This machine has been purposely designed to perform simple operations such as lip reverting or leakage testing (with pressure differential method) on single component closures at high speed rates. It is equipped with a PLC system and an AC Converter (Inverter) that makes the machine adapt its speed automatically with the caps feeder’s production. The “Human/Machine Interface” is a “touch screen” through which all functions and parameters can be displayed, accessed and modified. All movements are mechanic (no slow and uncertain pneumatic devices except for few secondary functions not directly related with the main operation).
