摘要： An apparatus (1) for manufacturing an absorbent (A) for an absorbent article is provided with: a freely rotating suction drum (11), the circumferential surface (11S) of which is equipped with pattern plates (13) having a shape that is complementary to the outer shape of the absorbent and in which a pattern hole (13H) that passes through in the thickness direction is formed, and with molding portions (15), which are formed in the pattern holes of the pattern plates and are for forming absorbent by accumulating the material of the absorbent; and a supply device (21), which is provided with a cover duct (23) covering a portion of the circumferential surface of the suction drum and supplies the material for the absorbent to the molding portions through the cover duct. This apparatus is provided with an air-jetting mechanism comprising jetting ports (13O) and the jetting ports rotate with rotation of the suction drum and jet air from the pattern plates and/or the molding portions toward the internal space (S) of the cover duct.

摘要： This absorbent article improves absorption speed and liquid return suppression in a case where a bodily fluid is repeated absorbed. The absorbent article (1) is provided with an absorbent core (9) that includes highly absorbent polymer particles. The absorbent core comprises a first layer (6) on a non-skin-facing side and a second layer (8) on a skin-facing side. The first layer is provided with: a plurality of groove sections (18) that include a plurality of main groove sections (19) that extend in a longitudinal direction and penetrate in a thickness direction; and a plurality of base sections (20) that extend in the longitudinal direction. The main groove sections and the base sections extend in alternation in a transverse direction. The base sections each comprise a base section inner section (36) that is adjacent to the non-skin-facing side of the second layer and a base section outer section (34) that is adjacent to the non-skin-facing side of the base section inner section. The mean density of the highly absorbent polymer particles contained in the base section outer section is lower than the mean density of the highly absorbent polymer particles contained in the base section inner section.

摘要： A method for manufacturing an absorbent article in which, without stopping feeding of a first material (3ps) that has been continuously fed from a preceding first material coil (3p), a second material (3fs) supplied from a following second material coil (3f) is joined to the first material (3ps), then feeding the second material (3fs). The size of the first material coil (3p) in a diameter direction being larger than the size of the first material coil (3p) in a width direction, and the size of the second material coil (3f) in a diameter direction being larger than the size of the second material coil (3f) in a width direction. When attaching the first material coil (3p), the first material coil (3p) is attached while being sandwiched from two widthwise sides between a first positioning portion (25pa) and a first pressing plate (25pb). When attaching the second material coil (3f), the second material coil (3f) is attached while being sandwiched from two widthwise sides between a second positioning portion (25fa) and a second pressing plate (25fb).

摘要： A method for splicing a material associated with an absorbent article, including: transporting the material in a direction of transport with a material wound around an entrance roll (41u) and a moving roll (41m) of a dancer unit (40); splicing a subsequent material (3f) with a preceding material (3a) which is a material being transported, by bonding a leading end portion of the subsequent material with the preceding material; and cutting the preceding material so that the total length of a bonded portion (3j) and an stacking portion (3d) is larger than a path length of the material from a downstream end (P3) of a winding portion of the material that is wound around the entrance roll to an upstream end (P4) of another winding portion of the material that is wound around the moving roll positioned at a reference position.

摘要： The purpose of the present invention is to provide a method for manufacture of an absorbent article, with which it is possible to form a desired coloring pattern upon an absorbent article and to reliably manage the quality of said coloring pattern. Provided is a method for manufacture of an absorbent article, in which: microcapsules, which are provided upon a substrate and in which coloring agents are enclosed, are destroyed in a prescribed pattern, and the coloring agents discharged upon the substrate; and the substrate is coated with a developer, causing the coloring to be expressed in the prescribed pattern via a reaction between the coloring agents and the developer.
