Scroll Spreader Rolls are specialized web-handling rollers designed to remove wrinkles, spread materials uniformly, and maintain edge alignment in continuous web processes. These rolls feature a precisely machined helical or spiral groove pattern on their surface that gently stretches the web toward the edges as it passes over, making them ideal for thin, elastic, or sensitive materials.

Key Features:

• Spiral Groove Design: Machined in a helical pattern to apply outward tension on the web

• Roll Material: High-quality Mild Steel, Stainless Steel, or Aluminum

• Surface Finish: Hard chrome plated, anodized, or polished to prevent marking or slippage

• Non-Contact Spreading: Provides wrinkle-free operation without physically gripping or distorting the web

• Maintenance-Free: No internal mechanisms; easy to clean and operate

Technical Specifications:

• Diameter Range: 50 mm to 150 mm

• Face Length: 300 mm to 6000 mm (customizable)

• Groove Pitch & Depth: Engineered to match material type and line speed

• Material Options: MS (chrome plated), SS (for corrosion resistance), or Aluminum (lightweight)

• Mounting: Available with foot, flange, or customized end fittings

• Speed Compatibility: Suitable for low to high-speed web lines

Applications:

• Plastic film and foil converting

• Paper, board, and tissue processing

• Textile, nonwoven, and fabric spreading

• Printing, laminating, and coating machines

• Pouch making and slitting lines

Welcome to Bel Mark Industries Established in 1995 for manufacturing and exporting of Banana Bow Roller, Metallic Bow Roll, Rubber Bowed Roll, Slat Expander Rolls, Safety Chucks, Industrial Rollers, Scroll Rolls, Tyre Cord Centralizer, Air Shaft, Rubber Roller, etc.

Polyband Expander Rollers are specialized web-spreading rollers designed to eliminate wrinkles, separate layers, and maintain even web tension across the width of various materials. These rollers feature multiple high-strength polyurethane bands (polybands) stretched over a lightweight aluminum or steel shell, providing consistent, gentle spreading without damaging delicate substrates.

Key Features:

• Construction: Central shell (typically aluminum or MS) with multiple stretchable polybands attached to end discs

• Material: Shell in Aluminum, Mild Steel, or Stainless Steel; Bands in premium-grade polyurethane

• Smooth Web Handling: Ideal for thin, sensitive, or easily wrinkled materials

• Lightweight Design: Reduces load on machine bearings and supports higher speeds

• Vibration-Free Operation: Dynamically balanced for smooth, stable performance

Technical Specifications:

• Roll Diameter: 100 mm to 160 mm (standard), customizable

• Face Length: 300 mm to 4000 mm or as per requirement

• Number of Polybands: Typically 6 to 20, depending on roll width

• Polyband Properties: Anti-static, heat-resistant, and chemical-resistant options available

• Mounting: Foot, flange, or pedestal mounted shafts

Applications:

• Flexible packaging film production

• Paper and foil converting

• Textile and nonwoven processing

• Plastic sheet extrusion and lamination

• Slitting and rewinding machinery

Advantages:

• Uniform wrinkle removal without applying excessive tension

• Suitable for delicate webs where rubber or slat expanders may cause damage

• Lightweight and maintenance-free design

• Effective over a wide web width

• Easy installation and no adjustment of bow angle required
