Applied actuator
Feedback control method Micro deviation Automatic control

High precision, fully automatic tension control using an automatic closed loop control.

 Can maintain a continuous tension value.

 By using a micro deviation detector, there is no delay in mechanical response.

●Electromagnetic powder clutch/brake

●Hysteresis clutch/brake

●AC servo motor

Dancer roller automatic control

High precision, fully automatic tension control using an automatic closed loop control.

Wide range torque control.

Able to be installed on a wide range of machinery.

SNW type automatic controller
SEP type detector

●Electromagnetic powder clutch/brake

●Hysteresis clutch/brake

●Tension brake

Open loop control method Roll diameter proportional type automatic control

Achieves a precise tension control by coupling the brake current to be proportional to the roll diameter.

By using a non-contact detection unit, this unit is easily installable on a wide range of machines.

●Electromagnetic powder clutch/brake

●Hysteresis clutch/brake

●AC servo motor

Roll diameter detection type automatic control

By using twin detectors, the roll diameter can be identified and controlled with great precision.

Pulse encoder

●Electromagnetic powder clutch/brake

●Hysteresis clutch/brake

●AC servo motor

Touch roll type automatic control

Achieves a precise tension control by coupling the brake current to be proportional to the roll diameter.

Since the material is detected directly, we can achieve high-precision tension control.
