Zime ä polir et procede pour sa fabrication. Les limes, ä polir aotuellement utilisees sont faites exelusivement en metal. La pre- sente invention comprend une lime ä polir qui est caracterisee en ce qu'au moins la partie de son epaisseur, dans laquelle sont taillees ses dents, est en matiere vitreuse, par egem- ple en verre, cristal, rubis synthetique, ma- tiere vitrifiee (teile que de 1'email). Zime to polish and process for its manufacture. The polishing files currently used are made exclusively of metal. The present invention comprises a polishing file which is characterized in that at least the part of its thickness, in which its teeth are cut, is made of vitreous material, for example glass, crystal, synthetic ruby, masonry. - vitrified tiere (same as enamel).
L'invention camprend egalement un pro- c6de de fabrication dune teile lime ä polir, qui est caracterise en ce qu'on taille les dents dann la matiere vitreuse susdite ä 1'etat de durete definitive. The invention also includes a process for manufacturing such a polishing file, which is characterized in that the teeth are cut in the above-mentioned vitreous material in the state of definitive hardness.
Voici, ä titre d'exemples, la description de quelques formes d'executian de 1a lime ä polir que comprend Pinvention, ainsi que la description, egalement ä titre d'exemples, de quelques mises en aeuvre du procede de fabricatiön Pour la reulisation dune premiere forme d'egecution de 1a Time, an peut prendre une laure de verre transparent ou opaque, par exemple, dans laquelle an taille ä la meule une serie de dents paralleles, continues sur toute leur longueur et s'etendant d'un Bord ä 1'autre @de cette laure. Here, by way of examples, is the description of some forms of execution of the polishing file that the invention comprises, as well as the description, also by way of examples, of some implementations of the manufacturing process for the use of a first form of execution of 1a Time, an can take a laure of transparent or opaque glass, for example, in which an grinds a series of parallel teeth, continuous over their entire length and extending from edge to edge. the other @of this Laura.
Dorns -une autre forme d'execution, an peut prendre un support en mUal, par exem- ple de la forme dune laure, que Fon revet sur 1'uue au,moins de ses grandes faces, dune couche de matiere vitrifiee teile que de 1'6mail, ayant une epaisseur au moins ggale ä 1a hauteur des dents que 1'on.desire obtenir. Une fois kette couche de mauere vitrifiee obtenue au degre,de durete definitive desire, an taille en eile les dents de la lime, par exemple comme an vieret de 1'indiquer poux la premiere forme d'egecution. Biere entendu, 1e support peut eire completement enrobe dans la matiere vitrifiee et Fon. peut prevoir une denture sur chacune de ses grandes faces. In another form of execution, an metal support can be taken, for example in the shape of a lavra, which is coated on the window, at least on its large faces, with a layer of vitrified material such as 1'6mail, having a thickness at least equal to 1a height of the teeth that 1'on.desire to obtain. Once this layer of vitrified stone has been obtained to the degree of definitive hardness desired, the teeth of the file are sharpened, for example, as if to indicate it for the first form of execution. Beer understood, the support can be completely coated in the vitrified material and Fon. can provide a toothing on each of its large faces.
Les limes ä polir obtenues de la maniere decrite presentent des dents dort la tranche est parfaitement lisse sur toute sa longueur, par 1e fait que la taille a lieu lomque la ma- tiAre dans laquelle ms dents sont taillees se trouve ä 1'etat de durete definitive et que, The polishing files obtained in the manner described have teeth whose edge is perfectly smooth over its entire length, by the fact that the size takes place when the material in which my teeth are cut is in the state of hardness. definitive and that,
par consequent., aucun traitement thermique consecutif ä la taille West necessaire. Les limes decrites ont leur application, par exemple comme limes ir polir les ongles.
therefore, no post-cut heat treatment is necessary. The files described have their application, for example as nail polishing files.
