The method and device relate to a method and device for continuous surface treatment of an elongate filiform object by means of plasma created by an electric discharge at ambient pressure. The device (100) comprises a tubular body (2) wherein a channel, which is at least partially open at the two extremities thereof, allowing said elongate object (A) to pass according to an axis of travel which is substantially parallel to the longitudinal axis of the channel (1), is created. Said device also comprises means (3) for generating a neutral plasma flow at a given angle in relation to the longitudinal axis in at least one part (10) of the body (2), and means for confining the plasma flow in said part (10), at least while the elongate object crosses through said part of the body of the channel. The device also makes it possible to vary the effect of treatment by adding the requisite additives to the plasma and/or by direct addition to a treatment area and by using the different plasma areas containing particles having a different level of energy.
Le procEdE et le dispositif concernent le traitement de surface en continu de la surface d'un objet allongE filiforme au moyen d'un plasma crEE par une dEcharge Electrique sous pression ambiante. Le dispositif (100) comprend un corps tubulaire (2), dans lequel est mEnagE un canal (1) au moins partiellement ouvert A ses deux extrEmitEs pour le passage de l'objet allongE (A) selon un axe de dEfilement sensiblement parallEle A l'axe longitudinal du canal (1), des moyens (3) pour gEnErer un flux de plasma neutre sous un angle dEterminE par rapport A l'axe longitudinal dans au moins une partie (10) du corps (2), et des moyens pour confiner le flux de plasma dans cette partie (10) au moins pendant que l'objet allongE traverse cette partie du corps du canal. Le dispositif permet aussi de varier l'effet du traitement en ajoutant des additifs nEcessaires dans le plasma et/ou directement dans une zone de traitement et en utilisant les diffErentes zones du plasma contenant des particules dotEes de diffErent niveau d'Energie.
