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.
