Angle rollers are specialized machines used in metalworking to bend and shape metal sheets and rods into specific angles. They typically consist of three rollers arranged in a triangular configuration, allowing users to create precise curves and bends. These machines are essential in industries such as construction, automotive, and manufacturing, where accurate metal shaping is crucial. The process of using an angle roller involves feeding the metal through the rollers, which apply pressure to achieve the desired angle. Operators can adjust the spacing and position of the rollers to accommodate different materials and thicknesses, making angle rollers versatile tools for various projects.
