Description

Procédé d'obtention de chaînon de motifs, et objet, no¬ tamment bijou, comportant un chaînon de motifs Process for obtaining a link of motifs, and object, in particular jewel, comprising a link of patterns
L'invention concerne un procédé d'obtention d'un chaînon de motifs, et un objet, notamment un bijou, com¬ portant un chaînon de motifs.The invention relates to a method for obtaining a link of patterns, and an object, in particular a jewel, com¬ carrying a link pattern.
Par chaînon de motifs, on entend ici un objet en une seule pièce constitué par des motifs accolés, les mo¬ tifs étant creusés sur toute leur épaisseur aux endroits dictés par leur dessin. La résistance structurale du chaînon est donnée par la liaison entre les motifs acco¬ lés. Il ne s'agit pas ici d'une simple gravure de motifs sur une plaque.By pattern link, here means an object in one piece consisting of joined patterns, the mo¬ tifs being hollowed over their entire thickness in the places dictated by their design. The structural strength of the link is given by the connection between the acco¬ les motifs. This is not a simple engraving of motifs on a plate.
Par motif, on entend ici tout dessin de type al- phanumérigue ou non pouvant faire l'objet d'une représen¬ tation en relief avec des pleins et des creux.By reason, is meant here any alphanumeric or non-type design that can be the subject of a relief representation with reliefs and valleys.
ARRIERE-PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION
On connaît des bijoux faits d'un chaînon de mo¬ tifs comme par exemple les gourmettes comportant une suite de caractères alphabétiques accolés représentant un prénom. Ces chaînons sont usinés à partir d'une plaque de métal, ou moulés.Jewelery made of a chain of mo¬ tifs are known, for example bracelets containing a sequence of adjoining alphabetic characters representing a first name. These links are machined from a metal plate, or molded.
L'invention s'intéresse plus particulièrement aux chaînons de motifs de petite taille (de l'ordre de quel- ques millimètres) . Pour de si petites tailles, l'usinage des chaînons de motifs se révèle très difficile. En ou¬ tre, le moulage de motifs aussi fins à la cire perdue est impossible.The invention is more particularly concerned with the links of small patterns (of the order of a few millimeters). For such small sizes, the machining of motif links is very difficult. In addition, the molding of patterns as thin as lost wax is impossible.
OBJET .DE L'INVENTION L'invention a pour objet un procédé d'obtention de chaînons de motifs pouvant être mis en œuvre de façon très économique et pouvant servir à la production de n'importe quel chaînon de motifs.OBJECT OF THE INVENTION The subject of the invention is a process for obtaining chain links that can be implemented in a very economical manner and that can be used for the production of any chain of patterns.
L'invention concerne également un objet, notam- ment un bijou, comprenant un chaînon de motifs. BREVE DESCRIPTION DE L'INVENTIONThe invention also relates to an object, in particular a jewel, comprising a link of patterns. BRIEF DESCRIPTION OF THE INVENTION
En vue de la réalisation de ce but, on propose selon l'invention un procédé d'obtention d'un chaînon de motifs comportant les étapes de: - creuser dans un massif une empreinte comprenant une suite de motifs accolés les uns aux autres;With a view to achieving this object, the invention proposes a process for obtaining a chain of patterns comprising the steps of: digging into a solid mass an imprint comprising a series of patterns contiguous to one another;
- faire pénétrer dans l'empreinte du massif un matériau de prise d'empreinte pour obtenir une suite de motifs en relief; - rigidifier la suite de motifs pour obtenir une forme mâle apte à être moulée ;- to penetrate into the footprint of the massif an impression material to obtain a series of patterns in relief; stiffening the pattern sequence to obtain a moldable male shape;
- réaliser un moulage de la forme mâle.- Make a molding of the male form.
La forme mâle ainsi rigidifiée est ainsi rendue facilement manipulable. La rigidification de la suite de motifs rend possible le moulage de la suite de motifs, notamment à la cire perdue. On peut alors réaliser des chaînons de motifs en métal de très faible hauteur.The male form thus stiffened is thus made easily manipulable. The rigidification of the sequence of patterns makes it possible to mold the pattern suite, including lost wax. It is then possible to make metal pattern links of very low height.
Selon un premier mode de mise en œuvre du procédé de l'invention, l'étape de rigidification comporte l'opé- ration d'associer une semelle à la suite de motifs (11) de sorte que celle-ci forme avec la semelle une forme mâle dans laquelle la suite de motifs s'étend en relief de la semelle.According to a first embodiment of the method of the invention, the step of stiffening comprises the operation of associating a sole after the patterns (11) so that it forms with the sole a male shape in which the pattern suite extends in relief of the sole.
Ainsi, la semelle rigidifie la suite de motifs de la forme mâle. En outre, la semelle facilite l'injection de matière liquide dans le moule formé autour de la forme mâle en offrant la possibilité de prévoir un ou plusieurs points d'alimentation au niveau de la semelle.Thus, the sole stiffens the pattern sequence of the male form. In addition, the sole facilitates the injection of liquid material in the mold formed around the male shape by providing the possibility of providing one or more feed points at the sole.
Selon un aspect particulier de l'invention, le moulage de la forme mâle conduit à un chaînon de motifs s 'étendant en relief d'une base, la base étant au moins partiellement arasée. Ainsi on peut, une fois le moulage effectué, obtenir un chaînon de motifs ne comportant qu'un voile, voire pas de voile du tout si la base est complètement éliminée, ce qui donne d'intéressants effets esthétiques, puisque le chaînon de motifs ainsi obtenu présente une alternance de pleins et de creux.According to a particular aspect of the invention, the molding of the male form leads to a link of patterns extending in relief from a base, the base being at least partially leveled. Thus one can, once the molding done, get a link of patterns with only one veil, or no veil at all if the base is completely eliminated, which gives interesting effects aesthetic, since the link pattern thus obtained has an alternation of full and hollow.
Selon un deuxième mode de mise en œuvre du procé¬ dé de l'invention, le matériau de prise d'empreinte est choisi pour fournir une suite de motifs déformable et l'étape de rigidification comprend l'opération de défor¬ mer la suite de motifs pour faire venir en regard des bords de la suite de motifs et solidariser ces bords en¬ tre eux. La suite de motifs ainsi travaillée forme alors une forme mâle rigide qui peut être facilement moulée.According to a second embodiment of the method of the invention, the impression material is chosen to provide a series of deformable patterns and the stiffening step comprises the defor¬ mer operation following the patterns to come next to the edges of the sequence of patterns and join these edges en¬ them. The result pattern thus worked forms a rigid male shape that can be easily molded.
De préférence, la déformation comprend l'opéra¬ tion d'enrouler la suite de motifs en spirale jointive, les bords en regard étant solidarisés entre eux. BREVE DESCRIPTION DES DESSINSPreferably, the deformation comprises the oper¬ tion of winding the sequence of spiral contiguous patterns, the facing edges being secured to each other.

DESCRIPTION DETAILLEE DE L'INVENTIONFIG. 12 is a perspective view of the male shape obtained by means of the wound pattern sequence of FIG. 11. DETAILED DESCRIPTION OF THE INVENTION
En référence à la figure 1, et selon un premier mode particulier de mise en œuvre, le procédé de l'invention comporte l'étape de creuser une empreinte 2 dans un massif, ici une plaque 1 découpée dans une feuille d'acétate de 2 millimètres d'épaisseur. La plaque 1 a une largeur de 8 millimètres environ.Referring to Figure 1, and according to a first particular embodiment, the method of the invention comprises the step of digging a footprint 2 in a solid mass, here a plate 1 cut in an acetate sheet of 2 millimeters thick. The plate 1 has a width of about 8 millimeters.
L'empreinte 2 comporte une suite de motifs alpha¬ bétiques qui sont accolés les uns aux autres de façon à se chevaucher légèrement. La suite de motifs est obtenue par gravage de la plaque 1 au moyen d'un outil de gravage 3 (ici une fraise à bout sphérique d'un diamètre de 0,6 millimètres) déplacé par un ordinateur 100 sur lequel un programme permet de générer le trajet de l'outil de gra¬ vage 3 à partir d'une suite de motifs, ici des lettres tapées au clavier de l'ordinateur 100. Ici, les motifs ont une hauteur de 3 millimètres.The impression 2 comprises a series of alpha¬ betic patterns which are joined to each other so as to overlap slightly. The sequence of patterns is obtained by etching the plate 1 by means of an etching tool 3 (here a ball-end mill with a diameter of 0.6 millimeters) moved by a computer 100 on which a program can generate the path of the gra¬ vage tool 3 from a series of patterns, here letters typed on the keyboard of the computer 100. Here, the patterns have a height of 3 millimeters.
Puis, comme cela est visible à la figure 2, on positionne la plaque 1 dans un gabarit 4 présentant un creux 5 plus profond que l'épaisseur de la plaque 1. On enduit l'empreinte de la plaque 1 d'un produit l'Then, as can be seen in FIG. 2, the plate 1 is positioned in a jig 4 having a hollow 5 which is deeper than the thickness of the plate 1. The imprint of the plate 1 is coated with a product the
de démoulage, par exemple une huile siliconée.demolding, for example a silicone oil.
Puis on applique sur la plaque 1 une bande de cire 6, par exemple de la cire utilisée dans la fabrica¬ tion de prothèses dentaires, qui a été précédemment ra- mollie par un chauffage léger.Then a wax strip 6 is applied to the plate 1, for example wax used in the manufacture of dental prostheses, which has previously been softened by light heating.
On notera que la bande de cire 6 a une épaisseur telle qu'elle dépasse de la surface supérieure du gabarit 4.It will be noted that the wax strip 6 has a thickness such that it exceeds the upper surface of the jig 4.
Comme cela est visible à la figure- 3, on recouvre cette bande de cire 6 d'une feuille de papier 7, puis on presse la bande de cire 6 dans l'empreinte 2, par exemple en faisant rouler sur la surface supérieure du gabarit 2 un cylindre 8.As can be seen in FIG. 3, this wax strip 6 is covered with a sheet of paper 7, then the wax strip 6 is pressed into the cavity 2, for example by rolling on the upper surface of the template. 2 a cylinder 8.
La cire 6 pénètre alors dans l'empreinte 2, tout en formant une semelle délimitée en épaisseur par la sur¬ face supérieure de la plaque 1 et la surface supérieure du gabarit 4 sur laquelle le cylindre 8 roule. A cet égard, les flancs 9 du creux 5 (visibles à la figure 2) forment un moule pour ladite semelle. Comme cela est visible à la figure 4, l'opération précédente a permis d'obtenir une forme mâle 10 en cire comportant une suite de motifs 11 en relief s'étendant en saillie d'une semelle 12. La feuille 7 a adhéré à la se¬ melle 12 lors de l'opération de pressage, ce qui permet l'extraction aisée de la forme mâle 10 du gabarit 4. Il suffit alors de peler la feuille de papier 7 pour séparer celle-ci de la forme mâle 10, comme illustré.The wax 6 then enters the cavity 2, while forming a sole delimited in thickness by the upper surface of the plate 1 and the upper surface of the jig 4 on which the cylinder 8 rolls. In this respect, the flanks 9 of the recess 5 (visible in FIG. 2) form a mold for said soleplate. As can be seen in FIG. 4, the preceding operation made it possible to obtain a male form 10 made of wax comprising a series of patterns 11 in relief projecting from a sole 12. The sheet 7 adhered to the se¬ melle 12 during the pressing operation, which allows the easy extraction of the male form 10 of the template 4. It is then sufficient to peel the sheet of paper 7 to separate it from the male form 10, as illustrated.
La forme mâle ainsi obtenue est suffisamment ri¬ gide pour pouvoir être facilement manipulée et moulée. Puis, de façon connue en soi, on réalise un mou¬ lage de la forme mâle 10 ainsi obtenue, de préférence par la technique de moulage à la cire perdue. Le matériau utilisé pour le moulage pourra par exemple être de argent, ou encore de 1Or. La semelle 12 réserve dans le moule un espace qui permet d'aménager plusieurs points d'alimentation, faci¬ litant grandement le moulage de motifs aussi petits.The male shape thus obtained is sufficiently ri¬ gide to be easily manipulated and molded. Then, in a manner known per se, the male form thus obtained is molded, preferably by the lost-wax molding technique. The material used for the molding may for example be silver, or 1Or. The sole 12 reserves in the mold a space that allows to arrange several feeding points, faci¬ greatly reading the molding of such small reasons.
On obtient ainsi un moulage d'une apparence en tous points semblable à la forme mâle 10, donc comportant une base 16 (représentée en pointillés à la figure 5) de laquelle un chaînon de motifs 15 s'étend en relief.This produces a molding of an appearance in all respects similar to the male form 10, thus having a base 16 (shown in dashed lines in Figure 5) of which a patterned link 15 extends in relief.
Ici, pour obtenir une finition particulièrement esthétique, la base 16 a été arasée, par exemple par fraisage, en ne laissant subsister que le-chaînon de mo- tifs 15 formant une alternance de creux et de pleins.Here, in order to obtain a particularly aesthetic finish, the base 16 has been leveled, for example by milling, leaving only the link of patterns 15 forming an alternation of valleys and solids.
Ce chaînon de motifs peut être utilisé tel quel, par exemple pour réaliser des bijoux. Néanmoins, en rai¬ son de sa petite taille, il est relativement fragile. Il est alors intéressant de rigidifier un tel chaînon de mo- tifs.This link pattern can be used as is, for example to make jewelry. Nevertheless, because of its small size, it is relatively fragile. It is then interesting to stiffen such a link of motives.
A cet égard, et selon un mode particulier de mise en œuvre du procédé de l'invention, on moule ensemble deux portions de chaînons accolés par l'un de leurs bords. Pour cela, il suffit de graver dans la plaque 1 deux empreintes accolées. On voit en1 figure 6 le moulage résultant, présentant deux portions de chaînons de motifs 20,21 accolées par leurs bords, dont on a arasé la base commune. Chacune des portions de chaînon de motifs forme un support de rigidification pour l'autre portion de chaînon de motifs, de sorte que ce chaînon double est bien plus rigide qu'une chaînon simple.In this respect, and according to a particular embodiment of the method of the invention, two portions of links joined together by one of their edges are molded together. For this, simply engrave in the plate 1 two adjacent prints. Resulting seen in Figure 6 one molding having two portions membered patterns 20,21 joined together at their edges, which has been leveled the common base. Each of the link portions of patterns forms a stiffening support for the other portion of the link of patterns, so that this double link is much more rigid than a single link.
En variante, il est possible de souder bord à bord deux portions de chaînons de motifs.Alternatively, it is possible to weld edge-to-edge two portions of pattern links.
Selon un autre mode particulier de mise en œuvre du procédé de l'invention illustré à la figure 7, on peut également, pour rigidifier une portion de chaînon de mo¬ tifs 30, lui accoler un support de rigidification 31.According to another particular mode of implementation of the method of the invention illustrated in FIG. 7, it is also possible, to stiffen a portion of the link of modules 30, to attach a stiffening support 31 thereto.
Selon une première variante de réalisation, on évide la plaque 1 de façon à ménager un creux qui s'étend le long de l'un des bords de la suite de motifs 2. Le creux permet de mouler le support de rigidification di¬ rectement avec le chaînon de motifs.According to a first embodiment, the plate 1 is hollowed out so as to provide a recess which extends along one of the edges of the series of patterns 2. hollow makes it possible to mold the stiffening support di¬ rectly with the link pattern.
Selon une deuxième variante de réalisation, une fois le chaînon de motifs moulé, on accole sur l'un des bords du chaînon de motifs un support de rigidification rapporté et on relie le support au chaînon par quelques points de soudure.According to a second variant embodiment, once the molded pattern linkage is attached to one of the edges of the linkage pattern a stiffening support reported and the support is connected to the link by a few soldering points.
Selon encore un autre mode particulier de mise en œuvre du procédé de l'invention illustré—à la figure 8, on forme le chaînon de motifs 40 en une spirale jointive, et on soude bord à bord les spires de la spirale ainsi formée. On distingue les points de soudure 41 (un seul est référencé) qui sont réalisés par la face arrière du chaînon, et donc invisibles de l'extérieur. On obtient ainsi une bague particulièrement esthétique.According to yet another particular embodiment of the method of the invention illustrated in FIG. 8, the pattern link 40 is formed in a contiguous spiral, and the turns of the spiral thus formed are welded edge to edge. We distinguish the weld points 41 (only one is referenced) which are made by the rear face of the link, and therefore invisible from the outside. This gives a particularly aesthetic ring.
Tous ces modes de réalisation permettent de pro¬ poser des chaînons de motifs particulièrement rigides, aptes à être utilisés pour la confection de bijoux.All these embodiments make it possible to provide links of particularly rigid patterns, suitable for use in making jewelery.
En référence à la figure 9, et selon un deuxième mode particulier de mise en œuvre, le. procédé de l'inven¬ tion comporte l'étape de creuser une empreinte 202 dans un massif, ici une plaque 201 de cire, qui possède l'avantage de pouvoir être refondue après utilisation. L'utilisation de cire pour le massif présente en outre l'avantage de permettre un usinage très rapide.With reference to FIG. 9, and according to a second particular mode of implementation, the. The method of the invention comprises the step of digging a cavity 202 in a solid mass, here a plate 201 of wax, which has the advantage of being remelted after use. The use of wax for the solid has the further advantage of allowing very fast machining.
L'empreinte 202 comporte une suite de motifs al¬ phabétiques qui sont accolés les uns aux autres de façon à se chevaucher légèrement. La suite de motifs est obte¬ nue, de la même façon que précédemment, par gravage de la plaque 201.The imprint 202 comprises a series of al¬ phabetic patterns which are contiguous to each other so as to slightly overlap. The pattern sequence is obte¬ nue, in the same way as before, by etching the plate 201.
Puis on coule dans l'empreinte 202 une résine li¬ quide 206 (par exemple une résine de polyuréthane) choi¬ sie suffisamment fluide pour qu'elle remplisse parfaite¬ ment tous les creux de l'empreinte 202. De préférence, avant le remplissage de l'empreinte 202 par la résine Ii- quide 206, on vaporise sur l'empreinte un jet de silicone en bombe favorisant le démoulage.Then a fluid resin 206 (for example a polyurethane resin) is poured into the imprint 202 which is sufficiently fluid so that it perfectly fills all the cavities of the imprint 202. Preferably, before filling of the imprint 202 by the resin II quide 206, the spray is sprayed on a spray of silicone bomb promoting demolding.
Une fois la résine 206 solidifiée, on démoule et on obtient une suite de motifs 211 telle qu'illustrée à la figure 10. Pour le démoulage, on peut déformer légère¬ ment la plaque 201, voire, si le démoulage se révèle dif¬ ficile, faire monter la plaque en température pour la di¬ later légèrement.Once the resin 206 has solidified, the mold is demolded and a series of patterns 211 as shown in FIG. 10 is obtained. For demolding, the plate 201 can be deformed slightly, even if the mold is difficult to demold. , raise the plate temperature for di¬ later slightly.
Puis, comme cela est visible à la. figure 11, la suite de motifs 211 est enroulée en spirale autour d'un gabarit 230 cylindrique de façon à présenter des bords jointifs. de préférence, la résine choisie est du type souple à l'état solide, de sorte que la suite de motifs 211 est facilement déformable. Les bords jointifs de la suite de motifs 211 sont collés, par exemple à l'aide de colle cyanolite 220. On obtient ainsi une forme mâle 210 plus particulièrement visible à la figure 12, bien plus rigide que la suite de motifs 211, et facilement manipulable. De préférence, on plonge la .forme mâle 210 dans un bain de dissolvant pour enlever la colle en excès. Il reste alors à mouler la forme mâle 210, de préférence par moulage à la cire perdue, pour obtenir directement une bague en métal faite d'un chaînon de motifs enroulé en spirale aux bords jointifs solidarisés entre eux par mou¬ lage.Then, as is visible in the. 11, the pattern suite 211 is spirally wound around a cylindrical template 230 so as to have contiguous edges. preferably, the chosen resin is of the flexible type in the solid state, so that the pattern suite 211 is easily deformable. The contiguous edges of the sequence of patterns 211 are glued, for example using cyanolite glue 220. A male shape 210 is thus more particularly visible in FIG. 12, much more rigid than the series of patterns 211, and easily manipulable. Preferably, the male form 210 is immersed in a solvent bath to remove excess glue. It then remains to mold the male form 210, preferably by lost-wax molding, to directly obtain a metal ring made of a spiral-wound pattern of links to the contiguous edges joined together by mou¬ lage.
On pourra par exemple prévoir des points d'injec¬ tion sur la face interne de la bague, qui présente une surface importante facilitant l'arrivée du métal. Une fois la bague moulée, il suffit alors d'araser les éven¬ tuelles traces d'injection, qui se situent sur la face interne de la bague et qui ne sont donc pas visibles de 1 'extérieur.For example, it will be possible to provide injection points on the inner face of the ring, which has a large surface facilitating the arrival of the metal. Once the ring is molded, it suffices then to scrape the same traces of injection, which are located on the inner face of the ring and are therefore not visible from the outside.
Le bijou obtenu est très solide et ne présente pas les faiblesses inhérentes aux soudures ou collages utilisés dans le mode de mise en œuvre précédent.The jewel obtained is very solid and does not have the inherent weaknesses of welds or collages used in the previous implementation mode.
L'invention n'est pas limitée à ce qui vient d'être décrit et englobe toute variante entrant dans le cadre défini par les revendications. Dans les deux modes de mise en oeuvre présentés, le procédé de l'invention comporte donc l'étape de réali¬ ser un intermédiaire, en l'occurrence la forme mâle, qui comporte une suite de motifs rigidifiée pour permettre sa manipulation et son moulage. La rigidifi-cation est ici obtenue par la réalisation d'une semelle, ou encore par la mise en forme de la suite de motifs en spirale et so- lidarisation des bords. L'invention n'est cependant pas limitée à ces types de rigidification, et tout autre ri- gidification pourra être envisagée, comme par exemple le collage d'une plaque de plastique au dos d'une suite de motifs obtenue par coulage de résine liquide dans l'em¬ preinte.The invention is not limited to what has just been described and encompasses any variant within the scope defined by the claims. In the two embodiments presented, the method of the invention therefore comprises the step of realizing an intermediate, in this case the male form, which comprises a series of stiffened units to allow its handling and molding . The stiffification is here obtained by the production of a sole, or by the shaping of the sequence of spiral patterns and solidification of the edges. The invention is however not limited to these types of stiffening, and any other stiffening may be envisaged, such as for example the bonding of a plastic plate on the back of a series of patterns obtained by casting liquid resin. in the imprint.
En outre, bien que pour le premier mode de mise en œuvre, l'empreinte réalisée dans la plaque en acétate n'est pas traversante, ce qui permet .d'assurer une fini¬ tion arrondie des arêtes des motifs en utilisant un outil de gravage à extrémité arrondie, on pourra bien sûr ré¬ aliser une empreinte traversante, la cire étant alors ar¬ rêtée par le fond du creux du gabarit . Bien que, dans le premier mode de mise en œuvre, l'on ait indiqué que le massif était une plaque découpée dans une feuille d'acétate, on pourra utiliser tout autre matériau comme par exemple un bloc d'aluminium. On pourra également utiliser une plaque microperforée, pour laisser l'air emprisonné par la bande de cire s'échapper lors de la pression de la bande de cire dans l'empreinte.In addition, although for the first embodiment, the impression made in the acetate plate is not through, allowing a rounded finish¬ tion of the edges of the patterns using a tool of engraving rounded end, we can of course ré¬ aliser a through impression, the wax then ar¬ rêtée by the bottom of the hollow of the jig. Although, in the first embodiment, it has been indicated that the solid is a plate cut from an acetate sheet, any other material such as an aluminum block may be used. It will also be possible to use a microperforated plate, to allow air trapped by the wax band to escape when the wax strip is pressed into the cavity.
On pourra également utiliser une plaque de cire plus dure que la cire utilisée pour former la forme mâle.It may also use a wax plate harder than the wax used to form the male form.
Bien que l'on ait indiqué que, dans le premier mode de mise en oeuvre, la base du moulage était totale- ment arasée pour obtenir un chaînon de motifs dont la ré¬ sistance structurale n'est due qu'à la liaison entre . les motifs, on pourra se contenter d'araser partiellement la base pour laisser un voile sous les motifs. On pourra en- core, bien que cela soit moins satisfaisant d'un point de vue esthétique, laisser la base.Although it has been pointed out that in the first mode of implementation the molding base was total- leveled to obtain a linkage of patterns whose structural strength is only due to the connection between. the reasons, we can be content to partially level the base to leave a veil under the grounds. It will still be possible, although less satisfactory from an aesthetic point of view, to leave the base.
Bien que l'on ait indiqué que la liaison, entre le chaînon de motifs moulé en métal et le support de ri- gidification était obtenu soit directement par moulage, soit par réalisation de points de soudure, on pourra ré¬ aliser une soudure continue le long du bord, ou encore utiliser d'autres moyens de liaison, comme un collage.Although it has been stated that the bond between the metal molded pattern link and the stiffening support is obtained either directly by molding or by means of welding points, a continuous weld can be produced. along the edge, or use other means of connection, such as a collage.
Bien que les motifs présentés sont des lettres, on pourra bien entendu reproduire d'autres motifs que des lettres, les motifs étant de préférence choisis dans une base de motifs, ce qui permet de déterminer rapidement la suite de motifs à reproduire. On pourra par exemple of¬ frir des motifs en forme de croix, de cercle, ou tout au¬ tre motif imaginable. Bien que l'on ait indiqué que l'empreinte était obtenue à l'aide d'un outil de gravage commandé par ordi¬ nateur pour, on pourra également obtenir l'empreinte par d'autres moyens, par exemple par photogravure ou encore par enfoncement dans un matériau malléable de poinçons formant chacun un motif déterminé.Although the patterns presented are letters, it will of course be possible to reproduce patterns other than letters, the patterns being preferably chosen from a pattern base, which makes it possible to rapidly determine the sequence of patterns to be reproduced. For example, we can offer motifs in the form of a cross, a circle, or any other imaginable motif. Although it has been indicated that the impression is obtained with the aid of a computer-controlled engraving tool, the impression can also be obtained by other means, for example by photoengraving or else by embedding in a malleable material punches each forming a specific pattern.
Bien que, pour réaliser la suite de motifs de la forme mâle, on utilise un matériau de prise d'empreinte tel que de la cire en bande ou encore de la résine li¬ quide, tout autre matériau apte à remplir l'empreinte du massif pourra être utilisé, comme du mastic durcissable. Although, to achieve the sequence of patterns of the male form, using an impression material such as strip wax or the li¬ quide resin, any other material capable of filling the footprint of the massif may be used, such as curable sealant.
