|
Production Speed
|
3m/min ≤ V ≤ 30m/min.
|
|
Laminating Machine Design
|
Independent PP film unwinding mechanism for double-sided lithium coating on copper foil strips.
PP film used as a protective layer between each layer during lamination.
|
|
Automatic Control System
|
Complete system for winding tension control.
Ensures product is not stretched during winding.
|
|
Unwinding Mechanisms
|
Active unwinding mechanism and automatic deviation correction system.
Deviation correction accuracy: ± 0.2mm.
|
|
Static Electricity Removal
|
Release film PET (PP) winding and unwinding mechanism equipped with static electricity removal device.
