A banana roller, also known as Baloney Roll, or Spreader Roller, is a crucial component in a wide array of industrial processes, especially those related to the processing of foil materials, including printing, converting, extrusion, and lamination. Banana rollers consist of multiple rolling elements mounted on a curved shaft, serving two primary purposes: stretching the foil and eliminating folds and lines or altering the foil’s direction. Often, the banana roller is covered with a rubber sleeve, offering both grip and protection to the foil.
The main purpose of a banana roller is its ability to manage controlled stretching or direction change of the foil. The effectiveness of a banana roller is determined by the degree of stretching and curvature relative to the foil. The banana roller achieves this by guiding the foil over its curved shaft, stretching the material and removing folds and lines. The result is a smooth, folds and line-free surface, ensuring high product quality and meeting industrial standards.
We offer a wide selection of banana rollers, customized for various industrial needs and applications. Our banana rollers come in a range of lengths and diameters, often equipped with an EPDM rubber sleeve for enhanced durability and performance. We offer two primary types of banana rollers: Type 1 with a fixed curvature, whose angle can be adjusted via a handwheel or tool, and Type 2 with fully adjustable curvature and angle for ultimate adaptability. Our banana rollers can be mounted with either bearing housings or steel bearings on machine frames, ensuring stable and efficient operation. Each banana roller has a rotating body, guaranteeing a seamless and efficient performance.
We supply banana rollers to both machine manufacturers (OEMs) and production companies (end-users). We strive to provide versatile and reliable high-quality banana rollers designed to ensure your foil processing applications run smoothly and efficiently.
