Abstract
This invention relates to improved aerodynamics in dry fiber web forming machines and particularly to airlays which form high quality webs. The invention includes a disperser roll for feeding fibers into the air stream and a second roll opposite to the disperser roll for balancing the disruptive effects of long stationary walls and rotating members in the air duct. In one alternative arrangement of the invention, the fibers are also fed to the air stream by a second disperser roll opposite the first disperser roll.
