Uniformity
Special Electrode Design
Uniform distribution of the discharge to ensure consistent treatment quality.
High Performance
Up to 3,500 mm
Designed for processing wide sheets and plates.
Reliability
Premium Facility
Sturdy construction, ozone-resistant materials, and components designed to ensure long service life and uninterrupted production.
Efficiency
Gap Self-Adjustment
Automatic compensation for thickness variations without manual adjustments.
Designed for modern processing lines for semi-rigid sheets and plates
Consistent and stable treatment even on very thick materials
The production lines dedicated to semi-rigid sheets and plates require corona treatment systems capable of ensuring uniform discharge, high reliability, and production continuity even when processing materials of varying thicknesses.
Me.Ro systems are designed to treat materials up to 3500 mm in width, with the ability to operate on one or both sides while maintaining a constant Corona dose throughout the entire production cycle.
The combination of a rigid structure, high-performance electrodes, and automatic control of theAir-GAP ensures consistent treatment quality and maximum operational stability.

Electrodes designed to ensure uniformity and precision
Maximum Air-GAP stability throughout operation
The special aluminum electrodes are designed to maintain a uniform discharge distance across the entire width of the material.
The unique mounting system connects the electrodes to the structure at multiple points along the top beam, allowing for free thermal expansion without altering theset Air-GAP.
Upon request, it is also possible to install stainless steel electrodes for specific applications.
Segmented Electrodes and Air-GAP Self-Regulation
Maximum flexibility for materials of various sizes and thicknesses
The system can be equipped with segmented electrodes, which allow each segment to be moved away from the corona roller individually.
Adjusting the partialization is quick and easy during production changeovers, while maintaining the set position even during operation.
The exclusive self-adjustingAir-GAP automatically compensates for variations in sheet thickness, eliminating the need for readjustments and ensuring consistently uniform treatment.

A structure designed to ensure long-term reliability
Integrated security, simplified maintenance, and continuous operation
The highly rigid structure ensures the stability of the Air-GAP and helps maintain consistent processing quality.
The pneumatic opening of the hood facilitates material feeding and improves accessibility during maintenance operations.
The Corona rollers are statically and dynamically balanced and feature a speed sensor. Safety switches automatically cut off the power supply if the hood is opened, while electromagnetic compatibility complies with the standards EN 55011 and EN 50082-2.
