Description

DESCRIZIONE DEL TROVATO DESCRIPTION OF THE FOUND

Dell’invenzione industriale dal titolo: Of the industrial invention entitled:

Separatore per matrici in gomma o silicone per orafi e odontotecnici. Separator for rubber or silicone matrices for goldsmiths and dental technicians.

Le matrici in gomma o silicone per uso orafo ed odontotecnico vengono solidificate se effettuate “a freddo†e vulcanizzate se eseguite a cottura, all'interno di specifici stampi chiamati staffe che ne determinano la forma. Si producono per duplicare oggetti attraverso il complesso procedimento della cera persa. The rubber or silicone matrices for goldsmith and dental technician use are solidified if made â € œcoldâ € and vulcanized when fired, inside specific molds called brackets that determine their shape. They are produced to duplicate objects through the complex process of lost wax.

Dopo la cottura, la matrice si presenta come un blocco unico difficile da dividere (fig.1 tav.4). Il separatore eseguito in lamiera sottile cinque decimi di millimetro in acciaio inox e ripiegata per definire svariati triangoli (fig.5 tav.1), viene inserito fra le due metà della matrice prima della cottura garantendone facile apertura e ricongiunzione (fig. 2 tav. 2 e fig. 3 tav. 3). After firing, the matrix appears as a single block that is difficult to divide (fig. 1 table 4). The separator made of thin sheet metal five tenths of a millimeter in stainless steel and folded to define various triangles (fig. 5 table 1), is inserted between the two halves of the matrix before firing, guaranteeing easy opening and rejoining (fig. 2 tab. 2 and fig. 3 table 3).

Il trovato potrà presentare un numero variabile di denti e forme differenti adattabili ad esigenze pratiche ed estetiche. The invention may have a variable number of teeth and different shapes adaptable to practical and aesthetic requirements.

RIVENDICAZIONI 1. Matrice di gomma o silicone per un uso per la duplicazione di oggetti in campo orafo e odontotecnico mediante la tecnica della “cera persa†, in cui detta matrice à ̈ fabbricata inserendo fra due metà della massa della matrice, prima della sua cottura e conseguente vulcanizzazione, un elemento separatore costituito da un anello di lamiera sottile di acciaio inox di circa cinque decimi di millimetro di spessore e ripiegato in modo da definire lungo il suo sviluppo anulare una pluralità di porzioni in rilievo di forma triangolare, per cui, dopo la vulcanizzazione della matrice, detto elemento separatore garantisce una facile apertura e perfetta ricongiunzione con incastro a triangolo fra le due metà della matrice, nonché una facile estrazione dell'oggetto da duplicare senza l’uso di bisturi. CLAIMS 1. Matrix of rubber or silicone for use for the duplication of objects in the goldsmith and dental technician field by means of the `` lost wax '' technique, in which said matrix is manufactured by inserting between two halves of the mass of the matrix, before its firing and consequent vulcanization, a separator element consisting of a ring of thin stainless steel sheet about five tenths of a millimeter thick and folded in such a way as to define along its annular development a plurality of triangular-shaped portions in relief, therefore, after the vulcanization of the matrix, said separator element guarantees an easy opening and perfect rejoining with a triangular joint between the two halves of the matrix, as well as an easy extraction of the object to be duplicated without the use of a scalpel. 2. Metodo per la fabbricazione di una matrice di gomma o silicone per la riproduzione di oggetti tramite la tecnica della "cera persa" in campo orafo e odontotecnico, comprendente le seguenti fasi: provvedere un elemento separatore costituito da un anello di lamiera sottile di acciaio inox di circa cinque decimi di millimetro di spessore e ripiegato in modo da definire lungo il suo sviluppo anulare una pluralità di porzioni in rilievo di forma triangolare; inserire detto elemento separatore fra due metà della massa della matrice, prima della sua vulcanizzazione; per cui, dopo la vulcanizzazione della matrice, detto elemento separatore garantisce una facile apertura e perfetta ricongiunzione con incastro a triangolo fra le due metà della matrice, nonché una facile estrazione dell'oggetto da duplicare senza l'uso di bisturi.2. Method for the manufacture of a rubber or silicone matrix for the reproduction of objects using the "lost wax" technique in the goldsmith and dental technician field, comprising the following steps: providing a separator element consisting of a ring of thin stainless steel sheet about five tenths of a millimeter thick and folded so as to define along its annular development a plurality of triangular shaped portions in relief; inserting said separator element between two halves of the mass of the matrix, before its vulcanization; therefore, after the vulcanization of the matrix, said separator element guarantees an easy opening and perfect rejoining with a triangular joint between the two halves of the matrix, as well as an easy extraction of the object to be duplicated without the use of a scalpel.
