Roll covers tailored for your needs
Improved dewatering with press roll covers
Valmet provides a comprehensive range of roll cover solutions featuring advanced dewatering technology, designed for various tissue press configurations and roll positions. Valmet Press Roll Cover PH and Valmet Press Roll Cover PL, for press and suction rolls bring energy savings in tissue production with efficient dewatering. The exceptionally wide hardness range design of Press Roll Cover PL enables an adaptive roll cover structure and thus better final product profile and bulk savings.
Our selection ranges from economical rubber covers for less demanding applications to state-of-the-art polyurethane roll covers that ensure improved press nip loading and constant operating parameters in demanding pressing conditions.
Bioneer roll cover family – Sustainable innovation for tissue rolls
Valmet’s Bioneer roll covers set a new standard in sustainability by using recycled, renewable or bio-based materials. These covers reduce reliance on fossil resources and come with verified climate impact through life cycle assessments.
Polyurethane covers for tissue making Press Roll Cover PL Bioneer for press rolls and Valmet Press Roll Cover PL-V Bioneer for suction rolls provide durability, wear resistance and dewatering performance with reduced climate impact.
Environmental benefits of Valmet Press Roll Cover PL Bioneer
- Achieve up to 12,2% lower CO2 emissions (cradle-to-gate) compared to
a standard product - REDcert2 –certified renewable (bio-based) and/or recycled material through a mass balance approach*
- First press roll covers with verified climate impact through third-party assured life cycle assessment (LCA)
*Mass balancing is a method for mixing fossil and renewable/recycled/bio-based raw materials in production, offering a means to reduce the overall share of fossil materials in products.
Example: Total cradle-to-gate emissions for Press Roll Cover PL Bioneer, kgCO2e/1 m2 of product, calculated with 5 P&J hardness
Better dryness and runnability with Doctor Blade Dual
The press section also has a major impact on sheet surface properties such as tissue bulkiness and thickness. Achieving the desired tissue quality depends on water removal efficiency and the roll covers' uniform properties. In addition to press roll covers, Valmet offers solutions for better dewatering and sheet dry content with Doctor Blade Dual, a doctor blade with two patented functions that solves roll doctoring problems in challenging press section positions.
iRoll Press improves nip profiles and runnability
Runnability and quality defects due to press nip profile variations cause problems with sheet quality and water removal, as well as increased energy consumption. Valmet iRoll Press creates new options for improving press function and offers a solution to these problems. In addition to improved press nip loading, iRoll Press offers an extended roll cover lifetime and smooth runnability.
