ABSTRACT:
The present invention provides a method and apparatus for forming a pulsed stream of discrete particles of absorbent material. The apparatus comprises a particle metering apparatus for providing a stream of particles having a predetermined mass flow rate, an ejector having an acceleration air nozzle for accelerating the stream of particles, at least one deceleration air nozzle; and valving for alternately directing air through the acceleration and deceleration nozzles. The apparatus can be used to form a fibrous web having a predetermined variation in basis weight of absorbent material along the length of the web.
