Apparatus and method for transferring particulate material
First Claim
1. An apparatus for making a structure that comprises particulate material supported or enclosed by a substrate material, the apparatus comprising:
- a first endless surface comprising a reservoir and adapted to move in a direction of movement;
a particulate material feeder positioned adjacent the first endless surface and adapted to deposit particulate material to the reservoir;
a second endless surface positioned adjacent the first endless surface and adapted to receive particulate material from the reservoir;
a three-dimensional plate positioned adjacent the particulate material feeder and adjacent the first endless surface, the three-dimensional plate adapted to guide particulate material into the reservoir and to apply pressure on the particulate material, the three-dimensional plate comprising a plate face comprising a first surface area connected with a second surface area; and
wherein the first surface area is substantially parallel to the first endless surface, wherein the second surface area is positioned downstream in the direction of movement from the first surface area, wherein the second surface area defines an angle from about 10°
to about 80°
with respect to the first endless surface.

Abstract
An apparatus for transferring, at high speed and in a very effective and accurate manner, particulate material from a feeder into reservoirs of a moving endless surface, e.g. a drum, by use of a pressure means, e.g. a specific three-dimensional plate, for applying pressure onto said particulate material present between said plate and said moving endless surface, and then transferring the particulate material with said moving endless surface with reservoirs to a substrate; the apparatus and method being particularly useful for the production of absorbent structures for absorbent articles.
