# Industrial Specification: Decoiler / Uncoiler

## 1. Technical Definition
A mechanical device that unwinds coiled metal strips or sheets from a coil for feeding into subsequent processing equipment.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 m/s linear strip speed, 0.1-0.3 MPa mandrel clamping pressure, 0.05-0.15 mm strip edge runout tolerance**. Failure boundary: **Mandrel slippage occurs at &gt;0.35 MPa clamping pressure differential, strip buckling at &gt;0.2 mm edge runout, bearing seizure at &gt;80°C operating temperature**, Mechanism: **Coulomb friction limit exceeded between mandrel and coil ID (μ=0.15-0.25), Euler buckling instability in thin-gauge strips (E=200 GPa steel), lubricant film breakdown in tapered roller bearings (ISO VG 32)**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.

| Symbol | Variable Definition | Localized Reference |

- **Caution**: 

### Q: What types of materials can your decoiler handle?
**A**: Our decoilers are designed to handle various coiled materials including steel, aluminum, copper, and other metal strips or sheets, with customizable mandrel sizes and tension settings for different material thicknesses and coil weights.

### Q: How does the tension control system work in your uncoiler?
**A**: Our uncoilers feature either a dancer arm or electronic tension sensor system that monitors material feed. This regulates the drive motor and braking system to maintain consistent tension, preventing material sagging or over-tightening during unwinding.

### Q: What maintenance is required for industrial decoilers?
**A**: Regular maintenance includes lubricating bearings and shafts, inspecting expansion pads for wear, checking brake system alignment, and verifying electrical connections. We recommend quarterly inspections and annual comprehensive servicing for optimal performance.
