Product Description

Curved Bow Roll/Banana Roll/Spreader Roll

Curved roller is a device composed of a fixed curved shaft and a rotatable roller surface, which eliminates wrinkles by stretching the web material. It is mainly used in material processing equipment such as paper, film, and textiles, and can replace ordinary guide rollers in special installation positions. Its core function is to adjust the tension distribution of materials, prevent interlacing during the cutting process, and adapt to different materials to adjust the package angle (10 ° -100 °) and flattening direction.

Classification of Bow Roll

According to the material and purpose, it can be divided into types such as adhesive surface, metal surface, adjustable crown, and customized shaped rollers. Adhesive surface rollers are commonly used in rolling and coating processes, while metal surface rollers are mostly used in rewinding machines and other equipment. The surface can be treated with tungsten carbide or hard chromium.

Rubber Coated Bow Roll

Rubber coated bow roll plays a key role in the processing of materials such as paper and board, fur, film, textiles, etc., especially in the processes of rolling, calendering, coating, and lamination. The adhesive surface material can be customized according to user needs and application scenarios, such as wear resistance, high temperature resistance, and special treatments such as surface slotting or installation of PTFE sleeves, to meet different processing requirements.

Metal Curved Bow Roll

Metal surface curved rollers are widely used in various processes, such as rewinding machines, calendering machines, coating machines, etc., especially in the winding and felt press sections. These rollers are often used to eliminate wrinkles in the web material. Its metal surface has undergone special treatment, such as tungsten carbide, Teflon chromium, hard chromium, etc., to meet different usage needs. In addition, special processes such as surface grooving can also enhance its performance.
