ACA RoQ Handheld

Handheld roll hardness analyzer puts fast, flexible quality control in your hands

ACA RoQ is a portable and user-friendly device for measuring roll hardness on individual rolls. It is ideal for both parent reels before the winder and customer rolls after the slitting process.

  • Portable and easy to use for on-the-spot roll quality checks

  • Detects soft cores, edge softness, and hardness variations quickly

  • Ideal for both parent reels and customer rolls after slitting

  • Enhances quality assurance and reduces the risk of product returns

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.
