In a pressing machine for the manufacture of glass articles, which comprises, a base; a gyratory table composed of mold supporters equidistantly laid out around the table, thereby carrying the molds from one station to the next as the table gyrates intermittently, said table comprising a number of stations, among which are stations of charging, stations for pressing and cooling articles, extracting stations and stations for the cooling of the molds, wherein such stations includes a series of mechanisms; means to drive the rotating table coupled to said table to rotate the same; and a feeder in combination with said machine which provide a gob of glass to the station of charging by each cycle of the machine, a method and an apparatus is provided to controlling the cycle of operation of the machine and the operation of the diverse mechanisms including: a sensor to determine the instant in which a gob of glass is cut from said feeder and position sensors to detecting the real position of the diverse mechanisms of the machine, to derive signals representative of the movements of each mechanism. Control means for processing the signals provided by the sensors in order to start the machine cycle by each cut of gob and for determining the indexing of said table and the operation of each mechanism in accordance with the time determined by said control means. And a valve block connected to said control means to actuate the mechanism in base to the signals that are send by said control means.
