no. 1 approach

[0038] A first embodiment of the present invention will be described below with reference to the drawings.

[0039] FIG. 1 is a bottom view of a part of the manufacturing apparatus of the first embodiment, FIG. 2 is a front view of the same apparatus, and FIG. 3 is a schematic view showing the outline of the same apparatus.

[0040] This manufacturing device is a device for installing two groups of elastic materials X (Fig. 5) on the first fabric W1 conveyed longitudinally with a determined line (track). As shown in Fig. 3, the device is configured with the first fabric W1 and The pair of pinch rolls 1 clamped together by the superimposed second fabric W2 of the first fabric W1 has first and second levers (first and second moving parts) 5 and 6 arranged near 1 . As shown in Figure 2, this device consists of a guide shaft 2, a first slider 3 and a second slider 4 provided on this guide shaft 2, a first lever 5 provided on this first slider 3, and the above-mentioned Main compo...

no. 2 approach

[0076] 7 and 8 show a second embodiment.

[0077] As shown in FIG. 7, this manufacturing apparatus has a 1st mounting mechanism A and a 2nd mounting mechanism B. As shown in FIG.

[0078] The first mounting mechanism A has a first displacement device 13 , at least one first lever 5 guided close to the pinch rollers 1 , 1 of the elastic material X. The second mounting mechanism B has a second displacement device 14 , at least one second lever 6 guided close to the pinch rollers 1 , 1 of the elastic material X. The first moving device 13 makes the first lever 5 reciprocate in the transverse direction of the first fabric W1. On the other hand, the second moving means 14 reciprocates the second lever 6 in the transverse direction of the second fabric W2.

[0079] As shown in FIG. 8(a), the moving devices 13, 14 are respectively equipped with a pair of transmission wheels 15a, 16a, and belts 15 and 16 are installed between the transmission wheels 15a, 16a. One of the above-menti...

Abstract

The present invention provides a device for manufacturing a disposable wearing article with which an elastic member is attached on a web along a prescribed locus. The present invention concerning the disposable wearing article is provided with a pair of nip rolls 1, 1 for holding the webs W1 and holding the elastic member X in the webs, a first mobile member 5 to be moved in parallel with an axial line H to be the rotary center of the nip rolls 1, a first deriving part 5a which is formed in a first mobile member 5 so as to derive at least one elastic member in the webs W1 on an upstream where the webs is held. The radius of at least one of the nip rolls 1, 1 is set to about 15 mm-35 mm and a distance D between a plane including the axial lines of the pair of nip rolls 1, 1 and a point where the first deriving part 5a releases the elastic member X is set to be about <=30 mm.

Description

technical field [0001] The present invention relates to an apparatus and method for manufacturing disposable wearing articles such as paper diapers and disposable underpants. Background technique [0002] In Japanese Unexamined Patent Publication No. 3-33201, a device is disclosed in which rubber bands are crossed around the leg openings of disposable shorts. [0003] However, JP-A-3-33201 does not disclose the relationship between the insertion distance of the rubber band and the rubber band arranged in the fabric. Contents of the invention [0004] It is therefore an object of the present invention to provide a manufacturing device and method capable of placing elastic material in a fabric along a defined trajectory, such as a disposable wearing article. [0005] The device of the present invention comprises a pair of pinch rollers that clamp the first fabric and the first elastic material together; a first moving part that enables the above-mentioned first fabric to mo...
