Abstract
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).
