Roll Hardness Profilers for Paper, Board and Plastic

Tapio RQP Live Roll Quality Profilers help you detect hidden roll defects before they cause costly problems. Our solution provides deeper insights by analyzing multiple layers of the roll, ensuring consistent quality from edge to edge – you can be sure that every roll meets the highest standards.

Smarter Roll Hardness Testing

The hardness profile of a roll is a great overall measure of roll quality. Tapio’s handheld RQP Live devices quickly and accurately measure roll hardness profiles, detecting inconsistencies that could impact production quality. With Tapio RQP Live you will:

Quickly obtain a high-resolution hardness profile.
Identify loose edges, hardness variations, and tension inconsistencies.
Prevent defects from reaching customers.
Easily take equipment into use with the interactive user experience of the device. A first-time user can successfully measure rolls with Tapio RQP Live.

Immediately after measurement, Tapio RQP Live will show the hardness profile and statistical KPI’s on the display. Statistics exceeding specified limits will be flagged in red to enable the operator to easily accept or reject measured rolls.

Suitable Applications for Tapio RQP Live

Paper rolls
Plastic rolls
Customer rolls
Parent reels
Machine rolls
Roll cores
Roll ends can also be measured
Alert limits – Pass/fail notifications to instantly flag bad rolls.
Small and large rolls: 10 cm to 5 m diameter
Short and long rolls: 10 cm to 20 m

Typical application grades

Widely used in consumer packaging board grades
Sack, Kraftliner and Fluting are good examples of applications
Various plastic film applications. Flexible packaging, BOPP etc.
Release paper, customers have also opted for automatic online profiler
Used widely for S/C grades
LWC is one of the most common amongst the RQP users to help with slitting process optimization
Newsprint. Runnability of the printing machine requires high quality rolls. The tightness near the core is especially important
Also used as a QCS performance follow up tool to verify cross direction profiles

How does it work?

The measurement is based on measuring the deceleration of an impact hammer hitting the sample over 30 times per second while simultaneously measuring the location of the profiler.

The device has a barcode scanner which can be used to automatically create or activate a roll folder. During measurement, the current hardness, location and speed are shown on the display.

After measurement, the device displays the hardness profile and statistical KPI values of the measured roll, allowing for a quick and efficient judgment of the roll quality with a convenient alert limits feature.

The device is provided with Tapio RollView, an easy-to-use software for further transfer and processing of the measured data on a computer system. The complimentary software is available for download and install at https://github.com/Tapio-Measurement-Technologies/tapio-rollview

A QR code to quickly set device settings (such as alert limits) can be created with the Tapio RQP Live Configurator Tool.
