A plug-and-work coil feeding station engineered for rapid deployment on any roll forming line. Independent external control box with intuitive start/stop, emergency stop, and speed dial — new operators reach full productivity within five minutes.
Every roll forming production line begins at the coil. A reliable decoiler determines whether the downstream forming machine receives smooth, constant-tension material or suffers from jerky feed, edge misalignment, and premature roller wear. Our electric decoiling machine is purpose-built to bridge the gap between raw steel coil and precision forming — delivering steady unwinding for galvanized, color-coated, and Al-Zn steel coils from 0.3 to 1.0 mm.
It pairs seamlessly with Xinnuo's metal roofing machine lineup and integrates into any existing production line. Learn more about our three decades of manufacturing heritage and the 140+ countries we serve.
No buried panels, no cramped machine-side buttons. The decoiler ships with a standalone external control box mounted at operator waist height, featuring large, clearly labeled controls:
Three industrial-grade push-buttons — green start, red stop, and a mushroom-head emergency stop that physically latches. A single palm strike cuts all power. Compliant with CE safety requirements for operator protection.
A graduated rotary potentiometer gives the operator real-time speed adjustment from 0 to maximum decoiling speed. Match the unwinding pace to the downstream forming machine in seconds, without touching any internal wiring.
All control cables enter the box through sealed PG glands. Internal terminals are clearly numbered, bundled with cable ties, and protected by an IP54-rated enclosure. Neat, traceable, and immune to workshop dust and water spray.
Three buttons, one knob. That is the entire operator interface. There is no touch screen to navigate, no multi-layer menu, no password lockouts. A new hire can load a coil and start feeding material after a single demonstration.
The electric decoiler is not an isolated island. Its control circuit exposes dry-contact terminals for direct PLC signal exchange with downstream forming machines. When the forming line's master PLC issues a feed command, the decoiler unwinds; when the forming line pauses for shearing, the decoiler stops in sync. This closed-loop handshake eliminates coil slack, prevents material pile-up, and keeps the entire line running as one coordinated system.
For multi-machine workshops, a single operator can monitor the decoiler status from the main forming machine's HMI — no need to walk back and forth adjusting separate controls.

The manual expansion mandrel tightens with a hand wheel — no hydraulic pump, no compressed air, no special tools. One worker loads a 5-ton coil in under three minutes.
A friction brake band on the mandrel shaft prevents free-spinning when the motor stops. Adjustable tension keeps the strip flat and wrinkle-free as it enters the forming machine.
Full-coverage steel guard over the chain and sprocket assembly meets CE machine safety directives. Zero exposed pinch points during operation.
Standard mandrel diameter fits 99% of 0.3–1.0 mm roof sheet coils on the market. Compatible with every Xinnuo forming machine and most third-party lines.
