Key Design Features
1. Precision Winding for Small to Medium Cylindrical Cells
We engineered this machine specifically for cylindrical cell formats with winding diameters from φ14 to 26mm. It accommodates various electrode and separator widths, making it versatile for different battery designs.
2. Adjustable Winding Parameters
You can easily adjust the winding needle diameter (φ4 standard, φ3.5 optional), diaphragm tension, and termination tape settings. This flexibility allows you to optimize the winding process for your specific cell chemistry and format.
3. Constant Tension Control
The machine maintains constant, adjustable tension on the diaphragm throughout the winding process. For the positive and negative electrodes, we use vacuum adsorption to ensure precise placement without slippage.
4. PLC Control with User-Friendly Interface
We equipped the GN-WS70 with a PLC control system that simplifies operation and ensures repeatable results. The intuitive interface allows operators to set parameters quickly and monitor the winding process in real time.
5. High Precision and Consistency

How the Winding Process Works
Step 1: Material Loading
First, you load the positive electrode, negative electrode, and separator rolls onto the machine. The diaphragm roll mounts on a 3-inch core, and you set the desired width and tension parameters via the PLC interface.
Step 2: Parameter Setup
Next, you configure the winding parameters: needle diameter, winding diameter, tape settings, and tension values. The machine stores these settings for repeatable production runs.
Step 3: Automatic Winding
When you start the cycle, the machine begins winding the electrodes and separator around the winding needle. The constant tension control ensures the diaphragm remains taut, while vacuum adsorption holds the electrodes securely in place. The system automatically applies the termination tape at the end of the winding cycle.
Step 4: Ejection
After completing the programmed number of windings and tape application, the finished jelly roll ejects automatically. You then transfer it to the next process, such as housing insertion or electrolyte filling.
Step 5: Quality Monitoring
Throughout the process, the PLC monitors critical parameters. The machine achieves ±0.03mm diameter precision and ±0.05mm height precision, ensuring consistent cell quality.
