Embodiment 1

[0052] Hereinafter, the structure of the wearing article 1 which concerns on one Example of this invention is demonstrated based on drawing.

[0053] Figure 1 to Figure 7 Example 1 is shown.

[0054] like figure 1 as well as Figure 2A As shown, the wearing article 1 of this embodiment includes an absorbent main body 2, a front waist member 3F, and a rear waist member 3B. The absorbent main body 2 has a front portion (front waist portion) 20 covering the front body of the wearer and extending in the waist direction X, and a rear portion (rear waist portion) covering the rear body of the wearer and extending in the waist direction X. ) 21, and the crotch portion 22 covering the crotch between the front portion 20 and the rear portion 21.

[0055] The crotch portion 22 is connected to the front portion 20 and the rear portion 21 and extends along a longitudinal direction Y perpendicular to the waist direction X. The absorbent main body 2 constitutes part or all of the crot...

Embodiment 2

[0099] Figure 9 ~ Figure 13 Example 2 is shown. Hereinafter, the difference between Example 2 and Main Example 1 will be mainly described.

[0100] In the first embodiment, the periphery of the notch 40 is completely surrounded by the outer non-woven fabric 4, but in Figure 9 as well as Figure 10 In this embodiment, the periphery of the notch 40 is not completely surrounded by the exterior nonwoven fabric 4 .

[0101] Such as Figure 10 As shown, the outer nonwoven fabric 4 is formed with a notch 40 that is depressed from the end in the longitudinal direction Y toward the center. End edges of the exterior nonwoven fabric 4 in the longitudinal direction Y are not connected in the waist direction X, but are separated from each other in the waist direction X via the notch 40 .

[0102] That is, both ends of the notch 40 in the waist direction X are defined by the exterior nonwoven fabric 4, and the longitudinal direction Y of the notch 40 is defined by the exterior nonwov...

Abstract

The manufacturing method of the disposable wearing article of the present invention includes the following steps: conveying the continuous nonwoven fabric for exterior that becomes the exterior nonwoven fabric along the longitudinal direction, and forming openings (notches) in the continuous nonwoven fabric for exterior. Process; after the opening process, the skin surface of the continuous non-woven fabric used for external packaging is pasted into a continuous resin sheet that becomes a resin sheet and the first laminating process is used to block the opening with the continuous resin sheet; on the skin surface of the continuous resin sheet The process of arranging the absorbent core to obtain a continuous laminated body as an absorbent main body; in order to obtain the absorbent main body of each wearing article from the continuous laminated body, the continuous laminated body is extended in the width direction perpendicular to the longitudinal direction. The process of cutting along the imaginary cutting line; and the second bonding process of overlapping and bonding at least one laminate of continuous non-woven fabrics to become a waist member on the non-skin surface of the outer non-woven fabric so as to cover the notch.

Description

technical field [0001] The present invention relates to a method of manufacturing disposable wearing articles. Background technique [0002] Conventionally, in the process of manufacturing diapers, the sheet is trimmed with a cutting machine in order to form leg holes through which legs can pass. As such a manufacturing method, there is known an H-type manufacturing method in which leg holes are not formed by trimming to reduce material waste and cost. [0003] In the H-type manufacturing method, an absorbent main body is erected between a pair of waist members (Patent Document 1). [0004] In the H-shape manufacturing method, the trimming of the leg holes is not required by making the diaper an H-shape. However, in the invention of Patent Document 1, the liquid-impermeable back sheet, that is, a resin sheet such as polyethylene, is exposed on the non-skin side of the crotch region, resulting in poor appearance and feel. [0005] Then, the paper diaper which arrange|posit...
