iTOKO high speed Slitting Line is used to create multiple widths or “mults” from a wider master coil. The mults are made from predetermined widths. The slitter consists of three main parts: an uncoiler, slitter, and recoiler. The material is fed from the uncoiler, through the nip between the two circular cutting wheels (one on top and another underneath), and then re-wound in slit mults on the recoiler. The slitting process has been referred to as part art and part science. It is important that the equipment supplier and end user work in concert so the proper components, arbor size, tooling package, horsepower and tensions are suitable for the material to be slit.

We are a leading manufacture in the industry with high speed slitting, automatic coil feeds and hands free coiling. Used for cutting narrow coil strips from main coils, our machinery comes in many widths and thickness and processes at speeds up to 280m/min.

The process begins with loading a steel coil or master coil onto the uncoiler. The uncoiler can be a dual cone type for heavy gauges or a single end expanding mandrel type for heavy or light gauges. The coil can be loaded into the cones via a pusher type ramp or via a turnstyle and coil car that threads the mandrel of the single end into the inner diameter of the master coil. The hold down presses onto the outside diameter of the master coil and the bands are cut on the master coil. The coil is rotated off the cones or mandrel and peeled to allow the head of the coil to enter edge guides prior to the flattener and leveler (if flatness is critical in downstream operations). Next, The slitter, which consists of two parallel arbors mounted with rotary cutting knives.
