Abstract

Laminated sandwich composed of a core made of a plant-based medium which may be dyed or printed beforehand, the two polyester faces also being able to include magnetic tracks, protective layers, encoded perforations or photographic, thermal or diazo-compound layers.

Description

L'emploi de films polyester pour la réalisation de nombreuses surfaces convenant à des utilisations très diverses a été soumi ces dernières années à une demande considérable tant ce produit répond à des critères très poussés, notamment en ce qui concerne la stabilité dimensionnelle, la résistance à la traction ou à la déchirure ou encore à la chaleur. The use of polyester films for the production of numerous surfaces suitable for a wide variety of uses has been subjected in recent years to considerable demand as this product meets very advanced criteria, in particular as regards dimensional stability, resistance to tensile or tear or heat.

Ce type de film a ainsi progressivement remplacé des produits plus anciens, moins adaptés aux exigences modernes, tels que les films de poly-acétate de vinyle, les polycarbonates ou autres. This type of film has thus gradually replaced older products, less suited to modern requirements, such as polyvinyl acetate films, polycarbonates or others.

Le prix des films polyester représente toutefois un obstacle à leur plein emploi, mais, ce prix étant lié à l'élaboration assez complexe du produit, il convient de ne pas s'attendre à une baisse sensible dans le futur. The price of polyester films, however, represents an obstacle to their full use, but, this price being linked to the rather complex production of the product, we should not expect a significant drop in the future.

Pour cette raison, on a vu apparaître sur le marché, notamment celui du film à dessin, des variantes consistant à coller sur les deux faces d'un film mince une feuille de papier à dessin. On conservait ainsi la solidité du film polyester, à un moindre coût, mais avec quelques inconvénients en plus. For this reason, variants have appeared on the market, in particular that of drawing film, consisting in gluing a sheet of drawing paper on both sides of a thin film. The strength of the polyester film was thus preserved, at a lower cost, but with a few more disadvantages.

Dans certains cas toutefois, l'emploi du film polyester comme tel se heurte à des difficultés importantes. Tel est notamment le cas lorsque des épaisseurs assez fortes sont exigées. In certain cases, however, the use of the polyester film as such encounters significant difficulties. This is particularly the case when fairly large thicknesses are required.

Il est clair en effet qu'un film polyester de la grosseur d'un carton par exemple, serait difficile à commercialiser : outre son prix prohibitif, sa rigidité et son poids seraient le plus souvent incompatibles avec une utilisation pratique. It is clear, in fact, that a polyester film the size of a carton, for example, would be difficult to market: in addition to its prohibitive price, its rigidity and its weight would most often be incompatible with practical use.

Or la demanderesse a trouvé que des produits, d'une épaisseur moyenne à forte, de papier ou de carton de grammage variant entre 50 g et 1 200 g/m2 peuvent parfaitement être traités de façon à présenter en surface les avantages inhérents au polyester, si on colle sur les deux faces d'un tel support papier ou carton un film polyester d'épaisseur adéquate de 3 à 175 microns. Now, the Applicant has found that products, of medium to heavy thickness, of paper or cardboard of grammage varying between 50 g and 1,200 g / m2 can be perfectly treated so as to present on the surface the advantages inherent in polyester, if a two-ply polyester film of adequate thickness from 3 to 175 microns is bonded to the two sides of such a paper or cardboard support.

Dans ces conditions en effet on obtient un ensemble très résistant pouvant être absolument adapté au but recherché par le choix approprié d'épaisseur du support végétal et de celle du film.  Under these conditions, in fact, a very resistant assembly is obtained which can be absolutely adapted to the aim sought by the appropriate choice of thickness of the plant support and that of the film.

De cette façon en effet, les inconvénients précités du sandwich inverse sont éliminés car les deux surfaces externes sont constituées par le film et en présentent donc tous les avantages. In this way, in fact, the aforementioned drawbacks of the reverse sandwich are eliminated because the two external surfaces are formed by the film and therefore have all the advantages.

La réalisation d'un tel produit se fait par dépôt d'une colle sur une face du support végétal, ce dépôt pouvant être réalisé de façon connue en soi, par pulvérisation ou encore par un cylindre enducteur. Le film polyester est alors appliqué, sur la face ainsi encollée, au moyen d'un rouleau presseur. On répète l'opération de l'autre côté du support et obtient ainsi le produit terminé, qui est enfin embobiné et stocké. The production of such a product is done by depositing an adhesive on one face of the plant support, this deposit being able to be produced in a manner known per se, by spraying or even by a coating cylinder. The polyester film is then applied, on the face thus glued, by means of a pressure roller. The operation is repeated on the other side of the support and thus obtains the finished product, which is finally wound up and stored.

Il convient de remarquer qu'il est très possible d'imprimer le support végétal ou de le colorer avant le contre-collage du film polyester on réalise ainsi des surfaces dont l'écriture, localisée sous la couche de polyester, résistera à toutes les attaques physiques ou chimiques, protégée qu'elle est par le film lui-même. It should be noted that it is very possible to print the plant support or to color it before laminating the polyester film, thus producing surfaces whose writing, located under the polyester layer, will resist all attacks. physical or chemical, protected as it is by the film itself.

Bien entendu la coloration ou l'impression du support végétal peut être réalisée aussi bien sur le recto que sur le verso, les deux faces étant protégées ultérieurement de la même façon. Of course, the coloring or printing of the plant support can be carried out both on the front and on the back, the two faces being subsequently protected in the same way.

Il est possible également d'utiliser un papier aluminisé sur une ou deux faces, ce papier pouvant être imprimé. Dans ce cas, le contre-collage avec le film polyester aboutira à un film d'aspect aluminisé, ce qui est un avantage pour certaines applications. It is also possible to use aluminized paper on one or two sides, this paper being able to be printed. In this case, laminating with the polyester film will result in a film of aluminized appearance, which is an advantage for certain applications.

Le papier aluminisé peut bien entendu être remplacé par un support d'aspect bronzé, doré, cuivré ou autre, suivant les besoins qui se présenteront. The aluminized paper can of course be replaced by a support with a tanned, golden, copper-colored or other appearance, according to the needs which will arise.

Le couchage de ce type de sandwich se fait exactement comme est réaliser l'enduction d'un film polyester simple. The coating of this type of sandwich is done exactly as is the coating of a simple polyester film.

On peut le revêtir d'un simple vernis incolore ou coloré. It can be coated with a simple colorless or colored varnish.

On peut aussi le coucher de façon à réaliser des surfaces imprimables pouvant présenter, en conjonction avec l'impression du support végétal sous-jacent, des effets décoratifs variables. It can also be laid down so as to produce printable surfaces which can exhibit, in conjunction with the printing of the underlying plant support, variable decorative effects.

On peut également déposer une piste magnétique sur l'une, l'autre ou les deux faces du sandwich pour réaliser des systèmes codés. Ces pistes peuvent être recouvertes de couches de protection anti-abrasion ou de protection contre l'humidité , ou encore anti-statique. On peut aussi perforer le sandwich pour réaliser des cartes codées de rigidité variable mais dont les perforations seraient très résistantes à l'usure ou aux déformations.  It is also possible to deposit a magnetic strip on one, the other or both sides of the sandwich to produce coded systems. These tracks can be covered with layers of abrasion protection or protection against humidity, or even anti-static. You can also perforate the sandwich to make coded cards of variable stiffness but whose perforations are very resistant to wear or deformation.

Ces variantes du produit, objet de l'invention, conviennent parfaitement pour les billets de chemin de fer, de métro, de bus, de parking, d'avion, d'expédition de colis, bagages ou autres. These variants of the product which is the subject of the invention are perfectly suited for rail, metro, bus, parking, plane, parcel, luggage or other tickets.

Enfin on peut coucher sur le produit une émulsion photographique aux hologénures d'argent, ou encore une couche à développement thermique, ou encore une émulsion photo-sensible diazolque.  Finally, a photographic emulsion with silver hologenides, or a layer with thermal development, or even a diazolic photo-sensitive emulsion can be coated on the product.
