The process consists in moulding, between a perforated tube 1 and a concentric tubular mould 2, a mass 4 of sintered granular material with granules of prepolymerized resin, heating and pressing said mass 4 at the same time. The apparatus comprises a press in the form of a crown 5, coaxial with the mould 2 and perforated body 1, with fluodynamic pressure cylinder 10. The cylinder consists of a perforated body 1 intermittently linked to the outside of which there is a microporous layer 4. <IMAGE>
