Description

  

   <Desc/Clms Page number 1> 
 Procédé de fabrication d'un cadran et cadran obtenu par ce procédé La présente invention a pour objet un procédé de fabrication d'un cadran, notamment d'un cadran de montre, caractérisé par le fait qu'on injecte, sur une plaquette en matière plastique synthétique, une matière plastique synthétique d'une couleur différente de celle de ladite plaquette, de façon à constituer des signes sur celle-ci. 



  Cette invention a également pour objet un cadran obtenu par le procédé ci-dessus et caractérisé par le fait qu'il présente des signes sur au moins une de ses faces. 



  Selon une mise en    aeuvre   du procédé ci-dessus, on peut fabriquer un cadran de montre en injectant sur une des faces d'une plaquette en matière plastique synthétique, par exemple en    polystirène,   une matière plastique synthétique d'une couleur    diffé-      rente   de celle constituant ladite plaquette de façon à constituer des chiffres sur celle-ci ; à cet effet, on place sur une des faces de ladite plaquette un moule ou un masque présentant des orifices correspondants auxdits chiffres, puis la plaquette pourvue de son masque est disposée en regard de l'orifice d'extrusion d'une machine à injecter la matière plastique, du    polystirène   par exemple, constituant les chiffres du cadran. 



  La plaquette peut être moulée en une matière plastique synthétique phosphorescente, du    polystirène   par exemple, contenant des particules d'une matière phosphorescente, les chiffres étant alors constitués en une matière plastique non phosphorescente. 



  La plaquette peut aussi être en une matière plastique non phosphorescente, les    chiffres   étant alors en une matière plastique phosphorescente. 



  La plaquette portant les    chiffres   peut être convexe ou concave et présenter une forme ronde ou polygonale, vue en plan. Des cadrans d'appareils de mesure, notamment des compteurs de vitesse, peuvent aussi être    réalisés   par le procédé indiqué ci-dessus. 



  ta plaquette en matière plastique peut aussi être métallisée sur au moins une de ses faces, c'est-à-dire recouverte de fines particules métalliques, d'argent par exemple, cette opération    s'effectuant   dans le vide d'une manière connue.

 Method of manufacturing a dial and dial obtained by this method The present invention relates to a method of manufacturing a dial, in particular a watch dial, characterized by the fact that one injects, on a wafer of material synthetic plastic, a synthetic plastic material of a color different from that of said plate, so as to constitute signs on the latter.



  Another subject of the invention is a dial obtained by the above method and characterized in that it has signs on at least one of its faces.



  According to an implementation of the above process, it is possible to manufacture a watch dial by injecting on one side of a plate made of synthetic plastic material, for example polystyrene, a synthetic plastic material of a different color from that constituting said plate so as to constitute figures thereon; for this purpose, a mold or a mask having orifices corresponding to said numbers is placed on one of the faces of said wafer, then the wafer provided with its mask is placed opposite the extrusion orifice of an injection machine. plastic material, polystyrene for example, constituting the numbers of the dial.



  The plate may be molded from a phosphorescent synthetic plastic material, for example polystyrene, containing particles of a phosphorescent material, the digits then being made of a non-phosphorescent plastic.



  The plate can also be of a non-phosphorescent plastic material, the digits then being in a phosphorescent plastic.



  The plate bearing the numbers may be convex or concave and have a round or polygonal shape, viewed in plan. Dials of measuring devices, in particular speedometers, can also be produced by the method indicated above.



  your plastic plate can also be metallized on at least one of its faces, that is to say covered with fine metallic particles, silver for example, this operation being carried out in a vacuum in a known manner.
