Sheets Unlimited Controls Corrugated Board Warp With Valmet Valmet will supply a Valmet IQ Quality Control System for corrugator to Sheets Unlimited, one of the largest in- dependent corrugated box manufacturers in the Pacific Northwest, located in Renton, Washington. The system will address key quality challenges, most notably mois- ture imbalance which is the root cause of warp, to im- prove board quality, production efficiency, and overall converting performance. Sourcing Stock For independent sheet feeders like Sheets Unlimited who source roll stock from multiple mills, it is critical to en- sure consistent quality and efficient production. Variations in paper grades, moisture levels, and fiber characteristics create unpredictable warp behavior that standard corru- gator controls cannot fully manage, affecting converting performance, customer satisfaction, and material waste. “We had the opportunity to see Valmet’s warp con- trol solution in operation at another manufacturer in Europe,” said Krist Leland, Director of Manufacturing, Sheets Unlimited. “What stands out is its ability to ad- dress the root cause of warp: moisture imbalance. Based on the strong feedback from users and our own evaluation, we are confident in the value it brings to our operations. With this solution, we are well positioned to reduce variability, improve converting performance, and deliver products of even higher quality to both our inter- nal and external customers.” “With Valmet IQ, the customer will benefit from im- proved process stability, more uniform product quality, and reduced operator workload,” said David Maddux, Board Converting Automation Sales Manager, North America, Automation Solutions, Valmet. “The system’s precise mois- ture and warp measurements, combined with advanced automation, help minimize material waste and improve re- source efficiency, while supporting sustainability targets. This project demonstrates how intelligent automation can enable more streamlined operations and enhanced over- all performance.” The delivery includes combined paper temperature, moisture balance, total moisture and warp control, utiliz- ing an interface to the existing state-of-the-art corrugator heating elements. It also incorporates Valmet’s proven moisture measurement technologies and automatic mois- turizing solution. The order was included in Valmet’s orders received in the second quarter of 2026. The value of the order will not be disclosed. The delivery is scheduled for the fourth quarter of 2026, with commissioning planned for January 2027. The delivery consists of Valmet IQ Warp Measurement, Valmet IQ Moisturizer, Valmet IQ Multipoint Moisture, and Microwave moisture measurement, integrated with auto- matic closed-loop controls.
