DUO#DeDust® – Web & Corr – High-Performance Web Cleaning for Corrugated Printing, Flexographic Printing and Digital Printing
Highly efficient contact web cleaning for stable print quality, reduced machine downtime and measurably increased productivity.
Challenges in Web Cleaning
In corrugating plants, both fine paper dust and larger paper particles are generated. These contaminants may either remain loose or adhere mechanically to the web, particularly in cases of poor cutting quality. For this reason, Duo-Technik relies on contact web cleaning systems to ensure reliable particle removal.
In flexographic printing systems for paper substrates, paper abrasion generates dust that accumulates both in the printing environment and on the printing plates. This leads to quality issues and increased downtime caused by frequent plate cleaning.
In digital printing on paper substrates, paper dust can also accumulate inside the print heads. As a result, the print heads must be cleaned regularly or, in severe cases, replaced.
In all these applications, the integration of a DUO#DeDust® web cleaning system significantly improves process stability and production reliability.
Operating Principle of the DUO#DeDust® Web & Corr Systems
The DUO#DeDust® Web System combines physical force with electrostatic discharge:
- Targeted contact: The cleaning unit is designed to mechanically dislodge particles that adhere to the web during the cutting process.
- High-performance ionization: Neutralizes the static charge on the web to eliminate the attraction of fine dust.
- Vacuum extraction: A powerful extraction system immediately draws the loosened dust into the filtration system.
Benefits of DUO#DeDust®Web & Corr
- Significantly improved print quality through reduced particle contamination
- Extended cleaning intervals for printing plates and digital print heads
- Higher machine availability with fewer unplanned stops
- Gentle cleaning even at high web speeds
- Easy integration into existing production lines
- Sustainable reduction of waste and maintenance effort
By integrating web cleaning directly into the production process, overall equipment effectiveness increases and stable production conditions for high-quality products are ensured.
Typical Applications of DUO#DeDust®Web & Corr
DUO#DeDust® Web and DUO#DeDust® Corr systems are used wherever dust and fibre particles can negatively affect process stability and print quality.
Typical applications include:
- Corrugated board production lines before flexographic printing
- paper and board processing machines
- High-speed flexographic printing machines
- Digital printing systems
- Converting and downstream processing lines
Inline dust removal is particularly effective in high-speed applications and environments with significant dust generation.
Thanks to their flexible integration concept, DUO#DeDust® systems are suitable for both new installations and retrofit projects in existing corrugated and paper production environments.
