Metallic Bow Rolls—also known as Metallic Banana Rolls or Wrinkle Removing Rolls—are precision-engineered rollers used to eliminate wrinkles, separate layers, and evenly spread web materials during processing. These rolls feature a metallic construction (usually Mild Steel or Stainless Steel) and a curved or "bowed" shaft that creates a lateral stretching force on the web, effectively removing creases and improving material alignment.

Key Features:

• Material Construction: Made from high-grade Mild Steel (MS), Stainless Steel (SS), or Aluminum

• Bowed Shaft: Precisely engineered curvature (1° to 3° typical) for optimal spreading effect

• Surface Finish: Chrome-plated, polished, or anodized metallic surface for smooth web handling

• Durability: Rigid and corrosion-resistant for continuous industrial use

• Vibration-Free Operation: Dynamically balanced for smooth performance even at high speeds

Technical Specifications:

• Roll Diameter: 75 mm to 200 mm (standard/custom)

• Face Length: 300 mm to 6000 mm

• Bow Angle: Adjustable to suit web type and application

• Surface Options: Bare metal, chrome-plated, or coated with anti-stick finishes

• Mounting: Foot, flange, or pedestal mounted

Applications:

• Textile and nonwoven fabric processing

• Plastic film and flexible packaging lines

• Paper and pulp converting machinery

• Lamination, coating, and slitting machines

• Rubber sheet and tire cord production

Advantages:

 

• Efficient wrinkle removal across a wide range of materials

• High strength and long service life with metallic body

• Suitable for high-speed, high-tension applications

• Customizable design for different web widths and machine layouts

• Maintenance-free operation with no internal mechanisms

We are leading manufacturers of Metallic Segment Type Bow Roll.

Types:

• Rubber Sleeve Covered. (High-Quality Synthetic Nitride Sleeve).
• Metal Expander with hard chrome plated surface for high-speed application
• Vary Bow Expander Roller
• Teflon Sleeve Expander Roller for non-sticking application

Working of Bow Roll:

• Single Acting Bow Roll
• Double Acting Bow Roll

Performance depends upon the following points:

• Wrap angle
• Lead-in & Lead-out distance
• Position of bow (Adjustable)

Banana Bow Rolls—also known as Bowed Rolls or Spreader Rolls—are specially designed rolls used to eliminate wrinkles, remove slack edges, separate web materials, and spread web evenly during processing. Their unique curved or "banana-shaped" structure provides a natural spreading effect as the web travels over the roll, making them essential in high-speed and precision applications across various industries.

Key Features:

• Construction: Available in rubber-covered, PU-covered, or metal segment types

• Bow Adjustment: Adjustable bow angle to suit different materials and machine configurations

• Material Compatibility: Suitable for films, foils, paper, textiles, non-wovens, and laminates

• Smooth Operation: Vibration-free and noise-free performance at high speeds

• Durability: Built to withstand continuous operation in harsh environments

Technical Specifications:

• Roll Diameter: 75 mm to 150 mm (or customized)

• Face Length: 300 mm to 6000 mm (or customized)

• Bow Angle: 1° to 4°, adjustable

• Covering Options: Natural rubber, EPDM, silicone, PU, or as specified

• Mounting Style: Pedestal, flange, or foot-mounted bearings

A Metal Expander Roller is an industrial tool designed to manage web materials—such as plastic film, paper, textiles, or foil—during high-speed processing. Its main function is to eliminate wrinkles, control slack edges, and ensure smooth, uniform tension across the material.

Key Features

• Bowed Shaft Design: Distributes tension evenly and removes wrinkles from the web.
• Hard Chrome Plated Surface: Provides durability and supports high-speed operations.
• Sealed Ball Bearings: Enable smooth rotation and reduce maintenance needs.
• Abrasion-Resistant Sleeve: Enhances longevity and performance under continuous use.
• Mounting Options: Available in wall-mounted or foot-mounted configurations.

Applications

• Printing and Packaging: Used in flexo, gravure, offset, and lamination machines.
• Textile Industry: Common in stenter, dyeing, and rotary screen printing machines.
• Plastic and Paper Processing: Found in slitter rewinders, calendars, and pipe plants.

Advantages

• Removes wrinkles and baggy centers
• Separates slit webs on winders
• Controls lateral tension across the web
• Improves material handling efficiency

These rollers are often customized in terms of diameter, length, and surface finish to suit specific industrial requirements. If you’re working with a particular machine or material, I can help narrow down the best configuration.
