Abstract
A papermaking machine air foil including a housing having a top surface, a bottom surface, side surfaces, a leading edge and a trailing edge, at least one air inlet on the top surface that directs injected air into the housing, and an air slot formed in the bottom surface that directs ejected air from the housing towards a trailing edge of the air foil, the air slot having a V-shape. The papermaking machine air foil is configured to be disposed on top of a paper web at a position adjacent to a Yankee dryer so that the ejected air directed by the air slot of the air foil stabilizes the paper web as the paper web is removed from the Yankee dryer.
