<p>The invention relates to a brush structure for removing impurities, especially oil, from the surface of water. The brush of the brush structure comprises a big number of bristles (2) , whose ends form in the direction of rotation of the brush a substantially continuous brush surface (3) , which is limited by edges (4) in the transverse direction. In addition, the brush structure comprises, at least partly beneath the brush in the vicinity of the brush surface, a jacket (5) preventing exit of impurities from the bristles and directing the impurities forward along with the bristles. According to the invention, a part of the bristles are shorter (1) so that recesses (6) transverse in the direction of motion of the brush are formed in the vicinity of them in the brush surface, the recesses extending at least to the one edge (4) of the brush surface thereby forming water collection cavities together with the jacket (5) , along which cavities the water separated from the bristles is allowed to flow out prior to the removal (7) of impurities from the bristles.</p> |
