absorption materials” (specification, page 1). Representative
claims 1, 2, and 9 read as follows:
1. An absorbent structure suitable for use in an absorbent
article, comprising:
first, second, and third superposed strips of at least one
web-shaped absorption material, said first, second, and third
strips being dimensioned and arranged so that a perimeter of the
first strip lies entirely inside of a perimeter of the second
strip, and a perimeter of the second strip lying entirely inside
a perimeter of the third strip;
the absorbent structure (4) comprised of said strips having
been compressed to a thickness which is substantially the same
over the structure, so that the structure has a higher density in
the area thereof where the strips overlap each other and a lower
density in other areas.
2. An absorbent structure suitable for use in an absorbent
article, comprising:
a sheet of web-shaped absorption material (5) which has been
folded back and forth upon itself to produce a plurality of
effective layers arranged so that a number of the effective
layers in a center of the absorbent structure is greater than a
number of the effective layers in a peripheral area on each side
of the center area, and the folded sheet having been compressed
to a thickness which is substantially the same over the
structure, so that in cross-section the structure has a higher
density in the center area where the effective layers overlap
each other and a lower density in the peripheral areas.
9. A method for making an absorbent structure in an
absorbent article, comprising the steps of:
placing first, second, and third strips of at least one web-
shaped absorption material superposed with each other, said
first, second, and third strips being dimensioned and arranged so
that a perimeter of the first strip lies entirely inside of a
perimeter of the second strip, and a perimeter of the second
strip lying entirely inside a perimeter of the third strip; and
compressing said strips to form the structure having a
thickness which is substantially the same over the structure, so
that the structure will obtain a higher density in the area
thereof where the strips overlap each other and a lower density
in other areas.
