Abstract: A manufacturing apparatus for an absorbent body including: a first conveyor that conveys an air-permeable first sheet while sucking the first sheet along a flat first slope surface; a second conveyor that conveys an air-permeable second sheet while sucking the second sheet along a flat second slope surface having a slope opposite to the first slope surface; a first distribution device that forms a first absorbent layer in the first sheet by distributing absorbent powder on an upper surface of the first sheet being conveyed along the first slope surface; a second distribution device that forms a second absorbent layer in the second sheet by distributing absorbent powder on an upper surface of the second sheet being conveyed along the second slope surface; and a stacking part that stacks the first sheet conveyed by the first conveyor and the second sheet conveyed by the second conveyor in such a manner as to cause the first absorbent layer of the first sheet and the second absorbent layer of the second sheet to face each other.

Abstract: A disposable wearable article includes an absorptive body in which an absorber is disposed between a top sheet and a back sheet; flap parts that are put on one of a front part and back part of the absorptive body and extend to the both sides in the around-torso direction; and fastener members that are each provided on the flap part at a distance from a tip end of the flap part in the around-torso direction and are attachably and detachably joined to an opposing part put on the absorptive main body. Each flap part is formed from thermoplastic nonwoven fabric and has, in an extending part between the tip end of the flap part and the fastener member, a thermally-fused part at which the nonwoven fabric is thermally fused and bending rigidity of the nonwoven fabric is increased.

Abstract: A method of manufacturing disposable wearable articles includes: a step of carrying in a continuous direction a first continuous web for forming pocket members; a step of forming a pocket web by placing a first elastic member in a stretched state on the first continuous web; a cutting step of successively cutting the pocket web to obtain pocket members with a predetermined length; an orientation changing step of changing the orientation of the pocket members by turning the pocket member so that a carrying direction of the pocket member aligns with a width direction of the pocket member; a repitch step of increasing a spacing between mutually adjacent pocket members; and a placement step of placing the pocket members across a pair of three-dimensional gathers, wherein the cutting step, the orientation changing step, and the placement step are performed on a suction drum.
