| List of control equipment Configuration element (In case of spreading brake) | Features, Application | Control equipment, tool 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. | PCF type automatic equipment RD type detector TA type tension display
* 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. | PCD type automatic controller
* 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. | PCA type automatic controller 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. | PCT type automatic controller SEP type detector PS type power amp
* Electromagnetic powder clutch/brake * Hysteresis clutch/brake * AC servo motor |
| Manual control method | ||
|
| * Wide range torque control. * Can be used with simple rollers and unwinders. * Simple handling and operation. | PCM controller PS type controller(6.0A) PS type controller(2.8A)
* Electromagnetic powder clutch/brake * Hysteresis clutch/brake * Tension brake |
