Primary material for CurlTek is 1.4571 (316 Ti) stainless steel. A special steam heating system of diffuser plate and dwell zone assures complete heating even during longer sheetbreaks.
Control StationECS is an electronic control station that governs the pneumatic actuators. Each actuator is controlled by an I/P-converter with a control signal of 0.8 - 4 bar (12 - 60 psi). Setpoints are sent from the control station.
Control StationIPS is an integrated process station that serves as the central process point for the system. It contains the integrated control, the operator visualization package, PLC functions and the intelligence to control the entire actuator control system.

Benefits for the Converting Industry
- Increased moisture and sheet flatness for higher quality grades
- Flatter profiles and curl control can be achieved simultaneously.
- Control curl to both sides by using CurlTek on top and underside (plus/minus).
- Narrow spacing of the actuator can be defined based on sheet flatness.
- Better edge performance.
- Curl control on siliconized surface.
- Curl control on coated paper.
- Curl control on converting machines.
- Increase in the efficiency of the total production line with integrated curl control.
