POSITIVE PULSE DEWATERING BLADE

摘要

A blade (22) for the removal of water from a sheet of material in paper- making has a leading edge (48) shaped to direct water on the underside of the wet web toward the web. This action loosens the web and facilitates further removal of water therefrom. The blade has a trailing edge portion (56) spaced from the next successive blade to provide a drainage opening for a liquid removed from the wet web as it completes passage over the wear surface of the blade.
