In the realm of stamping production, the choice between horizontal decoilers and the more cost-effective vertical feeding machines has long been a pivotal decision. While the latter boasts economic pricing, robust load capacity, versatile thickness applicability, and customizable coil diameters, a glaring drawback inhibits its seamless operation. The vertical single-coil feeding method, while efficient, comes at the cost of interrupting the production flow during coil replacement, leading to significant downtime.

The Predicament of Vertical Feeding Machines

Vertical feeding machines, favored for their economic appeal and versatility, face a critical challenge—the inability to stack coils directly. As a consequence, each time a coil is depleted, the entire production line grinds to a halt. The cumbersome process of loading materials using forklifts or overhead cranes, especially with hefty coils, exacerbates the downtime. This downtime, incurred during coil replacement, becomes a bottleneck, impeding the overall efficiency of the stamping automated production line.

Innovative Solution: The Dual-Head Decoiler

To tackle the productivity hurdles posed by coil replacement in stamping production, a revolutionary solution has emerged—the dual-head decoiler. An evolution of the traditional decoiler, this cutting-edge equipment replaces the single feeding coil with a dual-coil configuration. The operational brilliance lies in the seamless transition of material supply between the two coils, eliminating the need for a production line standstill during coil replacement.

Effortless Coil Replacement Mechanism

The dual-head decoiler features two unwinding devices, each housing a coil and a feeding motor responsible for precise rotation. Positioned 180 degrees apart, these devices are interconnected by a rotating axis. As the leveling machine operates, the second coil is pre-mounted on the coil of the second unwinding device before the first coil depletes. Upon exhaustion of the initial coil, a 180-degree rotation of the axis seamlessly shifts the supply to the second coil. Simultaneously, as the second coil nears depletion, the third coil is ready on the coil of the first unwinding device. This continual installation of coils during machine operation eradicates the need for any pause in the stamping process for coil replacement.

Benefits of the Dual-Head Decoiler

  1. Continuous Operation: Uninterrupted production as coil replacement occurs seamlessly during machine operation.
  2. Time Efficiency: Drastically reduces downtime associated with coil replacement, enhancing overall production efficiency.
  3. Enhanced Versatility: Retains the economic advantages of vertical feeding machines while overcoming their inherent limitations.
  4. Adaptable to Heavy Coils: Handles excessively heavy coils without the need for extended pauses in production.


The dual-head decoiler stands as a game-changer in the stamping industry, mitigating the traditional challenges associated with coil replacement. Its innovative design ensures a constant material supply, translating to heightened efficiency and reduced downtime. In the dynamic landscape of stamping production, embracing this revolutionary equipment paves the way for unparalleled productivity and competitiveness.
