Voith embeds wireless telemetry inside roll covers to eliminate static nip measurements

The historical blind spot in high-speed papermaking

For decades, the nip—the critical contact area between two rotating rolls—has been a frustrating blind spot for paper mill operators. We have historically relied on static nip impressions using pressure-sensitive paper during machine shutdowns. While these snapshots provide a baseline, they completely fail to capture the dynamic realities of a machine running at full production speed. Thermal expansion, dynamic crown inversion, and the hydrodynamic effects of pulp simply do not exist when the machine is idle. In 2026, operating a high-speed paper machine based on static data is no longer a viable strategy for mills facing tight margins and demanding quality standards.

NipDynamics brings real-time visibility to the roll cover

Addressing this fundamental industry challenge, Voith has officially rolled out NipDynamics, a sensor system engineered directly into the elastomeric roll covers. Rather than relying on external measurements or waiting for scheduled downtime, this technology embeds ultra-thin, heat-resistant sensors inside the roll itself. These sensors continuously transmit nip pressure profiles and rotational frequencies wirelessly to a customizable 3D visualization platform, all while the machine operates at full speed and under extreme temperatures.

Shifting from reactive troubleshooting to proactive control

The operational implications of this shift are substantial. Uneven nip pressure profiles directly compromise dewatering efficiency and the cross-machine moisture profile of the paper web. Left undetected, these inconsistencies lead to structural weaknesses, compromised product quality, and ultimately, web breaks. A single web break can cost a mill thousands of dollars in lost production time and wasted energy. By providing continuous telemetry, NipDynamics allows maintenance and production teams to detect roll cover misalignment or localized low line loads before they escalate into catastrophic failures.

According to Ralf Moser, Global Product Manager for Roll Covers at Voith Paper, the system gives papermakers continuous insight into nip conditions during active production. This capability allows mills to pinpoint previously hidden process deviations—such as a localized low line load correlating with a wet stripe in the paper profile—and address them immediately. The sensors are designed to integrate without compromising the profile performance, functionality, or the lifespan of the roll cover itself.

The broader impact on production efficiency

As we navigate the operational landscape of 2026, the push for higher runability and production efficiency is relentless. Technologies like NipDynamics represent a necessary evolution from reactive maintenance to condition-based monitoring. By dynamically optimizing nip loads, mills can maximize the operational lifespan of their equipment while ensuring consistent product quality. Voith's approach demonstrates a clear understanding that the future of papermaking relies on unlocking the data hidden within the most punishing environments of the machine.

The integration of robust telemetry directly into consumable components like roll covers marks a significant maturation in paper machine digitalization, proving that the most valuable data often comes from the hardest-to-reach places. How long will it take for embedded component telemetry to become the baseline standard rather than a premium upgrade across all major paper machine sections?
