Abstract: A method of producing absorbent articles, comprising: suspending particles in a gas carrier to form suspended particles; creating a series of pulses from the suspended particles, wherein each pulse in the series of pulses is created by: accumulating at least some of the suspended particles in a pulsing chamber to form accumulated particles on a rotary separator, and releasing at least some of the accumulated particles by rotating the rotary separator to create each pulse; and suctioning each pulse from the series of pulses onto a forming surface for the absorbent articles.

Abstract: A method of producing an absorbent article, including: metering particles at a predetermined flow rate to form a metered particle stream; carrying the metered particle stream in a carrier flow to form a carried particle stream; pulsing the carried particle stream to form a pulsed particle stream; and transferring a pulse from the pulsed particle stream onto a forming surface of the absorbent article.

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.

Abstract: The invention is a method applying a foamable movement obstruction agent to an absorbent article which comprises superabsorbent material. The foamable agent can be applied before, after, or simultaneously to creation of the foam structure, and can be applied to the article directly or to a carrier substrate to then be combined with the article.
