ABSTRACT
Roll forming lines, unless they are fed with precut blanks, require an equipment to cut the strip or the
product to length. The cutting-to-length process can be ahead of the roll formingmill (precut), in-between
the forming stands ormills, after the roll formingmill, or after the last “in-line”operation (e.g., punchingor
curving). Presses are the most frequently used equipment for cutting. Occasionally, shears are used for
precutting and saws, lasers, plasma jets, or other methods for postcutting. Rotary devices can be used for
both pre-and postcutting.
