As Fig. 2 shows that is in accordance with the Fig. 1 and 2 selected wire 1 already left of the superimposed remaining wires 2-5 in the position of discharge from the device. The horizontal method of the selected pair of roller carriers 10-19 is made possible as follows: Each roller carrier 10-19 is connected to one of the legs 26 ', 26 "of a U-shaped pivoting arm 26, which legs 26' in the vertical guide 25 'are vertically movable The other leg 26 "of the pivoting arm 26 is also vertically movable in the vertical guide 25 'and pivotally guided about an axis 26'''. Once that with the wire selected from all the wires 1-5 (1, Fig. 1 . 2 ) equipped pair of roller carriers (10, 11, Fig. 1 . 2 ) reaches the height level of the production line, the pivot arm 26 is pivoted about the axis 26 '''' in the vertical position, and the axis 26 '''can enter the horizontal guide 25 "and the roller carriers (10, 11, Fig. 1 . 2 ).

Mit Hilfe der Vertikalverfahreinrichtung 24 und der Horizontalverfahreinrichtung 28 kann der zu verarbeitende Draht aus der Vielzahl Drahte 1-5 in der erwähnten Weise ausgewählt und in die Produktionslinie verbracht werden.By means of the vertical traversing device 24 and the horizontal traversing device 28, the wire to be processed from the plurality of wires 1-5 can be selected in the manner mentioned and brought into the production line.

In Fig. 2 ist im übrigen ein Getriebe 29 für die Vorschubrollen 22, 22' der Vorschiebeeinrichtung 21 mit einem Antriebsmotor 30 ersichtlich, welches ebenso wie die gesamte Vorschiebeeinrichtung 21 vom Gestell 25 getragen ist.In Fig. 2 is otherwise a gear 29 for the feed rollers 22, 22 'of the advancing device 21 with a drive motor 30, which as well as the entire Vorschiebeeinrichtung 21 is supported by the frame 25.

Die Vorschub- und Richtvorrichtung für Doppeldrähte, d.h. zwei nebeneinander in geringem Abstand verlaufende Drähte, unterscheidet sich von der in den Fig. 1 und 2 dargestellten nur dadurch, daß alle Richtröllen 20, 20' und die Vorschubrollen 22, 22' als miteinander verbundene oder einstückige Doppelrollen ausgebildet sind.The feeding and straightening device for double wires, ie two wires running next to each other at a small distance, differs from that in the Fig. 1 and 2 shown only in that all Richtröllen 20, 20 'and the feed rollers 22, 22' are formed as interconnected or integral double roles.
