Bowed spreader rolls are used in paper, paperboard and pulp machines, as well as in textile and plastic machines for spreading the pulp and material onto the web. We have manufactured more than 1,000 spreader rolls and supplied them worldwide to more than 30 countries.
Our roll production has been certified in accordance with the ISO 9001 quality assurance system. We only use high-quality raw materials and components from approved suppliers.
The spreader rolls are manufactured from steel and coated with rubber. The finishes are selected based on the use and the customer's wishes. For great web velocities, the surface of the roll may be grooved to enhance the spreader roll's performance. In addition, our spreader rolls can be fitted with vibration and temperature sensors. The measurements extend the life span of the roll and help prevent issues with maintenance.

TEVO produces high-quality rubber and rubber-metal products for demanding industrial applications including flexible rubber couplings for spreader rolls. In them TEVO has its own patented design. Thanks to their characteristics the steel-reinforced flexible TEVO® rubber couplings make spreader roll’s shell tight and uniform.
In connection with overhauls TEVO can fabricate fully identical rubber couplings for your existing bowed rolls. Couplings are made by using a specially tailored mold in which the rubber material is put and then processed in a logic-controlled press. TEVO has individual molds for most coupling types of any roll make and design being on the market.
