The pilot paper machine at Western Michigan University was modified to eliminate drainage at the forming board. This was achieved by inserting a thin plate under the wire, from the breast roll beyond the point of jet impingement. Two different plates were used - one five inches and one ten inches. Data was collected to determine the effects the modifications had on the table's performance and web formation and retention. The following can be concluded from this study: the modifications increased the web's consistency leaving the couch, yielded poorer formation, and had insignificant affects on solids retention. Problems occurred when obtaining samples from the table. This led to some uncertainty to the data.
