Pre-positioning for cylindrical objects
Centror-L/PL checks the angular and transversal position of cylindrical objects and carries out a perfect positioning before printing.
Centror ensures a great register precision when sequential printing processes are executed.
Thanks to Centror-L/PL it is possible to make the pieces registration without any mechanical device.
This solution ensures the increasing of the machine productivity and the accuracy of the printing register.
Centror-L/GL analyzes the sidewall surface of an object in rotation to perform a real time orientation.
Plastic tubes, jars and bottles are the typical objects that require this special solution.
The reference mark could be the following ones:
- material seem
- screw thread
- previously printed decoration
