Embodiment

[0039] The present invention can be more clearly understood from the following description of preferred embodiments with reference to the attached documents. However, the examples and drawings are only for illustration and description, and should not be used to limit the scope of the present invention. The scope of the invention is defined by the claims. In the drawings, the same reference numerals in a plurality of drawings indicate the same or corresponding parts.

[0040] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0041] figure 1 The manufacturing apparatus of stretchable laminated body W is shown.

[0042] In the stretchable laminate W of this embodiment, a linear elastic member F (F1, F2) extending in the width direction Y transverse to the conveying direction X of the sheets S1, S2 is interposed between a pair of sheets S1, S2. ),Such as Figure 9C as well as Figure 9D As shown, the stretchable laminate W ...

Abstract

The present invention is a manufacturing method for a stretch laminate (W) which stretches and contracts in a width direction (Y), upon which a plurality of linear elastic members (F) are disposed so as to extend in the width direction (Y) between a first sheet (S1) and a second sheet (S2) across a transport direction (X) of the sheets (S1 and S2), wherein the method is provided with a step in which: on the surface of a folded-back roll (8) which becomes of smaller diameter toward both ends from the center of the width direction (Y), a complex (W1) is transported while coming into tactile contact with the surface on the opposite side of the first sheet (S1) in the second sheet (S2) of the complex (W1), whereupon, by the central portion (Wc) of the complex (W1) shrinking in the width direction (Y) so as to accompany shrinking of the central portion (Fc) of the elastic member (F), the folded-back portions (Sf) of the first sheet (S1) are folded back so as to overlap both side edge portions (Se) of the second sheet (S2).

Description

technical field [0001] The present invention relates to a method and an apparatus for manufacturing a stretch laminated body. Background technique [0002] Disposable diapers and underpants adopt a structure in which a stretchable laminate is disposed on side walls and a main body so that the diaper and the like are fitted to the body. As a method for producing such a stretchable laminate, a method is known in which a helical elastic member is fed between a pair of belts held by nip rollers in a direction intersecting with the conveying direction of the belt using a conveyor belt, This elastic member is sandwiched between the pair of belts and fixed (Patent Document 1). [0003] In addition, after sandwiching the elastic member with two sheets, the elastic member is cut on both sides of the conveying mechanism, and the laminated sheet is removed from the conveying mechanism. However, in order to cover the shrunk end of the cut elastic member, it is necessary One of the two...
