Spreader Roller
Spreader rollers are specially designed expander rollers used to spread, smooth and prevent wrinkles in flexible materials like textiles, films, nonwovens, paper and foil. By using a curved or spiral structure, they gently stretch and guide materials to ensure flat, stable feeding during processing. With excellent wear resistance and smooth surface, they effectively improve product quality and production efficiency. Widely used in textile finishing, printing, laminating and packaging machinery, with customizable sizes and surface treatments available.
What you may want to know about Spreader Roller
As a professional industrial roller manufacturer, AstraRoll is a reliable spreader roller manufacturer and durable spreader rollers supplier, specializing in custom‑engineered web spreading rollers for film, paper, textile, non‑woven fabric, flexible packaging, lithium‑ion battery separators and printing industries. Spreader rollers are critical for eliminating wrinkles, web deviation and edge curling, evenly stretching materials and maintaining flat tension during high‑speed slitting, rewinding, laminating and coating processes. Our durable spreader rollers feature precision curved crowning, grooved designs and wear‑resistant coatings, delivering stable spreading performance for thin, delicate and wide‑web industrial materials.
We produce spreader rollers using high‑strength seamless steel, alloy steel and aluminum alloy cores. Common surface treatments include urethane coating, silicone coating, hard chrome plating, ceramic coating and precision spiral grooving. Roller crowning curve, spiral angle, groove pitch, coating hardness and surface texture are fully customized according to material width, tension and operating speed. Multi‑layer sealed bearings ensure low‑noise, long‑life operation under continuous high‑speed production.
Core Product Range
Curved Crown Urethane Spreader Rollers
Elastic PU‑coated crowned spreader rollers with excellent friction and anti‑slip performance, widely used for packaging film, paper and textile web wrinkle removal.

Custom‑angled spiral‑grooved spreader rollers with directional spreading force, ideal for wide‑web non‑woven fabrics, composite films and heavy‑duty converting lines.
Silicone‑Coated High‑Speed Spreader Rollers
Heat‑resistant, non‑stick silicone spreader rollers for high‑temperature coating, laminating and digital printing production lines.
Hard Chrome Plated Heavy‑Duty Spreader Rollers
Wear‑resistant mirror‑polished chrome spreader rollers for high‑abrasion film‑processing and metal‑foil conveying equipment.
Anti‑Static Precision Spreader Rollers
Anti‑static urethane/silicone spreader rollers for lithium‑battery separators, optical films and clean‑room electronic‑material processing machinery.
Key Features & Product Advantages
Effective Wrinkle Elimination & Web Stabilization
Precision‑designed crowning curve and spiral grooves generate outward‑directed tension, flattening wrinkles, folds and edge curling for smooth material transport.
High Wear Resistance & Long‑Term Durability
Premium urethane, silicone, chrome and ceramic coatings resist continuous friction and abrasion, extending service life in long‑hour high‑speed production.
Anti‑Slip & Tension‑Balanced Performance
Elastic coating surface increases friction coefficient, preventing web slipping while maintaining uniform tension distribution.
Material‑Friendly & Non‑Scratch Design
Soft elastic coatings avoid scratching thin films, separators and delicate fabrics, improving finished‑product yield rate.
Stable High‑Speed Rotation
Strict control over roundness, straightness and dynamic balance ensures low‑vibration performance for wide‑web and high‑speed converting equipment.
Full Customization Support
Customize crowning degree, spiral angle, coating hardness, surface texture and roller size to match different web materials, widths and processing speeds.
