Custom NBR Rubber Banana Spreader Roller

Custom NBR Rubber Banana Spreader Roller——Built for Stable Web Spreading

The AstraRoll Custom NBR Rubber Banana Spreader Roller is designed for continuous web-processing lines where wrinkles, creases, slack edges, or uneven web spreading can affect production quality. Its bowed roller structure creates a controlled lateral spreading effect as the web passes across the rubber-covered surface, helping flatten the material and maintain a more stable web path.

The NBR rubber covering provides a flexible contact surface with good grip and wear resistance, making the roller suitable for applications where reliable web contact and wrinkle control are required. NBR-covered Banana Rollers are commonly used in printing, textile, paper, film, flexible packaging, coating, laminating, slitting, and rewinding equipment.

NBR Rubber Surface
NBR rubber provides a resilient working surface for continuous contact with flexible web materials. The rubber compound and hardness can be selected according to the material being processed, operating conditions, and required spreading effect.

Banana-Type Spreading Structure
The curved or bowed configuration guides the web outward from the center toward both sides as it travels over the roller. This helps reduce wrinkles and folds while improving web flatness and lateral distribution.

Suitable for Continuous Web Processing
The roller can be integrated into different stages of a production line, including unwinding, coating, printing, laminating, slitting, and rewinding. It is particularly useful where consistent web spreading and wrinkle control are required before downstream processing.

Application-Specific Customization
AstraRoll manufactures the roller according to the actual machine configuration and web-processing requirements. Key specifications such as roller diameter, working width, bow amount, NBR hardness, rubber covering thickness, shaft dimensions, bearing arrangement, and mounting structure can be customized.
