Valmet Oyj's trade press release May 20, 2022 at 11:00 a.m. EEST

Tissue machines represent the most challenging environment for press rolls due to high machine speeds and extreme Yankee cylinder temperatures - placing high demands on the roll covers as well.

Compared to other cover products, Valmet Press Roll Cover PL is available with wider hardness range together with improved mechanical properties, from 5P&J to 50P&J.

The adaptive roll cover structure of Valmet Press Roll Cover PL helps to achieve more uniform nip profiles and bulk savings.

" To limit the energy needed for drying the tissue sheet, we usually concentrate on improving the post-press dryness. It reduces the energy demand on the Yankee dryer, which in turn removes bottlenecks in the dryer's performance and operating costs", Ulla Kanerva explains.

Valmet Press Roll Cover PL offers t he possibility for high open grooved areas and large void volumes, assuring maximal nip dewatering and consistent tissue quality. By selecting optimal roll covers and surface topography with a matching press felt, tissue makers can further improve dewatering.

"To summarize, choosing Valmet Press Roll Cover PL leads to energy savings, better runnability and improved time efficiency in tissue production. On the other hand, the wear-resistant polyurethane material also extends the roll cover change intervals, leading to further cost savings", Kanerva continues.
