TCU20-M4 SERIES: Corona Treatments for Printing and Coupling

One-side corona refreshment systems for increasing the wettability of metallised and flexible insulation films on high speed printing and laminating machines (up to 550 m/min).
Each system consists of a TCU20-M4 one-side discharge unit, a GET electronic power generator, and an ozone extraction system.
The discharge station is designed to simplify all the most common use and maintenance operations: material insertion, air-gap calibration, and electrode cleaning.

Electrodes:
• 4 ceramic Cason electrodes with a large discharge surface and a custom design that aids cooling and ensures a long service life.
• Segregated in protective boxes with pneumatic opening-closing mechanisms for easy material insertion.

Treatment roller:
• Statically and dynamically balanced
• Coated with a special custom coating by Cason (for metallised materials)
• Predisposed for motorisation

Ozone suction system:
• Designed to keep the discharge electrodes well cooled and very clean.

Safety, sensors, and signals:
• The emergency stops, mobile guards, and electrode boxes are monitored by dual channel safety switches.
• Dedicated sensors for controlling the rotation of the treatment rollers and the extraction flow.
• Signals: Acoustic buzzer, 3-colour light column.

Main construction materials:
• Stainless steel and aluminium.
