Description

PROCEDE DE FABRICATION D'UNE PLAQUE SIGNALETIQUE,
NOTAMMENT POUR L'IMMATRICULATION DES VEHICULES AUTOMOBILES
ET PLAQUE AINSI OBTENUE.PROCESS FOR MANUFACTURING A SIGN PLATE,
IN PARTICULAR FOR THE REGISTRATION OF MOTOR VEHICLES
AND PLATE THUS OBTAINED.

La présente invention concerne les plaques signalétiques, notamment pour l'immatriculation des véhicules automobiles et en particulier une plaque signalétique ayant un bel aspect de surface et obtenue de façon économique à partir de l'outillage existant chez les fabricants de plaques minéralogiques en France. The present invention relates to nameplates, in particular for the registration of motor vehicles and in particular a nameplate having a good surface appearance and obtained economically from the tools existing at the manufacturers of number plates in France.

On connaît par le brevet français nO 2 573 004 un procédé de fabrication de plaques de signalisation qui consiste à former par poinçonnage des caractères en relief sur une plaque épaisse de façade en matière transparente et malléable, ceci à partir d'une plaque intermédiaire mince et colorée, dont les parties de caractère colorées poinçonnées sont insérées à l'arrière de la plaque de façade et les parties non insérées sont retirées, et d'une feuille postérieure assemblée (collée), de couleur formant fond ou contraste avec les caractères insérés.Il faut préciser qu'on ne peut employer une plaque rigide postérieure portant la couleur de fond car à ce moment le recouvrement ou contact inévitablement imparfait des surfaces de la plaque transparente épaisse et donc relativement rigide et de la plaque postérieure rigide conduirait à un mauvais rendu de la couleur de fond des caractères (aspect de traces). Il faut donc pour obtenir un fond convenable pour les caractères réaliser un effet de peau recouvrant de façon bien homogène la surface de la plaque transparente du côté de ses caractères insérés et utiliser par exemple un film adhésif coloré bien appliqué tel que précisé dans le brevet susmentionné.Une telle plaque de signalisation présente naturellement un bel aspect de surface en raison de la plaque de façade transparente, mais l'utilisation de matière plastique pour cette plaque épaisse support, inévitable pour la transparence, conduit après poinçonnage à la déformation de cette dernière (forme concave) qui s'accentue dans le temps. Une telle déformation est inacceptable sur le plan esthétique et pratique. L'invention vise à remédier à cet inconvénient. French patent No. 2,573,004 discloses a process for manufacturing signaling plates which consists in punching embossed characters on a thick front plate of transparent and malleable material, this from a thin intermediate plate and colored, of which the stamped colored character parts are inserted at the rear of the front plate and the non-inserted parts are removed, and from an assembled poster sheet (glued), in color forming a background or contrast with the characters inserted. It should be noted that a rigid posterior plate bearing the background color cannot be used because at this time the inevitably imperfect covering or contact of the surfaces of the thick transparent plate and therefore relatively rigid and of the rigid posterior plate would lead to poor rendering. the background color of the characters (appearance of traces). To obtain a background suitable for the characters, therefore, it is necessary to achieve a skin effect covering the surface of the transparent plate very evenly on the side of its inserted characters and for example using a well-applied colored adhesive film as specified in the aforementioned patent. .Such a sign plate naturally has a nice surface appearance due to the transparent front plate, but the use of plastic for this thick support plate, inevitable for transparency, leads after punching to the deformation of the latter ( concave shape) which increases over time. Such deformation is unacceptable from an aesthetic and practical point of view. The invention aims to remedy this drawback.

I1 est en effet proposé selon l'invention un procédé de fabrication de plaques signalétiques, notamment pour l'immatriculation des véhicules automobiles, du type consistant
- à superposer une plaque supérieure ou plaque de façade épaisse et transparente, en matériau relativement malléable, et une plaque intermédiaire plus mince et de couleur
- à placer ces deux plaques ainsi superposées entre un poinçon et une matrice portant les caractères que l'on désire mettre en relief sur la plaque de signalisation, le poinçon étant situé du côté de la plaque intermédiaire de couleur et la matrice du côté de la plaque transparente,
- à presser le poinçon et la matrice en direction l'un de l'autre de manière à découper et enfoncer la plaque intermédiaire suivant le périmètre des caractères portés en relief par le poinçon et à enfoncer dans les empreintes de la matrice les parties correspondantes de la plaque de façade, sans les découper de cette plaque,
- à retirer les parties de la plaque intermédiaire non insérées dans la plaque de façade,
- et à appliquer contre la face postérieure libre de la plaque intermédiaire, une feuille souple (ou film adhésif) postérieure qui lui est fixée par collage, soudage, ou de toute autre matière appropriée, et qui est d'une couleur différente de celle de la face antérieure de la plaque intermédiaire, caractérisé en ce que l'on assemble une plaque rigide, par exemple en aluminium, sur la face postérieure de l'ensemble formé par la plaque transparente poinçonnée avec ses caractères et la feuille souple postérieure.I1 is indeed proposed according to the invention a method of manufacturing nameplates, in particular for the registration of motor vehicles, of the type consisting
- to superimpose a thick and transparent upper plate or facade plate, of relatively malleable material, and a thinner and colored intermediate plate
- to place these two plates thus superimposed between a punch and a matrix bearing the characters which one wishes to highlight on the sign plate, the punch being located on the side of the intermediate colored plate and the matrix on the side of the transparent plate,
- pressing the punch and the die in the direction of one another so as to cut and push the intermediate plate along the perimeter of the characters raised in relief by the punch and to push the corresponding parts of the die into the imprints of the die the front plate, without cutting them from this plate,
- remove the parts of the intermediate plate not inserted in the front plate,
- And to be applied against the free rear face of the intermediate plate, a flexible posterior sheet (or adhesive film) which is fixed to it by gluing, welding, or any other suitable material, and which is of a different color from that of the front face of the intermediate plate, characterized in that a rigid plate, for example aluminum, is assembled on the rear face of the assembly formed by the transparent plate marked with its characters and the posterior flexible sheet.

Ledit assemblage est avantageusement assuré par collage de ladite plaque rigide sur ledit ensemble numéroté et de préférence par passage des plaques entre deux rouleaux laminateurs convenablement écartés l'un de l'autre. Le rouleau du côté des caractères en relief de la plaque de façade transparente est en matière souple. Said assembly is advantageously ensured by bonding said rigid plate to said numbered assembly and preferably by passing the plates between two laminating rollers suitably spaced from one another. The roller on the embossed side of the transparent front plate is made of flexible material.

La feuille postérieure peut aussi être revêtue d'un adhésif permanent sur sa face arrière, adhésif protégé par papier qutil suffit d'enlever avant collage, l'assemblage se faisant également par rouleaux laminateurs. The rear sheet can also be coated with a permanent adhesive on its rear face, adhesive protected by paper which it suffices to remove before bonding, the assembly also being carried out by laminating rollers.

L'invention concerne également une plaque signalétique obtenue par la mise en oeuvre du procédé défini ci-dessus. The invention also relates to a nameplate obtained by the implementation of the method defined above.

L'invention est illustrée ci-après à l'aide d'un exemple de réalisation et en référence au dessin annexé sur lequel
La figure 1 est une vue en coupe transversale d'une plaque signalétique selon l'invention, et
La figure 2 est une vue en coupe longitudinale schématique de la plaque selon l'invention montrant l'assemblage par rouleaux laminateurs.The invention is illustrated below using an embodiment and with reference to the accompanying drawing in which
FIG. 1 is a cross-sectional view of a nameplate according to the invention, and
Figure 2 is a schematic longitudinal sectional view of the plate according to the invention showing the assembly by laminating rollers.

Comme représenté sur les figures, une plaque signalétique selon l'invention s'obtint par collage d'une plaque rigide en aluminium i d'épaisseur 1,0 à 2 mm sur la face postérieure d'un ensemble 2 du type décrit dans le brevet français nO 2 573 004. Cet ensemble comprend de façon connue une plaque transparente épaisse avant 3 comportant en son sein des caractères 4 insérés par poinçonnage à l'arrière d'une plaque intermédiaire, et une feuille postérieure 5 souple colorée recouvrant ladite plaque transparente et dont la couleur détermine le fond par rapport auquel les caractères se détachent. As shown in the figures, a nameplate according to the invention is obtained by bonding a rigid aluminum plate i of thickness 1.0 to 2 mm on the rear face of an assembly 2 of the type described in the patent French No. 2,573,004. This assembly comprises, in a known manner, a thick transparent front plate 3 comprising within it characters 4 inserted by punching at the rear of an intermediate plate, and a flexible colored rear sheet 5 covering said transparent plate and whose color determines the background from which the characters stand out.

La plaque d'aluminium 1 comporte sur l'une de ses faces un adhésif permanent 6 protégé par papier qu'il suffit d'enlever avant l'assemblage. The aluminum plate 1 has on one of its faces a permanent adhesive 6 protected by paper which it suffices to remove before assembly.

Cet assemblage par collage est obtenu par passage de l'ensemble plaque rigide 1 et ensemble 2 entre deux rouleaux laminateurs 7, 7' convenablement écartés l'un de l'autre (figure 2). Le rouleau 7 du côté des caractères en relief est en matière souple. This bonding assembly is obtained by passing the rigid plate assembly 1 and assembly 2 between two laminating rollers 7, 7 'suitably spaced from one another (FIG. 2). The roller 7 on the side of the raised characters is made of flexible material.

La plaque signalétique ainsi obtenue est parfaitement rigide et la plaque d'aluminium arrière résiste à la déformation de poinçonnement de la plaque épaisse transparente de façade en matière plastique. Cette plaque convient maintenant à l'usage d'immatriculation des véhicules.  The nameplate thus obtained is perfectly rigid and the rear aluminum plate resists the punching deformation of the thick transparent plastic front plate. This plate is now suitable for vehicle registration use.
