Exploring the Technidyne ACA RoQ Roll Hardness Analyzers: Features, Applications & Demonstration

Overview

This video features two Technidyne roll hardness solutions: the ACA RoQ Inline Roll Hardness Analyzer and the handheld ACA RoQ Roll Hardness Profiler. Both measure the hardness profile of wound rolls so paper, paperboard, corrugated, film and non-woven producers can spot soft edges, bagginess and inconsistent winding before they cause runnability problems or customer complaints. The Inline unit is fully automated and installs directly on the production line, measuring every roll after winding and before packaging with no operator needed. The handheld Profiler is a mobile device for spot-checks and troubleshooting. In this video, you’ll see how both work and where each fits in a roll quality workflow.

Key features of the ACA RoQ range

ACA RoQ Inline Roll Hardness Analyzer

• Fully automated, inline measurement of every roll after winding and before packaging
• Non-destructive testing with precision sensors, with no operator or real-time supervision required
• Real-time data collection with automatic anomaly detection for continuous roll quality monitoring
• Automated data handling and communication with mill systems, compatible with digital production setups
• Supports complete roll documentation and traceability
• Helps with reclaim handling, roll quality classification and cross-direction (CD) profile control

ACA RoQ Roll Hardness Profiler (handheld)

• Mobile, handheld roll hardness profiler for spot-checks and troubleshooting
• Embedded 4.3 inch touch screen for instant on-screen profile data
• WiFi connectivity and USB for flexible data transfer and storage
• Built-in barcode reader (camera) for fast roll identification
• Suitable for paper, paperboard, cardboard, corrugated, films and non-wovens
• Identifies rope marks, bagginess, soft edges and wrinkles down to fine caliper variations

Understanding roll hardness profiling

Roll hardness profiling checks how firmly a roll is wound across its width and from core to outside. A good roll is wound with uniform or gradually diminishing hardness from the core outward, so it can support its own weight and withstand impact and compressive loads through shipping and handling. Rolls wound too soft or too tight lead to problems such as soft edges, bagginess, rope marks and wrinkles – and often to runnability issues or customer complaints further down the line.

Measuring the hardness profile lets producers define a good or bad roll objectively rather than by feel. Caliper variations across the web are often too small for online scanners or lab tests to catch, but they show up in the roll hardness profile. The two ACA RoQ units approach this in different ways: the Inline Analyzer builds the check into the line and measures every roll automatically, which removes operator variation and supports full traceability, while the handheld Profiler gives quality and R&D teams a portable way to investigate specific rolls and troubleshoot winding, converting and finishing processes.

Typical applications

The ACA RoQ analyzers are used across roll-based production and conversion, including:

• Paper and paperboard roll production
• Corrugated paper and cardboard manufacturing
• Film and non-woven roll converting
• Hardness testing and materials testing for wound roll quality control
