This is a must, especially for pre-cut blanks. The pre-cut lengths must self-feed through every pass without damaging the lead edge of the strip. A good rule of thumb is to try to design all roll passes to self-feed even when running coil stock. The mill operator should not have to feed a new coil and “pry” the section into the next pass.
