Abstract

PCT No. PCT/FR94/00054 Sec. 371 Date Jul. 17, 1996 Sec. 102(e) Date Jul. 17, 1996 PCT Filed Jan. 18, 1994 PCT Pub. No. WO95/19268 PCT Pub. Date Jul. 20, 1995A paper type or similar sheet substrate for receiving an image in a printing or reproduction process. The sheet has a number of uniformly distributed holes, providing a paper which is transparent on one side and is capable of being applied to a glass pane. On the outside, the light illuminates the image and limits visibility of the holes; on the inside, the holes let the light through, making the document appear transparent. The transparency effect is advantageously reinforced by the application of a light-absorbing solid black area on the reverse. Depending on the printing or reproduction processed used, the perforated sheet can be associated with an unperforated sheet applied to its reverse side, thereby providing a lining sheet for the perforated sheet.

Description

La présente invention a trait aux domaines généraux de la communication et du papier; elle concerne plus particulièrement un nouveau support en forme de feuille du genre papier ou similaire, destiné à recevoir une information ou un marquage par impression ou par reproduction.The present invention relates to the general fields of communication and paper; it concerns more particularly a new leaf-like medium of its kind paper or similar, intended to receive information or a marking by printing or reproduction.

Dans un document D1: FR-A 2 525 370 demande de brevet n'ayant pas été accordée, concernant un support publicitaire destiné à équiper toutes les surfaces vitrées sans les occulter, notamment celles des véhicules automobiles et particulièrement celles des taxis, il est décrit un support dont la matière est imprimée et ensuite perforée, procédé identique à celui de la fabrication des pare-soleil décoratifs vendus sur le marché. Ensuite, les exemples donnés ne décrivent aucun moyen technique permettart de répondre aux interrogations posées.In a document D1: FR-A 2 525 370 patent application not having been granted, concerning an advertising medium intended to equip all glass surfaces without obscure, in particular those of motor vehicles and particularly those of taxis, it is described a support whose material is printed and then perforated, process identical to the manufacturing of decorative sun visors sold on the market. Then the examples given do not describe no technical means permart to respond to questions asked.

Un document D2: DE-A 28 38 028, décrit un procédé pour l'alimentation de matériaux tissés dans des machines à imprimer en feuille à feuille; ce document concerne uniquement des matériaux tissés. Notre invention concerne un support genre papier ou similaire dont les caractéristiques ne peuvent être assimilées aux matériaux tissés.A document D2: DE-A 28 38 028 describes a process for feeding woven materials into machines sheet-by-sheet printing; this document only concerns woven materials. Our invention relates to a support paper-like or similar, the characteristics of which cannot be assimilated to woven materials.

La présente invention est celle d'un support en forme de feuille genre papier ou similaire pour impression ou reproduction, constitué d'une feuille munie d'une multitude de perforations régulièrement réparties, qui prévoit une partie solidaire non perforée constituant des moyens permettant la prise en charge du support par les système de préhension des matériels d'impression ou de reproduction pour l'obtention d'un papier transparent une face pouvant être utilisé comme un consommable classique par ces dits matériels.The present invention is that of a shaped support of sheet like paper or similar for printing or reproduction, consisting of a leaf provided with a multitude of regularly distributed perforations, which provides a part non-perforated integral constituting means allowing the support supported by the gripping systems printing or reproduction materials for obtaining one side transparent paper that can be used as a classic consumable by these so-called materials.

Le support selon l'invention se présente sous la forme d'une feuille genre papier ou similaire munie d'une multitude
   de perforations régulièrement réparties. Cette feuille perforée est destinée à recevoir un visuel en forme de document informatif, décoratif ou de marquage, par une technique classique de reproduction (reprographie) ou d'impression (offset, sérigraphie ou autre). Une fois marqué sur le recto, ce support constitue un papier transparent une face, susceptible d'être fixé sur une vitre par exemple. Du côté extérieur, le recto de ce papier transparent une face est éclairé par la lumière; le visuel apparaít clairement et on oublie les perforations. Du côté intérieur, les perforations laissent passer la lumière et le document paraít,sensiblement transparent. Cette impression de transparence est avantageusement renforcée en prévoyant un aplat coloré sur le verso (noir de préférence) qui permet l'absorption de la lumière.The support according to the invention is in the form of a paper-like sheet or the like provided with a multitude
regularly distributed perforations. This perforated sheet is intended to receive a visual in the form of an informative, decorative or marking document, by a conventional technique of reproduction (reprography) or printing (offset, serigraphy or other). Once marked on the front, this support constitutes a transparent paper on one side, capable of being fixed on a window for example. On the outside, the front of this one-sided transparent paper is lit by light; the visual appears clearly and we forget the perforations. On the inside, the perforations let in light and the document appears, substantially transparent. This impression of transparency is advantageously reinforced by providing a colored solid on the back (preferably black) which allows the absorption of light.

De façon très surprenante, le choc provoqué par la technique de perforation utilisée, confère à la feuille de papier une plus grande rigidité et une meilleure tenue. En outre, l'utilisation d'une telle technique limite de façon notable les influences d'une variation hygrométrique de l'air sur la planéité du papier, par rapport aux feuilles pleines classiques.Very surprisingly, the shock caused by the perforation technique used, gives the sheet of paper with greater rigidity and better hold. In moreover, the use of such a technique limits in a way notable the influences of a hygrometric variation of the air on the flatness of the paper, compared to the full sheets classics.

Un tel support permet l'obtention d'affiches publicitaires, d'affichettes promotionnelles, de posters ou de pare-soleil par exemple, qui filtrent la lumière et, ainsi, qui ne masquent plus la clarté des surfaces vitrées, côté intérieur.Such a support makes it possible to obtain posters advertising, promotional posters, posters or sun visors for example, which filter the light and, thus, which no longer mask the clarity of the glass surfaces, side interior.

Les perforations de la feuille ont de préférence une surface voisine de 0,8 mm2 et elles sont avantageusement réparties selon une densité de l'ordre de 20 à 30 par cm2, sous la forme d 'une trame régulière.The perforations of the sheet preferably have an area close to 0.8 mm 2 and they are advantageously distributed according to a density of the order of 20 to 30 per cm 2 , in the form of a regular weft.

Selon une autre disposition de l'invention, le support comporte un cadre périphérique non perforé qui permet de renforcer sa structure ; ce cadre plein évite notamment toute déchirure intempestive et toute dégradation accidentelle du matériau.According to another provision of the invention, the support includes a non-perforated peripheral frame which helps strengthen its structure; this full frame avoids in particular any untimely tearing and any degradation accidental material.

Selon une forme de réalisation particulière, la feuille munie de per forat ions comporte une partie non perforée sur une au moins de ses bordures. Cette partie non perforée est disposée de façon adéquate et présente des dimensions telles qu'elle permet la prise en charge de la feuille à l'aide des moyens classiques par dépression du matériel d' impression ou de reproduction. Ces "ventouses aspirantes" se rencontrent notamment sur les margeurs d'introduction des feuilles des machines offset ; elles servent à prélever la feuille que l'on désire imprimer et à la transporter jusqu'aux prises de pinces pour permettre l'impression.According to a particular embodiment, the sheet provided with per forat ion has a part not perforated on at least one of its edges. This part unperforated is adequately arranged and present dimensions such that it supports of the sheet using conventional vacuum means printing or reproduction material. These "suckers aspirantes "meet in particular on the feeders introduction of sheets for offset machines; they are used to remove the sheet that you want to print and transport it to the gripper sockets for allow printing.

Selon une autre disposition de l'invention, la feuille de papier perforée est associée à une seconde feuille pleine qui vient la doubler et qui est appliquée sur son verso. Les deux feuilles ont sensiblement les mêmes dimensions et elles sont solidarisées entre elles par une au moins de leurs bordure s, et ceci par tout moyen approprié tel qu'une ligne de pli ou un collage par ligne ou par points.
Cette feuille pleine est associée à la feuille perforée pour faciliter ou permettre, dans certains cas, en fonction des technologies utilisées, le marquage du visuel sur le recto du support. Une fois le visuel transféré par Impression ou par reproduction, on enlève la feuille pleine de doublage pour obtenir le papier transparent une face.According to another arrangement of the invention, the perforated sheet of paper is associated with a second full sheet which comes to double it and which is applied to its back. The two sheets have substantially the same dimensions and they are joined together by at least one of their edges, and this by any suitable means such as a fold line or a collage by line or by points.
This solid sheet is associated with the perforated sheet to facilitate or allow, in certain cases, depending on the technologies used, the marking of the visual on the front of the support. Once the visual is transferred by Printing or by reproduction, we remove the full sheet of liner to obtain transparent paper on one side.

Dans le domaine de l'offset, cette feuille de doublage permet le transfert du support par succion au travers des perforations.
Dans le cadre de la sérigraphie, elle permet le maintien du support sur la table d'aspiration au cours de l'impression et elle assure également la récupération de l'encre susceptible de passer par les perforations. Pour l'ensemble des machines d'impression, la feuille pleine de doublage facilite la prise et le glissement des supports les uns sur les autres au niveau du margeur. Elle confère au support une surface inférieure lisse sans laquelle on n'obtiendrait pas une bonne distribution en machine. A noter que pour les deux techniques d'impression ( offset et sérigraphie), le surplus d'encre non déposé à l'endroit des perforations à tendance à s'éliminer de lui-même au fur et à mesure du passage des feuilles ; en effet, les perforations ne se présentent pas toujours exactement au même endroit en machine.
Dans le cadre des techniques de reprographie, cette feuille pleine assure la protection du tambour en récupérant les encres qui passent au travers des perforations et en les fixant sur cette feuille au moment du passage en cuisson. De cette manière, les copieurs ne subissent aucun encrassement.In the offset field, this doubling sheet allows the transfer of the support by suction through the perforations.
As part of screen printing, it allows the support to be held on the suction table during printing and it also ensures the recovery of the ink likely to pass through the perforations. For all printing machines, the full liner sheet makes it easier to pick up and slide the supports on top of each other at the feeder. It gives the support a smooth bottom surface without which one would not obtain good machine distribution. Note that for the two printing techniques (offset and screen printing), the excess ink not deposited at the location of the perforations tends to eliminate itself as the sheets pass; indeed, the perforations do not always appear exactly in the same place in the machine.
In the context of reprography techniques, this solid sheet protects the drum by recovering the inks which pass through the perforations and by fixing them on this sheet at the time of passage in cooking. In this way, the copiers are not fouled.

En outre, selon une autre disposition de l'invention, les deux feuilles superposées sont solidarisées entre elles au niveau de l'une de leurs bordures et elles sont reliées ou retenues sur la bordure opposée, de façon telle qu'elles puissent glisser l'une sur l'autre et se déplacer légèrement l'une par rapport à l'autre cette caractéristique assure un enroulement parfait des deux feuilles sur le tambour des copieurs type laser couleur par exemple . La liaison "glissante" peut par exemple être obtenue par un entrecroisement d'encoches droites prévues sur l'une des feuilles et d' encoches obliques prévues sur la seconde.Furthermore, according to another provision of the invention, the two overlapping sheets are joined together at one of their borders and they are connected or retained on the opposite border, so that they can slide over each other and move slightly one in relation to the other this characteristic ensures perfect winding of the two sheets on the drum color laser copiers for example. The link "slippery" can for example be obtained by a intersection of straight notches provided on one of the oblique sheets and notches provided on the second.

Mais l'invention sera encore illustrée, sans être aucunement limitée, par la description suivante de plusieurs modes de réalisation, donnés à titre d'exemples et représentés sur les dessins annexés dans lesquels :

  • la figure 1 est une vue en perspective d'un mode de réalisation possible du support papier selon l'invention, destiné à recevoir un marquage par impression ou par reproduction ;
  • la figure 2 est une vue agrandie d'une portion de ce support ;
  • la figure 3 est une vue en perspective d'une autre forme de réalisation possible du support ;
  • la figure 4 montre un autre exemple de réalisation du support constitué d'une feuille perforée associée à une feuille pleine de doublage ;
  • les figures 5a et 5b montrent les moyens de liaison "glissants" susceptibles d'être prévus pour relier l'un des côtés du doublage de feuilles ;
  • la figure 6 montre, vu de côté, le résultat d'une telle liaison lors de l'enroulement des feuilles superposées sur un tambour de copieur par exemple.
However, the invention will be further illustrated, without being in any way limited, by the following description of several embodiments, given by way of examples and represented in the appended drawings in which:
  • Figure 1 is a perspective view of a possible embodiment of the paper medium according to the invention, for receiving a marking by printing or reproduction;
  • Figure 2 is an enlarged view of a portion of this support;
  • Figure 3 is a perspective view of another possible embodiment of the support;
  • Figure 4 shows another embodiment of the support consisting of a perforated sheet associated with a full sheet of lining;
  • FIGS. 5 a and 5 b show the "sliding" connection means capable of being provided for connecting one of the sides of the lining of sheets;
  • FIG. 6 shows, seen from the side, the result of such a connection during the winding of the superimposed sheets on a copier drum for example.

Tel qu'on l'a représenté sur la figure 1, le support 1 selon l'invention est constitué d'une feuille 2 genre papier ou tout autre matériau "rigide" similaire. L'une des faces de la feuille 2 (le recto) est destinée à être , traitée par impression ou par reproduction pour y appliquer un visuel quelconque, type informatif, décoratif ou publicitaire. Cette feuille de papier peut avoir un format quelconque du genre 60x80, 40x60, 30x40 ou 30x80, par exemple. Son grammage peut être compris entre 80 et 150g/m2 ; il sera de préférence supérieur à 100g/m2 pour l'obtention d'un papier transparent une face de bonne qualité.As shown in Figure 1, the support 1 according to the invention consists of a sheet 2 like paper or other similar "rigid" material. One of the faces of the sheet 2 (the front) is intended to be, processed by printing or by reproduction to apply any visual, informative, decorative or advertising type. This sheet of paper can have any format like 60x80, 40x60, 30x40 or 30x80, for example. Its grammage can be between 80 and 150g / m 2 ; it will preferably be greater than 100 g / m 2 for obtaining a transparent paper with one side of good quality.

La feuille 2 est soumise à un traitement d'emboutissage vertical au moyen de lignes de poinçons pour former une multitude de perforations 3. Les moyens de perforation sont avantageusement associés à un système précis de gestion du défilement du matériau papier. L'opération de poinçonnage confère des propriétés particulières de rigidité et de tenue de l'humidité.Sheet 2 is subject to processing vertical stamping by means of punch lines to form a multitude of perforations 3. The means of perforation are advantageously associated with a system precise management of the scrolling of the paper material. The punching operation confers properties particular rigidity and moisture resistance.

La surface de chaque perforation circulaire est de l'ordre de 0,8 à 1 mm2. Ces perforations sont disposées par rangées décalées d'un demi-pas l'une par rapport à l'autre pour former une trame régulière, de la façon représentée sur la figure 2. Pour obtenir un papier transparent une face de bonne qualité, les perforations 3 sont réparties selon une densité comprise entre 20 et 30 par cm2 et de préférence de l'ordre de 25 par cm2. Les perforations 3 occupent normalement environ le 1/4 de la surface du papier.The surface of each circular perforation is of the order of 0.8 to 1 mm 2 . These perforations are arranged in rows offset by half a step relative to each other to form a regular screen, as shown in Figure 2. To obtain a transparent paper one side of good quality, the perforations 3 are distributed according to a density of between 20 and 30 per cm 2 and preferably of the order of 25 per cm 2 . The perforations 3 normally occupy about 1/4 of the surface of the paper.

On remarque sur les figures 1 et 2, la présence d'un cadre 4 dépourvu de perforations, qui entoure la zone perforée 5. Ce cadre non perforé 4 permet de renforcer la structure de la feuille 2 ; il limite les déchirements intempestifs ou accidentels liés à la trame de perforations et permet en outre la prise de pinces.We note in Figures 1 and 2, the presence a frame 4 devoid of perforations, which surrounds the area perforated 5. This non-perforated frame 4 makes it possible to reinforce the structure of sheet 2; it limits tears accidental or accidental linked to the pattern of perforations and also allows gripping pliers.

Le recto de la feuille 2 a de préférence une coloration neutre, blanche par exemple ; elle peut également être teintée en fonction du visuel désiré. Son verso est recouvert d'un aplat de couleur sombre, noir de préférence, qui permet une absorption optimale de la lumière et qui optimise la transparence de ce côté du support.The front of sheet 2 preferably has a neutral coloring, white for example; she can also be tinted according to the desired visual. Its back is covered with a dark solid color, preferably black, which allows optimal absorption of light and which optimizes transparency on this side of the support.

On a représenté sur la figure 3 un support 1 selon l'invention susceptible d'être utilisé pour une impression en offset. Ce support 1 est constitué d'une feuille 2 munie d une zone de perforations 5, schématisée par l'encadrement barré, laquelle zone perforée 5 est entourée par un cadre 4 non perforé. Sur l'un de ses côtés, le cadre 4 présente une largeur a plus importante. La partie correspondante 6, dépourvue de perforations, est située dans la zone qui correspond à l'endroit de prise en charge de la feuille par les moyens d'aspiration du système de transfert du matériel.
Une feuille perforée de ce type peut être utilisée telle quelle pour l'impression. L'encre du rouleau d'impression qui ne se dépose pas sur le support, au niveau des perforations, s'élimine d'elle-même lors du passage des feuilles suivantes car, du fait de la grosseur des espacements de la trame de perforations, les trous ne se présentent pas toujours au même endroit en machine.FIG. 3 shows a support 1 according to the invention capable of being used for offset printing. This support 1 consists of a sheet 2 provided with a perforation zone 5, shown diagrammatically by the barred frame, which perforated zone 5 is surrounded by a non-perforated frame 4. On one of its sides, the frame 4 has a width more important. The corresponding part 6, devoid of perforations, is located in the zone which corresponds to the place where the sheet is taken up by the suction means of the material transfer system.
A perforated sheet of this type can be used as is for printing. The ink of the printing roller which does not deposit on the support, at the level of the perforations, eliminates itself during the passage of the following sheets because, because of the size of the spacings of the screen of perforations , the holes do not always appear in the same place in the machine.

Comme on l'a représenté sur la figure 4, le support 1 selon l'invention peut être constitué d'une feuille perforée 2, du même type que celle représentée sur la figure 1, associée à une feuille pleine 7 servant de doublage et appliquée sur son verso.
La feuille 7 de doublage est solidarisée avec la feuille 2 perforée de façon à pouvoir être aisément enlevée après le transfert du visuel. Sur la figure 4, la feuille pleine 7 est représentée légérement en retrait sous la feuille perforée 2. Cette représentation a pour seul but de bien montrer la structure du support 1 ; dans la réalité et lors de son utilisation, les deux feuilles 2 et 7 sont plaquées l'une sur l'autre sur toute leur surface de façon à obtenir deux couches de matière superposées.As shown in FIG. 4, the support 1 according to the invention may consist of a perforated sheet 2, of the same type as that shown in FIG. 1, associated with a solid sheet 7 serving as a lining and applied on its back.
The doubling sheet 7 is secured to the perforated sheet 2 so that it can be easily removed after the transfer of the visual. In FIG. 4, the solid sheet 7 is shown slightly recessed under the perforated sheet 2. This representation has the sole purpose of clearly showing the structure of the support 1; in reality and during its use, the two sheets 2 and 7 are pressed one over the other over their entire surface so as to obtain two superimposed layers of material.

Les deux feuilles 2 et 7 ont les mêmes dimensions et elles sont solidarisées entre elles par au moins une de leurs bordures.
Selon une forme de réalisation possible, elles ont une nature identique et le support 1 est obtenu à partir d'une feuille papier unique (grammage : 135g/m2 par exemple) pliée en son milieu. Dans ce cas, les moyens de solidarisation 8 des deux feuilles 2 et 7 se situent sur une seule de leurs bordures et consistent en une simple ligne de pli. Seule une partie de la feuille de base subit un traitement de perforation et l'apposition d'un à-plat coloré sur son verso.
Dans une autre forme de réalisation, la feuille pleine de doublage 7 peut également être rapportée et solidarisée par des lignes ou des points de colle sur une ou plusieurs bordures de la feuille perforée 2. Le doublage 7 peut alors avoir une nature et en particulier un grammage différent de celui de la feuille perforée 2.The two sheets 2 and 7 have the same dimensions and they are joined together by at least one of their edges.
According to a possible embodiment, they have an identical nature and the support 1 is obtained from a single paper sheet (grammage: 135 g / m 2 for example) folded in the middle. In this case, the securing means 8 of the two sheets 2 and 7 are located on only one of their edges and consist of a single fold line. Only part of the base sheet undergoes a perforation treatment and the affixing of a colored flat on its back.
In another embodiment, the solid liner sheet 7 can also be attached and secured by lines or dots of glue on one or more edges of the perforated sheet 2. The liner 7 can then have a nature and in particular a different grammage from that of the perforated sheet 2.

Le complexe feuille perforée-feuille pleine obtenu peut être utilisé dans un matériel d'impression par offset ou par sérigraphie. Pour la sérigraphie, le doublage 7 permet de récupérer l'encre qui passerait par les perforations et il assure également le maintien du support sur la machine, pendant l'impression. Pour ces deux techniques, la feuille pleine est également destinée à permettre le transport des feuilles par succion au travers des perforations. En outre, elle confère au support une surface inférieure lisse qui facilite son glissement et sa séparation de la pile stockée en attente d'impression. The perforated sheet-full sheet complex obtained can be used in offset printing equipment or by screen printing. For screen printing, doubling 7 allows you to recover the ink that would pass through perforations and it also maintains the support on the machine, during printing. For these two techniques, the full sheet is also intended for allow the leaves to be transported by suction through perforations. In addition, it gives the support a smooth bottom surface which facilitates its sliding and its separation from the stored battery awaiting printing.

La technique de reproduction par reprographie, pour certains types de copieurs, et notamment les copieurs laser couleur, nécessite l'enroulement du papier sur une partie de la surface extérieure du tambour. L'obtention d'une copie de qualité passe par un transfert correct de polarité et une bonne cuisson. Cependant, ces caractéristiques ne sont pas faciles à obtenir pour des supports épais constitués de deux feuilles superposées, du fait de l'inhomogénéité de la structure et de la nécessité de prévoir un système de solidarisation aisément destructible. En effet, si les deux feuilles sont solidarisées par un seul de leurs côtés, leur poids entraíne leur séparation sur le côté opposé. D'autre part, si elles sont solidarisées sur l'intégralité de leur périphérie, l'enroulement du papier sur le tambour entraíne un gondolage de la feuille intérieure.The technique of reproduction by reprography, for certain types of copiers, including laser copiers color, requires wrapping paper over part from the outside surface of the drum. Obtaining a quality copying requires correct polarity transfer and good cooking. However, these features do not are not easy to obtain for thick substrates made up of two superimposed sheets, due to the inhomogeneity of the structure and the need to provide an easily destructible joining system. Indeed, if the two sheets are joined by a alone on their sides, their weight leads to their separation on the opposite side. On the other hand, if they are united over their entire periphery, the winding of the paper on the drum causes the sheet to curl interior.

Pour pallier à cet inconvénient, et tel qu'on l'a représenté sur les figures 5a, 5b et 6, on a prévu de solidariser la feuille perforée 2 et la feuille de doublage 7 sur leur bordure d'introduction 9, et ceci par tout moyen approprié du type ligne de pli ou collage, et de les relier ou de les retenir sur leur bordure opposée 10, d'une façon telle que les deux feuilles 2 et 7 puissent glisser parfaitement l'une sur l'autre. Les deux feuilles superposées sont ainsi en permanence plaquées l'une contre l'autre mais elles conservent une possibilité de déplacement léger l'une par rapport à l'autre qui absorbe les effets de courbure.
La figure 6 montre la position du complexe de feuilles sur un rouleau 11 du type tambour de copieur. On remarque le léger déplacement ou décalage 12 inhérent à la courbure, au niveau de la liaison glissante des feuilles.
Ce type de liaison peut être obtenu par tout moyen approprié et en particulier, tel qu'on l'a représenté sur les figures 5a et 5b, au moyen d'encoches droites 13 sur l'une des feuilles 2, associées à des encoches obliques 14 sur la seconde feuille 7. Les découpes correspondantes sont engagées les unes dans les autres et entrecroisées par des moyens mécaniques adaptés, en forme de cylindre muni d'ergots par exemple.To overcome this drawback, and as shown in FIGS. 5 a , 5 b and 6, provision has been made to secure the perforated sheet 2 and the backing sheet 7 on their insertion edge 9, and this by any suitable means of the fold line or gluing type, and connecting or retaining them on their opposite border 10, in such a way that the two sheets 2 and 7 can slide perfectly over one another. The two superimposed sheets are thus permanently pressed against each other but they retain a possibility of slight displacement relative to each other which absorbs the effects of curvature.
FIG. 6 shows the position of the sheet complex on a roller 11 of the copier drum type. Note the slight displacement or offset 12 inherent in the curvature, at the sliding connection of the sheets.
This type of connection can be obtained by any suitable means and in particular, as shown in FIGS. 5 a and 5 b , by means of straight notches 13 on one of the sheets 2, associated with oblique notches 14 on the second sheet 7. The corresponding cutouts are engaged one inside the other and interlaced by suitable mechanical means, in the form of a cylinder provided with lugs for example.

Ce type de liaison peut être obtenu également par rabattement à l'aide d'un pli de l'extrémité de l'une des deux feuilles sur la seconde feuille sur toute sa largeur, ou des deux feuilles ensemble, ou simplement par rabattement de leurs deux coins opposés de la même largeur par un pli à 45° sur une longueur de 10 à 20mm.This type of connection can also be obtained by folding back using a fold of the end of one of the two sheets on the second sheet across its width, or two sheets together, or simply by folding of their two opposite corners of the same width by a fold at 45 ° over a length of 10 to 20mm.

Tout comme pour la technique de sérigraphie, la feuille 7 de doublage prévue sur le support utilisé en reprographie permet de récupérer les encres qui passent au travers des perforations. Ces encres sont fixées sur le doublage au moment du passage en cuisson et le copieur ne subit ainsi aucun encrasserment.As with the screen printing technique, the doubling sheet 7 provided on the support used in reprography makes it possible to recover the inks which pass through the perforations. These inks are fixed on the doubling at the time of passage in cooking and the copier thus does not undergo any fouling.

La nature du support, sa structure et son format sont choisis en fonction du type d'impression ou de reproduction que l'on désire utiliser. Dans tous les cas, après transfert du visuel sur le support, ce dernier peut être appliqué sur une surface vitrée quelconque pour devenir visible de l'extérieur tout en lui conférant une transparence, côté intérieur, permettant de voir à l'extérieur.The nature of the support, its structure and format are chosen according to the type of printing or reproduction that we want to use. In all cases, after transfer of the visual on the support, the latter can be applied to any glass surface to become visible from the outside while giving it a transparency, interior side, allowing to see outside.

Les signes de référence insérés après les caractéristiques techniques mentionnées dans les revendications ont pour seul but de faciliter la compréhention de ces dernières et n'en limitent aucunement la portée.The reference signs inserted after the technical characteristics mentioned in the claims are intended only to facilitate the understanding of these and in no way limit them the scope.
