ABSTRACT:
The invention relates to a method of coating a surface of a fiber blanket comprising forcing a plurality of probes through the fiber blanket until the probes extend beyond the surface to be coated, so that holes are formed in the fiber blanket, applying fluid coating material on the surface to be coated, retracting the probes from the fiber blanket, allowing the coating material to flow into the holes during the retraction of the probes, forming heads of the coating material at the uncoated surface of the fiber blanket, and allowing the coating material to harden. The invention relates moreover to an apparatus for carrying out this method. The coated fiber blanket obtained by the method according to the invention has the advantage that the hardened layer of coating material is firmly anchored to the blanket.
