Abstract
An apparatus and method for effecting zoned deposition of superabsorbent particles in a fibrous web includes the use of dual dispensing nozzles for forming selected deposition patterns. Fluidized streams of the superabsorbent particles are formed, with rotary valve assemblies employed for creating pulsed flow to each of the dispensing nozzles. The length, width, and relative positioning of the deposition patterns can be selectively varied in accordance with desired performance characteristics.
