Automatic Double Head Uncoiler for ERW Pipe Making Machine
High-Efficiency Coil Handling Solution for Continuous Tube Production
The Automatic Double Head Uncoiler is an essential component in modern ERW Pipe Making Machines and Steel Tube Production Lines. Designed to maximize production efficiency and minimize downtime, this advanced uncoiling system allows operators to prepare the next coil while the current coil is running, ensuring continuous production and higher output.
Equipped with automatic expansion and contraction, automatic rotating and switching functions, pneumatic braking, and anti-loose strip baffle arms, the machine delivers stable, safe, and reliable coil feeding performance for various steel processing applications.
With a loading capacity ranging from 3 tons to 10 tons per side, the Automatic Double Head Uncoiler is suitable for small, medium, and large ERW tube mills.
Why Choose an Automatic Double Head Uncoiler?
In a traditional single-head uncoiler system, production must stop whenever a new coil is loaded. This interruption reduces efficiency and increases labor costs.
The Automatic Double Head Uncoiler eliminates this problem by providing two working stations. While one coil is feeding the production line, the second coil can be prepared simultaneously.
Benefits include:
- Reduced production downtime
- Increased line efficiency
- Faster coil changeover
- Lower labor requirements
- Stable strip feeding
- Improved production continuity
- Higher overall output
For modern tube manufacturing facilities, the double head uncoiler has become a standard configuration.
Main Features
Automatic Expansion and Contraction
The mandrel automatically expands and contracts through a hydraulic system, allowing quick and secure coil loading.
Advantages:
- Faster loading process
- Improved safety
- Stronger coil gripping force
- Reduced operator workload
Automatic Rotating and Switching
The double-head structure automatically rotates to bring the standby coil into the working position.
Benefits include:
- Minimal production interruption
- Smooth coil transition
- Increased production efficiency
- Continuous operation support
Pneumatic Braking System
The pneumatic braking system provides precise tension control during coil unwinding.
Features:
- Stable strip feeding
- Reduced strip vibration
- Improved forming quality

Working Process
- Load steel coil onto the standby mandrel.
- Hydraulic mandrel automatically expands and secures the coil.
- The active mandrel continuously feeds the production line.
- Once the running coil is consumed, the machine automatically rotates.
- The standby coil enters the working position.
- Production continues with minimal interruption.
This process significantly improves productivity compared to conventional single-head uncoilers.
