Embodiment Construction

[0026] Hereinafter, the present invention will be described based on preferred embodiments thereof with reference to the drawings.

[0027] Here, the sheet-welded body manufactured by the manufacturing apparatus of this embodiment and the manufacturing method of this embodiment, that is, a sheet-welded body having a sealed edge portion in which a plurality of sheets are welded in a state where their edges are overlapped, is, for example, figure 1 and figure 2 Shown is a pants-type disposable diaper 1 including an exterior body 3 having a pair of side seal portions 4 , 4 . First, based on Figure 1 ~ Figure 3 The underpants type disposable diaper 1 will be described.

[0028] Such as figure 1 and figure 2 As shown, the diaper 1 is a pants-type disposable diaper, which has: an absorbent main body 2; The side edges of the exterior body 3 in the side portion 1A are joined to the side edges of the exterior body in the back side portion 1B to form a pair of side seals 4, 4, a...

Abstract

A device (20) for producing a fused sheet body is provided with: an irradiation head (35) having a lens (351); a support member (21) for transporting a belt-like sheet laminate (10); and a pressing member (24) for applying pressure to the sheet laminate (10). The support member (21) has slit-like opening parts (27) through which laser light (30) can pass. In cross-sectional view, both end parts (21e) of the support member (21) forming the opening parts (27) have tapered parts (211), the space therebetween being wider towards the irradiation head (35) than towards the pressing member (24). The production device (20) cuts the sheet laminate (10), to which pressure is applied, by irradiating same with laser light (30) along the opening parts (27), and fuses the cut edges while the edges overlap, thereby continuously producing a fused sheet body (3) having sealed edges (4).

Description

technical field [0001] The present invention relates to a method for manufacturing a sheet-welded body having a sealed edge portion in which a plurality of sheets are welded in a state where the edges are overlapped, and a method for manufacturing the same. Background technique [0002] At present, in the manufacturing process of absorbent articles such as disposable diapers and sanitary napkins, a heat roller device is widely used for joining overlapping sheets. In addition, as another bonding method, a method of welding using a laser beam is also known (for example, refer to Patent Documents 1 and 2). [0003] Patent Document 1 discloses a laser irradiation device for cutting a metal mesh cloth, which includes a mirror for reflecting laser light, a condenser lens for condensing the reflected laser light, and a processing nozzle for irradiating the condensed laser light. In addition, Patent Document 2 discloses a laser irradiation device that irradiates laser light through...
