Feedback tension unit

To maintain the stability of the winding tension value, can feedback tension bar angle position information, has line speed dynamic control of the structure of the tension control device.
According to the start and end inertia, and boobins shape, can reduce tension values change, prevent wire broken, and keep stable winding.
The control mode have Electronic type, pulse motor type, servo motor type.
Besides, according to different models, can switch back tension's ON and oFF (back-tension ON and OFF function), by winding program, can change any tension values (with tension control function), The company all automatic winding machine can be configured.
