This ensures that an in Feed direction of the wire end at the front in one direction perpendicular to the feed direction of the electromotively controlled Brought roles and in a corresponding, arranged there Device can be subjected to a machining process, the piece of wire is then withdrawn from the device and in the feed direction of the electromotively controlled rollers through the leadership block can be promoted to full Length to exit on the other side of the guide block then the rear one in a second machining operation To feed the end of the piece of wire to the processing device, by conveying the piece of wire backwards and into the Direction perpendicular to the feed direction of the electric motor controlled roles in which the Processing facility is located. The so finished The piece of wire is then in the conveying direction from the Wire guide device conveyed out.

The conveying and processing operation according to the invention can be so it is particularly easy to carry out when one of the two Wire guides that convey the wire in one direction perpendicular to the feed direction of the electromotively controlled Rollers allow the wire to be fed forward causes and the other of these two wire guides one Guidance of the wire fed backwards causes. Advantageous is there when the wire guides that promote the Wire in a direction perpendicular to the feed direction of the electromotive controlled rollers allow a curved Have guideway.

According to a preferred embodiment of the invention Wire guide device is the guide block for adjustment a predetermined one arranged in a certain plane Height adjustable wire guide. To be there Ensuring a precise setting is the altitude of the guide block according to a preferred embodiment controllable by electric motor.

The from the perpendicular to the feed direction of the Device arranged by electromotively controlled rollers performed processing can be very different Be nature. In a preferred embodiment, is a Stripping wire ends in connection with striking Wire end sleeves provided. However, these two operations can can also be done separately. Are conceivable for example, treatments with hard or soft solder.
