Colt Cradle Coil Straighteners

Heavy‑Duty Coil Handling for Thick‑Gauge Stamping Applications

PRI offers a full range of Colt Automation cradle‑style coil straighteners engineered for reliable performance in demanding blanking and heavy‑gauge stamping environments. These systems combine rugged coil support with synchronized straightening rolls to deliver smooth, consistent material flow into your press line.

Cradle straighteners are ideal for applications where coil loading efficiency, reduced downtime, and stable material control are essential.

System Overview

Colt cradle straighteners are designed for seamless coil loading and continuous production. When paired with optional coil storage ramps or buggies, operators can stage the next coil while the line is running—minimizing changeover time and maximizing throughput.

Each unit features:

• Self‑centering, adjustable side plates for secure coil containment
• Synchronized cradle rolls and straightener rolls for smooth material payout
• Optional hydraulic hold‑down arms for safe, controlled threading
• Optional coil storage racks or extended‑travel buggies for high‑volume operations

These systems are best suited for material thicker than 0.070", where stability and controlled uncoiling are critical.

Why Choose a Cradle Straightener?

• Excellent stability for heavy or wide coils
• Reduced risk of coil clock‑springing
• Faster coil loading compared to mandrel‑style uncoilers
• Ideal for thick‑gauge materials and high‑tonnage blanking
• Compatible with a wide range of press feed systems
