Roll Covers

Since 1886, Xerium's Stowe Woodward division has been at the forefront of fabricating rubber, polyurethane, ceramic and composite roll covers for steel rolls used in the most demanding applications of papermaking and other industries. Papermakers rely on our roll cover technologies and roll refurbishment services to keep them in full production. Stowe Woodward uses data from paper manufacturers' monitoring systems to develop new materials that increase performance exponentially. No company has contributed more to the efficiency, reliability and productivity of today's high speed sheet and web industries.  

There is a Xerium roll cover solution engineered for your most demanding positions where product quality, machine efficiency and energy savings are prime objectives. More detailed descriptions are included below as well as product literature available for download.

This revolutionary, and now patented, roll venting technology continues to build on its well-documented success around the world...and is only available from Xerium! Customers are reporting savings in the hundreds-of-thousands of dollars per year!

Conventional roll covers with narrow grooves tend to “pinch” under load, and become increasingly ineffective over time. This is because the bottom portion of the groove’s void volume is partially blocked and unavailable for water removal. The problem increases with softer roll covers, and cover swelling can further choke these narrow grooves rendering the cover ineffective. 

EnerVent, however, is engineered with wider grooves and shallower depths creating greater groove wall stability and void volume. EnerVent covers remain effective under load, with softer covers, and throughout the cover life.

      • Reduces energy consumption
      • Improves production output
      • Improves sheet quality, uniformity
