How Does a Decoiler Work?
A decoiler is a machine that helps to unwind and straighten steel coils. It is used to prepare coils for further processing such as stamping, drawing, or cutting. The steel coils are first loaded onto the decoiler mandrel. The decoiler then uses hydraulic pressure to expand the mandrel and uncoil the steel coil. The tension on the steel coil can be adjusted to ensure that it is unwound smoothly and evenly. Once the steel coil has been unwound, it can be cut to length or fed into another machine for further processing.
What is The Maximum Coil Weight a Decoiler can Handle?
Maximum weight of each coil is 3000 lbs. Width is up to 27 inches / 670mm. Decoiler can be used to uncoil metal, plastic,.

Operating Instructions for the Decoiler
1. Turn on the 380V three-phase power supply, start the decoiler, check the actual rotation direction, the material should be fed upwards, and the vertical material should be in the direction of the 24V induction frame. (Of course, we will configure the power conversion for your local usage)
2. According to the thickness of the material and the position of the coil leveler or feeder machine, adjust the distance and position of the decoiler so that the material can smoothly enter the coil leveler or feeder machine. If only the coil feeder machine is used, a certain waiting area should be adjusted according to the feeding length. When the height of the center of the decoiler is basically equal to the working surface of the punch press, the distance from the feeding port of the feeding device is 4 meters to 4.5 meters. When it is too high or too low, appropriately increase the feeding distance and adjust the direction of the discharge.
3. Turn the handle of the decoiler counterclockwise to adjust the diameter of the support plate (smaller than the inner diameter of the material). Load the coil material, turn the handle of the decoiler clockwise, tension the inner circle of the coil material, and then install the baffle plate on the other two material plates. It should be noted that according to the material, the baffle plate cannot clamp the coil material too tightly, and there should be a gap of 2-5mm, otherwise it will affect the discharge. Turn the decoiler handle clockwise to hold the coil material tightly.
4. According to production needs, adjust the height of the 24V induction frame and properly control the length of the discharge.
5. It is inductive control during automatic operation, and the feeding speed can be directly adjusted on the panel. If manual function is required, first select the manual adjustment direction (forward/reverse) on the panel, and then press the jog, and the speed can also be adjusted.
6. If there is an abnormal phenomenon in the feeding of the decoiler, you should press the emergency stop switch immediately, and the press punching machine will also stop at the same time. After recovering from the abnormality, reset the emergency stop switch (turn off) first, and then the press punching machine can be officially started.
How to Choose The Right Decoiler
Load capacity
Decoilers have standard load capacities, but customizations are required for coils exceeding the standard weight. Determine the maximum coil weight the decoiler can handle. ensure it matches or exceeds the weight of the coils you typically use.
Material width and thickness
The material’s thickness plays a crucial role in determining the appropriate decoiler. For materials with a thickness exceeding 2mm, it is advisable to add a pneumatic pressure arm to the decoiler. This arm prevents strip scattering and provides rotational force during the uncoiling process.
Motor and drive type
Consider whether you need a motorized or manual decoiler. motorized decoilers offer higher efficiency and are suitable for heavier coils and continuous production lines.
Control system
Our advanced decoilers can operate independently with a sensor arm that automatically adjusts the coil feeding. They do not require programmable settings and function as standalone devices. Emergency stop circuits are connected to the main machine for safety. These systems can also be integrated into a PLC (programmable logic controller) system for more advanced control and automation.
Types of Decoiler
Manual decoilers
Ideal for small-scale operations or when handling lighter coils. They require manual adjustment and continuous and smooth pulling or feeding.
Motorized decoilers
Suitable for larger, heavier coils and continuous production lines. Motorized decoilers are advisable if the roll forming machine frequently stops. These are powered by electric motors and can be integrated with automated systems.
Double-head decoilers
These have two heads to hold two coils, allowing for quick changeovers and reduced downtime. Ideal for high-volume production.
Hydraulic decoiler
Thanks to their different models, they can open coils between 6 tons and 30 tons. In hydraulic decoilers, the process of attaching and removing the roll to the machine can be done very easily. Hydraulic decoilers can easily open coil sheets without breaking.
