6. The intermediate tension of coating roller and traction steel roller is synchronous, which is controlled by PLC automatically.
7.Automatic meter and speed control device.
8. EPC gas sensitive edge aligning machine is adopted for deviation correction, so as to make the material winding more orderly.9.Key type air expansion shat is adopted for retraction and release, which is convenient and fast for loading and unloading.10. High precision up pressure type traction device, steel roler cooling adopts water circulation type, through the cooling roller, the film is smootherand the cooling effect is better achieved
