Product Description
High Temperature Spreader Roll 12000mm Length 1500m/min Speed
Product Description
The High Temperature Resistance Spreader Roll with Black Color is engineered to spread thin plastic film and tissue wrinkle-free, ensuring perfect tension uniformity across the entire surface.
Spreader Roll Basis Information
- Available with rubber or silicon covering depending on material requirements
- Features helicoidal grooves from center to outside edges for optimal performance
- Maintains flat operation for consistent tension distribution
- Also known as Expander Rolls, Bowed Rolls, Curve bar Expanders, Banana Rolls, Camber Rolls, and Wrinkle removing Rolls
Spreader Roll Wrapping Angle
The wrapping angle is determined by the material being processed:
| Industry | Material | Recommended Angle |
|---|---|---|
| Paper industry | Forming fabrics | 25-20° |
| Wet felts | 30-60° | |
| Paper/board | 15-30° | |
| Film and Foil industry | Films PP and PA (1-6 Micron) | 60-90° |
| Films PP and PA (8-20 Micron) | 45-60° | |
| Films PP and PA (More than 20 Micron) | 45° | |
| Metalised films | 15-20° | |
| Textile industry | General | 45-60° |
| Extensible fabrics | 60-90° |
Expander Roll Working Principle
Unlike straight rollers, expander rollers feature a curved axis that creates tension across the web. As material approaches the roller, the edges tilt outward, stretching the material to prevent wrinkling while maintaining perpendicular transport across the roller surface.
Expander Roll Surface Options
- Hard chrome surface: Delivers high torque, excellent sealing, free rotation, and prevents oil leakage
- Rubber cover: Provides superior abrasion resistance and extended service life with unique end structures to prevent cover expansion/contraction
Expander Roll Function
The spreader roll's bow shape stretches running webs laterally to prevent wrinkling in various applications including paper machines, converting machines, and textile processing. Each roll is custom-designed for its specific installation and application requirements.
