Patent ID: 7297307

Claim:
A method of producing an absorbent member comprising feeding a superabsorbent polymer and pulp fiber both in the form of a dispersion in an air stream, depositing the superabsorbent polymer and the pulp fiber in a flat bottom recess by suction through a plurality of suction holes provided in the bottom of the recess, and releasing the deposited aggregate from the recess, wherein the flat bottom of the recess has a first suction region ( 51 ) having an open area ratio R 1 of 40 to 80% and a second suction region ( 52 ) having an open area ratio R 2 of 2 to 20% with the ratio of R 1 to R 2 ranging from 70/30 to 99/1, the superabsorbent polymer and the pulp fiber are deposited on both the first and the second suction regions, wherein a difference in open area ratio R between the first and the second suction regions ( 51 ) and ( 52 ) is made by forming suction holes at pitches different between the two regions and wherein the suction holes have an average diameter of 0.05 to 0.5 mm in each of the first and second suction regions.
