Discharging System
This highly effective DC static elimination system has been available to the market for the last 15 years and removes troublesome static charge in winding, slitting, laminating and blown film processes. Free ions (both positively and negatively charged) are deposited at high speed onto the surface of the substrate during the winding process and the positively charged ions on the surface of the substrate recombine with the predominantly negatively charged ions coming from the discharge bar.
The high performance EST-DC-LDS has an effective range of approximately 20–800 mm (0.79″–31.5”) and does not need to be adjusted to suit the characteristics of differently charged substrates. Using this special DC technology, this static elimination system can be used to remove all combinations of static charge and there is no further need to use AC discharge systems on the machine winder.
