Simple Metal Coil Slitting Production Line

        Slitting machine is used to slit PPGI coil, aluminum coil, galvanized coil, stainless steel, carbon steel and other coils into several small strips along the length direction. The slitting ling mainly consists of uncoiler, leveling system, slitting system, shearing system, damping structure and  recoiler and so on. We can design and manufacture different specification according to different requirement of the client.

        Here I will introduce one type slitting line for the thin sheet. It could be used to process the thickness from 0.2 to 1.2mm and the coil width to 1250mm width.

The machine slitting speed can reach 15 to 20 meter per minute.

Damping StructureProvide tension force for the metal strip after slitting, so that it can be more neatly and tightly re-rolled into a steel coil on the winder.

The felt of the clamping mechanism can well protect the metal surface from scratches.
