How to Effectively Judge Press Felt Trials: Assessing and Improving Paper Machine Clothing Performance

摘要

Many papermakers have a love-hate relationship with their Paper Machine Clothing (PMC), and their press felts in particular. This paper aims to give you the insights you need as a pa-permaker to judge press felt trials effectively, so that you can increase the machines bottom-line through better performing felts. Press felts are probably the mechanical components that change the most over the course of their life in the machine, typically a number of weeks. By connecting output data of the machine with the life of each felt - and the changing felt properties per day — new insights are gained. These insights, presented as fact-based charts, give both the papermaker and the felt supplier an objective reference to judge the performance of trials, making the process to better press felts faster and more worthwhile.
