Mst common areas in off set printing are mısfeeds; this is due to static charges being generated on the substrate as friction occurs as one sheet is dragged across the top of another. This can also lead to BLOCKING, where all the sheets just stick together and no feeds taker place.
 

 

 

By fitting PULSElectronic ionısıng nozzles to the stack, as the top sheet is grabbed to feed the machine, a blade of ionised air is blown between the top sheet and the penultimate sheet, which eliminates the charge and prevents blocking, sticking and jamming.

 





In printing machines, when rolled plastic film is started to be unwrapped, machine begins to be charged with static and with the fractions of film on the rollers are added, occurance of high static charges on the film can be seen.
It should be considered that static charge on the surface can cause film to slide left or right on line, static electric attracted dust particles to stick on surface, decrease the quality of printing,operator to be electrically shocked,machine?s electronic hardware to be harmed and most importantly paint to catch fire and explode in which static charge shocks are near the printing zone.

PULSElectronic Anti static bars will ensure film to reach printing cylinders clean and purified from static electric, if they are applied on the untying unit?s output bidirectionally as seen in the picture.Two anti static bars which is placed on wrapping unit?s input will prevent problems that occurs in input region because of static charge.
