The basics of roll form tooling design

Side rolls, or rolls that are mounted on a vertical axis and located between passes, are excellent for helping a profile enter the main roll passes. In addition to smoothing out the forming transition between passes, side rolls also reduce scuffing of the vertical legs because they spin on the same axis that the profile travels.

An Overview of Cold-Formed Steel Structures

2). A simple section may require as few as six pairs of roll, but a complex shape can require as many as 24 to 30. The thickness of material that can be formed generally ranges between 0.004 (0.10mm) up to 0.312 inches (7.9mm), although heavy duty cold forming mills can handle steel up to ¾ of an inch (19mm) thick.
