Unwind and rewind guiding
At the unwind, the roll itself is moved. The actuator shifts the whole unwind stand so the web edge enters the machine on line. At the rewind, it shifts the winding stand so the roll is wound with straight edges.
- Actuator travel
- ±25 to ±130 mm
- Thrust
- 2500 N
- Control accuracy
- 0.1 mm
- Response time
- 2 ms
One kit, four parts
Mounted on your existing unwind or rewind stand. The stand needs to be able to move sideways, usually on linear guides.
Touch-screen controller
Shows web deviation, actuator position, current and temperature.
Brushless actuator
2500 N, electronic brake, built-in position feedback.
Sensor and bracket
Ultrasonic sensor on a fine-adjustment bracket with 15 mm travel.
Standard supply: controller, actuator, sensor, adjusting bracket, cables and operation manual. A 24 V DC switching power supply and remote I/O cables are optional.
Choose by correction travel
Pick the travel that covers the worst lateral run-out of your rolls, with margin.
