Description
Description Domaine technique [0001] La présente invention concerne un procédé de fabrication de composants horlogers comprenant un revêtement décoratif en aventurine, en particulier un procédé de fabrication de cadrans de montre formés partiellement d’aventurine.Description Technical Field [0001] The present invention relates to a method for manufacturing watch components comprising a decorative coating in aventurine, in particular a method for manufacturing watch dials partially formed from aventurine.
Arrière-plan technologique [0002] Il est connu depuis longtemps de réaliser des montres incorporant pour leur décoration des parties réalisées en pierre précieuse ou semi-précieuse. En particulier, il est connu de réaliser des cadrans en pierre précieuse, par exemple en lapis-lazuli, qui donnent aux montres un caractère de joaillerie.Technological background It has long been known to make watches incorporating for their decoration parts made of precious or semi-precious stone. In particular, it is known to produce dials in precious stone, for example in lapis lazuli, which give the watches a character of jewelry.
[0003] Pour réaliser des cadrans en pierre précieuse ou semi-précieuse, on part de pierres que l’on découpe en fines tranches, lesquelles sont ensuite polies et découpées. Grâce aux techniques de découpage actuel, il est possible de découper divers profils et de réaliser des ouvertures dans les fines plaquettes obtenues. On notera que pour rendre le cadran en pierre moins cassant et assurer son positionnement dans la montre, la personne du métier colle généralement les fines plaquettes de pierre sur des supports métalliques, de préférence en métal noble.To make precious or semi-precious stone dials, we start with stones that we cut into thin slices, which are then polished and cut. Thanks to current cutting techniques, it is possible to cut various profiles and make openings in the thin wafers obtained. Note that to make the stone dial less brittle and ensure its positioning in the watch, the person skilled in the art generally glues the fine stone slabs on metal supports, preferably of noble metal.
[0004] Les techniques classiques de fabrication de cadrans en pierre précieuse ou semi-précieuse ont également été utilisées pour fabriquer des cadrans en aventurine. On notera que le terme ’aventurine’ a été initialement utilisé pour décrire des verres colorés particuliers qui ont été fabriqués par le passé dans des verreries à Murano en Italie. Ces verres colorés présentent un scintillement caractéristique dû à la présence de petits cristaux de cuivre qui se forment lors de la fusion du verre dans un four à haute température et qui grossissent lors d’un lent refroidissement du verre obtenu. Ensuite, le terme ’aventurine’ a été utilisé pour nommer des pierres naturelles, en particulier des pierres en quartz coloré présentant un tel scintillement.Conventional techniques for manufacturing dials of precious or semi-precious stone have also been used to manufacture dials in aventurine. Note that the term "aventurine" was originally used to describe particular colored glasses that have been made in the past in glassworks in Murano, Italy. These colored glasses exhibit a characteristic flicker due to the presence of small copper crystals which are formed when the glass is melted in an oven at high temperature and which enlarge during the slow cooling of the glass obtained. Then, the term avent aventurine ’was used to name natural stones, especially colored quartz stones with such a sparkle.
[0005] On trouve des verres d’aventurine de diverses couleurs, notamment de couleur rouge, de couleur bleue et de couleur verte. Les morceaux de verre d’aventurine ont un aspect de pierre semi-précieuse, de sorte que l’homme du métier les considère comme des pierres semi-précieuses artificielles qu’il nomme généralement ’aventurine’. Ces verres d’aventurine donnent à si méprendre, après découpe de morceaux à disposition et polissage de plaquettes ou autres formes, un aspect de pierre naturelle aux cadrans ou autres composants horlogers réalisés à partir de ces morceaux d’aventurine. Il existe des morceaux d’aventurine de couleur bleu profond, dû à une présence de Cobalt dans leur composition, qui sont particulièrement appréciés pour les applications horlogères, car les cadrans obtenus à partir de ces morceaux d’aventurine présentent un aspect de ciel étoile de toute beauté grâce au scintillement des petits cristaux de cuivre.There are aventurine glasses of various colors, including red, blue and green. The pieces of aventurine glass have a semiprecious stone appearance, so that those skilled in the art regard them as artificial semiprecious stones which he generally calls "aventurine". These aventurine glasses give, if misunderstanding, after cutting out pieces at disposal and polishing of wafers or other shapes, a natural stone appearance to the dials or other horological components made from these pieces of aventurine. There are pieces of aventurine in deep blue color, due to the presence of Cobalt in their composition, which are particularly appreciated for watchmaking applications, because the dials obtained from these pieces of aventurine have an aspect of star sky of beautiful thanks to the sparkle of small copper crystals.
[0006] Pour réaliser avec de l’aventurine des cadrans et disques / anneaux d’affichage pour pièces d’horlogerie, la personne du métier travaille cette matière comme on travaille une pierre semi-précieuse ou un cristal de quartz, en découpant des morceaux d’aventurine en fines plaquettes qui sont ensuite collées sur des supports métalliques. De tels cadrans et disques / anneaux d’affichage habillent des montres de plusieurs marques horlogères, entre autres des montres OMEGA, Jaquet Droz et Bulgari™.[0006] To make dials and discs / display rings for timepieces with aventurine, the skilled person works this material as one works a semi-precious stone or a quartz crystal, by cutting pieces. aventurine in thin strips which are then glued to metal supports. Such dials and display discs / rings adorn watches of several watch brands, including OMEGA, Jaquet Droz and Bulgari ™ watches.
[0007] La fabrication de cadrans en aventurine telle que décrite ci-avant présente divers inconvénients. En effet, ces cadrans en aventurine se révèlent difficiles à préparer et à assembler. La découpe de morceaux d’aventurine en fines tranches et le découpage de profils désirés dans ces tranches génèrent passablement de déchets. Ensuite, l’aventurine présente assez souvent de petites bulles d’air qui apparaissent après polissage et qui rendent inutilisables les fines plaquettes obtenues. De plus, ces fines plaquettes sont fragiles et donc cassantes. Leur manipulation est périlleuse et l’assemblage de ces fines plaquettes avec leurs supports respectifs pour réaliser les cadrans est une opération délicate.The manufacture of aventurine dials as described above has various drawbacks. Indeed, these aventurine dials prove difficult to prepare and assemble. Cutting pieces of aventurine into thin slices and cutting desired profiles into these slices generate a lot of waste. Then, aventurine quite often presents small air bubbles which appear after polishing and which render the thin platelets obtained unusable. In addition, these fine platelets are fragile and therefore brittle. Their handling is perilous and the assembly of these fine plates with their respective supports to make the dials is a delicate operation.
[0008] On notera encore que le décalquage de motifs et/ou index sur des plaquettes d’aventurine présente déjà un risque de les fissurer. Si on souhaite avoir des motifs et/ou index en relief sur un cadran, on peut notamment les réaliser en métal par électroformage sur une plaquette d’aventurine; mais un tel procédé est généralement réalisé sur la plaquette d’aventurine avant le collage à son support. Ce procédé nécessite diverses manipulations de sorte que le risque de casser la plaquette est important. On peut aussi obtenir des motifs et/ou index en métal, notamment en métal noble, en structurant le support métallique du cadran de sorte que ces motifs et/ou index soient en relief relativement à la surface destinée à recevoir par collage la plaquette d’aventurine. Dans ce dernier cas, il faut découper dans la plaquette d’aventurine de nombreuses petites ouvertures correspondant à ces motifs et/ou index. Cependant, l’assemblage d’une fine plaquette d’aventurine ainsi ajourée avec son support présente un risque important de la casser. En effet, la moindre contrainte mécanique exercée sur une telle plaquette peut la casser, par exemple une légère pression exercée sur cette plaquette alors que le bord d’une de ses ouvertures est partiellement en butée sur un relief correspondant ou simplement par friction entre la plaquette et un motif ou index lors de la mise en place de la plaquette. On comprend donc qu’il faut prévoir des tolérances de fabrication de sorte que de petites fentes entre les motifs et/ou index en relief et la plaquette d’aventurine ajourée apparaissent, ce qui nuit à l’esthétique du cadran et donc à sa qualité.It will also be noted that the pattern transfer and / or index on aventurine wafers already presents a risk of cracking them. If one wishes to have patterns and / or indexes in relief on a dial, one can in particular make them out of metal by electroforming on an aventurine plate; but such a process is generally carried out on the aventurine plate before bonding to its support. This process requires various manipulations so that the risk of breaking the wafer is significant. It is also possible to obtain patterns and / or indexes of metal, in particular of noble metal, by structuring the metallic support of the dial so that these patterns and / or indexes are in relief relative to the surface intended to receive by gluing the wafer. aventurine. In the latter case, it is necessary to cut out in the aventurine plate many small openings corresponding to these patterns and / or indexes. However, the assembly of a thin aventurine plate thus perforated with its support presents a significant risk of breaking it. Indeed, the slightest mechanical stress exerted on such a plate can break it, for example a slight pressure exerted on this plate while the edge of one of its openings is partially in abutment on a corresponding relief or simply by friction between the plate and a pattern or index when the insert is put in place. It is therefore understood that it is necessary to provide manufacturing tolerances so that small slits between the patterns and / or index in relief and the perforated aventurine plate appear, which affects the aesthetics of the dial and therefore its quality. .
[0009] Ensuite, on a remarqué que même une fois collées sur leurs supports respectifs, ces fines plaquettes d’aventurine restent fragiles et peuvent se fissurer ou casser lors de chocs auxquels les montres doivent généralement résister. Lors de tels chocs, on a aussi observé que de petits fragments d’aventurine se détachent parfois de la surface de cadrans revêtusThen, we noticed that even once glued on their respective supports, these thin aventurine plates remain fragile and can crack or break during shocks which watches must generally resist. During such shocks, it has also been observed that small fragments of aventurine sometimes detach from the surface of coated dials
CH 714 962 A2 de plaquettes d’aventurine. Ceci engendre de petites crevasses visibles à l’œil, ce qui dégrade donc l’aspect esthétique de ces cadrans. De plus, ces petits fragments peuvent aisément s’introduire dans les mouvements horlogers de montres équipées de cadrans en aventurine ainsi détériorés par des chocs et nuire à leur bon fonctionnement, voir les bloquer.CH 714 962 A2 from aventurine platelets. This creates small crevices visible to the eye, which therefore degrades the aesthetic appearance of these dials. In addition, these small fragments can easily get into watch movements of watches fitted with aventurine dials thus damaged by shocks and impair their proper functioning, or even block them.
[0010] Finalement, un autre inconvénient provient du fait que les réalisations possibles sont limitées par le fait que l’on part généralement de plaquettes d’aventurine planes pour réaliser des cadrans, de sorte qu’il s’agit de cadrans plats. On peut certes usiner des morceaux d’aventurine de manière à réaliser des verres d’aventurine bombés au moins supérieurement, mais le coût de fabrication sera très élevé.Finally, another drawback stems from the fact that the possible embodiments are limited by the fact that one generally starts from flat aventurine wafers to make dials, so that these are flat dials. It is certainly possible to machine pieces of aventurine so as to produce curved aventurine glasses at least above, but the manufacturing cost will be very high.
[0011] Les inconvénients susmentionnés, et éventuellement d’autres encore, interviennent pour la décoration d’autres parties d’habillage d’une montre, par exemple de lunettes, ou de parties de mouvements horlogers, par exemple de ponts ou de masses oscillantes, avec de l’aventurine par des techniques similaires à celle décrite précédemment pour la fabrication de cadrans et disques / anneaux d’affichage, à savoir en découpant des portions dans un morceau d’aventurine pour obtenir des pièces d’aventurine massives qui sont ensuite polies et collées sur des supports configurés pour recevoir ces pièces d’aventurine massives.The aforementioned drawbacks, and possibly still others, occur for the decoration of other parts of the covering of a watch, for example glasses, or parts of watch movements, for example of bridges or oscillating masses , with aventurine by techniques similar to that described above for the manufacture of dials and discs / display rings, namely by cutting portions from a piece of aventurine to obtain massive pieces of aventurine which are then polished and glued on supports configured to receive these massive pieces of aventurine.
