  • Method and apparatus for creating a pulsed stream of particles
    Publication number: 20060264134
    Abstract: The present invention is a method of and an apparatus for creating a pulsed stream of particles in a carrier means, such as air. A pre-metered stream of particles is accumulated in a pulsing chamber of a pulsing means by interrupting the stream of particles by a separator means, which interrupts the flow for a certain portion of the pulse period. The accumulated particles are then removed from the pulsing means by suction, such as by using an ejector. The invention is further directed to a kit or pack of individual absorbent articles which can be produced using the method and the apparatus.
