Abstract (en)

[origin: DE19951775C1] Prior to fitting to opening roller, the card wire is wound on edge into a coil corresponding to the roller diameter within \!5%. It is placed on a carrier and the usual cleaning, electrochemical de-burring and nickel- diamond coating processes are carried out in this configuration. To provide mechanical assistance to de-burring in the confined space, solid particles of 1 - 1000 mu m are added to the de-burring liquid at a concentration of 0.2 - 20 g/l.. The particles are made of material with density of 1.2 - 4.5 g/cm<3>, which is not attacked by the liquid.

Abstract (de)

Die Erfindung betrifft ein verfahren zur Herstellung eines Garniturdrahts (2) der zum Aufbringen auf einen Auflösewalzengrundkörper (1) geeignet ist, dadurch gekennzeichnet, daß ein zur Herstellung von Garniturdraht üblicher Rohdraht hochkant zu einer Drahtrolle verarbeitet wird, bei der die Zähne des Drahtes senkrecht zur Rollenachse stehen und die einen Durchmesser hat, der dem Durchmesser des Auflösewalzengrundkörpers entspricht oder der bis maximal ± 5% vom Durchmesser des Auflösewalzengrundkörpers abweicht und die Drahtrolle lose auf eine Trägervorrichtung geschoben wird und mit dieser in eine galvanotechnische Anlage eingebracht wird, wobei in der galvanotechnischen Anlage die für das chemische Entgraten eines Rohdrates und das Nickel-Diamant Beschichten (a) einer garnierten Auflösewalze üblichen Verfahrensschritte ablaufen und der Garniturdraht aus der galvanotechnischen Anlage entnommen wird.
