Description

  

  Verfahren zur Herstellung von     Ziüerndruckacheiben    für Büromaschinen  und Registrierkassen.    Bis jetzt wurden solche Ziffernscheiben,  bei denen die Ziffern wie bei     Sehreibmaschi-          nenty        pen    erhaben sein mussten, für kleinere       Serien        graviert    oder, wenn sich die Herstel  lung einer     Gussform    lohnte, in     Spritzguss    her  gestellt oder, wenn die Rollen von Stahl sein       mussten,    im     Gesenk        gepresst.    Das erste Ver  fahren ist nicht rationell,

   während die an  dern mit erheblichen Werkzeugkosten ver  bunden sind.  



  Die vorliegende Erfindung betrifft ein  Verfahren zur     Herstellung    solcher Ziffern  scheiben     mittels    Walzen, das eine rationelle  Arbeitsweise ermöglicht.  



  In der Zeichnung     ist    die Wirkungsweise       beispielsweise    dargestellt.     Fig.    1 ist ein sche  matischer Grundruss,     Fig.    2 eine Seiten  ansicht der bei der Herstellung     verwendeten     Scheiben. Die zu prägende Scheibe 1 ist     zwi-          ehen    zwei     Stahlscheiben    2 durch .Schrauben  auf einem Zahnrad 3     festgepresst.    In einer  Stahlscheibe 4, welche auf dem     zweiten    Zahn  rad 5 festsitzt, sind die zu prägenden Zei  chen 7 negativ eingraviert.

   Durch ein Zahn  rad 9 kann das eine Zahnrad 5 in Drehung  versetzt werden, wodurch sich die beiden  Scheiben 1 und 4 aufeinander abwälzen. Mit-         tels    der exzentrisch     gelagerten    Welle ö kann  die     Mutterscheibe    4 durch Drehen des Hebels  8 unter allmählichem     Kleinerwerden    des       Achsabstandes    der sich abwälzenden Schei  ben gegen     die    zu prägende Scheibe 1 gepresst  werden. Das: Material, welches dadurch auf  der Scheibe 1 verdrängt wird, füllt die in der  härteren     Mutterscheibe    4 vertieft eingravier  ten Zeichen aus, wodurch dieselben auf der  zu prägenden Scheibe 1 in positiver Form       entstehen.  



  Process for the production of Ziüerndruckacheiben for office machines and cash registers. Up until now, such dials, where the digits had to be raised like typewriters, were engraved for smaller series or, if the production of a mold was worthwhile, made by injection molding or, if the rollers had to be made of steel, in Die-pressed. The first procedure is not rational

   while others are associated with considerable tool costs.



  The present invention relates to a method for the production of such numeric disks by means of rollers, which enables efficient operation.



  In the drawing, the mode of operation is shown for example. Fig. 1 is a schematic plan view, Fig. 2 is a side view of the discs used in the manufacture. The disc 1 to be embossed is pressed firmly between two steel discs 2 by means of screws on a gear 3. In a steel disk 4, which is stuck on the second gear wheel 5, the characters to be embossed 7 are negatively engraved.

   A gear wheel 9 can set a gear 5 in rotation, whereby the two disks 1 and 4 roll on each other. By means of the eccentrically mounted shaft 6, the nut disk 4 can be pressed against the disk 1 to be embossed by turning the lever 8 while the axial distance between the rolling disks gradually decreases. The: Material, which is thereby displaced on the disk 1, fills the indented characters in the harder mother disk 4, whereby the same arise on the disk 1 to be embossed in positive form.
