Embodiment 1

[0044] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0045] Figure 1A ~ Figure 2B Example 1 is shown.

[0046] Diaper 1:

[0047] Figure 1A The illustrated diaper (an example of a wearing article) 1 is, for example, a pant-type diaper, and is provided with a crotch portion 10 covering the crotch of the wearer, a front waist portion 11 covering the abdomen side of the wearer, and a front waist portion covering the wearer's back side. Covered rear waist portion 12 .

[0048] The diaper 1 includes an absorbent main body 2 and an exterior sheet 3 . The said absorptive main body 2 has the front part 2f, the crotch part 2c, and the back part 2b which respectively cover the front surface of a wearer's waist, a crotch, and a back surface.

[0049] The outer packaging sheet 3 is formed of an air-permeable material (such as non-woven fabric). The exterior sheet 3 is formed of an anisotropic nonwoven fabric that is stretchable ...

Embodiment 2

[0085] Figure 3A ~ Figure 4 Example 2 is shown.

[0086] In this embodiment 2, Figure 3A The absorbent main body 2 is arranged from the front end to the rear end of the outer packaging sheet 3 in the longitudinal direction X. In the present embodiment 2, the elastic band 4 is not provided.

[0087] In this case, as Figure 4 As shown, after the continuous laminate W2 is laminated on the continuous sheet W1, the continuous sheet W1 and the continuous laminate W2 are sequentially cut at the cutting line CL.

Embodiment 3

[0089] Figure 5A ~ Figure 6B Example 3 is shown. In Example 3 described below, the differences from the aforementioned Example 1 will be mainly described.

[0090] Diaper 1:

[0091] Such as Figure 5A As shown, in the diaper 1 of the third embodiment, the front and rear exterior sheets 3f and 3b are separated from each other at the crotch portion 10 between the front waist portion 11 and the rear waist portion 12 . The front and rear wrapping sheets 3f, 3b are separated from each other along the longitudinal direction X. The absorbent main body 2 is bonded and bonded to the separated pair of front waist portion 11 and rear waist portion 12 with, for example, an adhesive, so as to be bridged between the front waist portion 11 and the rear waist portion 12 . Therefore, the absorbent main body 2 covers the crotch portion 10 .

[0092] The front waist part 13 and the back waist part 14 in which the absorptive main body 2 is not arrange|positioned are formed in the front wai...

Abstract

Provided is a production method for a disposable item of clothing that comprises an absorbent body (2) and an outer sheet (3), comprising: a step wherein a continuous sheet with the outer sheet (3), which is expandable / retractable in a waistline direction (Y), is essentially difficult to expand / retract in a conveyance direction (X) perpendicular to the waistline direction (Y), and extends in the conveyance direction, is conveyed in the conveyance direction (X); a step wherein the absorbent body (2) is arranged on top of the continuous sheet with a front section (2f), a crotch section (2c) and a rear section (2b) lined up in the conveyance direction (X); and a step wherein the continuous sheet is cut along an imaginary cutting line that extends in the waistline direction (Y), to provide individual disposable items of clothing with the absorbent body (2) arranged on top of the outer sheet (3).

Description

technical field [0001] The present invention relates to a method of manufacturing disposable wearable articles. Background technique [0002] Conventionally, there has been proposed a method of manufacturing a disposable wearing article while conveying a sheet and a core along a longitudinal direction perpendicular to the girth direction (see Patent Document 1). In the manufacturing method disclosed in Patent Document 1 below, a laminate is formed by disposing a liquid-absorbent core intermittently between continuous top sheet and back sheet, and then cutting the laminate into individual disposable wearing articles. [0003] In addition, the following Patent Document 2 discloses an exterior sheet in which an elastic fabric stretchable in the waist direction and a non-stretch fabric are laminated. However, there is no disclosure regarding the stretchability in the longitudinal direction. Furthermore, nothing is disclosed about the manufacturing method. [0004] prior art l...
