An individual section (IS) machine glassware forming system (10) includes an individual section machine (20) with a plurality of individual sections (20a, 20b, 20c, 20d, 20e, 20f, 20g, 20h, 20i, 20j, 20k, 20l, 20m, 20n) for receiving gobs of molten glass and forming the gobs into articles of glassware. A gob feeder (12, 14, 16) presents gobs of molten glass, and a gob distributor (18) feeds the gobs to the individual machine sections in sequence. Operation of the machine sections is synchronized to operation of the glass feeder by generating (at 40) a feeder index signal indicative of presentation of glass gobs at the glass feeder. An electronic machine timing circuit (42) includes facility for electronically generating a machine index signal for synchronizing operation of the machine sections with respect to each other. Separation in real time between the feeder index signal and the machine index signal during system operation is determined and stored in units of time. Upon initialization of operation of the system after shutdown for any reason, this stored time is automatically retrieved, and timing of the machine index signal is automatically adjusted relative to the feeder index signal to equal this stored time. <IMAGE> |
