The core of the profile is formed by granular material fed to station from a hopper through the interior of a hollow duct which is essentially vertically disposed, above the station, so that the granular material is moved under the influence of gravity. The exterior surface of duct is profiled and the skin-forming materials for the profile are guided by the profiled surface to the die station. The skin forming materials are runs of cloth. The pultruded profile may be tubular or hollow so that it has both an external surface and an internal surface in which case the internal surface incorporates a further resin bonded cloth fed to the interior of the die station over the external surface of a mandrel.
