ABSTRACT:
An I.S. Machine is disclosed which includes a structure displaceable from a start location to an end location and a motor for displacing that structure. A control controls the operation of the motor to displace the structure and the speed of displacement can be varied by changing inputs to the control. A fixed period of time from a datum to the ideal time when the structure will be displaced to its end location is set and compared with an actual period and a selected input to the control is provided for changing the speed of the structure to reduce the difference.
