Absorbent core for disposable absorbent article

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.

Apparatus and process for transferring substrate material and particulate material

An apparatus for making a structure comprising solid material and typically a substrate, said apparatus comprising a first moving endless surface and adjacent thereto one or more stationary primary (vacuum) gas containers (chambers), at least one thereof being connected to a secondary (vacuum) gas container, whereby the pressure difference between primary and secondary containers is minimized; and methods using such an apparatus.
