The present invention aims to provide a pull-on disposable wearing article having leg-openings of sufficient size and assuring that respective peripheries of the leg-openings reliably cover the wearers buttocks without apprehension that the peripheries of the leg-openings might collapse inward. A crotch panel (13) at least includes an absorbent structure (11) located on a skin-facing surface of a crotch region (16) and a pair of elastic side flaps (53) extending outward in a transverse direction (X) from both side edges of the absorbent structure (11). The elastic side flaps (53) have inelastic regions (57A) defined on the outer sides in the transverse direction (X) of both side edges of the absorbent structure (11) and elastic regions (57B) defined on the outer sides in the transverse direction (X) of the respective inelastic regions (57A). The crotch panel (13) has a dimension (W2) in the transverse direction (X) corresponding to about 55 to about 70% of a dimension (W1) in the transverse direction (X) of the front and rear waist regions (14, 15).

A device of extending a sheet-like member (15) having four corners (15c) across a pair of continuous sheets (20a, 24a) and bonding the sheet-like member (15) to the pair of continuous sheets (20a, 24a), the device including a holding member (51) that holds the sheet-like member (15) on a holding surface (51s) and circulates along a circulating trajectory, the holding member (51) and a roller member (82) arranged according to a predetermined position (Pout) cooperating to bond and deliver the sheet-like member (15) to the pair of continuous sheets (20a, 24a). The holding surface (51s) includes portions that respectively correspond to the four corners (15c) of the sheet-like member (15), each of the portions is a curve surface-like portion along an arc track that is drawn by the each of the portions when passing the predetermined position (Pout), and a track that is drawn when at least a part that is arranged between two adjacent curve surface-like portions in a direction along the circulating trajectory on the holding surface (51s) passes the predetermined position (Pout) is positioned more inwardly in the radial direction of the circulating trajectory than the arc track that is drawn when the two adjacent curve surface-like portions passes the predetermined position (Pout).

Provided is an excrement-treating material having a composite layer structure of a core part and a surface layer, in which the surface layer is bonded to the core part by utilizing the adhesion ability of a water-absorbable polymer in a compounding material for the surface layer without using an adhesive, and which suitably exerts the water absorbability and water transport ability that are inherent to the surface layer. The excrement-treating material is constituted by incorporating a pulverized water-absorbable polymer 7 that has been pulverized into particle sizes of from 20 m to 50 m, and adding water to the surface 1 a of the core part 1 after granulation to noncontinuously form a highly-wet part; reacting a water content in the highly-wet part and the pulverized water-absorbable polymer in the surface layer-compounding material to noncontinuously form an adhering part 8; bonding the surface layer 2 to the surface 1a of the core part through the adhering part 8; and upon absorption of excreted urine, accelerating the permeation of the excreted urine into the core part 1 in a part 9 other than the adhering part 8 between the surface layer 2 and the surface 1 a of the core part.

An ultrasonic welding apparatus performs ultrasonic welding to a sheet-like member associated with an absorbent article, the sheet-like member being transported while being wound onto an outer circumferential face of a rotating member, the rotating member rotating about its central axis. The apparatus includes: the rotating member; an ultrasonic processing unit that rotates about the central axis together with the rotating member, and that includes, as ultrasonic processing members, a horn that vibrates ultrasonically and an anvil that sandwiches the sheet-like member with the horn; and an ultrasonic-energy regulating unit. At least either one ultrasonic processing member of the horn and the anvil is guided so as to be able to reciprocate in a CD direction, the CD direction intersecting a transport direction of the sheet-like member, and the at least either one ultrasonic processing member of the horn and the anvil reciprocates in the CD direction with respect to a part of the sheet-like member, the part being wound around the rotating member. In the reciprocation, the at least either one ultrasonic processing member of the horn and the anvil moving to a crossed-over position that is located beyond an end part of the sheet-like member in the CD direction, and the horn and the anvil face each other at the crossed-over position. The outer circumferential face of the rotating member includes sections in which each end part of the sheet-like member is to be positioned. In the case where, of the sections, a section that the at least either one ultrasonic processing member of the horn and the anvil passes when starting to cross the sheet-like member in the CD direction being a first section, a section that the at least either one ultrasonic processing member of the horn and the anvil passes when finishing the crossing being a second section, the ultrasonic-energy regulating unit causes an amount (J/m) of ultrasonic energy to be applied per unit length in the CD direction to start decreasing, when the ultrasonic processing member is passing the second section.

The present invention aims to provide male absorbent pads improved so that the fit to the pads may be improved by partially convexing the article outward along a wearers body shape. A male absorbent pad has a longitudinal direction and a transverse direction being orthogonal to each other, a skin-facing surface and a non-skin-facing surface opposed to the former and a longitudinal axis P bisecting a dimension in the transverse direction, and including a liquid-permeable topsheet, a liquid-impermeable backsheet and a liquid-absorbent core interposed between the topsheet and the backsheet. The pad main body has flexion-inducing grooves recessing from the skin-facing surface toward the non-skin-facing surface. The flexion-inducing grooves have a first groove obliquely extending across the longitudinal axis and a second groove extending in a direction intersecting with the longitudinal axis and with the first groove; and an intersection point M of the first groove 41 and the second groove 42 lies on the longitudinal axis P.
