Technidyne ACA RoQ™ Inline Roll Hardness Analyzer

Next-level roll hardness analysis—fully automated and inline

The ACA RoQ™ Inline Roll Hardness Analyzer is a cutting-edge solution designed for seamless integration into production lines. It enables manufacturers to measure every roll immediately after winding and before packaging—without manual intervention. All measurements are automated, data-driven, and non-destructive.

Future-ready roll hardness measurements

Engineered for demanding industrial environments, the RoQ™ Inline combines precision sensors, automated data collection, and intuitive software to deliver actionable insights. Mills gain full control over roll quality, reduce waste, and ensure optimal performance from start to finish.

The system provides continuous roll quality monitoring during production, delivering real-time data on roll hardness profiles and enabling automatic anomaly detection. It supports complete roll documentation and traceability, enhancing customer confidence and supporting quality certifications.

Roll hardness profiler essentials

When you need to define a good or bad roll it’s essential to know the roll hardness profile. A good paper roll is wound with uniform or diminishing hardness from the core to the outside of the roll.

Whether you’re working with paper, paperboard, cardboard, corrugated materials, films, or non-wovens, rolls that are wound too soft or too tight can lead to problems. Rolls must be wound to support their own weight and withstand impact and compressive loads during shipping and handling.

The benefits of automated roll hardness profile testing

With the ACA RoQ™ Inline Roll Hardness Analyzer, you can:

• Quickly identify roll issues: Detect deviations such as soft edges or inconsistent hardness before they cause runnability problems or customer complaints.
• Ensure consistent roll quality: Real-time, reliable measurements allow for fine-tuning of the winding process, resulting in uniform roll structure and reduced variability.
• Save money and protect your reputation: Fewer roll quality complaints mean less waste and happier customers. Maintaining roll quality throughout production minimizes defects and boosts satisfaction.
• Automate quality control: Fully compatible with digital production systems, the RoQ™ Inline supports automated quality control and drives continuous improvement through data.
