대표청구항 ▼

The invention claimed is: 1. A method of producing an absorbent article, the method comprising: 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 through a pulsing chamber in the pulsing step at a frequency of at least 5 Hz by using a rotating separator means to form a pulsed particle stream; and transferring a pulse from the pulsed particle stream onto a forming surface of the absorbent article. 2. The method of claim 1, wherein the metering includes metering the particles at a predetermined constant mass flow rate to form the metered particle stream. 3. The method of claim 1, wherein the carrying includes carrying the metered particle stream in a carrier flow created by a downstream suction to form the carried particle stream. 4. The method of claim 1, wherein the pulsing includes, for each pulse: interrupting the carried particle stream; and discontinuing the interrupting. 5. The method of claim 1, wherein the pulsing includes, or each pulse: accumulating a portion of the carried particle stream, to form an accumulation of particles; and releasing at least a portion of the accumulation of particles, to form at least a portion of each pulse. 6. The method of claim 1, wherein the pulsing includes forming a pulsed particle stream with substantially rectangular-shaped pulses. 7. The method of claim 1, wherein the transferring includes accelerating the pulse from the pulsed particle stream in an eductor carrier flow. 8. The method of claim 1, wherein the transferring includes forming a substantially uniformly distributed pulse profile on the forming surface of the absorbent article.
