Description

DISPOSITIF DE MARQUAGE ADHÉSIF COMPORTANT UN FILM SUPPORT ET PROCÉDÉ DE RÉALISATION D'UN TEL DISPOSITIF ADHESIVE MARKING DEVICE COMPRISING A SUPPORT FILM AND METHOD FOR PRODUCING SUCH A DEVICE
L'invention concerne un dispositif de marquage adhésif, par exemple pour l'apposition de mentions informatives ou d'éléments décoratifs, sur des surfaces planes ou complexes telles que des carrosseries et plus particulièrement sur des véhicules tels que trains, aéronefs, etc. tant à l'extérieur qu'à l'intérieur de ceux-ci. L'invention concerne également un procédé de réalisation d'un tel dispositif de marquage. Dans la suite de la présente description, on utilisera un aéronef à titre de cas d'emploi exemplaire, sans que ceci puisse être interprété comme limitatif et excluant un autre type de véhicule, de carrosserie ou de surface sur lesquels le dispositif de marquage selon l'invention pourrait être apposé.The invention relates to an adhesive marking device, for example for affixing informative notes or decorative elements, on flat or complex surfaces such as bodies and more particularly on vehicles such as trains, aircraft, etc. both outside and inside of them. The invention also relates to a method for producing such a marking device. In the following description, an aircraft will be used as an exemplary use case, without this being interpreted as limiting and excluding another type of vehicle, body or surface on which the marking device according to the invention. invention could be affixed.
De nombreux marquages doivent être apposés dans et sur les aéronefs. Ces marquages peuvent être informatifs, utilisant du texte et/ou des pictogrammes ou décoratifs comme par exemple les logos des compagnies aériennes, dont certains utilisent des images ou photographies en couleur. Ces marquages, et en particulier ceux relatifs à la sécurité, doivent présenter une solidité et une tenue dans le temps et aux agressions des agents extérieurs (chimiques, climatiques, mécaniques, etc.) qui entrainent de nombreuses contraintes sur les procédés de marquage employés. Les techniques de peinture directe ou avec pochoirs peuvent convenir pour des motifs de grande taille avec peu de couleurs, mais pour des motifs exigeant une grande résolution et/ou des couleurs variables comme des photographies, l'étiquette adhésive ou le transfert restent des solutions incontournables.Many markings must be affixed in and on aircraft. These markings can be informative, using text and / or pictograms or decorative such as airline logos, some of which use images or color photographs. These markings, and in particular those relating to safety, must have strength and durability over time and the aggressions of external agents (chemical, climatic, mechanical, etc.) which cause many constraints on the marking processes used. Direct or stencil painting techniques may be suitable for large patterns with few colors, but for reasons requiring high resolution and / or variable colors such as photographs, the adhesive label or the transfer remain unavoidable solutions .
On connaît, par exemple du document WO2007/021550, des dispositifs de marquage par étiquette ou par transfert adaptés pour un marquage sur aéronef. On distingue l'étiquette du transfert en ce que le motif de marquage est réalisé au dessus d'un film support pour une étiquette (par rapport à une couche de colle destinée au report du dispositif sur un substrat) alors que pour un transfert, le marquage est réalisé entre le film support et la couche de colle. L'étiquette adhésive proposée par le document précité est constituée d'un film support en polymère portant sur une face un motif de marquage et sur la face opposée une couche de colle sensible à la pression. Pour que l'étiquette puisse avoir la solidité voulue, le document précise que ces trois couches doivent être chimiquement compatibles entre elles et avec le revêtement du substrat sur lequel l'étiquette doit être apposée ainsi qu'avec un vernis qui recouvre d'une couche continue l'étiquette et le substrat. Cette exigence de compatibilité, particulièrement entre les encres ou peintures formant le motif de marquage et le film support entraine la constitution de « systèmes » dans lesquels chaque fabricant propose son film support et les encres de marquage associées. A noter que, en particulier pour les étiquettes transparentes, la surface lisse et polie du film support nécessitée par le brillant et la transparence de l'étiquette, doit recevoir une couche d'apprêt, elle aussi compatible, permettant l'adhésion des encres.For example, document WO2007 / 021550 discloses tagging or transfer marking devices adapted for aircraft marking. The label of the transfer is distinguished in that the marking pattern is made above a support film for a label (with respect to a layer of adhesive intended to transfer the device to a substrate) whereas for a transfer, the marking is made between the support film and the adhesive layer. The adhesive label proposed by the aforementioned document consists of a polymer support film bearing on one side a marking pattern and on the opposite side a layer of pressure-sensitive adhesive. For the label to have the desired strength, the document states that these three layers must be chemically compatible with each other and with the coating of the substrate to which the label is to be affixed and with a varnish that covers a layer continue the label and the substrate. This compatibility requirement, particularly between the inks or paints forming the marking pattern and the support film leads to the constitution of "systems" in which each manufacturer offers its support film and the associated marking inks. Note that, especially for transparent labels, the smooth and polished surface of the support film required by the gloss and transparency of the label, must receive a primer, also compatible, allowing the adhesion of inks.
On comprend donc que le fabricant d'étiquettes, qui travaille souvent sur de petites séries, particulièrement en aéronautique, soit ainsi prisonnier des fabricants des films support et des systèmes d'encres associés. De ce fait, certaines exigences techniques ne peuvent être respectées faute de trouver un « système » adapté couvrant l'ensemble de ces exigences. Par exemple, tel fabricant de film support transparent le fournira en vinyle fragile au rayonnement ultraviolet alors qu'un autre, fournissant un film polyester résistant aura un système d'encres incompatible avec les produits chimiques employés dans l'environnement de l'étiquette (par exemple kérosène ou SKYDROL® en aéronautique...)It is therefore understandable that the label manufacturer, who often works on small series, particularly in aeronautics, is thus a prisoner of the manufacturers of support films and associated ink systems. As a result, certain technical requirements can not be met because of the lack of a suitable "system" covering all these requirements. For example, a manufacturer of transparent carrier film will provide it with ultraviolet-brittle vinyl, while another, providing a strong polyester film will have an ink system incompatible with the chemicals used in the label environment (eg example kerosene or SKYDROL® in aeronautics ...)
En outre, l'impossibilité d'utiliser les encres d'un fabricant X avec le film du fabricant Y en raison d'apprêts différents et souvent chimiquement incompatibles entraine des problèmes de gestion des stocks et de qualité en cas de mélange.In addition, the impossibility of using the inks of a manufacturer X with the film of the manufacturer Y because of different and often chemically incompatible primers causes problems of stock management and quality in case of mixing.
L'invention vise donc à proposer un dispositif de marquage adhésif permettant de remplir des exigences variées sans devoir utiliser de multiples « systèmes » de films support et d'encres associées. L'invention vise également à fournir un tel dispositif de marquage dont le film support soit compatible avec une grande variété d'encres et/ou de peintures et de procédés d'application de celles-ci.The invention therefore aims to provide an adhesive marking device to fulfill various requirements without having to use multiple "systems" of support films and associated inks. The invention also aims to provide such a marking device whose support film is compatible with a wide variety of inks and / or paints and methods of applying the same.
L'invention vise également à fournir un tel dispositif de marquage qui soit d'un coût de fabrication réduit et dont le procédé de fabrication est simplifié par rapport aux étiquettes connues. L'invention vise en outre un dispositif de marquage utilisable sur une grande variété de substrats, lisses ou textures.The invention also aims to provide such a marking device which is of a reduced manufacturing cost and whose manufacturing process is simplified compared to known labels. The invention further provides a marking device for use on a wide variety of substrates, smooth or textured.
L'invention vise en outre un dispositif de marquage qui puisse être réalisé en utilisant les mêmes peintures que celles employées pour le substrat (carlingue d'avion par exemple) sur lequel le dispositif de marquage est susceptible d'être apposé, afin de remplacer les décors adhésifs réalisés avec des films teintés dans la masse qui présentent des différences parfois notables de teinte avec les peintures précitées.The invention also relates to a marking device that can be produced using the same paints as those used for the substrate (aircraft cabin for example) on which the marking device is likely to be affixed, in order to replace the adhesive decorations made with tinted films in the mass that sometimes have differences in color with the aforementioned paintings.
L'invention vise encore un dispositif de marquage qui permette la réalisation de décors artistiques uniques sans requérir l'immobilisation de l'objet (avion par exemple) sur lequel le décor doit être apposé.The invention also relates to a marking device that allows the realization of unique artistic scenery without requiring the immobilization of the object (aircraft for example) on which the decor must be affixed.
Pour ce faire, l'invention concerne un dispositif de marquage adhésif, comportant un film support en matière synthétique portant sur une première face, dite face supérieure, au moins un motif de marquage recouvert d'une couche de vernis de protection et sur une seconde face opposée à la première, dite face inférieure, une couche d'adhésif sensible à la pression protégée par une feuille de protection, caractérisé en ce que le film support est un film polyester d'épaisseur comprise entre 20 et 50 μm dont les deux faces présentent un état de surface dépoli d'une rugosité adaptée pour obtenir une énergie de surface au moins égale à 58 mN/m selon la norme ASTM D2578. A noter que dans la description qui va suivre, on utilise les termes de « dessus », « dessous », supérieur(e), inférieur(e) et analogues pour définir une relation d'ordre entre les différentes couches ou films constituant le dispositif de marquage selon l'invention et/ou leurs faces respectives, par référence à un axe normal à la surface du substrat sur lequel le dispositif de marquage doit être apposé et orienté du substrat vers l'extérieur du dispositif de marquage.To do this, the invention relates to an adhesive marking device, comprising a synthetic support film on a first face, said upper face, at least one marking pattern covered with a layer of protective varnish and on a second opposite side to the first, said lower face, a layer of pressure-sensitive adhesive protected by a protective sheet, characterized in that the support film is a polyester film with a thickness of between 20 and 50 μm, both sides of which have a state of frosted surface with a roughness adapted to obtain a surface energy of at least 58 mN / m according to the ASTM D2578 standard. Note that in the following description, the terms "above", "below", "above", "below" and the like are used to define a sequence relationship between the various layers or films constituting the device. marking according to the invention and / or their respective faces, with reference to an axis normal to the surface of the substrate on which the marking device is to be affixed and oriented from the substrate to the outside of the marking device.
Le dépoli, qu'il soit réalisé par un brossage ou griffage mécanique de la surface du film ou, préférentiellement, par une attaque chimique, augmente la rugosité de la surface du film support, supprime l'aspect lisse et poli du film brut obtenu par calandrage ou coulée, améliore la mouillabilité et permet une bonne adhérence des encres de marquage de types et de provenances variées sur la surface du film sans requérir de couche d'apprêt ou de compatibilité chimique. Cet état de surface, qui a pour effet secondaire de rendre la surface du film terne et lui donne un aspect laiteux lorsque le film est transparent, va apparemment à rencontre du but recherché qui est d'obtenir un dispositif de marquage présentant un fort brillant et une très grande transparence. Les inventeurs ont cependant constaté que de manière surprenante, l'application ultérieure d'un vernis transparent sur la face supérieure du film permettait non seulement de rendre son brillant au dispositif de marquage, mais aussi, en combinaison avec une couche d'adhésif transparent appliqué sur la face inférieure du film, de restituer une parfaite transparence au dispositif de marquage. Avantageusement et selon l'invention, le film support est un film transparent en polyéthylène téréphtalate (PET), d'une épaisseur comprise entre 20 et 30 μm. Un tel matériau, difficilement utilisable jusqu'alors à cause de la mauvaise tenue des encres et peintures sur sa surface, permet maintenant de satisfaire des exigences de tenue environnementale auxquelles les films transparents vinyliques ne résistaient pas et offre simultanément une résistance au rayonnement UV hors de portée des polyesters habituellement employés.The frosted, whether done by brushing or scratching mechanically of the surface of the film or, preferably, by a chemical etching, increases the roughness of the surface of the support film, removes the smooth and polished appearance of the raw film obtained by calendering or casting, improves the wettability and allows a good adhesion of marking inks of various types and provenances on the film surface without requiring primer or chemical compatibility. This surface condition, which has the side effect of making the surface of the film dull and gives it a milky appearance when the film is transparent, apparently goes against the goal of obtaining a marking device having a high gloss and a very great transparency. The inventors, however, have found that, surprisingly, the subsequent application of a transparent varnish on the upper face of the film makes it possible not only to render its gloss to the marking device, but also, in combination with a layer of transparent adhesive applied. on the underside of the film, to restore a perfect transparency to the marking device. Advantageously and according to the invention, the support film is a transparent polyethylene terephthalate (PET) film with a thickness of between 20 and 30 μm. Such a material, previously difficult to use because of the poor resistance of inks and paints on its surface, now satisfies the environmental requirements to which the transparent vinyl films do not resist and simultaneously offers resistance to UV radiation out of range of polyesters usually employed.
Avantageusement et selon l'invention, le dispositif de marquage comporte une couche d'adhésif sensible à la pression qui présente une épaisseur comprise entre une et trois fois l'épaisseur du film support, avec une épaisseur minimale de 50 μm. Une telle épaisseur de colle, supérieure à l'épaisseur couramment rencontrée dans les étiquettes autocollantes présente de nombreux avantages parmi lesquels une rigidité améliorée du complexe film support / colle / film protecteur permettant son emploi en sérigraphie sur table aspirante sans déformation, un meilleur pouvoir adhésif et une meilleure compensation des dilatations différentielles entre le substrat et le dispositif de marquage lorsque celui- ci est apposé sur son substrat sans pour cela entrainer des risques de décohésion entre la colle et le film support grâce à la capacité d'adhérence renforcée offerte par la surface dépolie de la face inférieure du film support.Advantageously and according to the invention, the marking device comprises a layer of pressure-sensitive adhesive which has a thickness of between one and three times the thickness of the support film, with a minimum thickness of 50 μm. Such an adhesive thickness, which is greater than the thickness commonly encountered in self-adhesive labels, has many advantages, among them an improved rigidity of the support film / glue / protective film complex enabling it to be used in screen printing on a suction table without deformation, a better adhesive power. and a better compensation of the differential expansions between the substrate and the marking device when it is affixed to its substrate without thereby causing risks of decohesion between the glue and the support film thanks to the reinforced adhesion capacity offered by the frosted surface of the underside of the support film.
Avantageusement et selon l'invention, la couche d'adhésif sensible à la pression présente une épaisseur au moins égale à 100 μm adaptée pour le collage dudit dispositif de marquage sur des surfaces texturées. Il est ainsi possible d'apposer aisément et avec une grande fiabilité le dispositif de marquage sur des surfaces telles que des panneaux graines formant les parois intérieures de la cabine des aéronefs, ou des parois internes en fibre de carbone des nacelles moteur, alors qu'il était nécessaire auparavant d'apposer des marquages sur des étiquettes métalliques vissées ou rivetées.Advantageously and according to the invention, the pressure-sensitive adhesive layer has a thickness at least equal to 100 μm adapted for bonding said marking device on textured surfaces. It is thus possible to easily and reliably affix the marking device on surfaces such as seed panels forming the interior walls of the cabin of the aircraft, or the internal walls of carbon fiber engine pods, while it was previously necessary to affix markings on metal tags screwed or riveted.
Avantageusement et selon l'invention, le film support porte sur sa face supérieure un motif de marquage en contact direct avec ledit film. Grâce à la rugosité du film support dépoli, et à l'importante énergie de surface qu'il permet, il n'est plus nécessaire d'interposer une couche de primaire d'accrochage entre le film support et l'encre appliquée sur le film.Advantageously and according to the invention, the support film carries on its upper face a marking pattern in direct contact with said film. Thanks to the roughness of the frosted support film, and to the large surface energy that it allows, it is no longer necessary to interpose a layer of primer between the support film and the ink applied to the film .
En outre, le motif de marquage présente une adhérence minimale sur le film support d'au moins 2,6 MPa suivant la norme ISO 4624. En effet, la rugosité du film support obtenue par l'état de surface dépoli permet non seulement d'augmenter la mouillabilité du support mais de renforcer la capacité d'adhérence des encres et vernis qui y sont déposés.In addition, the marking pattern has a minimum adhesion on the support film of at least 2.6 MPa according to ISO 4624. Indeed, the roughness of the support film obtained by the frosted surface state not only allows for to increase the wettability of the support but to reinforce the adhesion capacity of the inks and varnishes deposited there.
Avantageusement et selon l'invention, le motif de marquage et la face supérieure du film support sont recouverts par une couche de vernis de protection assurant un lissage optique de la face supérieure du film support et une fonction technique d'interface avec le milieu extérieur. L'application d'au moins une couche de vernis au dessus du motif de marquage et particulièrement entre les éléments du motif, directement sur la face supérieure du film support permet le bouchage des pores ou micro-rayures de cette face, lui rendant l'aspect brillant d'un film coulé ou calandre lisse de la technique antérieure.Advantageously and according to the invention, the marking pattern and the upper face of the support film are covered by a layer of protective varnish ensuring an optical smoothing of the upper face of the support film and a technical interface function with the external medium. The application of at least one layer of varnish above the marking pattern and particularly between the elements of the pattern, directly on the upper face of the support film makes it possible to block the pores or micro-scratches of this face, rendering it the glossy appearance of a cast film or smooth calender of the prior art.
Avantageusement et selon l'invention, lorsque le dispositif de marquage est adapté pour être appliqué sur un substrat destiné à être recouvert après application par un revêtement de finition, le vernis de protection formant ladite couche est compatible avec ce revêtement de finition. Le vernis présente une adhérence améliorée sur la face supérieure dépolie du film support, ce qui permet d'utiliser directement un vernis compatible avec les peintures et revêtements utilisés pour le substrat sur lequel le dispositif de marquage doit être apposé. De ce fait, par exemple pour l'apposition de marquages sur la carlingue d'un avion, il est possible de coller le dispositif de marquage et de le recouvrir en même temps que la carlingue d'un vernis de finition agréé par les fabricants d'avions et/ou les compagnies aériennes.Advantageously and according to the invention, when the marking device is adapted to be applied to a substrate intended to be covered after application by a finishing coating, the protective varnish forming said layer is compatible with this finish coating. The varnish has an improved adhesion to the frosted upper surface of the support film, which makes it possible to directly use a varnish compatible with the paints and coatings used for the substrate on which the marking device is to be affixed. Therefore, for example for the affixing of markings on the cabin of an aircraft, it is possible to glue the marking device and cover it together with the cabin with a finishing varnish approved by the manufacturers. planes and / or airlines.
Avantageusement et selon l'invention, le vernis de protection est choisi dans un ensemble de compositions assurant, individuellement ou en combinaison, que la surface externe du dispositif de marquage présente des propriétés mécaniques et/ou chimiques de résistance aux graffitis, aux salissures, aux rayures, à l'abrasion, aux chocs, aux produits chimiques et/ou des propriétés antidérapantes. Grâce aux propriétés de mouillabilité et d'adhérence conférées par la surface dépolie du film support, il est maintenant possible d'utiliser de nombreuses compositions de peintures transparentes et de vernis susceptibles de conférer ces propriétés au dispositif de marquage mais qui étaient jusqu'à présent incompatibles avec les films support connus. On remplace ainsi avantageusement les films de pelliculage coûteux et difficiles à mettre en œuvre utilisés jusqu'alors. Avantageusement et selon l'invention, lorsque le dispositif de marquage est adapté pour être appliqué sur un substrat destiné à être recouvert après application par un revêtement de finition, la face extérieure de la couche de vernis de protection présente un état de surface propre à faciliter l'adhérence du revêtement de finition sur le dispositif de marquage. Par exemple, la face extérieure de la couche de vernis de protection comporte un dépoli présentant des propriétés analogues au dépoli du film support afin de permettre un recouvrement sans discontinuité du substrat et du dispositif de marquage par le revêtement de finition.Advantageously and according to the invention, the protective varnish is chosen from a set of compositions ensuring, individually or in combination, that the external surface of the marking device has mechanical and / or chemical properties of resistance to graffiti, dirt, scratches, abrasion, impact, chemicals and / or anti-slip properties. Owing to the wettability and adhesion properties of the frosted surface of the support film, it is now possible to use a large number of transparent paint and varnish compositions capable of imparting these properties to the marking device but which have hitherto been incompatible with known support films. Advantageously, the expensive and difficult to use filming films used until now are replaced. Advantageously and according to the invention, when the marking device is adapted to be applied to a substrate intended to be covered after application by a finishing coating, the outer face of the protective varnish layer has a clean surface state to facilitate the adhesion of the finishing coating to the marking device. For example, the outer face of the protective varnish layer comprises a frosting having properties similar to the frosting of the support film to allow a seamless coverage of the substrate and the marking device by the finishing coating.
Avantageusement et selon l'invention, lorsque le dispositif de marquage est adapté pour être appliqué sur un substrat recouvert par une peinture, le film support est revêtu d'une peinture identique à ladite peinture. Disposer de surfaces de film autocollant recouvertes avec la même peinture servant à peindre tout ou partie de la carlingue d'un avion permet de réaliser des décors autocollants dont la teinte est identique à la peinture choisie, au contraire des films teintés dans la masse utilisés jusqu'alors dont la palette restreinte limitait les choix. En outre il est désormais possible de peindre un décor artistique unique sur un véhicule ou tout autre substrat sans avoir à l'immobiliser pendant le temps d'exécution de l'œuvre. Grâce au dispositif de marquage de l'invention, l'œuvre est réalisée sur une surface de film support puis reportée sur le véhicule.Advantageously and according to the invention, when the marking device is adapted to be applied to a substrate covered by a paint, the support film is coated with a paint identical to said paint. Have self-adhesive film surfaces covered with the same paint used to paint all or part of the cabin of an aircraft allows for self-adhesive decorations whose hue is identical to the chosen paint, unlike the tinted films used until then whose limited range limited choices. In addition it is now possible to paint a unique artistic decor on a vehicle or other substrate without having to immobilize during the execution time of the work. Thanks to the marking device of the invention, the work is performed on a support film surface and then transferred to the vehicle.
Avantageusement et selon l'invention, le dispositif de marquage comprend en outre un film de manipulation faiblement adhésif collé sur sa face supérieure. Un tel film de manipulation, généralement en papier ou en polyéthylène transparent ou semi transparent enduit d'un adhésif caoutchouc de faible pouvoir adhésif ne laissant pas de résidu sur la surface externe du dispositif de marquage permet d'apposer celui-ci avec précision.Advantageously and according to the invention, the marking device further comprises a weakly adhesive handling film stuck on its upper face. Such a handling film, generally made of paper or transparent or semi-transparent polyethylene coated with a low adhesion adhesive rubber adhesive leaving no residue on the outer surface of the marking device allows to affix it accurately.
L'invention s'étend également à un procédé de réalisation d'un dispositif de marquage présentant au moins l'une des caractéristiques énoncées ci-dessus, caractérisé en ce que : on choisit à titre de film support un film polyester d'épaisseur comprise entre 20 et 50 μm dont les deux faces présentent un état de surface dépoli d'une rugosité adaptée pour obtenir une énergie de surface au moins égale à 58 mN/m selon la norme ASTM D2578, on applique une couche d'adhésif sur la face inférieure du film support, on imprime un motif de marquage sur la face supérieure dudit film support, - on recouvre le motif de marquage et les parties du film support non recouvertes par celui-ci avec une couche de vernis, on découpe le contour du dispositif de marquage on recouvre le vernis par un film de manipulation transparent.The invention also extends to a method of producing a marking device having at least one of the features set out above, characterized in that: a polyester film of thickness between 20 and 50 μm whose two faces have a ground surface state of a roughness adapted to obtain a surface energy of at least 58 mN / m according to ASTM D2578, a layer of adhesive is applied to the face bottom of the support film, a marking pattern is printed on the upper face of said support film, - the marking pattern and the parts of the support film not covered by it are covered with a layer of varnish, the outline of the device is cut off the varnish is covered by a transparent handling film.
Selon le procédé de l'invention, la couche de colle appliquée au film polyester dépoli peut être appliquée par le fabricant du film support si des quantités minimum sont commandées, mais elle peut être également appliquée par le fabricant du dispositif de marquage pour des surfaces plus réduites, permettant ainsi au fabricant du dispositif de marquage de choisir la colle appropriée, dans son épaisseur, sa nature et son pouvoir adhésif, à l'application envisagée. Un tel procédé est donc plus souple et plus adaptable aux besoins. Avantageusement et selon l'invention, on applique la couche de colle par colaminage d'un film de colle acrylique et du film support dépoli. Préférentiellement, en fonction de la nature et de l'épaisseur du film de colle, le laminage est effectué à chaud. En particulier, et toujours selon l'invention, lorsque le film support est transparent, le laminage est opéré dans une atmosphère contrôlée et dépoussiérée.According to the method of the invention, the layer of glue applied to the frosted polyester film can be applied by the carrier film manufacturer if minimum quantities are ordered, but it can also be applied by the manufacturer of the marking device for smaller surfaces, thus allowing the manufacturer of the marking device to choose the appropriate adhesive, in its thickness, its nature and its adhesive power, the intended application. Such a process is therefore more flexible and more adaptable to the needs. Advantageously and according to the invention, the adhesive layer is applied by bonding an acrylic adhesive film and the frosted backing film. Preferably, depending on the nature and thickness of the adhesive film, the rolling is carried out hot. In particular, and still according to the invention, when the support film is transparent, the rolling is operated in a controlled atmosphere and dusted.
Avantageusement et selon l'invention, on imprime le motif de marquage par impression numérique au jet d'encre. Il est ainsi possible, même pour de petites séries, voire même pour des pièces unitaires, de réaliser des étiquettes mono ou polychromes, le cas échéant de qualité photographique, à partir d'une définition sous forme d'un fichier numérique.Advantageously and according to the invention, the printing pattern is printed by digital ink jet printing. It is thus possible, even for small series, or even for single pieces, to produce mono or polychrome labels, where appropriate of photographic quality, from a definition in the form of a digital file.
Alternativement et selon l'invention, on imprime le motif de marquage par sérigraphie. Pour de plus grandes séries, le même film support peut être utilisé avec des encres de sérigraphie de diverses provenances et on a pu constater que, de manière surprenante, les motifs ainsi réalisés présentaient une durée de séchage fortement réduite par rapport aux mêmes motifs réalisés par sérigraphie sur des films à surface lisse de la technique antérieure.Alternatively and according to the invention, the marking pattern is printed by screen printing. For larger series, the same support film can be used with screen printing inks of various origins and it was found that, surprisingly, the patterns thus produced had a greatly reduced drying time compared to the same patterns made by screen printing on smooth surface films of the prior art.
Avantageusement et selon l'invention, l'étape de recouvrement du motif de marquage et du film support avec une couche de vernis est réalisée par sérigraphie. Alternativement et selon l'invention, l'étape de recouvrement du motif de marquage et du film support avec une couche de vernis est réalisée par pulvérisation.Advantageously and according to the invention, the step of covering the marking pattern and the support film with a layer of varnish is performed by screen printing. Alternatively and according to the invention, the step of covering the marking pattern and the support film with a layer of varnish is carried out by spraying.
Avantageusement et selon l'invention, on insère une étape de traitement de la surface extérieure de la couche de vernis avant l'étape de recouvrement du vernis par un film de manipulation. Ce traitement de surface peut être opéré par un dépoli mécanique ou chimique de la face supérieure du vernis ou encore par un nettoyage avec un solvant, afin de promouvoir l'adhérence d'une couche de revêtement de finition ultérieure sur le dispositif de marquage.Advantageously and according to the invention, a step of treating the outer surface of the varnish layer is inserted before the step of covering the varnish with a handling film. This surface treatment can be operated by a mechanical or chemical frosting of the upper face of the varnish or again by cleaning with a solvent, to promote the adhesion of a subsequent coating layer to the marking device.
Ainsi, l'utilisateur peut se dispenser de réaliser les opérations usuelles de préparation de surface au moment du report du dispositif de marquage et du vernissage de celui-ci sur le support.Thus, the user can dispense with performing the usual surface preparation operations at the time of the transfer of the marking device and the coating thereof on the support.
Ces opérations ayant été réalisées lors de la fabrication du dispositif de marquage, elles ne sont plus nécessaires lors de la mise en œuvre de celui-ci, mise en œuvre qui est alors plus économique.These operations having been performed during the manufacture of the marking device, they are no longer necessary during the implementation of it, implementation which is then more economical.
L'invention concerne également un dispositif de marquage et un procédé de réalisation de ce dispositif caractérisé en combinaison par tout ou partie des caractéristiques mentionnées ci-dessus ou ci-après.The invention also relates to a marking device and a method of producing this device characterized in combination by all or some of the characteristics mentioned above or below.
D'autres buts, caractéristiques et avantages de l'invention apparaîtront au vu de la description qui va suivre et des dessins annexés dans lesquels : - la figure 1 est une vue schématique en coupe d'un dispositif de marquage selon l'invention, avant apposition sur un substrat, et la figure 2 est une vue schématique en coupe du même dispositif de marquage selon l'invention, après apposition sur un substrat et protection de celui-ci, et - la figure 3 représente une vue schématique du déroulement du procédé de réalisation d'un dispositif de marquage selon l'invention.Other objects, features and advantages of the invention will become apparent from the following description and the accompanying drawings, in which: FIG. 1 is a schematic sectional view of a marking device according to the invention, before apposition to a substrate, and Figure 2 is a schematic sectional view of the same marking device according to the invention, after apposition to a substrate and protection thereof, and - Figure 3 shows a schematic view of the process flow embodiment of a marking device according to the invention.
Sur les figures, les échelles ne sont pas respectées, et ce à des fins d'illustration ; en particulier, les épaisseurs sont exagérément agrandies.In the figures, the scales are not respected, and this for the purposes of illustration; in particular, the thicknesses are exaggeratedly enlarged.
Le dispositif de marquage 1 représentée en coupe sur la figure 1 comporte de manière centrale un film support 2 polymère, plus particulièrement un film polyester d'épaisseur comprise entre 20 et 50 μm. Le film support 2 peut être constitué de polyester comportant un pigment le rendant opaque, par exemple une charge d'oxyde de titane (TiO2) donnant un film support blanc opaque ou bien constitué de polyéthylène téréphtalate (PET) qui présente l'avantage d'être transparent, d'une grande limpidité et très résistant au rayonnement ultraviolet.The marking device 1 shown in section in FIG. 1 centrally comprises a polymer support film 2, more particularly a polyester film with a thickness of between 20 and 50 μm. The support film 2 can be made of polyester comprising a pigment which makes it opaque, for example a titanium oxide (TiO 2 ) filler giving an opaque white support film or consisting of polyethylene terephthalate (PET) which has the advantage of be transparent, of great clarity and very resistant to ultraviolet radiation.
Le film support 2 a subi un traitement de surface sur ses deux faces, consistant en un dépolissage de sa surface par des moyens mécaniques ou chimiques. Par exemple, le film support peut avoir été soumis à un brossage mécanique, croisé ou non, au moyen de lanières émerisées, de manière à créer à la surface du film un réseau de rayures microscopiques. Alternativement, et de manière préférentielle, le dépolissage peut être réalisé par des moyens chimiques, par exemple en soumettant le film support 2 à un bain ou une aspersion au moyen d'acides ou autres produits adaptés pour attaquer la surface du film sur une très faible épaisseur, de l'ordre de quelques fractions de microns. Un dépolissage chimique est préféré en ce qu'il risque moins de laisser des résidus (grains d'abrasif) inclus dans la surface du film ou collés dessus, ce qui pourrait être préjudiciable aux opérations ultérieures.The support film 2 has undergone a surface treatment on its two faces, consisting of a roughening of its surface by mechanical or chemical means. For example, the support film may have been subjected to mechanical brushing, crossed or not, by means of emerized strips, so as to create on the surface of the film a network of microscopic stripes. Alternatively, and preferably, the etching can be carried out by chemical means, for example by subjecting the support film 2 to a bath or spraying with acids or other products adapted to attack the surface of the film on a very weak thickness, of the order of a few fractions of microns. A chemical etching is preferred in that it is less likely to leave residues (abrasive grains) included in the surface of the film or glued on, which could be detrimental to subsequent operations.
Le film support 2 est lié sur sa face inférieure à une couche 3 d'adhésif sensible à la pression à froid (c'est-à-dire à la température ambiante). Par exemple, on peut utiliser avantageusement une composition d'adhésif transparent, de type acrylique, résistant aux ultraviolets. La composition et l'épaisseur de cette couche 3 d'adhésif sont choisies en fonction de l'application, et en particulier de la nature et des caractéristiques (notamment état de surface) de la surface du substrat 10 ou de son revêtement 11 sur lequel le dispositif de marquage doit être apposé.The support film 2 is bonded on its underside to a layer 3 of pressure sensitive adhesive cold (that is to say at room temperature). For example, a transparent, acrylic-type, ultraviolet-resistant adhesive composition can be advantageously used. The composition and the thickness of this adhesive layer 3 are chosen as a function of the application, and in particular of the nature and characteristics (in particular surface state) of the surface of the substrate 10 or of its coating 11 on which the marking device must be affixed.
De manière générale, la couche 3 d'adhésif présente une épaisseur au moins égale à l'épaisseur du film support 2, et en général de l'ordre de une à trois fois cette épaisseur, avec un minimum de 50 μm. Cette épaisseur permet d'améliorer l'adhésion du dispositif de marquage sur un substrat métallique par exemple, et de compenser plus aisément des variations de taille relative entre le dispositif de marquage et le substrat qu'il recouvre lors de grandes variations de température, telles que celles rencontrées par un avion, entre -500C en vol et +500C en stationnement au sol.In general, the layer 3 of adhesive has a thickness at least equal to the thickness of the support film 2, and in general of the order of one to three times this thickness, with a minimum of 50 microns. This thickness makes it possible to improve the adhesion of the marking device to a metal substrate for example, and to more easily compensate for variations in relative size between the marking device and the substrate that it covers during large temperature variations, such as than those encountered by an aircraft, between -50 0 C in flight and +50 0 C in ground parking.
Dans certains cas particuliers d'emploi du dispositif de marquage selon l'invention, il peut être nécessaire d'augmenter l'épaisseur de la couche 3 de colle, par exemple jusqu'à 100 μm et au-delà, pour prendre en compte un état de surface texture du substrat, comme par exemple les parois grainées de l'intérieur d'un avion ou les surfaces internes des nacelles des moteurs qui sont en fibres de carbone. Grâce à la forte épaisseur de la couche de colle 3, celle-ci peut fluer autour des aspérités du substrat et combler les creux, permettant ainsi l'adhésion du dispositif de marquage.In particular cases of use of the marking device according to the invention, it may be necessary to increase the thickness of the adhesive layer 3, for example up to 100 μm and beyond, in order to take into account a texture surface condition of the substrate, such as for example the grain walls of the interior of an aircraft or the internal surfaces of the nacelles of the engines which are in carbon fibers. Thanks to the high thickness of the adhesive layer 3, it can flow around the asperities of the substrate and fill the hollows, thus allowing the adhesion of the marking device.
La couche 3 d'adhésif est recouverte d'une feuille 4 de protection par exemple en papier siliconé pouvant être aisément séparée avant utilisation du dispositif de marquage. La couche 3 d'adhésif peut être reportée sur le film support 2 immédiatement après le dépolissage de celui-ci par le fabricant du film support si des quantités importantes de film support muni d'un type d'adhésif prédéterminé sont nécessaires. La couche 3 d'adhésif peut également être reportée sur le film support 2 au moment de la fabrication du dispositif de marquage, par un colaminage du film support 2 et d'un film de colle acrylique adapté au cahier des charges de le dispositif de marquage, comme présenté à l'étape SlOl du procédé de réalisation de le dispositif de marquage illustré à la figure 3. Le film de colle acrylique est maintenu sur une feuille de papier siliconé et appliqué sur le film support 2 par les cylindres de laminage.The adhesive layer 3 is covered with a protective sheet 4, for example made of silicone paper, which can be easily separated before use of the marking device. The adhesive layer 3 can be transferred onto the support film 2 immediately after the grinding thereof by the support film manufacturer if large amounts of carrier film with a predetermined type of adhesive are required. The adhesive layer 3 may also be transferred to the support film 2 at the time of manufacture of the marking device, by a roll of the support film 2 and an acrylic adhesive film adapted to the specifications of the marking device. , as presented in step SlOl of the method for producing the marking device illustrated in FIG. 3. The acrylic adhesive film is held on a sheet of silicone paper and applied to the support film 2 by the rolling rolls.
En particulier, lorsque le film support 2 est un film transparent, cette étape de laminage a lieu dans une salle dite blanche ou grise, c'est- à-dire dans un environnement contrôlé présentant un taux de poussières et particules en suspension dans l'air réduit afin de ne pas en emprisonner entre le film support 2 et la couche 3 d'adhésif. Le laminage du film de colle sur le film support est réalisé à température ambiante, ou bien à chaud pour une meilleure interpénétration. On a remarqué que le laminage et en particulier le laminage à chaud de la couche 3 d'adhésif sur le film support 2 permettait une solidarisation étroite par pénétration de la colle dans les micro aspérités de la surface du film support et qu'ainsi les risques de décohésion entre la couche 3 d'adhésif et le film support 2 étaient notablement réduits. En outre, pour un film support et un adhésif transparent, cette interpénétration permet de restituer sa limpidité à l'interface entre le film support 2 et la couche 3 d'adhésif.In particular, when the support film 2 is a transparent film, this rolling step takes place in a so-called white or gray room, that is to say in a controlled environment having a level of dust and particles suspended in the room. reduced air so as not to trap between the support film 2 and the layer 3 of adhesive. The rolling of the adhesive film on the support film is carried out at ambient temperature, or hot for better interpenetration. It has been noted that the rolling and in particular the hot rolling of the adhesive layer 3 on the support film 2 allowed a close bonding by penetration of the adhesive into the micro asperities of the surface of the support film and that the risks decohesion between the adhesive layer 3 and the support film 2 were significantly reduced. In addition, for a support film and a transparent adhesive, this interpenetration makes it possible to restore its clarity at the interface between the support film 2 and the adhesive layer 3.
Le colaminage du film support et de la couche d'adhésif dans les premières étapes de la fabrication du dispositif de marquage permet également, compte tenu de la relative rigidité de la feuille de protection 4 de la couche d'adhésif, d'obtenir un « complexe » (film support, couche d'adhésif, feuille de protection) sous la forme d'une feuille suffisamment rigide pour être manipulée et, en particulier, fixée par aspiration sur des tables d'impression ou de sérigraphie sans entrainer de déformation ou de marques sur la feuille. Dans l'étape S 102 suivante du procédé de réalisation du dispositif de marquage, on imprime un motif 5 de marquage sur la face supérieure du film support. Grâce à l'état de surface dépoli du film support 2 qui présente une certaine rugosité, de nombreuses encres peuvent couvrir cette surface sans présenter de refus comme c'est le cas avec des surfaces lisses. Il n'est donc plus nécessaire d'utiliser des encres spécialement adaptées à tel ou tel type de film support, encres qui ne seraient pas adaptées à différents procédés de report sur le film.The bonding of the support film and the adhesive layer in the first stages of the manufacture of the marking device also makes it possible, given the relative rigidity of the protective sheet 4 of the layer of adhesive, to obtain a "complex" (support film, adhesive layer, protective film) in the form of a sheet sufficiently rigid to be handled and, in particular, fixed by suction on printing tables or silkscreen without causing deformation or marks on the sheet. In the following step S 102 of the method of producing the marking device, a marking pattern 5 is printed on the upper face of the support film. Due to the frosted surface state of the support film 2 which has a certain roughness, many inks can cover this surface without being rejected as is the case with smooth surfaces. It is therefore no longer necessary to use inks specially adapted to this or that type of support film, inks that would not be suitable for different methods of transfer to the film.
En particulier, il est maintenant possible d'utiliser une large gamme d'encres adaptées pour le marquage par impression numérique au jet d'encre. Cette technique de marquage est particulièrement adaptée pour la réalisation de petites séries d'étiquettes, voire même de pièces unitaires car elle ne nécessite pas d'outillage particulier. En outre, l'impression numérique permet la réalisation de motifs de marquage de type photographique. Dans cette technique, une tête d'impression se déplace au dessus de la face supérieure du film support 2 et projette par de nombreuses buses commandées individuellement des gouttelettes d'encre(s) colorée(s) qui forment le motif de marquage à réaliser.In particular, it is now possible to use a wide range of inks suitable for marking by digital inkjet printing. This marking technique is particularly suitable for producing small series of labels, or even single parts because it does not require special tools. In addition, digital printing allows the realization of photographic type marking patterns. In this technique, a print head moves over the upper face of the support film 2 and projects by numerous individually controlled nozzles droplets of ink (s) colored (s) which form the marking pattern to achieve.
Pour des séries d'étiquettes plus importantes, ou présentant une gamme de couleurs plus restreinte, la sérigraphie reste une technique de marquage très économique. L'utilisation d'un film support 2 présentant une surface dépolie permet dans cette technique également, d'employer une grande variété d'encres de sérigraphie, sans nécessairement avoir besoin d'appairer les systèmes d'encres avec le type de film support. Il est ainsi possible de réduire le nombre de références d'encres en stock et de minimiser les coûts liés à la péremption de nombreuses références d'encres. On a également remarqué que, quelle que soit la provenance des encres utilisées, leur pouvoir de couverture était amélioré et leur temps de séchage réduit. Par exemple, alors qu'il était nécessaire d'avoir un temps de séchage entre couches de l'ordre de 72 heures pour une encre appliquée sur un film support lisse utilisé jusqu'alors, le temps de séchage est réduit à moins d'une heure pour une impression sur le film support dépoli de l'invention.For larger series of labels, or with a more limited range of colors, screen printing remains a very economical marking technique. The use of a support film 2 having a frosted surface also makes it possible in this technique to use a wide variety of screen printing inks, without necessarily having to match the ink systems with the type of support film. It is thus possible to reduce the number of ink references in stock and to minimize the costs associated with the expiry of many ink references. It has also been noted that irrespective of the source of the inks used, their hiding power was improved and their drying time reduced. For example, while it was necessary to have an interlayer drying time of the order of 72 hours for an ink applied to a smooth support film used until then, the drying time is reduced to less than one hour for printing on the frosted backing film of the invention.
Quelle que soit la technique de marquage utilisée, le motif 5 de marquage reporté sur la face supérieure du film support 2 peut être continu ou discontinu, c'est-à-dire que certaines parties de la surface du film support peuvent ne pas être recouvertes d'encre, comme c'est le cas pour des marquages informatifs constitués de texte ou de symboles sur fond blanc ou transparent.Whatever the marking technique used, the marking pattern 5 carried on the upper face of the support film 2 may be continuous or discontinuous, that is to say that some parts of the surface of the support film may not be covered. as in the case of informative markings consisting of text or symbols on a white or transparent background.
Dans une étape suivante (S 103) du procédé de réalisation du dispositif de marquage, on dépose une couche 6 de vernis transparent sur toute la surface du dispositif de marquage. La couche 6 de vernis recouvre donc le motif 5 de marquage et la partie de la face supérieure du film support 2 qui n'est pas recouverte par le motif 5. Le vernis utilisé est par exemple un vernis compatible avec un revêtement destiné à recouvrir la surface sur laquelle est apposé le dispositif de marquage. Par exemple, comme illustré sur la figure 2, le dispositif de marquage 1 peut être apposé sur la surface externe d'une carlingue d'avion constituée d'un substrat 10 métallique (en général un alliage d'aluminium) éventuellement recouvert d'une peinture 11. Un revêtement 12 de finition, par exemple constitué d'une composition de peinture ou de vernis transparent, compatible avec la peinture 11, est destinée à recouvrir la carlingue de l'avion, y compris à l'endroit où sont apposées des étiquettes. A titre d'exemple de revêtement 12, on peut citer les produits de la gamme AVIOX® de la société AKZO-NOBEL qui comprennent un vernis « clearcoat » de finition et de protection.In a next step (S 103) of the method for producing the marking device, a layer 6 of transparent varnish is deposited on the entire surface of the marking device. The layer 6 of varnish thus covers the marking pattern 5 and the part of the upper face of the support film 2 which is not covered by the pattern 5. The varnish used is for example a varnish compatible with a coating intended to cover the surface. surface on which is affixed the marking device. For example, as illustrated in FIG. 2, the marking device 1 may be affixed to the outer surface of an aircraft cabin consisting of a metal substrate (generally an aluminum alloy) optionally covered with a 11. A finishing coating 12, for example consisting of a paint or clear lacquer composition, compatible with the paint 11, is intended to cover the cabin of the aircraft, including the place where are affixed tags. As an example of coating 12, mention may be made of the products of the AVIOX® range of the company AKZO-NOBEL which comprise a "clearcoat" varnish for finishing and protection.
La couche 6 de vernis déposée sur le dispositif de marquage 1 est avantageusement compatible avec ce revêtement 12, de telle sorte que lorsque le dispositif de marquage est apposé sur la carlingue de l'avion, il puisse être recouvert par le revêtement 12 sans qu'il y ait de problèmes de refus ou de réaction entre le revêtement 12 et la couche 6 de vernis du dispositif de marquage. Pour ce faire, il est possible, grâce aux propriétés d'adhérence renforcée du film support 2 dépoli, d'utiliser le même vernis ou un vernis de la même gamme que le revêtement 12 pour réaliser la couche 6.The layer 6 of varnish deposited on the marking device 1 is advantageously compatible with this coating 12, so that when the marking device is affixed to the cabin of the aircraft, it can be covered by the coating 12 without it. there are problems of refusal or reaction between the coating 12 and the coating layer 6 of the marking device. To do this, it is possible, thanks to the reinforced adhesion properties of the frosted support film 2, to use the same varnish or a varnish of the same range as the coating 12 to produce the layer 6.
La couche de vernis 6 peut être également constituée de compositions de peintures transparentes ou de vernis techniques permettant de conférer à la surface supérieure du dispositif de marquage des propriétés particulières. Par exemple, des vernis souples peuvent conférer des propriétés antichoc au dispositif de marquage, alors que des compositions d'une dureté importante une fois complètement polymérisées fourniront des propriétés antirayures. D'autres compositions encore permettent d'obtenir des propriétés antisalissures ou anti-graffitis. Toutes ces propriétés qui jusqu'à présent ne pouvaient être obtenues que par un pelliculage appliqué ultérieurement sur le dispositif de marquage du fait de l'incompatibilité de la majeure partie des compositions avec les systèmes d'encre existants peuvent maintenant être obtenues directement grâce à la tension de surface remarquable due au dépoli du film support.The varnish layer 6 may also consist of transparent paint compositions or technical varnishes for imparting special properties to the upper surface of the marking device. For example, soft varnishes can impart shockproof properties to the marking device, while compositions of high hardness once completely polymerized will provide anti-scratch properties. Still other compositions provide antifouling or anti-graffiti properties. All of these properties, which until now could only be obtained by subsequent coating on the marking device because of the incompatibility of most of the compositions with the existing ink systems, can now be obtained directly by means of remarkable surface tension due to the frosting of the support film.
La couche 6 de vernis recouvre la partie du film support 2 non recouverte par le motif 5 de marquage, pénètre dans les micro-aspérités de la surface du film support et restitue un état de surface lisse et brillant au dispositif de marquage. En outre, comme vu précédemment pour la couche 3 d'adhésif, dans le cas d'un film support 2 transparent, la pénétration du vernis dans les micro-aspérités de la surface élimine l'aspect laiteux du film support et lui rend une complète limpidité.The lacquer layer 6 covers the portion of the support film 2 not covered by the marking pattern 5, penetrates the micro-asperities of the surface of the support film and restores a smooth and shiny surface state to the marking device. In addition, as seen previously for the adhesive layer 3, in the case of a transparent support film 2, the penetration of the varnish in the micro-roughness of the surface eliminates the milky appearance of the support film and renders it complete. clarity.
La couche 6 de vernis peut être appliquée par sérigraphie sur une surface correspondant au dispositif de marquage fini, c'est-à-dire en laissant des intervalles non recouverts entre des étiquettes distinctes imprimées sur une même planche ou bien être appliquée par pulvérisation sur toute la planche.The lacquer layer 6 can be applied by screen printing to a surface corresponding to the finished marking device, i.e. leaving gaps not covered between separate labels printed on the same board or being sprayed on any the board.
Une fois la couche 6 de vernis sèche, une étape S 104 de découpe des différentes étiquettes réalisées sur une même planche est effectuée par des moyens classiques tels qu'une découpe à mi-chair du contour de chaque étiquette.Once the layer 6 of dry varnish, a step S 104 for cutting the different labels made on the same board is performed by conventional means such as a cut half-flesh contour of each label.
Avant ou préférentiellement après la découpe, il peut être utile de procéder à une étape optionnelle de traitement de la surface extérieure de la couche 6 de vernis de protection pour améliorer encore le recouvrement ultérieur de l'étiquette par le revêtement 12 de finition. Lors de cette étape, on réalise par exemple un dépoli mécanique ou chimique de la surface du vernis, de manière analogue au dépoli du film support 2. Alternativement ou en combinaison, et préférentiellement après l'étape de découpe, ce traitement peut comprendre un nettoyage de la surface extérieure avec un solvant, par exemple avec de l'alcool isopropylique afin d'éliminer toute trace de contamination de la surface pouvant nuire au recouvrement ultérieur de celle-ci par le revêtement 12 de finition. Ainsi, la face extérieure de la couche 6 de vernis de protection présente un état de surface propre à faciliter l'adhérence du revêtement 12 de finition sur le dispositif de marquage.Before or preferably after cutting, it may be useful to proceed to an optional step of treating the outer surface of the protective varnish layer 6 to further improve the subsequent recovery of the label by the finishing coating 12. During this step, for example, a mechanical or chemical frosting of the surface of the varnish is carried out so that similar to the frosting of the support film 2. Alternatively or in combination, and preferably after the cutting step, this treatment may comprise a cleaning of the outer surface with a solvent, for example with isopropyl alcohol in order to eliminate all traces contamination of the surface may hinder the subsequent recovery thereof by the coating 12 finishing. Thus, the outer face of the protective varnish layer 6 has a clean surface condition to facilitate the adhesion of the finishing coating 12 to the marking device.
Une fois la découpe effectuée, le dispositif de marquage est susceptible d'être utilisé, mais pour faciliter son report à l'endroit exact où il est prévu, il est avantageux d'utiliser un film de manipulation 8 en papier ou en polyéthylène semi transparent par exemple, comportant une couche de colle 7 dont le pouvoir adhésif est supérieur au pouvoir adhésif de la couche 3 d'adhésif sur sa feuille de protection 4 mais très inférieur au pouvoir adhésif de cette même couche d'adhésif sur le substrat 10 ou la peinture 11 sur lesquels le dispositif de marquage doit être collé. Le film de manipulation 8 est alors reporté sur la planche d'étiquettes dans une étape S 105 du procédé de réalisation du dispositif de marquage.Once the cutting is done, the marking device is likely to be used, but to facilitate its transfer to the exact location where it is provided, it is advantageous to use a handling film 8 paper or semi-transparent polyethylene for example, having a layer of adhesive 7 whose adhesiveness is greater than the adhesive strength of the adhesive layer 3 on its protective sheet 4 but much less than the adhesive strength of this same layer of adhesive on the substrate 10 or the paint 11 on which the marking device is to be glued. The handling film 8 is then transferred to the label sheet in a step S 105 of the method for producing the marking device.
Dans une variante du dispositif de marquage selon l'invention, le motif 5 de marquage et la couche 6 de vernis sont remplacés par une couche de peinture directement appliquée sur le film support 2. La couche de peinture est réalisée à partir d'une peinture identique à la peinture 11 utilisée pour recouvrir le substrat 10 (la carlingue de l'avion). Il est ainsi possible d'obtenir des feuilles autocollantes composées d'un « complexe » film support 2 / couche 3 d'adhésif / feuille de protection revêtu d'une couche de peinture d'une teinte identique à celle utilisée pour certaines parties de la carlingue. On peut ainsi réaliser un marquage par découpe d'un motif « positif » dans cette feuille autocollante qui remplace un marquage obtenu par peinture au moyen de la même peinture au travers d'un pochoir découpé selon le même motif en « négatif ». La peinture utilisée sur le film support étant la même que celle appliquée directement sur le substrat, elle sera compatible avec le revêtement 12 appliqué par-dessus. Cette variante du dispositif de marquage selon l'invention permet d'obtenir un marquage sur une première partie d'une surface bicolore contrastée en utilisant une peinture d'une teinte exactement semblable à la couleur de la seconde partie, à la différence des films autoadhésifs colorés dans la masse utilisés actuellement, dont les teintes ne correspondent pas toujours. Dans cette variante également, il est possible de réaliser un décor unique par peinture directe sur une feuille de complexe constitué d'un film support 2 selon l'invention et d'une couche d'adhésif. Un tel décor est en général peint directement par l'artiste sur l'objet à décorer, qu'il s'agisse de la carlingue d'un avion, d'une carrosserie de véhicule, etc. Cette méthode implique l'immobilisation de l'objet pendant le temps de la peinture et de son séchage. Grâce au dispositif de marquage selon l'invention, il est possible de réaliser cette peinture sur le film support, y compris les étapes de séchage et de protection par la couche de vernis 6, puis en un temps réduit, de l'appliquer sur l'objet. Il est ainsi possible de réduire de plusieurs jours à quelques heures le temps d'immobilisation nécessaire pour décorer un avion, ce qui représente un gain économique considérable. In a variant of the marking device according to the invention, the marking pattern 5 and the layer 6 of varnish are replaced by a layer of paint directly applied to the support film 2. The paint layer is made from a paint identical to the paint 11 used to cover the substrate 10 (the cabin of the aircraft). It is thus possible to obtain self-adhesive sheets composed of a "complex" support film 2 / layer 3 of adhesive / protective sheet coated with a layer of paint of a hue identical to that used for certain parts of the cabin. It is thus possible to cut a "positive" pattern in this self-adhesive sheet which replaces a marking obtained by painting with the same paint through a stencil cut in the same "negative" pattern. The paint used on the support film being the same as that applied directly to the substrate, it will be compatible with the coating 12 applied over it. This variant of the marking device according to the invention makes it possible to obtain a marking on a first part of a contrasting two-color surface using a paint of a hue exactly similar to the color of the second part, unlike the self-adhesive color-in-the-art films currently used, whose hues do not always match. In this variant also, it is possible to achieve a unique decoration by direct painting on a complex sheet consisting of a support film 2 according to the invention and an adhesive layer. Such a decoration is usually painted directly by the artist on the object to decorate, whether the cabin of an aircraft, a vehicle body, etc. This method involves the immobilization of the object during the time of painting and its drying. With the marking device according to the invention, it is possible to produce this paint on the support film, including the steps of drying and protection by the varnish layer 6, and then in a reduced time, to apply it on the substrate. 'object. It is thus possible to reduce from several days to a few hours the downtime necessary to decorate an aircraft, which represents a considerable economic gain.
