The position of the paper on the roll is measured with sensors and constantly controlled by the Exlar Tritex servo actutator. The Tritex actuator is equipped with an integrated controller with an analog input to which the signal from the sensor is connected. With the standard process control application in the software, the Tritex system is very easy to set up.
In spite of the constant control at 24-hour operation, the service life of the actuator is ensured by the roller-screw spindle in the Exlar actuator.
A belt sander is used for the production of 'High Voltage Cables'. In the belt sander the insulating sheaths of high-voltage cables with a diameter of Ø20 to Ø55mm are highlighted. The sanders and the main shaft rotate while the cable is being fed. The Exlar servo actuator with Bönnekamp rod head ensures the linear displacement in which the control unit is integrated on the Exlar servo actuator.
