1. A method for making a structure that comprises particulate material supported or enclosed by a substrate material, including the steps of:

  • a) feeding a first particulate material with a feeder to a first moving endless surface with a plurality of reservoirs, adjacent said feeder;

    b) allowing flow of said particulate material, or part thereof, into a volume space present between said first moving endless surface and a three-dimensional plate, adjacent said feeder and adjacent and opposing said first moving endless surface; and

    contacting a part of said particulate material with said three dimensional plate, said plate having a first plate face adjacent said first moving endless surface, and said plate face having;

    i) a first surface area substantially parallel to said first moving endless surface; and

    ii) a second surface area neighboring said first surface area, being downstream (in MD) from said first surface area, said second surface area being non-parallel to said first moving endless surface and leading from said first surface area towards said first moving endless surface, said first surface area and said second surface area are connected to one another under an angle, and said second surface area having an average angle with said first moving endless surface from about 10°

    to about 80°

    ;

    c) applying a pressure with said plate onto at least a portion of said particulate material present between said first plate face and said first moving endless surface, guiding said material into said reservoirs;

    d) transferring said particulate material in said reservoirs of said first moving endless surface directly or indirectly to a second moving endless surface, being, or carrying, said substrate material; and

    e) depositing said particulate material onto said substrate material.
