Technidyne ACA RoQ Roll Hardness Profiler

The ACA RoQRoll Hardness Profiler measures roll hardness profiles – used to troubleshoot and optimize roll making, converting, and finished processes. 


Brought to you by Technidyne, our specialist optical, surface, and physical property testing brand, this roll hardness profiler blocks baggy rolls and eradicates runnability issues.  

Roll hardness profiler basics 

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. 

If your rolls of paper, paperboard, cardboard, corrugated, films or non-wovens are wound too soft, or too tight, then you’ll encounter problems. Rolls should be wound to support their own weight and sustain some impact and compressive loads during shipping and handling. 

The benefits of roll hardness profile testing

When you examine your rolls properly using our accurate and effective ACA RoQ™ Roll Hardness Profiler you will: 

Save money and protect your reputation: fewer roll quality complaints equals less product wastage and happier customers!  

Swiftly understand roll problems: our roll hardness profiler will identify all sorts of problem areas from rope marks and bagginess through to soft edges and wrinkles.  

Enjoy greater accuracy: Our roll hardness profiler gives you a level of granular detail that you won’t find with many other similar products on the market. 

​Caliper variations are often too small to be picked up by online scanners or test labs. The good news is, you can easily identify problematic rolls using our sophisticated roll hardness profiler inspection machines. 

A troubleshooting roll hardness profiler

The ACA RoQ roll hardness profiler accurately measures hardness profiles, which can be used to troubleshoot and optimize roll making, converting and finishing processes.
