Abstract: The method of the present invention includes the steps of: arranging a plurality of non-continuous sheets of a predetermined length intermittently and successively in the conveyance direction on the continuous sheet so that the continuous elastic members are sandwiched between the non-continuous sheets and the continuous sheet; in an overlapping area where the non-continuous sheets overlap with the continuous sheet, attaching the continuous sheet and the non-continuous sheets to each other by welding the sheets to each other in a predetermined pattern, thus producing a continuous laminate; and in a non-overlapping area where the non-continuous sheets do not overlap with the continuous sheet, heating the continuous sheet in the same pattern as said pattern.

Abstract: Provided are a method of producing ear loop members for masks and a device for producing ear loop members for masks with which it is possible to inhibit a reduction in the production efficiency of the masks. The method of producing ear loop members (4) for masks includes a conveyance step (S2), a tension adjustment step (S3), and a forming step (S4). In the conveyance step (S2), a sheet (U1) having high stretchability in a high-stretch direction (DH) is conveyed in a conveyance direction (C10) running along the high-stretch direction (DH) while tension is applied in the high-stretch direction (DH) to the sheet (U1). In the tension adjustment step (S3), the tension in the conveyed sheet (U1) is adjusted. In the forming step (S4), ear loop members (4) are formed by cutting the sheet (U1) after the tension adjustment.

Abstract: Provided is a method for manufacturing absorbent articles that readily suppresses an area in which a manufacturing device is installed. The method for manufacturing absorbent articles includes a conveying step (S1), a moving step (S4), and a supplying step (S6). In the conveying step, absorbent articles aligned in multiple rows along a first direction are conveyed on a first conveying path in a second direction orthogonal to the first direction. In the moving step, rows of absorbent articles that are either even-numbered or odd-numbered when counted along the first direction from the row of absorbent articles farthest upstream in the first direction are moved to a second conveying path different from the first conveying path. In the supplying step, after rows of absorbent articles of divided groups have been moved to the second conveying path, the rows of absorbent articles are conveyed in the first conveying path and the second conveying path in a direction orthogonal to a longitudinal direction of the absorbent articles, and are supplied into respective folding devices corresponding to each row of absorbent articles among a plurality of devices for folding the absorbent articles.

Abstract: The present invention aims to achieve both a function of diffusing excretions or the like in a longitudinal direction of an absorber and maintenance of adhesion to a wearer in a direction orthogonal to the longitudinal direction. The absorber includes a top sheet (21), a back sheet (22) opposed to the top sheet (21), and an absorbent core (23) extending in a predetermined longitudinal direction between the top sheet (21), and the back sheet (22) and configured to absorb excretions or the like of the wearer. The absorbent core (23) has a plurality of opening portions (23a) each having a shape that opens toward the top sheet (21) and extends in the longitudinal direction and each arranged in the longitudinal direction. An interval (G1) in the longitudinal direction between two opening portions (23a) adjacent to each other among the plurality of opening portions (23a) is set to a dimension equal to or larger than a dimension (D1) in the longitudinal direction of each of the two adjacent opening portions (23a).

Abstract: The front part and the rear part of a diaper main body are each attracted by a first belt and a second belt arranged so as to separate from each other as the first belt and the second belt move to the downstream side of the conveying path. The diaper main body is attracted by the first belt only in a range other than a non-attracting range thereof covering from a crease to a prescribed position in a longitudinal direction. When the respective belts are moved, the front part and the rear part of the diaper main body are separated from each other in a state in which the diaper main body separates from the first belt in the non-attracting range. Then, respective side panels are folded inward between the front part and the rear part of the diaper main body that separate from each other.

Abstract: An absorbent body production device and an absorbent body production method can suppress scattering of an absorbing substance during spraying of the absorbing substance to a substrate. A substrate is conveyed along a rotating outer circumferential surface of a conveyance drum. A granular absorbing substance is discharged from a spray port of a spray apparatus facing the outer circumferential surface of the conveyance drum, and the absorbing substance is sprayed to the substrate which is conveyed along the outer circumferential surface of the conveyance drum. The spray position at which the absorbing substance is sprayed to the substrate is controlled. For example, the position of the spray port of the spray apparatus, or the angle at which the absorbing substance is discharged from the spray port of the spray apparatus is controlled.
