Sheet Corona Treatment
Corona Treater Model CPL (Plastic Sheet Industry)
The corona system able to solve all your problems in the carton plast and sheet industry. Installable on extrusion lines and printing lines, it gives you the possibility to treat materials up to 20 mm of thickness. The particular design of the electrodes (any electrode is kept in working position through big insulators connected to a strong central beam) together with the stiffness of the structure guarantees an absolute uniformity of the gap during running.
MAIN CHARACTERISTICS
- Able to treat one or two sides of the web
- Web width up to 3500 mm
- Specific power (energy density) kept strictly constant during running
- Corona roller in aluminium covered in special silicon sleeves (other coatings can be supplied upon requests)
- Special electrodes in aluminium. The construction is made to guarantee uniformity of the air gap. The electrode is in fact connected to the structure not on the lateral sides but in many points on the upper beam of the station. This allows a free expansion when running
- Possibility to have segmented electrodes. The segments can be individually moved away from the corona roller. The construction system is done in a way that allows an easy and fast setting of the partialization during a production change and moreover guarantees an absolute stability of the chosen position of the segments during running
- High Stiffness of the structure holding the electrodes. Another important point for the stability of the air-gap
- Easy air-gap regulation from outside the hood containing the electrode
- Electrodes opened pneumatically for easy webbing up
- Rollers statically and dynamically balanced
- Speed sensor mounted on the corona roller
- Safety switches shut down the power supply in case of accidental opening of the hood containing the electrodes
- Electromagnetic (EMC) compatibility in accordance with EN-55011 and EN 50082-2 standards
OPTIONALS
- Possibility to have the overpressure version for explosive proof environments
- Possibility to install also full electrodes in stainless steel
