Roll forming lines can be set up with multiple configurations to punch and cut off parts in a continuous operation. For cutting a part to length, the lines can be set up to use a precut die where a single blank runs through the roll mill, or a postcut die where the profile is cutoff after the roll forming process.
You can successfully rollform a profile more than one way. In fact, many roll form designers take different approaches to design and development. Also, because the roll forming process has a seeming limitless capacity to produce complex profiles with just as many variables, many roll form designs are oneofakind; therefore, theory can go only so far.
