Enhanced Roll Testing Accuracy

Film & Paper Roll Hardness Testers

Proceq RQ8000

✔ In stock

Roll testing based on position measurement and hammer penetration, minimizing roll surface damage and increasing accuracy.

  • Position-based instead of acceleration-based only
  • Minimization of damage through hitting velocity and shape selection
  • Reports can be saved to standard SD card

Applications:

Large, midsize and small paper rolls / Thin film rolls / Foil rolls / Coated rolls / Composite / multilayer / Very thin foils / Non standard foils e.g. BDF, BOPET, BOPP, BOPA

Precision through position-based measurement

FAQ

What is the optimum roll hardness and how does it contribute to the end product quality?

Roll hardness profile is an important property of parent reels and customer rolls. A correct winding process can be monitored throughout a roll hardness profile measurement and leads to a roll of a high quality

How does hardness correlate to the thickness profile?

Roll hardness is a roll feature that indicates the equality of the thickness profile and tension in a roll. In most cases, a relationship exists between the roll hardness and roll density. The higher the hardness value of...

How does the definition of a hardness roll profile help to avoid the runnability issues and increase product quality?

The control of roll hardness enables the users to early spot the defects that appear during the roll winding process. The winding is also one of the last processes during the paper and roll making. Hence the highest cost...
