The slitter line is a line designed and expressly dedicated to the production of strips in rolls of various widths, that are prepared in rolls and then sent to the production lines. The first process involves loading the roll on a cradle and then its loading on the decoiler placed at the beginning of the line. The operator cuts the steel straps and feeds this strip into the introducer. From this point, the operation proceeds semi-automatically: the strip goes into the heading unit then to the shear with circular blades which divides the coil in smaller strips of the desired width. Continuing in semiautomatic mode, the strips go to the the felt-press with latch and get attached to the recoiler. From this point, processing can continue automatically until the strip on the first decoiler is finished. The strips are placed on an unloading cradle, closed with steel strap and sent the the production lines.
