Disclosed is a device for treating electroconductive endless material (3) such as wire, especially copper wire. The inventive devices treats said material during the movement of the endless material and in the extension direction thereof and can be used for heating or annealing the endless material or for cleaning the surface thereof. The inventive device comprises a contact device (15) for electrically contacting the moved endless material (3) and an electrode arrangement (17) which is arranged at a distance from the endless material (3) and which at least partially encompasses the endless material. A gas discharge chamber (11) is arranged between the endless material (3) and the electrode arrangement (17) and is filled with a reaction gas. A voltage is impressed across the contact device (5) and the electrode arrangement (17) and in said gas discharge chamber (11). An electric gas discharge can thus be produced in order to treat the endless material (3).

L'invention concerne un dispositif permettant de traiter un matériau continu (3) électroconducteur, tel que du fil, notamment du fil de cuivre. Le traitement intervient pendant le déplacement du matériau continu dans le sens où il s'étend à travers le dispositif. Ce dispositif s'utilise pour chauffer, rendre incandescent le matériau continu ou en nettoyer les surfaces. Ce dispositif comprend un dispositif de contact (15) pour établir un contact électrique avec le matériau continu (3) animé, ainsi qu'un système d'électrodes (17) disposé à distance du matériau continu (3) et l'enserrant au moins en partie. Une décharge gazeuse électrique destinée à traiter le matériau continu (3) peut être produite dans un espace de décharge gazeuse (11) situé entre le matériau continu (3) et le système d'électrodes (17) et rempli d'un gaz de réaction, par application d'une tension électrique entre le dispositif de contact (5) et le système d'électrodes (17).
