In the sheet metal industry, a cut to length line is a popular method of creating flat, rectangular blanks from larger metal coils. This method is also known as a CTL or a blanking line, and many suppliers’ cut to line machine will uncoil the larger material or master coil, straighten or flatten it, and then cut it to the required length as it moves through the line, and most of all, ultimately stack it into a bundle for convenient purposes.
Because steel does not come off of a larger coil in a flat form, it needs to be stretched into flatness while on the CTL process. And many of the cut to length line suppliers use roller leveling technology to stretch and compress the materials because this method increases flatness tolerance and material stability in a significant way. The ultimate use of the cut material may warrant precision cutting accuracy that meets the exact specifications for the end-users in different markets.
