Increasing Paper Machine Agility with a Novel Grade Change Concept
* To view the presentation controls tool bar, please place your mouse over the presentation
Description - A narrow grade mix and long grade runs were once common. Not today. Most machines make a wider set of products with many grade changes. A new grade transition concept makes such machines more competitive by increasing the stability and agility of the line. Unlike traditional programs, the new grade change concept relies on the normal quality controls to move the machine from one grade to the next quickly and smoothly in closed loop. Mill results are presented to demonstrate the effectiveness of the new approach.
