Web cleaning

Static electricity is generated when paper and plastic webs, or sheets, are being processed. Dust particles adhere electrostatically to the surface. Quality deteriorates due to this type of contamination, particularly when the products have to be printed. CleanION web cleaning systems have been designed to neutralise static charges and, at the same time, to remove particles, even at higher velocities! Each CleanION system is designed to meet specific production requirements. A variety of vacuum hood configurations and dustcollectors are available to ensure maximum cleaning and static neutralisation for each application. For all web widths there are vacuum hoods for non-contact cleaning or contact (brush) cleaning.

Vacuum hood configurations are adapted to their individual need. Three basis principles are used:
1) High vacuum /low volume full contact cleaning
2) Medium vacuum/medium volume contact cleaning with air assist
3) High vacuum/high volume non contact cleaning with balanced air assist

A vacuum hood is constructed with a special shaped suction slot. Prior to the suction slot the substrate will be neutralised by an anti-static bar. This removes the adhesion force caused by the static electricity and creates an ideal basis for the cleaning. Contact systems use a soft brush to loosen particles from the substrate prior to cleaning. Contact cleaning with air assist and non contact cleaning systems use an air nozzle to blow against the movement of the substrate to force particles into the suction slot. Non contact cleaners use a closed-loop blower system for the vacuum and blowing air. The web is guided through the double sided cleaning heads that provide excellent web guidance.

Dustcollectors are available for each specific system ensuring maximum cleaning efficiency. All dustcollectors are equipped with durable three phase 400V motors. Please contact Simco-Ion Europe or a Simco-Ion representative for a detailed advice tailored to your specific situation.
