Introduction: The Role of Slitting Lines in Metal Coil Processing
In the steel, aluminum, copper and other coil-based industries, slitting lines are essential for tranforming large master coil into narrower coils suited for further processing - like stamping, tube forming, roll forming, or pressing.
A high performance slitting line helps optimize material usage, reduce handling costs, and speed up production.
At Kinbenz, we manufacture custom slitting lines tailored for different materials, thickness ranges, width ranges and various industry requirements.
What Is a Metal Coil Slitting Line?
A metal coil slitting line is an industrial processing machinery that unwinds a master coil, slices it into multiple narrower strips, and rewinds those strips into smaller coils - all at high speed and with high precision.
How Does a Metal Coil Slitting Line Operate?
Step 1: Coil Loading and Uncoiling
- A loading coil car loads the metal coil onto the uncoiler
- The uncoiler unwinds the coil at a controlled speed
- Hydraulic expansion holds the coil tightly in place
Step 2: Coil Leveling and Pinch Roll Feeding
- The strip passes through a pinch roll and leveling device to align the coil edges
- It ensures the material feeds staight into the slitter without deviation
Step 3: Slitting (Main Cutting Process)
- The coil enters the slitter, where circular blades mounted on upper and lower shafts cut the strip
- Each blade position corresponds to the desired strip width
- Scrap edge trims are separated using edge trimmers and scrap winders
Step 4: Tension Control & Loop Pit
- After slitting, the strips enter a loop pit then tension station to absorb slack and stabilize feeding
- Proper tension prevents coil buckling or wrinkling during rewinding
Step 5: Recoiling
- Each slit strip is rewind into an individual coil on the recoiler
- A separator unit helps guide each strip and avoid overlap or scratching
- At the end of the process, finished coils are strapped and removed by an unloading car

Q: Can I request a customized slitting width setup?
A: Sure. All machine in Kinbenz can be tailored for your detailed requirements! Just let us know!
Q: What's the difference between slitting and cut to length line?
A: Slitting Line cuts coil into narrower coils, while Cut to Length Line cut the coil into flat sheets.
