Static electricity may be the cause of malfunctioning of high speed printing presses. At the feeder sheets may stick together with mis-registration and machine stop as a result. Ionising air knives blowing in paper direction to separate the top sheet from the stack with ionised air. The top sheet is now fed into the machine and can be neutralised in open air when passing underneath the bar, mounted on top of the stack. Single or double side neutralisation at the delivery section will ensure a neat stack.
Each individual emitter pin of this anti-static bar is coupled capacitively to the high voltage. You will therefore not get an electrical shock when the emitter pin is accidentally touched. Another advantage is that the bar continues to function properly when a number of emitter pins are short-circuited, for instance due to heavy fouling.
This type of anti-static bar, a more powerful version of the EP-Sh-N is highly effective and, with its long range, ideal for neutralization of static electricity on materials when the distance varies. Under certain conditions the maximum distance may even be as large as 600 mm.
A type MEB shockless anti-static bar combined with an airknife come in standard lengths. The compressed air is blown across the high-voltage points over the entire width and amplified by the ambient air carried along. The air flow is saturated by the positive and negative ions produced by the anti-static bar.
