Comment Schematic explanation of electrostatic charge build-up due to friction in a R2R process


Due to the contact moment be- tween substrate and roller, elec- trones are transferred to the roller.


The roller will be negatively charged, and the substrate positively charged. There is an electrical imbalance: static electricity.


The more contact moments between substrate and roller, the more build up of electric charge. This will cause process instability.

Once static is under control, the benefi ts are immediately visible across the production line: • Fewer jams and unplanned stops • Improved web handling and tracking


• Consistent stacking and separation • Reduced contamination from dust • Less wear on sensitive components These improvements apply not only to printing


and converting, but also to nonwoven processing, fi lm & foil, textile fi nishing and fl exible packaging. In all these applications, stable material behavior is essential for reliable production.
