Benefits and Advantages of Automated Paper Testing, 2006 Papermaker’s Conference

If the quality data coming from the paper-testing lab is not made available to paper machine operators in a timely manner, then this information can be used for quality verification and not as a tool for short-term process improvement. In the past, the Testing Department’s role would have been to provide end-user ‘proof’ of quality and to determine whether the paper would meet the quality specifications for that particular grade, thus allowing a “GO” or “NO GO” decision to be made. Invariably, re-testing would be required if erroneous or inconclusive information were forthcoming. This could mean delays in shipping to customers, rolls being culled or down graded, and lost production time.

To overcome this problem the paper-testing laboratory has now been automated thus becoming an essential production tool for the papermaker. And since the paper-machine is working 24 hours a day, 365 days a year, these automated paper-testing devices have to meet the same requirements and now play a key role in process control. They have also been proven to save money through manpower optimisation, increased production, and lower operating costs.

Reducing measurement uncertainty or test variability is at the heart of what an automated paper testing system provides the modern paper mill. In today’s competitive market place, costs have been cut to the bone. The largest potential for cost savings now comes from incremental changes in the paper making process. To achieve these cost savings accurate and frequent measurements of the product are required. The only way to achieve this level of reliability, consistency and accuracy is through the use of automated paper testing systems.
