Double Head Decoiler

Optimize your production line with our Passive double head decoiler—a high-efficiency decoiler engineered for uninterrupted roll feeding and minimum downtime. Featuring two roll stations—one active driver and one ready-to-run backup—this system slashes changeover time to keep your press and roll-forming operations running seamlessly. Ideal for high-speed press feeding in lamination processes and small roll-forming lines, our dual-head system boosts throughput, enhances continuity, and maximizes ROI. Upgrade to faster, more reliable decoiling today.

Brief Profile of Double Head Decoiler

Double head decoiler machine with two roll stations for continuous feeding

Enhance your continuous metal‐strip processing with our advanced decoiler machine. By powering one coil while the second remains on standby, it instantly switches to the backup roll as soon as the first is depleted—drastically reducing changeover time and minimizing production downtime. This seamless transfer also provides ample time to load spare coils without interrupting operation, ensuring consistently high throughput.
Designed for speed and reliability in serial manufacturing, this metal decoiler is often paired with an S‐loop straightener, a high‐speed gear unit and an H‐frame high‐speed press machine. This combination makes it the perfect choice for motor rotor and stator lamination stamping.

Double Head Decoiler FAQ

Q: What are the advantages of the dual-station design?
A: The two decoiling stations can work alternately. When one coil is finished, production can quickly switch to the other coil.
Q: What production modes is it suitable for?
A: It is suitable for long-term, high-volume, continuous production applications.
Q: What is the common applicable material width?
A: Standard models are typically suitable for coil widths from 200 to 400 mm.
Q: Why do many high-speed stamping lines choose a double head structure?
A: It reduces downtime during coil changes and helps maintain stable, continuous production efficiency.
Q: Is machine shutdown required when changing coils?
A: Under normal conditions, the next coil can be prepared in advance, allowing quick changeover and minimizing downtime.
Q: Which industries commonly use Double Head Decoilers?
A: They are widely used in electronics, motors, electrical components, precision hardware, new energy parts, and other industries.
Q: What products are commonly produced with this equipment?
A: Typical applications include electronic terminals, EI laminations, motor stators and rotors, connectors, precision stamped parts, and more.
Q: Can the two stations use different materials?
A: Yes. Different coil materials or specifications can be loaded according to production requirements.
Q: Can it work with high-speed presses?
A: Yes. It is suitable for high-speed continuous feeding and stamping applications.
Q: How does it improve production continuity?
A: While one station is feeding material, the other station can be prepared with the next coil, reducing waiting time.
Q: Is it suitable for 24-hour continuous production?
A: Yes. It is ideal for automated production lines requiring long continuous operation.
Q: What parameters are needed for model selection?
A: Material width, thickness, coil weight, coil inner diameter, and production speed should be confirmed.
Q: Is station switching complicated?
A: No. The control system is simple, and operators can use it efficiently after basic training.
Q: Can it be integrated with straightening and feeding equipment?
A: Yes. It can work together with straighteners and feeders to form an automatic stamping production line.
Q: What optional functions are available?
A: Optional features include coil hold-down devices, variable frequency speed control, automatic switching control systems, and more.
