Operating a leveler requires training and skill, but computers are making the task much easier. A computer can quickly set the machine to a good starting point and allow very fine adjustment of the back-ups. Once the leveler is delivering good results on a particular coil, the settings can be saved and called up later. That saves setup time when coils are partially run and then sent back to stock.

As manufacturing has moved overseas, the U.S. slitting market has become saddled with overcapacity. Coil processors can improve efficiencies by upgrading the equipment they use in the following areas: coil storage, changeovers in coil and slitting tooling; scrap handling; and tensioning.

Because metal fabricators and OEMs have increasingly strict requirements, many suppliers of sheets and blanks must provide high-quality metal stock in terms of flatness, finish, and dimensional accuracy. Competition for every bid is tight, making it easy to take the quality for granted. If every...

Multiblanking lines are used to produce small, accurately shaped blanks directly from large coils. Modern lines can process many different types of material over a range of thicknesses, while still allowing quick changeovers and minimal maintenance. New technology is available in several key areas that limit the capacity of a typical multiblanking line, which include leveling, slitting, feeding, shearing, and stacking.
