At the in-feed an electrostatic charge is created that will cause the top sheets to stick together. This usually results in a paper jam and consequently a machine stop. Blowing with ionising air nozzles will flutter the top sheets separating them and neutralising the static charge so that they can be removed from the stack individually. Including a static neutralising bar, mounted just ahead of the paper stack, insures that the individual sheets move. Friction generated by the folding operation creates an electrostatic charge again, which will cause registration problems at the folding-pocket resulting in incorrect folds. An anti-static bar will eliminate the static charge, and eliminate folding problems. At the delivery end an anti-static bar will ensure a neat stack.
MEB anti-static bars are often used on production machines were short range ionisation is possible and where no moving machine parts are interfering the ionisation.
Each individual emitter point of this rectangular anti-static bar is coupled capacitively to the high voltage.
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.
Blowflex Easy is an in-line ionising air nozzle for neutralising and cleaning various surfaces. The nozzle is connected to a 24V DC power supply and incorporates all high voltage parts.
It is highly efficient due to a special patented high frequency high voltage generation.
