Decoiler Machine
Heavy-Duty Coil Handling for Reliable Uncoiling Operations
Made in India
30+ Years
Product Overview
Decoilers are the critical first component in any coil processing line. Our heavy-duty decoilers are engineered to handle massive coil weights while providing smooth, controlled payoff. With hydraulic expansion mandrels, motorized or non-motorized options, and robust construction, these machines form the reliable foundation of your processing line. Available with optional coil cars for automated loading, our decoilers minimize changeover time and maximize production uptime.

How Does a Decoiler Machine Work?
A decoiler (also called uncoiler or payoff reel) is essential coil handling equipment that holds metal coils and unwinds them at controlled rates for downstream processing. The decoiler is the first component in any coil processing line and its reliable operation is critical for consistent production.
Coil Loading
The coil is transported to the decoiler by crane, forklift, or coil car. The coil is positioned on the mandrel (expanding drum) with proper centering.
Mandrel Expansion
The hydraulic or pneumatic system expands the mandrel segments outward to grip the coil inner diameter securely. This prevents coil slip during unwinding.
Coil Preparation
The hold-down arm (if equipped) secures the coil outer wrap. The peeler (if equipped) lifts the strip end for threading into the line.
Strip Threading
The operator feeds the strip end through pinch rolls and into the downstream equipment. Initial threading may be manual or assisted.
Controlled Unwinding
The decoiler unwinds the coil at controlled speed synchronized with line demand. Motorized decoilers use VFD drives; brake types use friction control.
Tension Control
Proper back-tension is maintained throughout unwinding to prevent strip sagging or over-tensioning. This ensures smooth feeding to the processing line.

Key Components of a Decoiler
Decoilers are engineered with robust components designed for reliable operation with heavy coils. Understanding each component helps in proper operation and maintenance.
| Component | Function |
|---|---|
| Base Frame | Heavy-duty fabricated steel structure providing stable foundation for all components. |
| Mandrel (Expanding Drum) | Holds the coil by expanding against the inner diameter. Hydraulic or pneumatic expansion. |
| Drive System | AC motor with VFD (motorized) or brake system (non-motorized) controls unwinding speed. |
| Hold-Down Arm | Pneumatic or hydraulic arm that presses on the coil OD to prevent loose unwinding. |
| Peeler | Lifts the strip leading edge from the coil for easy threading. May be hydraulic or pneumatic. |
| Coil Car (Optional) | Motorized carrier that transports coils to the decoiler for safe, efficient loading. |
| Threading Table (Optional) | Guides the strip from decoiler to the processing line during initial threading. |
