PROBLEM TO BE SOLVED: To provide a device and a method for manufacturing an absorber, allowing high-accuracy adjustment of basis weight of each part of the absorber.SOLUTION: This device for manufacturing an absorber includes: a duct 4 supplying absorber raw material in a state that the absorber raw material is on an air flow and a suction/accumulation part 22 sucking and accumulating the absorbent raw material. The device for manufacturing the absorber has accumulated the absorber raw material on the suction/accumulation part 22 while advancing the suction/accumulation part 22 to one direction, and thereafter releases the deposit from the suction/accumulation part 22. The suction/accumulation part 22 is divided into a plurality of recessed parts 221-227 including a suction part made of a porous material in bottom parts, and has high basis weight accumulation regions, in each of which the absorber raw material is accumulated to high basis weight, and low basis weight accumulation regions, in each of which the absorber raw material is accumulated to lower basis weight than the high basis weight accumulation regions. In the recessed parts 221, 222, 224-227 positioned in the low basis weight accumulation regions, the ratio of the area of the suction part to the area of opening parts is smaller than the ratio of the area of the suction part 223e to the area of the opening parts 223d of the recessed parts positioned in the high basis weight accumulation regions 223.COPYRIGHT: (C)2012,JPO&INPIT【課題】吸収体各部の坪量を精度良く調整可能な吸収体の製造装置及び製造方法を提供する。【解決手段】吸収体原料を空気流に載せて供給するダクト4と、該吸収体原料を吸引して堆積させる吸引堆積部22とを備え、吸引堆積部22を一方向に進行させつつ吸引堆積部22に吸収体原料を堆積させた後、吸引堆積部22から堆積物を離型させるようになされている吸収体の製造装置であり、吸引堆積部22は、底部に多孔性材料からなる吸引部を備えた複数の凹部221~227に区画されると共に、吸収体原料を高坪量に堆積させる高坪量堆積領域と、吸収体原料を高坪量堆積領域に比して低坪量に堆積させる低坪量堆積領域とを有し、低坪量堆積領域に位置する凹部221、222、224~227は、開口部の面積に対する吸引部の面積の比率が、高坪量堆積領域223に位置する凹部の開口部223dの面積に対する吸引部223eの面積の比率より小さくなされている【選択図】図4
