The formation and dewatering take place in the presence of a cationic polymeric synthetic retention agent, preferably a cationic polyacrylamide, an anionic inorganic colloid and a polyaluminum compound. The process which is carried out at a stock pH above 5 gives an improved dewatering and an improved retention of fine fibres and optional fillers.
