Brush with a rotatable axle. Around the perifery of the brush axle (2) are arranged a number of stiff bristles or tufts (5) of bristles in helical first rows (3), well separated from each other, at least the outer bristles of said first helical first rows, mounted close to the one end (6) of the brush axle, extending (s) past said end, preferably because at least those bristles of the first helical rows which are mounted close to said end (6) of the brush axle form an angle to the radial plane of the brush axle, so that the bristles extending past the axle end may reach into corners next to walls and similar obstacles, and as the brush is rotated may feed the sweepings forwards and sideways away from the obstacle. The invention relates also to a brush roller equipped with a brush of the described type, mounted at one of its ends. |
