A control for use with a glass forming machine which is controlled by a programmable sequencer which defines a machine cycle having a set cycle time. A computerized model of a mathematical representation of a network constraint diagram of the unwrapped bottle forming process is provided for determining whether, with the following inputs: the time in an unwrapped bottle forming process for each displacement to occur; the machine cycle time; the motion durations of each of the mechanisms from the retracted position to the advanced position and from the advanced position to the retracted position and the collision zones between interfering paths, a collision will result between the gob, the parison, the bottle or any mechanism. |
