    Abstract: An apparatus for transferring, at high speed and in a very effective and accurate and cost effective manner, particulate material from a first moving endless surface with reservoir(s) to a second moving endless surface carrying a substrate material, such as a nonwoven web material, and transferring said combination of substrate material with particulate material to a further apparatus unit; said second moving endless surface is adjacent and in communication with a first and a second vacuum chamber, with different vacuum pressures and/or different size. Also a process is provided, using the described apparatus.

    Abstract: A method and apparatus for forming a batt of particulate material which may be used in an absorbent article. The apparatus may include a vacuum zone, an air impermeable fence zone adjacent to the vacuum zone, and an air permeable fence zone adjacent to the vacuum zone. The air permeable fence zone may comprise an ambient air entry conduit in communication with an ambient air exit port. The method may include providing a laydown drum and a first web of material, positioning the first web of material substantially adjacent to the laydown drum, generating a vacuum through the laydown drum, depositing particulate matter onto the first web of material, and rotating the laydown drum.
