The BelLiner is a twin wire former used to produce one or more of the individual plies of a multiple-ply sheet. This technically advanced twin wire, top former can be used on both light and heavy weight board grades. It enables boardmakers to respond to today’s higher quality requirements, while maintaining or increasing productivity. The two distinct applications are 1) top ply former and 2) middle ply former. More than one BelLiner can be put on a paper machine. This paper focuses on the top ply former application and more exclusively as a top ply former for whitetop linerboard. The former development history, the former’s operating principals and configuration and two case studies of operating BelLiners will be discussed.
