ROLLS

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.

Made to work

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.

Finishes for steel-sheathed rollers

• Hard chromium
• Chromium Teflon
• Wolfram carbide
• Wolfram carbide & Teflon

Finishes for rubber-sheathed rollers

• Nitrile-rubber NBR, black
• Hydrated nitrile-rubber HNBR, red

In addition, rubber-sheathed rolls can be fitted with seamless, etched Teflon socks to ease the detachment of the sheath.
