Effective and reliable operation of the paper machine can be extremely challenging.

The paper machine is the final stage in the pulp and paper process for producing paper products.

Most modern paper machines are based on Fourdrinier machine principles, which utilizes a moving woven mesh to create a continuous paper web by filtering out excess water from the paper stock for further processing.

There are many potential sources for process variability can can result in off-spec product or a sheet break and lost production.

As paper stock leaves the stock preparation area, it passes through the headbox of the paper machine to assure uniform distribution of stock flow across the forming screen before the filtration process begins. Next, the paper stock passes through a series of foils, various types of rolls, suction boxes, and other parts in the forming section to filter excess water to form the sheet of fiber. The wet fiber web then passes through the press section to squeeze out as much water as possible before passing through the heated drying section. From the dryer, the paper sheet passes through the calender section for smoothing, then finally onto the reel where the paper is wound onto individual spools for further processing.

Effective and reliable operation of paper machines can be extremely difficult as there are many critical loops in each section of the process that require highly accurate and reliable continuous measurement and control. Variability in basis weight, moisture content, stock flow, headbox level, and vacuum and dryer temperature can all result in off-spec product, or a sheet break and lost production.

Choose best-in-class measurement and controls technology to reduce process variability and increase reliability.

Control Associates and its instrumentation division Pro-Tech Solutions provide precision performance Fisher™ control valves, Rosemount™ measurement instrumentation, and advanced DeltaV™ distributed control systems uniquely engineered for optimizing the control and reliability of paper machines. Specialized basis weight control valves, high performance butterfly valves for vacuum control, high signal and thick stock magnetic flow meters, and advanced machine control solutions all contribute to the effective and reliable operation of paper machines.
