Description
<B>Procédé de</B> fabrication <B>d'un</B> cadran pour montre La présente invention a pour objet un pro cédé de fabrication d'un cadran pour montre. Ce procédé est caractérisé par le fait que, par tant d'une ébauche en métal, en forme de pla que, on frappe sur cette dernière des signes horaires apparaissant en relief sur sa face an térieure, puis, également par frappe, découpe la matière située entre ces signes de façon à former un tour d'heures ajouré.
Le dessin annexé représente, à titre d'exemple, une montre munie d'un cadran ob tenu par mise en oeuvre du procédé suivant la présente invention.
La fig. 1 est une vue en plan de cette montre ; et la fig. 2 en est une coupe, à échelle agran die, suivant la ligne II-II de la fig. 1.
La montre représentée est une montre- squelette dont le mouvement 1 est maintenu suspendu par le cadran 2, fixé par sa périphé rie dans la boîte 3. Le cadran présente un tour d'heures ajouré 2a situé au-dessus d'une zone annulaire libre se trouvant entre le mouvement 1 et la boîte 3.
Le cadran est obtenu de la manière sui- vante : partant d'une ébauche circulaire plane, les signes 2a sont tout d'abord frappés de ma nière à apparaître en relief sur la face anté rieure du cadran ; puis, par frappe également, la matière située entre les signes 2a est décou pée, produisant ainsi le tour d'heures ajouré. Le cadran est ensuite bombé par frappe.
Bien entendu, l'invention n'est pas limitée au cadran représenté, mais pourrait s'appli quer à des cadrans dont les tours d'heures pourraient avoir des formes très différentes. -
<B> Method of </B> manufacturing <B> a </B> dial for a watch The present invention relates to a process for manufacturing a dial for a watch. This process is characterized by the fact that, by so much of a metal blank, in the form of a plate, hour signs appearing in relief on its anterior face are stamped on the latter, then, also by stamping, the material is cut. located between these signs so as to form an openwork hour circle.
The appended drawing represents, by way of example, a watch provided with a dial obtained by implementing the method according to the present invention.
Fig. 1 is a plan view of this watch; and fig. 2 is a section, on an enlarged scale, along the line II-II of FIG. 1.
The watch shown is a skeleton watch, the movement 1 of which is kept suspended by the dial 2, fixed by its periphery in the case 3. The dial has a perforated hour circle 2a located above a free annular zone. located between movement 1 and box 3.
The dial is obtained as follows: starting from a planar circular blank, the signs 2a are first of all stamped so as to appear in relief on the front face of the dial; then, also by striking, the material located between the signs 2a is cut off, thus producing the openwork hour circle. The dial is then domed by striking.
Of course, the invention is not limited to the dial shown, but could be applied to dials the hour turns of which could have very different shapes. -
