ESD & Contamination Control On Re-Winders With Lay-On Rollers

Download PDF


Very high static charges are generated on the plastic web during the unwinding and rewinding process. This can cause various problems for converters and their customers, such as:

  • Unpleasant shocks to operators
  • Dust attraction, leading to contaminated stock
  • Poor quality wound reels which can be difficult to fit onto machines and may cause feed problems
  • Structural damage to coatings
  • Exposing edges to damage - incorrect tension causing core crushing or core drop out


The most effective solution is to use Meech AC technology, with model 915 bars positioned as shown.

The positioning of a Model 915 bar at the unwind will provide control of static charges. 

However, depending on the direction of the wind, clockwise will neutralise both sides of the material, while anti-clockwise can only neutralise one side. This direction may leave a small residue charge.
