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.

Abstract: A method in which, while an article is carried with a main portion in contact with a carrying surface and a to-be-folded portion in contact with a folder plate, includes: a first guiding step, wherein a first guide surface guides the to-be-folded portion of the unfolded article, on a side of the carrying surface, in parallel to the carrying surface; a second guiding step, following the first guiding step, wherein a second guide surface, while being in contact with the to-be-folded portion, gradually raises the to-be-folded portion while moving downstream; and a third guiding step, following the second guiding step, wherein a third guide surface guides the to-be-folded portion so that the to-be-folded portion is folded onto the main portion.

Abstract: A sheet conveying device includes: a holding mechanism configured to hold suction members; and a driving device including a rotary shaft which is rotatable about a second axis parallel to the first axis and a connecting mechanism configured to connect the rotary shaft and suction members to each other; and a support mechanism configured to support the holding mechanism and the drive device. The connecting mechanism is connected to the suction members in a state where the suction members are movable in a radial direction of the circle about the first axis. The support mechanism supports the holding mechanism and the drive device such that the holding mechanism and the drive device are relatively movable from each other in a direction orthogonal to the first axis.

Abstract: In order to manufacture a wearable article of the first size, the introduction velocity is set to the first introduction velocity having a high velocity and the arrangement velocity is set to the first the arrangement velocity having a high velocity. In order to manufacture wearable article of the second size having a shorter length in the carrying direction than that of the first size, the introduction velocity is set to the second introduction velocity lower than the first introduction velocity and the arrangement velocity is set to the second arrangement velocity lower than the first the arrangement velocity and the drum velocity is set to a fixed velocity regardless of the size.

Abstract: An apparatus for manufacturing an article including an absorbent body includes: first and second rolls, in cooperation with each other, for trimming a continuous laminate to be the absorbent body so as to successively form the narrowed portions along the continuous laminate; a third roll for rotating in contact with the second roll to receive the continuous laminate from the second roll; and a separating cutter for successively severing the continuous laminate being carried by the third roll into units of individual articles, thereby obtaining the absorbent body.
