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.
