuillet de base.
To eliminate this drawback, the method according to the invention is characterized in that:
  • the adhesive side of the cover sheet is applied to the intermediate sheet,
  • partial neutralization of the adhesive on the margin of the cover sheet is obtained by applying a non-stick material to the corresponding margin of the base sheet.

Grâce à ces dispositions, le feuillet intermédiaire est fixé au feuillet de base au moyen du feuillet de couverture adhésif le long de deux bords opposés. Le procédé selon l'invention permet ainsi d'obtenir une étiquette comportant au moins trois faces imprimables, à savoir la face supérieure du feuillet de base, la face inférieure du feuillet intermédiaire et la face supérieure de l'étiquette ainsi obtenue, sans faire intervenir d'étape d'encollage.Thanks to these provisions, the intermediate sheet is fixed to the basic sheet at using the adhesive cover sheet along two opposite edges. The process according to the invention thus makes it possible to obtain a label comprising at least three printable sides, namely the upper side of the basic sheet, the underside of the intermediate sheet and the top of the label thus obtained, without involving a gluing step.

Pour ouvrir l'étiquette, il suffit de soulever la marge du feuillet de couverture partiellement neutralisée, l'autre marge du feuillet de couverture qui reste collée au feuillet de base constituant une marge de reliure de l'étiquette multi-volets ainsi réalisée.To open the label, simply lift the margin of the cover sheet partially neutralized, the other margin of the remaining cover sheet glued to the basic sheet constituting a binding margin of the multi-fold label thus carried out.

Comme la colle de la marge du feuillet de couverture que l'on soulève est partiellement neutralisée, on peut la recoller sur le feuillet de base pour refermer l'étiquette.
Avantageusement, le feuillet de base est un feuillet étiquette préfabriqué, muni d'une couche d'adhésif autocollant, recouverte par un support de protection anti-adhésif que l'on peut retirer pour coller l'étiquette sur un autre support.
Il convient de noter à ce sujet que la qualité du maintien à l'état fermé ainsi obtenu de l'étiquette ne dépend pas de la nature du matériau sur lequel est collée l'étiquette.As the glue of the margin of the cover sheet that is lifted is partially neutralized, it can be stuck on the base sheet to close the label.
Advantageously, the basic sheet is a prefabricated label sheet, provided with a layer of self-adhesive adhesive, covered by a non-stick protective support which can be removed to stick the label on another support.
In this regard, it should be noted that the quality of keeping the label thus obtained in a closed state does not depend on the nature of the material on which the label is affixed.

Selon une particularité de l'invention, le feuillet intermédiaire est un feuillet multi-volets à plusieurs volets repliés les uns sur les autres ou un livret, de manière à obtenir une surface imprimable encore plus importante.According to a feature of the invention, the intermediate sheet is a sheet multi-part with several parts folded over each other or a booklet, so as to obtain an even larger printable surface.

Selon une autre particularité de l'invention, la neutralisation partielle de l'adhésif de la marge du feuillet de couverture est obtenue en appliquant une matière anti-adhésive sur la marge correspondante du feuillet de base.
Il s'avère qu'une telle matière anti-adhésive, par exemple un verni, peut être appliquée facilement, notamment par une technique d'impression classique.
De cette manière, l'ouverture de l'étiquette peut être effectuée plusieurs fois sans dommage notable de la couche d'adhésif sur les marges décollées du feuillet de couverture.According to another feature of the invention, the partial neutralization of the adhesive of the margin of the cover sheet is obtained by applying a non-stick material to the corresponding margin of the base sheet.
It turns out that such a non-stick material, for example a varnish, can be applied easily, in particular by a conventional printing technique.
In this way, the opening of the label can be carried out several times without significant damage to the layer of adhesive on the unglued margins of the cover sheet.

Alternativement, le feuillet de couverture est un feuillet étiquette préfabriqué, muni d'une couche d'adhésif autocollant, recouverte par un support de protection anti-adhésif, la neutralisation partielle de l'adhésif de la marge du feuillet de couverture étant obtenue en laissant une bande de ce support de protection anti-adhésif, cette bande étant située à l'aplomb du bord correspondant du feuillet intermédiaire et recouvrant une partie de la marge du feuillet de couverture, à une certaine distance du bord du feuillet de couverture.Alternatively, the cover sheet is a prefabricated label sheet, with a layer of self-adhesive adhesive, covered by a protective support anti-adhesive, partial neutralization of the adhesive from the margin of the cover being obtained by leaving a strip of this non-stick protective support, this strip being located directly above the corresponding edge of the sheet intermediate and covering part of the margin of the cover sheet, at a some distance from the edge of the cover sheet.

Une telle étiquette peut s'ouvrir en arrachant la bande. Alternativement, on peut prévoir une ligne de prédécoupe réalisée dans le feuillet de couverture le long du bord de la bande anti-adhésive, du côté du bord du feuillet de couverture. De cette manière, si l'on tire sur cette bande, le feuillet de couverture se déchire uniquement le long de la ligne de prédécoupe, la bande restant collée à la partie du feuillet de couverture que l'on soulève. L'étiquette peut ensuite être refermée en enlevant au moins partiellement la bande, ce qui dégage une portion adhésive du feuillet de couverture. A cet effet, on peut prévoir également d'enduire la zone du feuillet de base en regard de la bande de matière anti-adhésive, ou de réaliser des découpes transversales dans la bande, de manière à permettre le retrait d'une partie de la bande, et ainsi de dégager une partie de la surface autocollante de la bande, à chaque fois que l'on désire refermer l'étiquette. Cette étiquette peut ainsi être refermée plusieurs fois.Such a label can be opened by tearing off the strip. Alternatively, we can provide a pre-cut line made in the cover sheet along the edge of the non-stick strip, on the side of the edge of the cover sheet. Of this way, if we pull on this strip, the cover sheet tears only along the pre-cut line, the strip remaining stuck to the part of the cover sheet that you lift. The label can then be closed by at least partially removing the strip, which releases an adhesive portion of the cover sheet. For this purpose, provision can also be made to coat the area of the base sheet opposite the strip of non-stick material, or transverse cuts in the strip, so as to allow the removal of a part of the strip, and thus to release part of the self-adhesive surface of the tape, whenever you want to close the label. This label can thus be closed several times.

On peut prévoir que le feuillet intermédiaire présente des dimensions inférieures à celles du feuillet de base de manière à laisser non recouvertes toutes les marges de celui-ci. Dans ce cas, l'adhésif sur les marges du feuillet de couverture est partiellement neutralisé, sauf sur une marge servant de reliure du feuillet intermédiaire.We can predict that the intermediate sheet has smaller dimensions to those in the basic sheet so as to leave all margins uncovered of it. In this case, the adhesive on the margins of the cover sheet is partially neutralized, except on a margin serving as binding of the sheet intermediate.

Selon une autre particularité de l'invention, le feuillet de couverture est transparent Dans ce cas, toutes les faces du feuillet intermédiaire peuvent être imprimées. On peut ainsi limiter les éléments à imprimer de l'étiquette à un seul feuillet, éventuellement à plusieurs volets repliés les uns sur les autres, ce qui simplifie considérablement la fabrication des étiquettes imprimées comme les étiquettes publicitaires.According to another feature of the invention, the cover sheet is transparent In this case, all sides of the intermediate sheet can be printed. It is thus possible to limit the elements to be printed on the label to a single sheet, possibly with several flaps folded over each other, which considerably simplifies the production of printed labels such as advertising labels.

Selon une autre particularité de l'invention, le feuillet de base est muni d'une ligne de découpe le long de la marge de reliure, de préférence légèrement en dessous du feuillet intermédiaire. De cette manière, le feuillet intermédiaire peut facilement être séparé du feuillet de base et l'ensemble de l'étiquette peut être collée sur une surface cylindrique sans former de bosses ou plissements. A cet effet, on peut prévoir avantageusement une double ligne de découpe, pour permettre le retrait d'une bande dans le feuillet de base de manière à absorber ces bosses ou plissements, tout en évitant le recouvrement des bords de la ligne de découpe dans le feuillet de base.According to another feature of the invention, the basic sheet is provided with a cutting line along the binding margin, preferably slightly in below the intermediate sheet. In this way, the intermediate sheet can easily be separated from the base sheet and the whole label can be glued to a cylindrical surface without forming bumps or wrinkles. In this Indeed, one can advantageously provide a double cutting line, for allow the removal of a strip in the base sheet so as to absorb these bumps or wrinkles, while avoiding overlapping the edges of the line of cut out from the basic sheet.

Il s'avère que ce procédé est parfaitement adapté à la fabrication en série d'étiquettes multi-volets.It turns out that this process is perfectly suited to mass production of multi-fold labels.

L'invention concerne également une étiquette multi-volets obtenue par ce procédé.The invention also relates to a multi-part label obtained by this process.

Un mode de réalisation d'une étiquette obtenue par le procédé selon l'invention sera décrit ci-après, à titre d'exemple non limitatif, avec référence aux dessins annexés dans lesquels :

    • la disposition sur le feuillet de base 1 d'au moins un feuillet intermédiaire 5, le feuillet intermédiaire ayant une largeur inférieure à celle du feuillet de base 1 de manière à laisser non recouvertes au moins deux marges latérales opposées 3 et 4 du feuillet de base,
    • la neutralisation partielle préalable de l'adhésif de la marge 13 du feuillet de couverture 6 venant se coller sur l'une 4 des deux marges 3, 4 non recouvertes du feuillet de base 1, et
    • le collage du feuillet de couverture 6 adhésif sur les marges 3, 4 du feuillet de base 1 et sur le feuillet intermédiaire 5, la marge 3 formant une reliure.
    It is manufactured by the following operations:
    • the provision on the base sheet 1 of at least one intermediate sheet 5, the intermediate sheet having a width less than that of the base sheet 1 so as to leave uncovered at least two opposite lateral margins 3 and 4 of the base sheet ,
    • the partial partial neutralization of the adhesive of the margin 13 of the cover sheet 6 coming to be stuck on one 4 of the two margins 3, 4 not covered with the base sheet 1, and
    • gluing the adhesive cover sheet 6 to the margins 3, 4 of the base sheet 1 and to the intermediate sheet 5, the margin 3 forming a binding.

    Le feuillet intermédiaire 5 peut être réalisé à partir d'une feuille repliée sur elle-même pour former plusieurs volets. Il peut aussi avoir la forme d'un livret à plusieurs pages simples ou doubles assemblées par une reliure.The intermediate sheet 5 can be produced from a sheet folded over on itself to form several strands. It can also take the form of a booklet several single or double pages joined together by a binding.

    Selon un premier mode de réalisation préféré de l'étiquette selon l'invention, la neutralisation partielle de l'adhésif sur la marge 13 du feuillet de couverture 6 est obtenue en appliquant sur la marge 4 du feuillet de base 1 une matière 11 anti-adhésive, telle qu'un vernis. De cette manière l'adhésif du feuillet de couverture 6 adhère à la marge 4 du feuillet de base, et peut à la fois être décollé sans notable détérioration, et recollé.According to a first preferred embodiment of the label according to the invention, the partial neutralization of the adhesive on the margin 13 of the cover sheet 6 is obtained by applying a non-stick material 11 to the margin 4 of the basic sheet 1, such as a varnish. In this way the adhesive of the cover sheet 6 adheres to margin 4 of the base sheet, and can both be peeled off without noticeable deterioration, and glued.

    Le feuillet intermédiaire 5 peut avoir la même longueur que celle du feuillet de base 1 ou du feuillet de couverture, comme cela est représenté sur la figure 2.The intermediate sheet 5 can have the same length as that of the base 1 or cover sheet, as shown in Figure 2.

    Cependant, pour améliorer encore la tenue à la fermeture de l'étiquette, le feuillet intermédiaire 5' peut avoir une longueur inférieure à celle du feuillet de base 1 comme représenté sur la figure 3, de manière à ce que des marges supérieures et inférieures 4' du feuillet de base ne soient pas recouvertes par le feuillet intermédiaire. Dans ce cas, la matière anti-adhésive 11 doit être également appliquée sur les marges 4, 4' du feuillet de base 1, à l'exception de l'ensemble de la marge de reliure 3.
    De cette manière, pour ouvrir l'étiquette, il est facile de décoller l'ensemble des marges 13, 13' du feuillet de couverture 6, collées sur les marges 4, 4' enduites de matière anti-adhésive, et de les recoller ensuite pour refermer l'étiquette.    However, to further improve the resistance to closure of the label, the intermediate sheet 5 ′ may have a length less than that of the base sheet 1 as shown in FIG. 3, so that upper and lower margins 4 'of the base sheet are not covered by the intermediate sheet. In this case, the non-stick material 11 must also be applied to the margins 4, 4 ′ of the base sheet 1, with the exception of the whole of the binding margin 3.
    In this way, to open the label, it is easy to peel off all of the margins 13, 13 'of the cover sheet 6, glued to the margins 4, 4' coated with non-stick material, and then to glue them again to close the label.

    Une partie 8, de préférence dans un angle de la marge 13 du feuillet de couverture 6, peut servir d'onglet destiné à faciliter le décollement de la marge 4 et ainsi l'ouverture de l'étiquette et l'accès au feuillet intermédiaire 5, 5'. A cet effet, la colle recouvrant la face inférieure de cette partie 8 peut être totalement neutralisée, par exemple en la retirant.A part 8, preferably in an angle of the margin 13 of the sheet of cover 6, can be used as a tab intended to facilitate the separation of the margin 4 and thus the opening of the label and access to the intermediate sheet 5, 5 '. In this Indeed, the glue covering the underside of this part 8 can be completely neutralized, for example by removing it.

    Sur les figures 4 à 8, l'adhésif de la marge 13 du feuillet de couverture 6 est partiellement neutralisée par une bande 7 recouvrant l'ensemble de cette marge 13 à l'exception d'une bande étroite 9 le long du bord adjacent du feuillet de couverture. Cette bande 7 peut avantageusement provenir d'une feuille support anti-adhésive qui protégeait la face adhésive du feuillet de couverture avant que celui-ci soit posé sur l'étiquette, le feuillet de couverture provenant d'une étiquette autocollante préfabriquée.In FIGS. 4 to 8, the adhesive of the margin 13 of the cover sheet 6 is partially neutralized by a strip 7 covering the entire margin 13 with the exception of a narrow strip 9 along the adjacent edge of the blanket. This strip 7 can advantageously come from a support sheet non-stick which protected the adhesive side of the cover sheet before this is placed on the label, the cover sheet coming from a prefabricated self-adhesive label.

    On peut avantageusement prévoir que cette bande soit disposée légèrement au dessus du feuillet intermédiaire 5. De cette manière, lorsque l'étiquette est collée sur une surface cylindrique, on évite que les volets du feuillet intermédiaire 5 soient en contact avec la surface encollée du feuillet de couverture 6.It can advantageously be provided for this strip to be arranged slightly at the above the intermediate sheet 5. In this way, when the label is stuck on a cylindrical surface, the flaps of the intermediate sheet 5 are avoided are in contact with the glued surface of the cover sheet 6.

    Cette bande 7, avec le feuillet de couverture, peut comprendre un prolongement s'étendant au-delà du bord du feuillet de base 1, pour former un onglet 12 qui facilite la préhension de la bande 7 en vue de son décollement (figure 7).This strip 7, with the cover sheet, may include an extension extending beyond the edge of the base sheet 1, to form a tab 12 which facilitates the gripping of the strip 7 with a view to detaching it (FIG. 7).

    Une telle étiquette peut être ouverte de deux manières, soit en arrachant la bande 7 située à l'aplomb du bord du feuillet intermédiaire 5, soit en prévoyant une ligne de prédécoupe, réalisée dans le feuillet de couverture 6 le long du bord extérieur 10 de la bande 7 (du côté de la marge 9), comme représenté sur les figures 7 et 8. Dans ce dernier cas, après ouverture de l'étiquette, la marge 9 du feuillet de couverture reste collée sur le feuillet de base 1, tandis que la bande 7 reste collée sur la partie du feuillet de couverture collée au volet supérieur du feuillet intermédiaire 5.
    La ligne de prédécoupe peut être également être réalisée de manière à perforer à la fois le feuillet de couverture 6 et la bande 7. Dans ce cas, après ouverture de l'étiquette, seule une partie de la bande 7 reste collée au feuillet de couverture 6, tandis que l'autre partie de cette bande reste maintenue au feuillet de base 1.    Such a label can be opened in two ways, either by tearing off the strip 7 situated directly above the edge of the intermediate sheet 5, or by providing a precut line, produced in the cover sheet 6 along the outer edge 10 of the strip 7 (on the side of the margin 9), as shown in FIGS. 7 and 8. In the latter case, after opening the label, the margin 9 of the cover sheet remains stuck on the base sheet 1, while that the strip 7 remains stuck on the part of the cover sheet stuck to the upper flap of the intermediate sheet 5.
    The precut line can also be made so as to perforate both the cover sheet 6 and the strip 7. In this case, after opening the label, only part of the strip 7 remains stuck to the cover sheet. 6, while the other part of this strip remains maintained on the basic sheet 1.

    Alternativement à l'onglet 12, on peut prévoir, comme représenté sur la figure 8, un onglet 12' de forme sensiblement triangulaire réalisé à la fois dans le feuillet de couverture 6 et le feuillet intermédiaire 5 (dans toutes les épaisseurs de ce feuillet), et éventuellement dans le feuillet de base 1, cet onglet ayant un bord situé à l'aplomb du bord extérieur 10 de la bande 7. Grâce à son épaisseur, un tel onglet peut facilement être saisi, ce qui facilite l'ouverture de l'étiquette.As an alternative to tab 12, one can provide, as shown in FIG. 8, a tab 12 ′ of substantially triangular shape produced both in the sheet cover 6 and intermediate sheet 5 (in all thicknesses of this sheet), and possibly in the base sheet 1, this tab having an edge located directly above the outer edge 10 of the strip 7. Thanks to its thickness, such a tab can easily be entered, making it easy to open the label.

    Pour refermer l'étiquette, la bande 7 peut être totalement ou partiellement retirée ce qui dégage une partie de la surface adhésive du feuillet de couverture, qui peut être collée sur la face supérieure du feuillet de base 1.
    Pour autoriser plusieurs manipulations d'ouverture et de fermeture de l'étiquette, on peut prévoir d'enduire d'une matière anti-adhésive, la zone de la face supérieure du feuillet de base, située en regard de la bande 7. Alternativement, on peut prévoir dans la bande 7 plusieurs lignes de découpes transversales, de manière à faciliter un retrait partiel de la bande à chaque fois que l'on souhaite refermer l'étiquette.    To close the label, the strip 7 can be totally or partially removed, which releases part of the adhesive surface of the cover sheet, which can be glued to the upper face of the base sheet 1.
    To allow several manipulations of opening and closing of the label, provision may be made to coat with a non-stick material, the area of the upper face of the base sheet, located opposite the strip 7. Alternatively, it is possible to provide in the strip 7 several lines of transverse cuts, so as to facilitate a partial withdrawal of the strip each time it is desired to close the label.

    Le feuillet de couverture 6, ainsi que la bande 7 sont avantageusement réalisés en une matière transparente. Dans ce cas, seul le feuillet intermédiaire 5 peut être préalablement imprimé sur l'ensemble de ses faces, et éventuellement le feuillet de base 1.The cover sheet 6, as well as the strip 7 are advantageously made in a transparent material. In this case, only the intermediate sheet 5 can be previously printed on all of its faces, and possibly the leaflet basic 1.

    Bien entendu, le principe de la bande anti-adhésive 7, tel que décrit en référence aux figures 4 à 8, peut être appliqué à une étiquette analogue à celle représentée sur la figure 3. Il suffit alors de prévoir une bande anti-adhésive qui s'étend à la fois le long de la marge 13 et des marges 13' du feuillet de couverture 6. Dans ce cas, le feuillet de couverture 6 peut comporter une ligne de prédécoupe à l'aplomb du bord extérieur de la bande.Of course, the principle of the non-stick strip 7, as described with reference in Figures 4 to 8, can be applied to a label similar to that shown in FIG. 3. It then suffices to provide a non-stick strip which extends to the times along the margin 13 and the margins 13 'of the cover sheet 6. In this case, the cover sheet 6 may include a pre-cut line at plumb with the outer edge of the strip.

    Selon une autre particularité de l'invention, le feuillet de base comprend deux couches liées entre elles par un adhésif dit "fugitif' ou "pelable" qui présente la particularité de permettre la séparation définitive des deux couches sans détérioration de celles-ci et sans laisser de trace perceptible de colle. De cette manière, le feuillet intermédiaire 5, éventuellement multi-volets peut être détaché du produit sur lequel est collée l'étiquette selon l'invention.
    On peut prévoir que la couche inférieure du feuillet de base 1 est transparente, de manière à être peu visible sur le produit lorsque les autres couches de l'étiquette ont été retirées.
    Un tel adhésif "fugitif" peut être appliqué par une simple technique d'impression, en remplaçant l'encre par l'adhésif "fugitif" sous forme fluide.    According to another feature of the invention, the basic sheet comprises two layers linked together by a so-called "fugitive" or "peelable" adhesive which has the particularity of allowing the final separation of the two layers without deterioration thereof and without leave a perceptible trace of glue In this way, the intermediate sheet 5, possibly multi-flaps can be detached from the product on which the label according to the invention is stuck.
    Provision may be made for the lower layer of the base sheet 1 to be transparent, so as to be barely visible on the product when the other layers of the label have been removed.
    Such a "fugitive" adhesive can be applied by a simple printing technique, replacing the ink with the "fugitive" adhesive in fluid form.

    Selon une autre particularité de l'invention, le feuillet de base 1 comprend une ligne de découpe 14 le long de la marge de reliure 3, éventuellement légèrement en dessous du feuillet intermédiaire 5, 5' (figures 1 à 8). Cette ligne de découpe permet de séparer l'ensemble constitué par le feuillet de couverture 6, le feuillet intermédiaire 5 et la marge de reliure 3 du feuillet de base 1, du reste du feuillet de base, simplement en décollant la marge 3 du feuillet de base du support anti-adhésif 2 ou de l'objet sur lequel l'étiquette est collée.
    Elle permet également d'absorber les plissements qui se forment lorsque l'étiquette est collée sur une surface cylindrique, du fait que l'étiquette comporte plusieurs épaisseurs. Dans ce cas, les plissements sont absorbés par un léger recouvrement des bords de la ligne de découpe 14.    According to another feature of the invention, the basic sheet 1 comprises a cutting line 14 along the binding margin 3, possibly slightly below the intermediate sheet 5, 5 '(Figures 1 to 8). This cutting line makes it possible to separate the assembly constituted by the cover sheet 6, the intermediate sheet 5 and the binding margin 3 of the base sheet 1, from the rest of the base sheet, simply by peeling off the margin 3 of the sheet of base of the non-stick support 2 or of the object on which the label is stuck.
    It also makes it possible to absorb the creases which form when the label is stuck on a cylindrical surface, because the label has several thicknesses. In this case, the creases are absorbed by a slight overlap of the edges of the cutting line 14.

    Pour éviter ce recouvrement, on peut prévoir de réaliser deux lignes de découpes parallèles et légèrement espacées de manière à délimiter une bande que l'on retire, la largeur de cette bande correspondant à la largeur du recouvrement observé dans le cas d'une seule ligne de découpe 14 et étant fonction de la courbure de la surface cylindrique où doit être collée l'étiquette.To avoid this overlap, provision can be made for two cutting lines parallel and slightly spaced so as to delimit a band which one remove, the width of this strip corresponding to the width of the overlap observed in the case of a single cutting line 14 and being a function of the curvature of the cylindrical surface where the label is to be stuck.

    Il est à noter que cette ligne de découpe 14 n'est pas nécessairement parallèle à la marge 3.
    On peut également remarquer que dans les modes de réalisation avec la bande 7 (figures 4 à 8), aucune partie adhésive n'est dégagée lorsque le feuillet de couverture 6, le feuillet intermédiaire 5 et la marge 3 sont séparés du reste de l'étiquette, même dans le cas de la figure 3 où l'ensemble de la zone de bord du feuillet de couverture 6 est collé sur le feuillet de base 1.
    Avantageusement, on peut prévoir que le feuillet de base 1 comporte les mêmes inscriptions (ou des inscriptions similaires) que le feuillet de couverture 6, ou le volet supérieur du feuillet intermédiaire 5, si le feuillet de couverture est transparent. De cette manière, l'étiquette qui reste collée sur son support présente toujours des informations identiques ou similaires, que le feuillet intermédiaire 5 avec le feuillet de couverture 6 soit ou non séparé du feuillet de base 1, grâce à la ligne de découpe 14.    It should be noted that this cutting line 14 is not necessarily parallel to the margin 3.
    It can also be noted that in the embodiments with the strip 7 (FIGS. 4 to 8), no adhesive part is released when the cover sheet 6, the intermediate sheet 5 and the margin 3 are separated from the rest of the label, even in the case of FIG. 3 where the entire edge area of the cover sheet 6 is glued to the base sheet 1.
    Advantageously, provision can be made for the basic sheet 1 to have the same inscriptions (or similar inscriptions) as the cover sheet 6, or the upper flap of the intermediate sheet 5, if the cover sheet is transparent. In this way, the label which remains stuck on its support always presents identical or similar information, whether or not the intermediate sheet 5 with the cover sheet 6 is separated from the base sheet 1, by virtue of the cutting line 14.

    L'étiquette précédemment décrite est parfaitement adaptée à une fabrication en série comme illustré sur les figures 8 et 9. Sur la figure 8, cette fabrication met en oeuvre :

    • un poste 21 de distribution d'une bande de base 33, qui peut être autocollante et protégée par une bande support 34 revêtue d'une matière anti-adhésive,
    • un poste de distribution et de dépose 25 de feuillets intermédiaires simples ou multi-volets 5 qui peuvent être préalablement imprimés, sur la bande de base 33,
    • un poste 37 d'enduction de zones de la bande de base 33, situées à l'aplomb des feuillets 5, avec une matière anti-adhésive,
    • un poste de distribution 22 d'une bande de couverture adhésive 27,
    • un poste de compression 36 pour coller la bande de couverture 35 sur l'ensemble de la bande de base 33 et des feuillets 5,
    • un poste de découpe 29 de la bande de couverture 35 et de la bande de base 33 le long des bords des étiquettes à réaliser, afin de former une série d'étiquettes multi-volets, et
    • un poste d'extraction 30 pour enlever de la bande support 34, les parties découpées de la bande de couverture 35 et de la bande de base 33, entre les étiquettes ainsi réalisées, la bande support 34 sur laquelle sont réalisées les étiquettes étant enroulée par un poste 32, tandis que les parties extraites sont enroulées par un poste 31.
    The previously described label is perfectly suited to mass production as illustrated in FIGS. 8 and 9. In FIG. 8, this manufacture implements:
    • a station 21 for dispensing a base strip 33, which can be self-adhesive and protected by a support strip 34 coated with a non-stick material,
    • a station for distributing and depositing 25 single or multi-part intermediate sheets 5 which can be previously printed, on the base strip 33,
    • a station 37 for coating areas of the base strip 33, located directly above the sheets 5, with a non-stick material,
    • a distribution station 22 of an adhesive cover strip 27,
    • a compression station 36 for gluing the cover strip 35 to the entire base strip 33 and sheets 5,
    • a station 29 for cutting the cover strip 35 and the base strip 33 along the edges of the labels to be produced, in order to form a series of multi-fold labels, and
    • an extraction station 30 for removing from the support strip 34, the cut parts of the cover strip 35 and of the base strip 33, between the labels thus produced, the support strip 34 on which the labels are produced being wound by a station 32, while the extracted parts are wound up by a station 31.

    Pour réaliser la ligne de découpe 14, simple ou double, il faut prévoir en outre un poste de découpe situé en amont du poste de dépose 25 des feuillets intermédiaires. Ce poste de découpe doit être réglé de manière à ne découper que la bande de base 33 et non la bande support 34.To make the cutting line 14, single or double, it is also necessary to provide a cutting station located upstream of the station for depositing 25 sheets intermediate. This cutting station must be set so that it only cuts the base band 33 and not the support band 34.

    Alternativement, sur la figure 9, la bande de couverture adhésive est revêtue d'une bande de protection 26 anti-adhésive, le dispositif de fabrication comprenant en outre :

    • un poste de découpe de bandes 7 dans la bande de protection 26 anti-adhésive,
    • un poste d'extraction 28 de la bande de protection 26, à l'exception des bandes découpées 7, suivi d'un poste d'enroulement 23 de la bande 26.
    Alternatively, in FIG. 9, the adhesive cover strip is coated with a non-stick protective strip 26, the manufacturing device further comprising:
    • a strip cutting station 7 in the non-stick protective strip 26,
    • an extraction station 28 for the protective strip 26, with the exception of the cut strips 7, followed by a winding station 23 for the strip 26.

    Bien entendu, la dépose des feuillets 5 peut aussi être effectuée sur la bande de couverture 27, avant le collage de la bande de base 33 sur la bande de couverture. Of course, the deposition of the sheets 5 can also be carried out on the strip of cover 27, before the base strip 33 is bonded to the cover strip.

    Ce dispositif peut également comprendre un poste 37 d'enduction comme montré sur la figure 8, et un poste de prédécoupe 38 pour réaliser une ligne de prédécoupe à l'aplomb du bord des bandes 7 de support de protection 26 laissées sur la bande de couverture 27, pour faciliter la première ouverture des étiquettes ainsi réalisées.This device can also include a coating station 37 as shown in FIG. 8, and a precut station 38 for making a line of pre-cut directly below the edge of the protective support strips 7 left 26 on the cover strip 27, to facilitate the first opening of the labels thus carried out.

    Comme mentionnée précédemment la bande de base 33 peut être revêtue d'une couche supplémentaire liée à la bande de base par une couche d'adhésif "fugitif'. Dans ce cas, il suffit cela de prévoir, en amont du poste de dépose 25 des feuillets intermédiaires 5, un poste d'impression qui applique l'adhésif "fugitif" sur la face supérieure de la bande de base, et un poste d'application d'une bande de papier sur l'adhésif fugitif. Bien entendu, l'adhésif "fugitif" peut aussi être appliqué à la bande de papier au lieu de la bande de base.As mentioned previously the base band 33 can be coated with a additional layer linked to the base band by a layer of "fugitive" adhesive. In this case, it suffices to provide, upstream of the deposit station 25 of the sheets intermediaries 5, a printing station which applies the "fugitive" adhesive on the face top of the base strip, and a station for applying a strip of paper on the fugitive adhesive. Of course, the "fugitive" adhesive can also be applied to the strip of paper instead of the base strip.
