Roll Covers

    Roll cover technology is a key factor in improving sheet release, reducing draw, improving dewatering performance, ensuring consistent coating and sizing, and excellent calendering results. The various applications on the paper machine require a variety of roll cover designs and coating materials.

    The materials used range from ceramic coatings to very soft elastomeric covers.

    The surface profiles range from plain polished to high open surfaces, as well as complex cross-machine direction crown designs. Contact us - together we find the perfect roll cover for you!

      Find Your Perfect Roll Cover

        Forming

        Roll covers in the forming section need to guide and tension the fabric.

        Some of the rolls have to transmit the drive force to the fabric, while other rolls perform dewatering functions. The roll covers need to be doctorable and wear resistant, have good traction properties, and perform with no sheet marking. Voith offers roll covers in rubber, polyurethane, composite and resin, as well as hard metal coatings for the various applications in the forming section.

        Roll types in the forming section:

        • Breast Roll
        • Couch Roll
        • Forming Roll
        • Lumpbreaker
        • Table Roller
        • Wire Drive Roll
        • Wire Suction Roll
        • Wire Guide Roll

        Press

        Roll covers in the press section must remove the remaining water via a system of nips pressing against each other, aided by press fabrics that support the sheet and absorb the pressed water.

        High surface stability, no marking, sufficient operating volume, high wear resistance and impact resistance and doctorability are some of the necessary features a roll cover needs in the press section. Depending on the specific roll application, we offer polyurethane, rubber and thermal coatings.

        Roll types in the press section:

        • Centre Press Roll
        • Centre Suction Press Roll
        • Felt Guide Roll
        • Glazing Cylinder Pressure Roll
        • LNP Soft Roll
        • Paper Guide Roll
        • Pick-up Suction Press Roll
        • Press Roll Hard
        • Press Roll Hard Vented
        • Press Roll Soft
        • Shoe Press Counter-Roll
        • Smoothing Press Roll
        • Suction Press Roll
        • Spreader Roll

        Dryer

        In this paper machine section, the paper web is heated with steam to reach the necessary dryness value.

        The harsh environment cylinders and guide rolls are prone to contaminations and corrosions. They need special thermal and metal coatings for corrosion protection, as well as wear and contamination resistance. We offer specially developed coatings for all applications.

        Roll types in the dryer section:

        • Dryer Cylinder
        • Dryer Wire Guide Roll
        • Dryer Paper Guide Roll
        • Spreader Roll

        Coating & Sizing

        For demanding print results that are brilliant in detail and require very smooth, closed surfaces, Voith Paper offers a wide range of roll covers for sizing and coating applications.

        Using our sizing and coating roll cover knowledge combined with our expertise as a paper machine supplier, we are able to ensure the roll cover selected meets your expectations. Depending on the specific demands, we offer polyurethane and rubber roll covers.

        Roll types in the coating and sizing section:

        • Coater Applicator Roll
        • Coater Backing Roll

        • Film Press Applicator Roll
        • Spreader Roll
        • Size Press Hard
        • Size Press Soft

        Calender

        Depending on the purpose for which a paper is used, its surface must have certain properties – especially smoothness and gloss.

        These properties are imparted to the paper by calenders, which are equipped with up to 15 rolls. Our calender roll cover product line offers an extensive cover choice for all application requirements. Optimized fiber-reinforced composite covers and world-class thermal coating covers provide optimum paper gloss, smoothness, and bulk while maintaining cover profile and surface consistency.

        Roll types in the calender:

        • Soft Nip Calender Elastic Roll
        • Soft Nip Calender Hard Coating
        • Super Calender Elastic Roll
        • Super Calender Hard Roll
        • Spreader Roll

        Reeling & Winding

        During reeling the paper web is wound up on reel spools.

        We offer rubber or polyurethane covers on reel spools, providing a perfectly closed nip when starting the winding process on the spool and running smoother with reduced noise. During winding, the paper is cut into narrow rolls. Our polyurethane covers have superior cut resistance and remain in better condition for more consistent winding. We also offer thermal coatings that can be either applied on site or in one of our locations equipped with thermal spraying.

        Roll types in the reeling and winding section:

        • Reel Drum Hard
        • Reel Drum Soft
        • Reel Spool
        • Rider Roll
        • Squeeze Roll
        • Winder Drum

        Special

        We offer excellent roll covers which meet the specific requirements also for special applications.

        Marking and splicing rolls are used for applications in which the roll covers must meet the special requirements – such as very high wear resistance or a soft surface. For these special applications, we offer excellent roll covers.

        Roll types for special applications:

        • Marking Roll
        • Splicing Roll

        Tissue

        Roll covers in tissue machines need to offer excellent wear and thermal resistance with high hardness stability to provide excellent operational safety.

        Coatings for Yankee cylinders must withstand rough conditions and therefore offer high wear and corrosion resistance. Depending on the specific tissue machine requirements, we offer different covers and coatings.

        Roll types in tissue machines:

        • Tissue Pressure and Suction Pressure Roll
        • Yankee Cylinder
        • MG Cylinder

          MatchPress and MatchFlow

          With MatchPress and MatchFlow, we offer press and suction press roll covers that are specially designed for small and medium-size paper machines. The excellent dewatering capacity is a result of the customized surface designs. Our MatchPress and MatchFlow roll covers running reliably and deliver consistent paper quality for our customers.

          NanoGloss

          NanoGloss offers a smart combination of highest gloss levels and mechanical stability and thus produces paper with a wonderful glow and smoothness. Good calendering is a challenging task as it consists of two stages impacting each other. At first one paper side faces a series of thermo rolls to create perfect smoothness and gloss. In a next step the paper faces composite rolls. Any surface roughness and topographical structure of their covers will leave an imprint in the paper just like a fingerprint. Only NanoGloss with its smooth and even surface maintains all the beautiful calendering effects over the entire lifetime.

          InForce

          InForce is a polyurethane roll cover for the press section that offers optimum strength, abrasion resistance and groove stability. The InForce roll cover ensures consistent dewatering performance contributing to stable dry content and potential energy savings. InForce is a further development of the proven G2000 cover and has outstanding groove stability even under extreme conditions. For applications with a maximum void volume, further sophisticated surface designs are available in blind-drilled or blind-drilled-grooved versions. InForce is an extremely hard polyurethane roll cover, perfect for replacing stainless steel roll covers with the additional benefit of extending the service life of the clothing.

          TerraDry HC+ Express and TerraDry MG Express

          TerraDry are our excellent thermal coatings for MG and Yankee cylinders.
          • TerraDry MG Express is a high performance coating for MG cylinders specially designed to protect against excessive corrosion and wear, ensuring optimum conditions for glaze and gloss of the paper.
          • TerraDry HC+ Express is a high performance coating for Yankee cylinders specially designed for protection against excessive corrosion and wear.
