<p>The brush (4) has brush elements (8) of elastic material projecting from a rotary shaft (7), a longitudinal axis (15) radial to the shaft, and curved outer surface. The surface merges into two parallel side surfaces. These are connected by a flat ballast contact face (10), which encloses a 90[deg] angle with the side surfaces, and is located in front of the curved surface relative to the direction of rotation of the shaft.</p> |
