An apparatus for manufacturing an absorbent core for disposable wearable articles by combining a first core portion and second core portions, the apparatus comprising: a feeder having a defibrator configured to generate fibers crushed into a fibrous form and feed the fibers; a first drum having a first area for sucking and stacking the fibers on an outer peripheral portion of the first drum, the first drum being configured to stack a first core portion in the first area; a second drum having a plurality of second areas, smaller than the first area, for sucking and stacking the fibers on an outer peripheral portion of the second drum, the second drum being configured to successively transfer second core portions stacked in each of the second areas to the first drum; and a variable speed drive configured to rotate the second drum at a high first circumferential velocity when the second drum transfers each of the second core portions and, rotate the second drum at a second circumferential velocity, lower than the first circumferential velocity, in non-transfer time, which is after the transfer and until subsequent transfer.
