According to the invention, a method is used for surface treatment of ob¬ jects (7), wherein wire rollers (15) are caused to contact the object (7) to exert a blow or hammer impact, which wire rollers (15) partly rotate (8), partly revolve (12), partly move (14) transversely to the object (7) on the belt (11). This ensures an effective and completely uniform treatment (knocking-off, cleaning) of surface coatings, including oxide layers, by a non- abrasive or non-cutting treatment, but solely an impact stress. A rotating wire roller (15) may advantageously be used, which roller is composed of wire elements (1 , 2, 3) mounted on stays (4) so that they may bounce slightly rearwards (9) at impact, and otherwise remain in the same position by means of the centrifugal force and the engagement of the wire end with an adjacent stay (4).
La présente invention concerne un procédé utilisé pour le traitement de surface d~objets (7), des rouleaux à fil (15) étant amenés au contact de l~objet (7) pour exercer un choc de martelage ou de soufflage, lesquels rouleaux à fil (15) ont un mouvement de rotation partiel (8), un mouvement de révolution partiel (12) et un mouvement transversal partiel (14) par rapport à l~objer (7) sur la courroie (11). Un traitement efficace et totalement uniforme (piquage, nettoyage) des revêtements de surface, y compris des couches d~oxyde, est ainsi assuré par un traitement non abrasif ou non coupant, uniquement sous l~effet de l~effort au choc. Un rouleau à fil (15) peut être utilisé avantageusement, lequel rouleau à fil se compose d~éléments de fil (1, 2, 3) montés sur des supports (4) de sorte qu~ils puissent légèrement rebondir en arrière (9) au moment du choc ou alors rester dans la même position sous l~effet de la force centrifuge et de l~engagement de l~extrémité du fil avec un support adjacent (4).
