LineVision^®

Continuous dewatering along the forming table of Fourdrinier machines creates a line where the transition of the stock suspension from wet to dry can be observed: the so-called wet line. LineVision® gives you the tools to operate a machine with the wet line at the right spot! This is essential to achieve the highest paper quality and runnability.  If the wet line reaches the combining roll, where two plies meet, it can adversely affect paper quality (bonding of the plies strength, etc.). On the other hand, running the wet line too close to the headbox will reduce paper quality due to the reduced sheet forming area.  

• Continuous live monitoring of wet line position remotely from operator station. 
• Indication of actual wet line position and trend in any DCS. 
• Stable wet line position through closed loop control with IBS vacuum control valves. 
• Smart alarms if wet line is not at the right spot or spikes occur. 
• Automatic control for process parameters to achieve optimum wet line position.
