Problems solved by technology

[0010] In addition, in the above case, when the fabrics are joined to each other, there may be a possibility of poor sealing due to the biting of the granules into the sealing device.

Embodiment 1

[0044] Hereinafter, Embodiment 1 of the present invention will be described with reference to the drawings.

[0045] Figure 1 to Figure 7 Example 1 is shown.

[0046] Wearing item 1:

[0047] Such as figure 1 As shown, the wearing article 100 of this embodiment includes an absorbent body (diaper body) 200 , a front waist portion 301 , and a rear waist portion 302 . The absorbent main body 200 has a front part 201 covering the wearer's front waist, a back part 202 covering the wearer's back waist, and a crotch part 203 covering the crotch between the front part 201 and the back part 202 .

[0048] The crotch portion 203 is connected with the front portion 201 and the rear portion 202 and extends along the longitudinal direction Y perpendicular to the waistline direction X. The front waist portion 301 and the rear waist portion 302 may be joined together at the time of wearing, or may be joined in advance before wearing.

[0049] Three-dimensional gathers (not shown) may b...

Embodiment 2

[0102] Figure 8 ~ Figure 10 Example 2 is shown.

[0103] As shown in the above-mentioned figures, in the present embodiment, no ejection holes are provided in the non-suction region 4A. In the case of this example, also with the Figure 5 ~ Figure 7 Examples of similarly, such as Figure 8 ~ Figure 10 As shown, as the carrier fabric 1 proceeds to the downstream of the conveying route, the granular objects 3 in the non-suction region 1A of the carrier fabric 1 tend to gather in the suction region 1B.

[0104] In the second embodiment, the method of arranging the granular bodies 3 on the suction region 1B of the carrier fabric 1 is the same as that in the first embodiment, and thus its description is omitted. The situation of this embodiment 2 and Figure 5 Unlike Example 1, the effect of blowing off the granular bodies 3 by the blowing of the second air α2 from the spray hole 42 cannot be obtained. Therefore, the reliability of removing the granular bodies 3 on the non-at...

Abstract

A method includes steps of: carrying an air-permeable web while holding the first surface of the web on a carrying surface; dispensing powder particles onto the second surface of the web; drawing the first air from a plurality of suction holes in the carrying surface through the web, thereby holding the powder particles in a predetermined pattern on the second surface of the web; and giving at least a part of the first air flow components flowing in directions along the second surface of the web by means of an airflow deflector opposing the second surface of the web, thereby moving powder particles on non-suction areas between the suction holes on the web, thus arranging the powder particles in a predetermined pattern on the web.

Description

technical field [0001] The present invention relates to a technique for arranging aggregates of granular objects in a predetermined pattern on an air-permeable carrier fabric. Background technique [0002] Disposable wearing articles such as disposable diapers, panties, and feminine hygiene products include an absorbent main body that absorbs bodily fluids. The absorbent main body is a sandwich structure in which an absorbent core is sandwiched between two fabrics. [0003] As an absorbent core part, it has recently been proposed to use only a powdery absorbent polymer without using fluff pulp (Patent Document 1). In this case, a plurality of aggregates of granular bodies are arranged separately from each other in the vertical and horizontal directions, and two fabrics are sealed (bonded) between the aggregates to maintain the arrangement pattern of the aggregates. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: WO2006 / 015138 (Front Pa...
