摘要： 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.

摘要： An apparatus for removing particulate-carrying air from a moving web. The moving web has a first side and a second side. The apparatus includes a NACA duct positioned in a non-contacting relationship on a first side of the moving web, and at least partially submerged in a particulate-carrying boundary layer of the moving web. The NACA duct can have an intake opening and an exhaust opening such that when the intake opening is submerged in the boundary layer at least a portion of the particulate-carrying air from the boundary layer enters the intake opening and exits the exhaust opening, thereby scavenging particulate-carrying air from said boundary layer.
