ACA RoQ Inline
Automated roll hardness analyzer enables in-line roll inspection for uninterrupted quality control
ACA RoQ Inline is a fully automated roll hardness analyzer designed to be installed directly into the production line. It measures every roll after the winder and before packaging—without manual intervention.
Developed for demanding industrial use, RoQ Inline combines precision sensors, automated data collection, and intuitive software to deliver actionable insights. With this advanced tool, mills gain full control over roll quality, reduce waste, and ensure optimal performance from start to finish.
Real-time quality monitoring with non-destructive measurement
Improved roll consistency and reduced customer claims
Early detection of winding issues before they escalate
Easy integration into existing production lines
Key benefits
Early detection of roll defects
Spot roll quality deviations—such as soft edges or hardness variations—before they lead to runnability issues or customer complaints.
Consistently high roll quality
Reliable, real-time measurements allow for fine-tuning of the winding process, ensuring uniform roll structure and reducing variability.
Fewer returns and reclaims
Maintaining roll quality throughout production minimizes the risk of product defects, lowers waste, and enhances customer satisfaction.
Ready for smart manufacturing
Fully compatible with digital production systems, ACA RoQ Inline analyzer support automated quality control and help drive continuous improvement through data.

Key application areas
Paper & Board
-
Printers and converters report fewer quality complaints when roll hardness is monitored, and profile control helps optimize the winding process.
-
Hardness profile measurement reduces customer complaints and improves control over the thickness profile, especially where traditional sensors struggle due to pulp impurities.
-
Accurate profile measurement is essential, as various converting steps and the high added value in the production chain require consistent quality.
-
Fewer complaints from downstream users are achieved through better profile control and calendering optimization, especially since customer rolls are typically wound very tightly, making hardness consistency critical.
-
Monitoring roll hardness helps reduce printer complaints and enables better calendering and profile control, supporting overall roll quality.
-
Precise calendering control is required to meet the high quality standards of the label industry, where profile accuracy is extremely important.
-
By improving profile and moisture control, converters benefit from better dimensional stability and fewer quality-related issues.
-
Even roll profiles are essential due to the low flexibility of these grades, making accurate profile measurement a key requirement.
Converters
-
Consistent roll profiles reduce production stops and quality issues—see our customer case study for real-world results.
-
Monitoring roll hardness ensures the quality of incoming rolls and supports control across various production steps.
-
Good roll profiles are crucial for multilayer, high-value products that include sensitive elements such as barcodes, QR codes, and ID marks.
-
Profile control is particularly challenging with thin films, and since the materials are expensive, minimizing waste is vital.
-
Ensuring accurate profiles on narrow incoming rolls is critical, as local variations can cause significant quality issues.
-
Controlling roll profiles before lamination improves bonding performance and helps avoid material waste.
Plastic Films
-
Profile control is challenging with thin, high-performance films, but essential for minimizing waste and maintaining consistent quality in these expensive materials.
