DSLS Series Slitter Rewinder Machine​

 

The equipment is mainly used for the production of lithium battery separator slitting. The main task is to divide the original wide rolled lithium battery separator into lithium battery separators of different sizes and widths through unwinding, transmission mechanism, and slitting mechanism, and complete the winding process.

• Function
