<p>A system for dispersing and transporting particulate matter to a forming bell which spreads same laterally on a moving receiving surface to form a nonwoven web. A more uniform web is formed by the system by loading the forming bell more symmetrically. The system includes a fluidizing chamber (36) and a conduit (42) for introducing particulate matter into the chamber and directing it against fluid entering the chamber from another location (36). A Coanda nozzle (18) communicates with the chamber and entrains the particulate matter and fluid in the fluidizing chamber and transports same in a direction differing from the original direction of movement of the particulate matter and fluid. </p> |
