Abstract
This invention relates to an improved air acceleration nozzle for use in airlay web formers which reduce the creation of large scale vortices and turbulence. The nozzle accelerates the air by reducing the cross sectional area of the conduit. The size of the conduit for the air is reduced in both lateral dimensions, and more preferably, both dimensions are reduced with smoothly curving, low angle peripheral walls.
