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 supports you in operating your 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.  

• Constantly monitor the wet line’s position in real-time from the operator station.
• Alarms if wet line is not at the right spot or spikes occur.
• Protect your critical wire section positions (turning, bonding points, etc.).
• Indication of actual wet line position and trend in any DCS. 
• Stabilized wet line position through IBS vacuum valves.
