Roll forming machines use long metal strips to make a specific configuration, the most common being coiled steel. In most applications, the required cross-sectional profile is designed for the machine to bend the metal if necessary.
In addition to roll forming, these machines perform many metalworking tasks, including material cutting and roll stamping.
Most of the roll forming machines work in a continuous cycle. The material is fed into the machine, and at each stage of each operation, the material continues to enter and the final product is completed.
