ROLL FORMING (CONTOUR ROLL FORMING)

(also known as roll forming or cold roll forming) is a continuous process for forming metal from sheet, strip, or coiled stock into desired shapes by feeding the stock through a series of roll stations equipped with contoured rolls called roller dies. Most contour roll forming is done by working the stock progressively in two or more stations until the finished shape is produced.

Contour roll forming requires less force and offers the ADVANTAGE of theoretically unlimited length as the material need only pass through the rollers. However, they still employ the basic principle of bending the metal beyond its elastic limits. As a result, contour roll forming machines strengthen the metal just like stretch forming machines.
