Abstract
An apparatus for manufacturing an absorbent core includes: a dispenser for dispensing a fiber; a fiber-stacking drum for stacking the dispensed fiber on the outer circumferential surface while sucking the fiber toward an inside; and a fixed frame for rotatably supporting the fiber-stacking drum. The fiber-stacking drum includes: a rotation shaft; a wheel attached to the distal end of the rotation shaft; and a fiber-stacking ring provided on an outer circumference portion of the wheel for stacking the fiber A suction chamber is fixed to the fixed frame The suction chamber is arranged on an inner side of the fiber-stacking ring and produces a suction force toward an inner circumference of the fiber-stacking ring. The fiber-stacking drum is supported by the fixed frame so as to be slidable in an axial direction of the rotation shaft; and the wheel is removably attached to the distal end of the rotation shaft via a fastener.
