Where is web cleaning with contact to the material webs applicable?
KELVA contact cleaners are suitable for removing contaminations on coated (glossed) paper, film and foil with low dust levels, web speeds up to 400 m/minute and web widths up to 2.500 mm. They are operated pneumatically and are available for cleaning of one or the two sides of the material web.
Specially developed polymer rollers lift and transfer contaminations from the web surface to easily replaceable adhesive sheets. The polymer roller is designed to give a very good contact to the web – even at low pressure. The active static discharger, located after the rollers, ensures that the web does not re-attract dust after passing through the cleaner.
