What Are Bowed Rollers?

Bowed Rollers, also known as Bow Banana Rollers, are specially designed to eliminate wrinkles and creases that typically occur in wide web materials during processing. The key component of these rollers is the controlled bow (curvature), which helps stretch and spread the material without damaging it. The result is a smoother, tension-balanced surface across the web width.

These rollers are commonly used where web alignment and consistency are critical, making them indispensable in high-speed, high-precision industrial setups.

How Bowed Rollers Work in Industrial Applications

The design of a Bow Roll creates a spreading effect. As the web contacts the curved surface, it experiences tension redistribution, naturally removing wrinkles and preventing slack edges. The angle of the bow, the speed of the web, and the direction of rotation work together to ensure uniform web handling.

Common Use Cases:

  1. Slitting and Rewinding Machines
  2. Lamination Units
  3. Textile Processing Lines
  4. Plastic Film Production
  5. Flexible Packaging Machinery
  6. Paper & Nonwoven Lines
