Coil unwinding is a pivotal step in various industrial processes, requiring precision and efficiency. One essential tool that plays a vital role in this process is the decoiler. This specialized apparatus is designed to carefully unfurl coiled materials, setting the stage for subsequent procedures like leveling and feeding. In this article, we delve into the world of coil unwinding technology, exploring the advantages of a revolutionary alternative: the lightweight decoiler.

Understanding Decoilers: Types and Challenges

Decoilers come in two primary types, each tailored to specific materials. The first is designed for unwinding medium to thick plate materials, while the second, known as a flat electronic feed unit, is geared towards thin plate materials. The flat electronic feed unit serves as a horizontal decoiler, with the coil material’s axis positioned horizontally for seamless unwinding.

While the flat electronic feed unit serves its purpose well, it isn’t without limitations. The weight and inertia of the coil material during unwinding and output processes pose challenges in initiating and stopping the unit. Additionally, sagging after output leads to dragging forces on the material, complicating control over unwinding speed and length. This can result in excessive unwinding, causing material pileup and compromising its flatness, subsequently burdening subsequent leveling processes.

Elevating Efficiency: Introducing the Lightweight Decoiler

In the realm of coil unwinding, a game-changing solution often overlooked is the lightweight decoiler. Unlike its counterparts, this vertically oriented apparatus is exclusively crafted for lightweight coil materials. Let’s explore how this innovative decoiler operates and its compelling benefits.

Effortless Unwinding Process

Operating the lightweight decoiler is an exercise in simplicity and efficiency. The coil material to be unwound is suspended and placed on the material support tile of the decoiler. The coil material’s inner hole aligns with the material support tile, setting the stage for the unwinding process. By tightening the handle, the expansion sleeve moves downward, causing the material support tile to shift outward through the wedging action of inclined wedges. Guide blocks aid in this movement, ensuring a secure connection between the coil material and the vertical shaft.

Consistent Pressure, Optimal Performance

The driving device of the decoiler propels the pressing roller arm into rotation, maintaining a steady pressing force against the coil material through the pressing roller’s action. During unwinding, the coil material rotates at a constant linear speed, driven by the pressing roller motor. Notably, the engagement clutch between the vertical shaft motor and the decoiler’s vertical shaft remains disengaged, allowing the vertical shaft motor to stay uninvolved in the unwinding transmission.

Seamless Retraction and Safety

Upon completing the unwinding process, engagement of the clutch between the vertical shaft motor and the decoiler’s vertical shaft initiates. This prompts the vertical shaft motor to reverse, effectively retracting any excess unwound material. This straightforward yet ingenious process ensures safety, practicality, and a seamless workflow.

Lightweight Decoilers: A Paradigm Shift

The benefits of adopting lightweight decoilers are undeniable. By opting for this vertically oriented solution, industries can mitigate the challenges posed by traditional flat electronic feed units. The lightweight decoiler’s streamlined design and efficient unwinding process translate to enhanced productivity and reduced operational complexities.


In the realm of coil unwinding, innovation takes center stage with the introduction of the lightweight decoiler. This vertically oriented apparatus offers a solution that addresses the limitations of conventional flat electronic feed units. With its effortless unwinding process, consistent performance, and safety features, the lightweight decoiler sets a new standard for coil material handling. Embracing this paradigm shift in coil unwinding technology promises increased efficiency, reduced production costs, and a competitive edge in today’s industrial landscape.
