EMI1.2
Den Gegenstand der Erfindung bildet nun ein Stromdurchführungsdraht. bei dem die beim Ziehen der Drähte sonst häufig auftretenden Längsrillen beseitigt und eventuell durch quer oder spiralfornug verlaufende Rillen ersetzt sind. Derartige Drähte werden in einfacher Weise beispielsweise hergestellt. indem man entweder den gezogenen Draht abschleift oder quer oder spiralförmig verlaufende Rillen. z. B. durch Ziehen mittels eines rotierenden Ziehsteines oder auch auf beliebige andele Weise erzeugt.
Durch die Rotation des Ziehsteines wird bewirkt. dass die Ziehrillen spiralförmig längs des Drahtes ver- laufen. Wird ein mit solchen Spiralrillen versehener Draht aus reinem Kupfer an einer Stelle flachgedrückt. so verschwinden die Rillen an der flachen Seite. während sich an den Kanten Einkerbungen bilden, welche

EMI1.1
EMI1.2
The subject of the invention now forms a power feedthrough wire. in which the longitudinal grooves that otherwise often occur when the wires are pulled are eliminated and possibly replaced by transverse or spiral grooves. Such wires are produced in a simple manner, for example. by either grinding off the drawn wire or grooves running transversely or in a spiral shape. z. B. generated by pulling by means of a rotating die or in any other way.
It is caused by the rotation of the drawing die. that the drawing grooves run spirally along the wire. If a wire made of pure copper with such spiral grooves is flattened at one point. so the grooves on the flat side disappear. while notches are formed on the edges, which

Since when the lamp base is squeezed, the glass is mechanically pressed into the grooves in places, namely on the front and back of the base, creating continuous channels. along which air could penetrate. prevent.
PATENT CLAIMS:
1. Feedthrough wire for electric light bulbs, characterized by transverse or spiral grooves shown on the wire. for the purpose. those when pulling as a result of use
