PCT No. PCT/SE90/00044 Sec. 371 Date Sep. 6, 1991 Sec. 102(e) Date Sep. 6, 1991 PCT Filed Jan. 19, 1990 PCT Pub. No. WO90/08231 PCT Pub. Date Jul. 26, 1990.The invention relates to an elongated floating barrier for use in controlling and concentrating substances floating on a liquid surface, preferably oil floating on a water surface. The barrier comprises a front shield towards the front surface (2) of which the substances are deposited and transported sideways along the shield as the barrier is moved relative the liquid surface. The front shield is inclined in such a way that its upper edge (5) is abaft its lower edge (6) and a towing means (4) is attached to the lower edge of the shield and arranged to give a mainly horizontal pull in the barrier when it is moved relative the water surface. The deep-going of the front shield and its inclination relative the water surface are regulated by a buoyant member (7), which is extended along the back (3) of the front shield and the lower face (8) of which is connected with the lower edge (6) of the front shield and extended in a backward upward direction so that it intersects the water surface when the barrier is in operational position.
