In the realm of automated stamping production lines, the decoiler—also known as an uncoiler—is an indispensable component, tasked with unwinding and feeding sheet material coils. While there are various types of decoilers, traditionally, the flat decoiler (or disc decoiler) has been the go-to for high-speed decoiling. However, flat decoilers have their limitations, including suitability only for thin, narrow materials, low load capacity, and limited customization options for reel diameter. These constraints render them increasingly inadequate for the demands of modern high-speed stamping.

The Need for Advanced Decoiling Solutions

As the need for high-speed stamping production grows, a new high-speed heavy-duty decoiler has emerged. Developed from traditional heavy-duty decoilers, this new model combines high load capacity, wide applicability, and extensive customization with the capability to achieve high-speed decoiling at up to 30 meters per minute. It marks a significant advancement in decoiling technology.

Key Features of the High-Speed Heavy-Duty Decoiler

The high-speed heavy-duty decoiler stands out due to its enhanced design and structure. The most notable advancements include an improved expansion mechanism utilizing a dual-expansion reel and the integration of a crank locking device, eliminating the need for a sliding sleeve with an inclined wedge surface.

Improved Expansion Mechanism

In the high-speed heavy-duty decoiler, the central pull rod, driven by spring pressure, moves sector-shaped support tiles along the inclined wedge surface. The crank locking device keeps the reel in its expanded state, ensuring stability. The dual-expansion structure allows the reel’s expansion range to be nearly double that of a single-expansion reel. This design facilitates easy fitting of collapsed coils onto the reel and ensures uniform, minimal elastic deformation during decoiling.

Enhanced Stability and Performance

This innovative design effectively addresses issues of high rotational resistance and difficult material feeding that often plague high-speed decoiling processes. The larger gaps between the sector-shaped support tiles contribute to smoother operation, ensuring stable performance even at high speeds.

Benefits of the High-Speed Heavy-Duty Decoiler

High Load Capacity

The new decoiler supports a high load capacity, making it suitable for a wide range of materials, from thin to thick sheet coils. This versatility is crucial for meeting diverse production needs in modern stamping lines.

Wide Applicability

The high-speed heavy-duty decoiler is designed to handle various materials, including thin, medium, and thick sheet coils. This broad applicability ensures it can meet the needs of different production environments, enhancing its utility across various industries.

Customization Options

Customization is a key feature of the high-speed heavy-duty decoiler. The load capacity and inner and outer diameters of the coil can be tailored to specific production requirements. This flexibility allows manufacturers to optimize their production lines for efficiency and performance.


The introduction of the high-speed heavy-duty decoiler represents a significant leap forward in decoiling technology. By combining the strengths of traditional heavy-duty decoilers with advanced design improvements, this new model addresses the limitations of older decoilers and meets the high-speed demands of modern stamping production. Its high load capacity, wide applicability, and extensive customization options make it an invaluable asset for manufacturers looking to enhance their production capabilities. As the industry continues to evolve, the high-speed heavy-duty decoiler is set to play a pivotal role in driving efficiency and performance in automated stamping lines.
