A conveyor (2) for conveying a plurality of moulds (M) along a plurality ofstations (S1, -S 16). Each mould (M)carries an electronic identification device (T) including memory devices (4).Each station (S1 -S 16) is provided with an electronicunit (A-E) including a processor (9), having memory devices (10) and at leastone antenna (15), and designed to read and/or writeinformation or data from or to the memory devices (4) of a mould (M). Aninitial input station(S1) transfers or writes to the memorydevices (4) information identifying the products (P) to be formed in the mould(M), the electronic unite (C) of each additionalsta-tion(S3, S6,... ) being capable of selectively modifying the mode ofexecution of at least one of its operations, in accordance withoperating information read from the memory devices (4) associated with themould (M) passing through it.
