A roll straightener machine is a type of industrial equipment used primarily to remove bends, coils, or curves from metal strips, bars, and wires. The machine accomplishes this task through a series of rollers arranged in a specific configuration. As the metal strip passes through these rollers, controlled pressure and alignment help to gradually straighten the material. Roll straighteners can handle a variety of metals, including steel, aluminum, and copper, making them versatile tools within the fabrication domain.
