Join us to explore how Valmet’s groundbreaking Sleeve Roll Technology is transforming the forming process by reducing energy consumption, optimizing dewatering, and helping paper and board makers achieve sustainability goals.
The forming section is the biggest user of vacuum energy on paper and board machine lines. Until now, forming section drainage has relied on gravitation and dragging vacuum elements set along the forming fabric’s journey. A new innovative breakthrough has been made in board and paper machine technology to transform this forming process.
This innovation, Sleeve roll technology, redefines dewatering by harnessing the power of compression already in the forming section, reducing the need for energy-intensive vacuum methods that conventional forming technologies rely on. As Sleeve roll technology does not require vacuum energy, it saves energy in both the vacuum system and drives of the forming section, helping paper/board makers to reduce CO2 footprint.
Sleeve roll technology can also help you optimize dewatering processes, minimize downtime, and maximize throughput, all which contribute to improved performance and increased production.

Petteri Halme
Sr. Technology Manager, Board & Paper Machines Valmet, North America, Valmet
Petteri began his career in the Pulp & Paper Industry and with Valmet-Karhula in 1994 as a development engineer working with mechanical designs of various paper machine sections & rolls. He got involved with shoe pressing which later led him to experiment papermaking with Valmet’s pilot machines as R&D Manager, Press Section in Jyvaskyla, Finland. In this capacity, he helped with launching, commissioning & optimizing new press section configurations in close cooperation with Valmet project teams and customers. Later he was in charge of Valmets press section project engineering as Engineering Manager, Press Sections in Jyvaskyla, Finland. He currently holds a position of Technology Manager in Valmet’s North American Paper Machine Technology Group supporting Valmet’s North American customers and various Valmet North American teams.
Petteri holds a Master’s Degree in Machine Design from the University of Technology in Lappeenranta, Finland. He’s based in Norcross, GA.
Tuuli Silomaa
Development Engineer, Wet End R&D, Valmet
Ms. Silomaa, a promising young talent, earned her Master of Science degree in Mechanical Engineering from the University of Oulu in 2017.During her studies, 2012 – 2015, Ms. Silomaa worked as a process operator at Stora Enso Sheeting factory in Oulu. After completing her studies and finishing her master’s thesis for Valmet, Ms. Silomaa continued to work for Valmet as a Development Engineer in Rolls R&D for 4 years. During this time, she was working in several demanding product development projects of deflection compensated rolls for the paper and board machine industry.
Leveraging the knowledge gained in the rolls R&D engineering position, Ms. Silomaa made a seamless transition to Wet End R&D as a Development Engineer in 2021. Currently, she works there as a Product Responsible Development Engineer for the Sleeve roll technology.
