How Does a Slitting Line Work?
A slitting line is a metal processing system that converts wide master coils into multiple narrower strips of precise widths. The process uses rotary circular knives mounted on arbors to make continuous longitudinal cuts through the metal strip. Understanding the slitting process helps you optimize production efficiency and output quality.
Coil Loading & Decoiling
The master coil is loaded onto the decoiler using a coil car. The hydraulic expansion mandrel grips the coil securely. The strip is then fed into the line at controlled speed.
Strip Straightening
The material passes through pinch rolls and a straightener to remove coil set and ensure the strip enters the slitter head flat and aligned.
Precision Slitting
Rotary circular knives mounted on upper and lower arbors cut the strip into multiple narrower widths. Knife overlap and clearance are precisely set for clean, burr-free edges.
Scrap Collection
Edge trim (scrap) from both sides is separated and wound onto scrap winders for recycling. This ensures only usable strips proceed downstream.
Tension Control
The slit strips pass through a loop pit or tension station where controlled tension is applied to each strip individually before recoiling.
Recoiling
Individual strips are wound onto the recoiler with separator discs between each coil. Proper tension ensures tight, uniform coils ready for shipment or further processing.

Key Components of a Slitting Line
A complete slitting line consists of several precision-engineered components working in synchronization. Each component plays a critical role in achieving consistent output quality.
| Component | Function |
|---|---|
| Decoiler | Holds and unwinds the master coil at controlled speed. Features hydraulic expansion mandrel and optional coil car for safe loading. |
| Pinch Roll Unit | Guides the strip into the line and maintains proper tension between decoiler and slitter head. |
| Edge Trimmer (Optional) | Removes damaged or irregular coil edges before slitting for consistent strip widths. |
| Slitter Head | The heart of the line—precision circular knives on arbors perform the actual cutting. Adjustable for various width combinations. |
| Scrap Winder | Collects and winds edge trim into manageable coils for recycling. Automatic ejection for continuous operation. |
| Loop Pit / Looper | Creates a buffer zone allowing speed variations between slitting and recoiling. Maintains strip tension. |
| Tension Station | Applies individual tension to each slit strip ensuring tight, uniform recoiling. |
| Recoiler | Winds finished strips with separator discs. Features expanding drum and provisions for strapping. |
