Abstract: An apparatus for working the surfaces (4) of traffic areas (5) comprises a oll (16) rotatably drivable about a substantially horizontally extending axis (17), this roll carrying along its periphery working elements acting on the surface (4) to be treated. The roll (16) is supported with respect to the frame (1) of the apparatus by adjustable servo members (21) and is additionally tiltable about an axis that is perpendicular to the axis of rotation (17) of the roll (16) and is oriented essentially horizontally. Furthermore, a rotary brush (101) is disclosed for the working of traffic areas and for removing layers from the surface, exhibiting a brush core (102) with working elements attached to the latter.

Abstract: Several holding members (1) are arranged over the outer surface of the br core in radial and axial distribution for working elements (2) of roller brushes to treat traffic areas, especially in order to remove, for the surface of the latter, coatings such as dirt, snow, ice, paint, abraded rubber, or the like, and the working elements (2) are retained so that they are pivotably movable with respect to the brush core about axes in parallel to the axis of rotation of the brush, the working elements (2) being attached to the holding members (1) in the zone of a radially outwardly located head (3) of the holding member (1).
