Abstract: A manufacturing device includes a guiding part that guides an elastic member between a pair of sheets conveyed by a pair of nip rolls; a moving mechanism that reciprocates the guiding part along a moving path; and a reciprocation control part. The moving mechanism has a first rotation member that is rotatable about a first rotation center shaft and capable of changing a first rotation radius connecting the guiding part and the first rotation center shaft to each other, and a second rotation member that is rotatable about a second rotation center shaft, connected to the first rotation member so as to be rotatable each other, and capable of changing a second rotation radius connecting the guiding part and the second rotation center shaft to each other. The reciprocation control part synchronizes rotation of the first rotation member and rotation of the second rotation member with each other.

Abstract: The liquid permeability and liquid diffusion of absorbent body is enhanced. (i) A belt-like main sheet formed of a non-woven fabric sheet constituting at least part of a first main surface is conveyed in a longitudinal direction of the main sheet; (ii) a slit is formed in the non-woven fabric sheet at a first position on a conveying path; (iii) at a second position, particulate matter absorbing and retaining liquid is dispersed into the first main surface, in such a way that the particulate matter is held in the non-woven fabric sheet; and (iv) at a third position, a covering sheet which prevents passage of the particulate matter is overlaid on the first main surface. At the second position, the non-woven fabric sheet includes a bulky structure which constitutes at least part of the first main surface and which has voids allowing the particulate matter to enter.

Abstract: A sheet conveyance device for conveying, along a conveyance path, a sheet in which a given region from an obverse surface toward a reverse side thereof is composed of a non-woven fabric, and a powder supply device for supplying a powder to at least a partial zone of the sheet, are provided. Further, a fiber-raising device for raising fibers in at least part of the powder supply zone of the sheet is provided on the conveyance path at a position upstream of the powder supply device in a conveyance direction of the sheet.

Abstract: A transport device includes a plurality of pads that hold and transport a workpiece while a peripheral speed is changed. The transport device further includes: a rotation shaft having an axial line serving as a rotation center; a rotation body that rotates around the rotation shaft; the plurality of pads that hold and transport the workpiece while the peripheral speed is changed with respect to the rotation shaft; transmission mechanisms that change a speed of each pad; and a motor provided for each pad and including an output shaft that drives each of the transmission mechanisms. In the transport device, each motor is attached to the rotation body, and is arranged around the axial line of the rotation shaft such that the output shafts are parallel to each other in a direction in which the axial line of the rotation shaft extends.

Abstract: A layered body containing continuous sheets is thermally fused when passing through a space between an anvil roll and an energy applying device to form a layered sheet. A nip stage for sandwiching the layered body is provided upstream of the space between the anvil roll and the energy applying device. The nip stage includes at least one displacement member which is displaced in accordance with the thickness of the layered body sandwiched by the nip stage. Whether the thickness of the layered body sandwiched by the nip stage has deviated from a reference range is detected on the basis of the displacement of the displacement member, and when it is detected that the thickness has deviated from the reference range, the energy applying device is caused to retreat in a direction going away from the anvil roll.

Abstract: An elastic resin material having a thermoplastic elastic resin as a main component is heated and melted, and the elastic resin material is discharged in a film or a linear shape from a discharge mechanism to form a film-shape or a linear-shape intermediate product. At a temperature above the temperature region at which the elastic resin material elastically deforms, extending is performed until the thickness or width of the film-shape intermediate product or the thickness of the linear-shape intermediate product assumes a prescribed value; with a cooling roller, the intermediate product is cooled to the temperature region at which the elastic resin material elastically deforms, and the intermediate product is hardened, forming a film-shape or linear-shape elastic member. The elastic member is stretched with a stretch roller to a prescribed stretching ratio, and the stretched elastic member is laminated on and bonded to a first base material sheet.
