Problems solved by technology

[0012] In order to solve the above-mentioned problems, the disposable wearing article according to the present invention is characterized in that the disposable wearing article has one or more elongated elastic bodies located on one side of a single flexible sheet. side or between a pair of sheets with flexibility (in the case of multiple elastic bodies, for example, in a parallel shape), and are respectively pasted and fixed on the front part and the back part of the sheet in a stretched state, Thus, when the elastic body elastically recovers (i.e., shrinks), the sheet forms a waist gather (i.e., folds, folds, or creases formed at the waist portion),

Embodiment Construction

[0077] Hereinafter, embodiments of the present invention will be described with reference to examples shown in the accompanying drawings. Figure 1-Figure 3 An example of the disposable diaper of the present invention is shown. Figure 1-Figure 3 The illustrated disposable diaper 10 (disposable wearing article) is an example of a so-called bodily fluid absorbent article, and is generally also referred to as a "pants-type paper diaper". The absorber 5 located in the substantially center part of the disposable diaper 10 contains superabsorbent polymer particles, is formed in various shapes such as a flat plate, and the periphery thereof is covered with a plurality of sheets. For example, a top sheet 6 that is in direct contact with the skin is provided on the body side of the absorber 5 (ie, the bodily fluid absorption side), and the outer back sheet 1 is provided on the side opposite to the body (ie, the body fluid non-absorbing side). (1st sheet) and the inner back sheet 2 (2...

Abstract

The invention provides a disposable wearing article having a structure capable of reducing the coating amount (amount of use) of an adhesive and suppressing occurrence of defective products. In addition, the invention provides a manufacturing apparatus and a manufacturing method for easily and inexpensively producing such a disposable wearing article. In the case of a waist gather rubber (30), the adhesive is applied to the outer back sheet and the inner back sheet (1, 2) only in tension areas (TA1, TA2), and a free area (FA) in a relaxed state is formed in a non-adhered state with the back sheet (1, 2). When the wearing article is worn, wrinkles are formed substantially only by the contraction of the tension areas (TA1, TA2) of the wrinkles (30). The free area (FA) in the slack state and the non-adhered state is cut in two at the intermediate position. Each of the cut pieces (301, 301) is integrally connected to an adjoining tension area (TA1, TA2) in a tensioned state and in an adhered state.

Description

technical field [0001] The present invention relates to a disposable wearing article, a manufacturing device and a manufacturing method of the disposable wearing article, in which one or more elongated elastic bodies are arranged on a single sheet material having flexibility (sheet) on one side or between a pair of sheets with flexibility. Specifically, for example, in disposable wearing articles such as disposable diapers and sanitary napkins (these are also articles for absorbing bodily fluids), the present invention is most suitable for waist gathers (that is, folds formed on the waist, pleats or creases), and the present invention is applicable to the manufacture of such disposable wearing articles. Background technique [0002] For example, in a disposable diaper (whether it is a pants type or a belt type), a plurality of sheets (each sheet consisting of a single layer or multiple layers) covers an absorbent body containing superabsorbent polymer particles. Usually, a...
