OIL FENCE

Oil fence especially adapted for the defining of impurities on a water surface and made of a web of cloth shaped material. The web exhibits alternating connected portions and multiple layer portions made in such a manner that between the layers of the multiple layer portions pockets and/or channels are formed, which are defined by the single layer portions, in order to receive for one thing float bodies for the support of the oil fence in water, and for another thing sinking weights in order to give the oil fence the intended upright position in the water. The present cloth shaped web comprises a preferably impregnated and/or coated textile material, which is woven with alternating single layer portions forming said connected portions and portions with at least two layers, between which said pockets and/ or channels are formed. The single layer portions are by means of a per se known weaving technique shaped from the interwoven weft of the converging layers of the adjacent multiple layer portions, thereby obtaining an extremely strong connection of said portions.
