Decoiler machines are widely used in the processing and manufacturing industry for feeding and decoiling materials. They can also be used for winding processed finished materials or waste materials. However, there is a significant difference between feeding and winding for some soft materials, making the decoiling action difficult and not smooth. In this article, we will discuss the modifications needed for a decoiler machine to make the winding of soft materials smoother.

Guiding and Tensioning Devices for Soft Materials

The stamping automation industry generally recognizes that the effective method for winding soft materials using a decoiler machine is to install a guiding and tensioning device. There are mainly two types of guiding devices that can be added to a decoiler machine: one is to tension the winding material directly through pulling means. However, when the required material for guiding has both softness and elasticity, the winding material will sometimes appear in an unstable state of tight pulling and relaxation (shaking), which will cause the decoiler machine to be prone to deformation errors, affecting the quality of the wound product.

Damping Devices for Stable Guiding

The other type of guiding device is to set a damping device on the guiding device of the decoiler machine, which makes the guiding of the material have a suitable tightness. This structural design can make the guiding of the material tend to be stable and alleviate the shaking and vibration phenomenon. However, the damping device added to the decoiler machine still easily causes the material to be too tightly pulled and shrinks, which cannot solve the problem of the accuracy and quality of the wound product being affected.

Modifications for Smooth Winding of Soft Materials

To improve the winding of soft materials, modifications are needed in the decoiler machine design. One solution is to add a sensor to detect the winding tension of the material in real-time, and then adjust the speed of the decoiler machine or the tension of the winding material through the control system, to maintain a stable tension and prevent deformation errors.

Another modification is to use a servo motor to drive the decoiler machine instead of a traditional motor. A servo motor can precisely control the speed and torque of the decoiler machine, ensuring stable and smooth winding of soft materials.


The decoiler machine is a commonly used equipment in the processing and manufacturing industry, but it can face challenges when winding soft materials. To solve this problem, modifications such as adding a sensor or using a servo motor can be implemented to maintain stable winding tension and prevent deformation errors. These modifications can significantly improve the accuracy and quality of the wound product, making the decoiler machine more efficient and effective.
