Groove Press Roll

The Groove Press Roll is an advanced component in the press section of paper machines, designed to optimize water removal from the paper web. Featuring spiral or annular grooves on its rubber-coated or stainless-steel surface, the roll allows vertical downward drainage with minimal resistance and pressure loss. Its unique design supports higher linear nip pressure without crushing the paper, improving the dryness of the web entering the dryer.

This roll is widely used to replace vacuum presses in many applications, simplifying press section structures and reducing energy consumption. With proper groove specifications, the Groove Press Roll can achieve dryness levels of up to 58–60%, offering a reliable alternative for enhanced papermaking efficiency.

• Enhanced Dehydration: Grooved surface facilitates vertical water flow, reducing resistance and maximizing drainage efficiency.

• Higher Dryness Levels: Improves paper web dryness to 58–60% before the dryer, boosting productivity.

• Energy Efficiency: Replaces vacuum presses in many setups, reducing power consumption and simplifying machinery design.

• Durable Construction: Available in rubber-coated or stainless-steel configurations for long-lasting performance.

• Flexible Design: Spiral or annular grooves can be customized to match specific production needs.

• Wide Applications: Used in press sections of various paper machines globally, contributing to high-quality paper production.
