According to the invention, a method is used for surface treatment of objects (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).
A method for surface treatment of an object, which is preferably placed on a conveyor belt with a view to being advanced and treated by wires on one or more rotating wire rollers, characterized in that each wire roller (15) rotates (8) about a shaft (5) extending radially form a revolving shaft (13) which revolves (12), and wherein the revolving shaft (13) and the wire rollers (15) are moved transversely (14) to the conveyor belt (11) at the same time, so that the object (7) is treated from all sides with a uniform impact stress from the wires (1) on the wire rollers (15).
