Abstract
An apparatus for transferring a fast-running, ready-dried fibrous web from a first location to another with minimal undesirable motion is described. The apparatus includes an air foil defining a web support surface which extends substantially continuously from a first processing location to a second processing location, and includes at least two air supply channels extending substantially perpendicular to the direction of web travel across the air foil for providing flows of pressurized air between the foil and the web being, processed in the general direction of web travel. In this way, a layer of reduced static pressure is provided which stabilizes the web against undesirable motion, while the build up of dust is minimized.
