Advanced wire part simulation with a moving belt former and its applicability in scale up on rotogravure printing paper

摘要

Formation, drainage and retention are important parameters when evaluating wet end operations during papermaking. Improving one of these parameters often means deteriorating another. This paper will describe a new tool for simulating the wire section of a paper machine. The Moving Belt Former (MBF) has been developed for simulating the pulsating dewatering on the wire section of a paper machine. In a scale-up, the MBF has been shown to give reliable results when investigating retention chemicals and their effect on paper machine performance.
