摘要： Concave portions filled with particles of high-absorbent resin are arranged on an outer side surface of a cylinder part in a circumferential direction. When each concave portion passes an ejection start position lying posterior to the lowermost portion in a rotation direction, particles are ejected along a tangent line of the side surface at the ejection start position. A sheet conveying roller is located near the above lowermost portion. Annular grooves facing concave portions are formed on an outer side surface of the roller along a circumferential direction. The roller conveys a sheet member along its side surface so that the sheet member passes near the above lowermost portion. In the sheet member, groove portions corresponding to the annular grooves are formed. Since the tangent line intersects with the side surface of the roller, it is possible to eject particles into the groove portions and reduce scattering of particles.

摘要： In an absorbent sheet manufacturing apparatus, a first roller (31) and a third roller (51) are rotated while each first concave portion (312) faces a convex portion (512), and therefore sheet concave portion rows (913) are formed on a first sheet member (91). The first sheet member (91) is transferred from a first roller-outer side surface (311) to a cylinder-outer side surface (211) of a supply cylinder (21), and a lower portion of the cylinder-outer side surface (211) is in contact with the first sheet member (91) while supply concave portions (212) supplied with particles face the sheet concave portion rows (913). Therefore, particles can be supplied accurately into each sheet concave portion (912) included in the sheet concave portion rows (913) and be held in the sheet concave portion (912) while the particles are practically prevented from scattering to the outside of the sheet concave portion (912).

摘要： In an absorbent product (1), a first absorbent sheet (22) is disposed between a top sheet (21) and a back sheet (23). A second absorbent sheet (22a) is disposed between the first absorbent sheet (22) and the back sheet (23). The first absorbent sheet (22) includes a first upper sheet (221), a first highly absorbent material (222) in particulate or fibrous form, and a first lower sheet (223). The first absorbent sheet (22) extends in the longitudinal direction beyond the longitudinal edges of the second absorbent sheet (22a) on both longitudinal sides. On each longitudinal side, an extension (224) of the first absorbent sheet (22) beyond the second absorbent sheet (22a) includes a back-sheet contact region (225) that is spaced in the longitudinal direction from the longitudinal edge of the second absorbent sheet (22a) and that is in contact with the back sheet (23). This configuration suppresses the return of liquid.

摘要： Concave portions filled with particles of high-absorbent resin are arranged on a side surface of a cylinder part in its circumferential direction. When each concave portion passes about the lowermost portion, the particles are ejected. A first roller conveys a first sheet member so that the first sheet member passes near the above lowermost portion. A second roller is located anterior to the above lowermost portion with respect to a moving direction of the side surface of the cylinder part at the above lowermost portion, and conveys a second sheet member to the vicinity of the above lowermost portion, to place the second sheet member on the first sheet member which has been supplied with particles. In the second roller, annular grooves are formed on the side surface. Therefore, impact on particles which collide with the second sheet member on the second roller is absorbed and scattering of particles is reduced.

摘要： An absorbent sheet manufacturing apparatus has a cylinder part having a plurality of concave portions arranged in a circumferential direction, a particle filling part which is located above the cylinder part and which stores particles of high-absorbent resin, to sequentially fill the plurality of concave portions with particles by a particle filling opening in its lower end, and a communication part which is located adjacent to the particle filling opening. A concave portion facing a posterior edge of the particle filling opening is brought into communication with external space through the communication part. Therefore, when particles are filled into the concave portion from the particle filling part, air in the concave portion is forced out by particles entering the concave portion and is easily discharged to the external space through the communication part. As a result, it is possible to increase a density of particles filled in the concave portion.

Therefore, particles can be supplied accurately into each sheet concave portion (912) included in the sheet concave portion rows (913) and be held in the sheet concave portion (912) while the particles are practically prevented from scattering to the outside of the sheet concave portion (912).
