Abstract: The subject-matter of the present invention is a method and an apparatus for collectively treating the surfaces of a plurality of objects.

Abstract: A method for removing a coating of a surface of a wheel. The wheel is provided with screw channels and with a centrally positioned hub opening. Each of the screw channels and the central opening is delimited by an area from which the coating is to be removed. Each of the areas extends annularly around one of the screw channels or around the hub opening. The method is implemented using a laser beam generated by a laser source. The method comprises the steps of positioning an extraction opening directly beneath a center of one of the screw channels or the central opening surrounded by the area, moving the laser beam over the area without masking the area (7) from which the coating is to be removed, and extracting gases and particles produced during the step of removing the coating directly through one of the screw channels or the central opening.

Abstract: The invention relates to a method for removing the coating of a surface, provided with a coating (8), of a wheel (1) provided with screw channels (6) and with a centrally positioned hub opening within one or a number of areas (7) from which the coating is to be removed, which areas extend annularly, in particular circularly, around one of the screw channels (6) and/or around the hub opening (8), the method being implemented using a laser beam generated by a laser source (12), characterised in that the laser beam is moved over the area or areas (7) of the surface from which the coating is to be removed, without limiting the area or areas (7) from which the coating is to be removed by additional means. Furthermore, the invention relates to a coating removal station (10) for implementing the method.
