Abstract
A control system for a glassware forming machine determines the machine speed in accordance with the physical characteristics of the molten glass and the type of glassware being formed. The control system is loaded with timing data representing predetermined forming steps and a machine cycle speed and a control program for generating control signals to the machine forming mechanisms for forming the selected type of glassware. As the machine is operated, one or more physical characteristics of the molten glass entering the machine are sensed and utilized by the control system to adjust the machine speed to an optimum value. The control system also can utilize signals representing the operation of the forming mechanisms to adjust the timing within the machine cycle.
