Servo tensioner is sent from the traditional passive-line change to take the initiative to send lines from the motor, by replacing the spring tension to change its value, this product comes with tension feedback stabilization system that can automatically tension stable equilibrium. Tension is not speed, wire cover, pulleys, and felt the impact of tension in particular stable and easy to adjust.

SETC-BR series with cylinder and the tension pulley is under of front servo tensioner, which the cylinder is mounted inside the enclosure, it have attenuation function, when not turned on the pressure, the tension can be adjusted by the knob and swing arm under the knob to control the tension.  when a certain period in the winding, thread and other processes require larger back tension , the pressure can he turned on.  When the winding machine through a solenoid valve to control the switching valve, the swinging stopper will happen a certain angle in order to get two tension values and avoid disconnection. These series model and configuration pls see the sheet on the right, the user can select the appropriate model based on the diameter and tension range.
