Double Cone vs. Single Arm Uncoiler – Which One to Choose?

Double Cone vs. Single Arm Uncoiler – Which One to Choose?

When selecting an uncoiler for your coil processing line, choosing the right structure is critical to ensuring efficiency, stability, and long-term reliability. Two commonly used types are the Double Cone Uncoiler and the Single Arm Uncoiler. Each has its strengths and ideal use cases.

🔷 Double Cone Uncoiler

Best for: Heavy coils, high-precision alignment, continuous production lines

Advantages:

• Excellent Coil Centering – The symmetrical cone system provides automatic, precise centering of the coil.

• Superior Stability – Ideal for heavy coils, the base and dual-cone support eliminate tilting or vibration.

• Quick Changeover – Minimal repositioning needed when switching coils.

• Safer Handling – Reduces manual intervention and risk of coil slipping.

Typical Applications:

• ERW tube mill lines

• Slitting & cut-to-length lines

• Cold roll forming systems

• High-speed automated lines

🔸 Single Arm Uncoiler

Best for: Light to medium coils, compact space, budget-sensitive projects

Advantages:

• Lower Cost – Simple structure, fewer components.

• Space-Saving Design – Smaller footprint for compact production areas.

• Manual or Hydraulic Expansion – Suitable for lighter-duty requirements.

• Easier Maintenance – Fewer moving parts mean lower maintenance.

Typical Applications:

• Entry-level roll forming lines

• Manual or semi-automatic coil setups

• Thin gauge material processing

🔍 Which One Should You Choose?

✅ Recommendation

If you are handling heavy-duty coils, require stable operation, and aim for automation, the Double Cone Uncoiler is the preferred choice.

If your needs are lighter, your space is limited, or you are running a budget-sensitive project, then the Single Arm Uncoiler may suffice.
