The steel coil is lifted onto the decoiler mandrel, which expands to grip the inner diameter. As the line pulls strip forward, the decoiler rotates and pays out material at a controlled speed. A brake or dancer arm regulates tension so the strip feeds smoothly into the straightener or press. Double-head decoilers add a rotating turret so one coil runs while the next is pre-loaded on the second mandrel.
Decoiler
Steel Coil Decoilers for Every Stamping Line Size
A decoiler is the first station in any coil-fed press line: it holds the steel coil, controls payout tension, and feeds strip to the straightener or press. FANTY manufactures manual, hydraulic, motorized, double-head and flat decoilers as a factory-direct builder. Tell us your coil weight, width and material, and we will recommend the right decoiler type and configuration for your line.
What a Decoiler Does for Your Line
Hydraulic & manual expansion
Hydraulic mandrels expand to grip coils up to 20 tons; manual mandrels suit lighter, budget-conscious setups.
Tension-controlled payout
Pneumatic or induction brakes keep strip tension steady as coil diameter decreases, preventing snags and nesting.
Double-head fast changeover
Dual mandrels let you pre-load a second coil while the first runs, cutting changeover time to under two minutes.
Line-compatible footprint
Frame dimensions, mandrel sizes and mounting interfaces are configured around your existing straightener or feeder.

Where Decoilers Earn Their Keep
Automotive stamping
Chassis brackets, seat frames and structural members from steel coil.
Electronics & connectors
Precision terminals, shielding cans and lead frames from thin strip.
Appliance manufacturing
Washing-machine drums, refrigerator cabinets and metal enclosures.
Metal furniture
Table bases, chair frames and shelving from light-gauge coil.
From Inquiry to Installation: How FANTY Works
Coil loading
The coil is lifted onto the mandrel by crane or coil car.
Mandrel expansion
Manual or hydraulic expansion grips the coil ID firmly.
Tension set
Brake or dancer arm tension is set to match the line pull.
Strip threading
The strip head is threaded into the straightener or feeder.
Continuous unwind
The decoiler pays out strip at line speed while maintaining tension.

Our team answers technical questions before purchase and supports installation and spares afterwards.
Decoiler Frequently Asked Questions
Which decoiler type fits my coil size?
Manual and flat decoilers suit lighter coils up to a few hundred kilograms; motorized and hydraulic decoilers handle coils from 3 tons to 20 tons. Tell us your coil OD, ID, width and weight and we will size the mandrel, frame and brake accordingly.
What is the difference between manual and hydraulic expansion?
Manual expansion uses a hand wheel or screw to wedge segments outward; hydraulic expansion uses a cylinder to open the mandrel quickly and apply uniform pressure, which is safer for heavy coils.
When should I choose a double-head decoiler?
Double-head decoilers are ideal for high-volume lines where coil changeover time matters. Pre-load the second coil on the spare mandrel and rotate the turret to swap in under two minutes.
What strip widths and thicknesses are supported?
Across the family: strip widths up to 1,600 mm and coil weights from 200 kg to 20,000 kg. Each model family has its own envelope; our engineers match the model to your coil size.
Can I integrate the decoiler with my existing straightener and feeder?
Yes. FANTY also builds complete coil handling lines (decoiler + straightener + feeder). We can supply the full package or engineer the decoiler to match upstream equipment already on your floor.
What about controls, training and spares?
Heavy-duty models include a control panel with jog, tension and speed settings. English manuals, video guides and a starter spare-parts list are supplied, and remote commissioning support is available.
