Corona treater model UUC (Converting industry).

The corona system able to solve all your problems in the converting industry. Installable on printing and laminating machines, it gives you the possibility to treat both non conductive and conductive materials ( such as aluminium foils and metallized films).
Speeds of production of 600 m/min have already been reached with this equipment obtaining great benefits for printing and laminating.


  • Able to treat one or two sides of the web.
  • Web width up to 2500 mm.
  • Specific power (energy density) kept strictly constant during running.
  • Corona roller in aluminium covered with conductive ceramic to guarantee a longer life and a great resistance to the ozone attacks.
  • Discharge bars in special ceramic material, protected by a sturdy aluminium housing.
  • Easy removal of discharge groups through fasteners for cleaning.
  • Easy air-gap regulation.
  • Discharge groups opened pneumatically for easy webbing up.
  • High voltage input studied to have a safe connection absolutely protected by dust.
  • Ozone exhaust system coming out on the transmission side in order to avoid any bending of the flexibles and a better estetic effect.
  • Rollers statically and dinamically balanced.
  • Speed sensor mounted on the corona roller.
  • Safety switches close down the power supply in case of accidental opening of the discharge groups.
  • Electromagnetic (EMC) compatibility in accordance with EN-55011 and EN 50082-2 standards.


  • Corona roller supplied with extended shaft for motorization.
  • Possibility of installation of nip roller.
  • Possibility to have the overpressure version for explosive proof environments.
