Unwinding and rewinding are controlled by magnetic powder brake and magnetic power clutch. The drying system is of separate 3 sections at constant temperature and secondary drafting, resulting in energy saving and perfect drying. The first base-material unwinding adopts automatic deviation rectification to ensure side and correct gluing. The binding compression roller and gluing compression roller are pneumatically activated to ensure even pressure. The main motor adpots frequency-changing speed regulation, with stable running and energy saving. Large-size cast iron base-plate is used to guarantee preciseness of the whole machine and easy installation.
