HIGH VACUUM SHEET DEWATERING

• This TIP outlines procedures for determining the water removal performance of the flat box section of sheet formers.
• The objective of the TIP is to provide a high-resolution method to maximize dewatering and minimize frictional drag load, fabric wear, airflow and vacuum requirements, and required on-machine hardware.
• The method described is based on empirical work on a pilot machine, verified on many commercial paper machines. Data was acquired on the pilot machine and regression analysis was used to reduce the data to an easily usable form.
