METHOD AND APPARATUS FOR PARTICULATE REMOVAL FROM MOVING PAPER WEBS

A method for removing dust-carrying air from a moving paper web is disclosed. The method includes the steps of: providing a moving web, the web having a first side and a second side, the web moving at a sufficient rate to produce a boundary layer of adjacent dust-carrying air; providing a NACA duct,...

Zusammenfassung:	A method for removing dust-carrying air from a moving paper web is disclosed. The method includes the steps of: providing a moving web, the web having a first side and a second side, the web moving at a sufficient rate to produce a boundary layer of adjacent dust-carrying air; providing a NACA duct, the NACA duct having an intake opening and walls that diverge in increasing cross-sectional area to an exhaust opening having greater cross sectional area than the intake opening; and submerging the intake opening into the boundary layer to scavenge dust-carrying air from the boundary layer.
