A new computerized control system designed for packaging machines. This control system can be installed on any dieless packing machine. The advances achieved by this control system are: High speeds are achieved by synchronizing the machine index cycle and tooling controls, permitting the prestart of tooling before the end of the index cycle; because the motor speed is monitored and profiled by the computer continuously, faster machine speeds can be achieved while maintaining the minimum machine jerk; total index time savings; diagnostics which dramatically reduce machine down time as a user friendly hard-copy print out is produced describing and pinpointing locations of malfunctions in the timers, tooling, and motor performance; access to all timer control settings through easy to use thumbwhell switches. In addition, a new arrangement of the tooling stations is used, allowing for the increase of per cycle capacity several times the capacity of the prior art. The sealing station includes an initial sealing substation where no vacuum operation is performed, and a final sealing substation where a vacuum operation of considerably reduced requirements of time is carried out.
