In this absorbent article manufacturing method, a textile material (31) is supplied in a scattered state to a rotating drum (2), the outer peripheral surface of which has accumulation recesses (22) formed therein, and the textile material (31) is deposited via suction into the accumulation recesses (22), thus producing an absorbent article (3) having a predetermined shape. The supply amount of the textile material (31) per unit time is periodically altered in accordance with the rotary movement cycle of the accumulation recesses (22), and as a result, obtained is the absorbent article (3) having portions where the basis weight of the textile material (31) is relatively high and other portions where such weight is relatively low.本發明之吸收體之製造方法係對於外周面形成有集聚用凹部(22)之轉筒(2)以飛散狀態供給纖維材料(31),藉由抽吸使該纖維材料(31)堆積於集聚用凹部(22)內而獲得特定形狀之吸收體(3)者,且藉由使纖維材料(3)之每單位時間之供給量配合集聚用凹部之旋轉移動週期而週期性地變化,而獲得具有纖維材料(31)之基重相對較高之部分與纖維材料之基重相對較低之部分之吸收體(3)。1‧‧‧吸收體之製造裝置2‧‧‧轉筒2f‧‧‧外周面3‧‧‧吸收體4‧‧‧管道5‧‧‧纖維材料供給部6‧‧‧脫模用鼓風裝置7‧‧‧真空輸送機7A‧‧‧帶式輸送機8‧‧‧供給量控制部9‧‧‧切斷裝置20‧‧‧筒本體20p‧‧‧分隔板21‧‧‧外周構件22‧‧‧集聚用凹部24‧‧‧按壓皮帶25‧‧‧輥26‧‧‧輥30‧‧‧吸收體30A‧‧‧吸收體連續體31‧‧‧纖維材料31A‧‧‧原料片材32‧‧‧吸水性聚合物35‧‧‧被覆片材36‧‧‧被覆片材51‧‧‧粉碎機52‧‧‧供給輥53‧‧‧驅動馬達55‧‧‧散佈管73‧‧‧通氣性皮帶74‧‧‧真空箱83‧‧‧旋轉編碼器91‧‧‧切刀輥92‧‧‧切斷刀93‧‧‧砧輥222‧‧‧中心軸部A‧‧‧空間B‧‧‧空間C‧‧‧空間D‧‧‧空間R‧‧‧旋轉方向
