Description

Verfahren zur Herstellung von Massewiderständen mit gerader oder gekrümmter Leiterbahn Im Patent 732 464, ist ein Verfahren zur Herstellung von Mass ewidbrständien mit Zonen verschiedr spezifischeir Leitfähigkeit beschrieben, bei welchem die Massen rnit verschiedenen spezifischen Wnderstämden in sich durchdringenden parallelen, Streifen auf ein stanzfähiges Trägermaterfal aufgetragen und aus diesem über sämtliche Streifen sich. erstreckende ringförmige oder gerade Stücke ausgestanzt werden. Es gibt nun eine Reihe von sonst ausgezencnhetenWiderstandsmassen, welche nach der Trocknung zwar auf der Unterlage genügend festhaften, jedoch so spröde sind, daß sie beim Stanzen, splittern und dadurch, dien Massewiderstand =brauch, bar machen. Die: Erfindung bietet nun einen Weg, um auch. derartige Widerstandsmassen für das Verfahren gemäß dem Hauptpatent anwendbar zu machen. Erfirndungtsgemäß werden die geraden; oder gekrümmten Widerstandsträger zunachs.t ausgestanzt, dann auf einem Halter vorzugsweise reihenförmig, insbesondere parallel; zueinander angeordnet und die Reihe samt Halter mit den Zonen aus Wid,jrstan.d,smass" bedeckt. Vorteilhaft verwendet man als Halter für die Staimstücke eine Schablone. Man erreichst so eine hinreichende Genauigkeit und Reproduzierbarkeit, um praktisch eine große Zahl von Widerständ; ir ohne Ausschur herstellen zu können. Gemäß seinem weiteren Erfindun gs.merkina 1 werden als Halter für die Stanzstücke d,i durch,stanzten Trägerstreifen selbst bmutzt. Dies ist von: technischer und auch wirtschaftl.icher Bedeutung, insofern diese Stanzs:treiieii ein genau: s Fiiipassen der Stanzstücke gewährleisten. Da sich ferner jede Schablone beim Aufspritzen der hasse allmählich zusetzt, müßte sie bei wiederholter Benutzung jedesmal vorher gereinigt werden. Dieser achte:il entfällt bei Verwendung der beim Stanzen zwangsläufig anfallenden und an sich wertlosen durchstanzten Trägerstreifen als Schablone.Process for the production of ground resistors with straight or curved conductor tracks In the patent 732 464, a process for the production of ground resistors with zones of different specific conductivity is described, in which the masses with different specific resistance strains are applied in parallel, interpenetrating strips on a punchable carrier material and from this over all stripes. extending annular or straight pieces are punched out. There are now a number of otherwise unusual resistance masses which, after drying, adhere sufficiently firmly to the surface, but are so brittle that they splinter when punching and thereby render the mass resistance usable. The: invention now offers a way to too. to make such resistance masses applicable to the method according to the main patent. According to the invention, the straight; or curved resistor carrier first punched out, then on a holder, preferably in a row, in particular in parallel; arranged to each other and the row including the holder covered with the zones from Wid, jrstan.d, smass ". It is advantageous to use a template as a holder for the stem pieces. In this way, sufficient accuracy and reproducibility are achieved in order to practically deal with a large number of resistances; ir According to his further invention gs.merkina 1, punched carrier strips themselves are used as holders for the punched pieces d, i. This is of: technical and also economic importance, insofar as these punchings: treiieii exactly: Since every stencil gradually clogs up when the hasse is sprayed on, it would have to be cleaned beforehand each time it is used again.

Das Verfahren gemäß der Erfindung soll an Hand der Zeichnung in einem Ausführungsbeispel näher ,erläutert werden.The method according to the invention is based on the drawing in one Exemplary embodiments are explained in more detail.

Gemäß Fig. i verdien die herzustellenden Widerstandsbabnen b aus einem Streifen, a, mittels elirne:s homp.lettschniittes ausgestanzt, hierauf werden die Widerstandsbahnen b wieder in den Streifen a hineingelegt und mittels einer geeigneten Vorrichtung mit ZV iderstandsinasse in verschiedenen Längszo,nen bedeckt.According to FIG. 1, the resistance strips b to be produced are punched out of a strip, a, by means of elirne: s homp.lettschniittes, then the resistance strips b are placed back into the strip a and covered in different longitudinal zones by means of a suitable device with ZV resistance elements.

Gemäß Fig. 2 dient zur Halterung der ausgestanzten Widerstandsbahnen, b diel feste Schablone c, die mit krerisrunden Auflagen in Abetänden besetzt ist, welche von den eben.- falls kreisfärmI.gen Ininenkaniten der Wider- standsbahnen umfa.ßt werden. An Stelle der in der Zeichnung dargestellten Widerstände mit gekrümmter Leiterbahn köntrai naturgemäß auch solche finit gerader I::-iterhalin hergeLtellt verdien. According to Fig. 2 is used to hold the punched resistance tracks, b the fixed template c, which is occupied with krerisrunden pads in AbetÄNDEN, which of the just.- if circular internal canals of the resistance standing tracks are included. Instead of the one shown in the drawing Resistors with a curved conductor track Naturally, such finitely straighter can also be used I :: - iterhalin produced deserve.
