VIB CurlTech

On-line Curl Control

Primary material for VIB CurlTech 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 VIB Control StationIPS.

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 Paper Industry

  • Increased sheet flatness for higher quality grades.
  • Flatter profiles and curl control can be achieved simultaneously.
  • Control curl to both sides by using VIB CurlTech on top and underside (plus/minus).
  • Narrow spacing of the actuator can be defined based on sheet flatness.
  • Optional feedback of the actuator position ensures reliable functioning of the VIB CurlTech Actuator.
  • Better edge performance for improved converting.
  • Curl control on siliconized surface.
  • Curl control on Coated Paper.
  • Curl control on converting machines.
  • 3 - 4% increase in efficiency of the total production line with integrated curl control.
