In addition, as shown in Figure 4 B, fixed part 41 and face connecting part 44 can be mutually temporary fixed by temporary fixed dose of H1.

In addition, can use hot-melt resin or bonding agent as described temporary fixed dose of H1, H2.In addition, temporary fixed dose of H1, H2 are preferably located at a plurality of positions in fabric bight, but for convenience, chart a position is only shown in each figure.

Next, according to Fig. 7 and Fig. 8, one example of the manufacture method of described diaper is described.

First, the manufacture method of described the first joint elements 4 example is explained.

In Fig. 7, Yi Bian X1 transports a pair of serialgram S1 as described base material 43 along its length, Yi Bian melting attaches the continuous fastener material F as described male face fastener 40 on this each serialgram S1.Thus, generate the continuum S2 as described joint elements 4.

Next, at the position that is not pasted with described continuous fastener material F, imaginary the 4th line (broken line) L4 extending along the length direction X1 of this continuum S2 is converted into two-layer by described each continuum S2.Thus, as shown in Figure 2 A and 2 B, make described face connecting part 44 overlapping with respect to described fixed part 41 so that in the on-fixed face 412 of stationary plane 411 opposition sides described in the described fixed part 41 of the first joint elements 4 and described face connecting part 44 disengaged 442 of male face fastener 40 opposition sides mutually face.

The described folded continuum S2 that cuts off Fig. 7 along imaginary the 5th line L5 that is orthogonal to described length direction X1, thus, cuts out each the first joint elements 4 from described continuum S2.Thus, generate a pair of the first joint elements 4.In addition, make described a pair of the first joint elements 4,4 along moving with the direction of length direction X1 quadrature, so that the broken line at the 4th line L4 place is close to each other and the first joint elements 4,4 are not overlapped each other.

After described a pair of the first joint elements 4,4 difference half-twists, be disposed at respectively and form the rear wing 3B of the first continuous web W1 of described rear waist portion, the non-skin face 3b2 at 3B position of living in is upper, and described fixed part 41 is adhesively fixed on the first continuous web W1.Now, the position between described a pair of the first joint elements 4,4 is configured to become the position of imaginary the 3rd line L3 of rear cut the first continuous web W1.

The configuration of described the first joint elements 4,4 and fixing before, near described the 3rd line L3 of described the first continuous web W1, be coated with and be useful on temporary fixed dose of H1 on the non-skin face 3b2 that disengaged 442 of described the first joint elements 4,4 (Fig. 2 B) is temporarily fixed on to rear wing 3B.Therefore, the configuration of described the first joint elements 4,4 and fixedly time, disengaged 442 (Fig. 2 B) of described the first joint elements 4,4 is temporarily fixed on the non-skin face 3b2 of rear wing 3B.

On one side X1 transports and becomes first and second continuous web of front and back waist portion W1, W2 along its length, on one side that diaper body 2 is set up in to described two fabric W1, W2 is upper and fix.Thus, become the continuous duplexer W3 (with reference to Fig. 2 A, Fig. 2 B) of diaper 1.

The described continuous duplexer W3 of Fig. 8 is converted into two-layer in parallel with waistline direction X imaginary First Line L1Chu Jiang crotch 22, so that the first continuous web W1 and the second continuous web W2 are overlapped, namely make front portion 20 and rear portion 21 overlapped (with reference to Fig. 3 A, Fig. 3 B).

Before folding described crotch 22, or after folding described crotch 22, at described rear wing 3B and/or front wing 3F, apply temporary fixed dose of H2 of temporary fixed use.

As shown in Figure 8, after described diaper body 2 folding process, along imaginary the 3rd line L3, at the position of described continuous web W1, W2, cut off described continuous duplexer W3, from continuous duplexer W3, cut out each diaper 1.

After described cutting out, at the imaginary second line L2 place of extending along described longitudinal Y, fold described front wing 3F, rear wing 3B, so that the described a pair of rear wing 3B of Fig. 3 A and front wing 3F and described anterior 20 overlapping.This second line L2 is located at the position near two edge E1 of described diaper body 2.In addition,, before being about to folding described both wings 3F, 3B, also can make the posture half-twist of diaper 1.Like this, generate the diaper 1 shown in Fig. 4 A and Fig. 4 B.

When wing 3F, the 3B of folding described front and back, folding wing 3F, 3B is temporarily fixed on described anterior 20 by described temporary fixed dose of H2.Like this, as shown in Fig. 4 A, Fig. 4 B and Fig. 5, after diaper 1 is folded into compact condition, by bale packing sale.

In addition, Fig. 2 A～Fig. 5 be take a diaper and the fold sequence for above diaper bale packing is shown as unit.

Next, to dressing the step of folded diaper 1 as shown in Figure 5, describe.

In Fig. 5, user is seized the face connecting part 44 of a pair of the first joint elements 4 with the finger of two handss, to arrow X2, X2 direction, draw, the face connecting part 44 that is temporarily fixed on rear wing 3B peels off from rear wing 3B, and the rear wing 3B (3F) that is temporarily fixed on diaper body 2 peels off from diaper body 2.

Like this, as shown in Figure 6, present half-open for the diaper 1 of T font.Afterwards, user is further opened diaper 1, allows wearer dress under the such form of Fig. 6 B.

Under the bale packing state of Fig. 5, at outer surface, there is a pair of male face fastener 40., see in the first situation about using of wearer of this form for this reason, easily expect described male face fastener 40 to extract.In addition, Producer is easy to describe the key diagram of using method.Therefore, the using method of diaper is understandable.

Below other examples of the present invention are explained.

In following Fig. 9 A～Figure 14, by filled circles, represent the part of temporary fixed dose.

As shown in Fig. 9 A～Fig. 9 D, described the first joint elements 4 also can be converted into three layers zigzag.In the case, as shown in Fig. 9 A and Fig. 9 B, a pair of the first joint elements 4,4 engage a block part with the first continuous web W1 after, as shown in Fig. 9 C and Fig. 9 D, while cutting off the first continuous web W1, the first joint elements 4 are cut off together with described the first continuous web W1, can generate two the first joint elements 4,4.

In addition, described the first joint elements 4 may not be leaveed no choice but fold.As shown in Figure 10 A～Figure 10 D, also bonding (fusion) three blocks of base materials 43 form described the first joint elements 4 mutually.

Under bale packing state, described the first joint elements 4 may not non-ly need to be two-layer.As shown in Figure 11 A～Figure 11 D, for example, it is upper and have male face fastener 40 at the second end 43b that the first joint elements 4,4 also can be fixed on the first end 43a of not folded base material 43 rear wing 3B, 3B.

In the case, upper for described the first joint elements 4 being fixed on to rear wing 3B, first, the joint fastener 4A of Figure 11 is disposed to the upper so that joint fastener 4A of the 3rd line L3 on the diaper adjoining each other.Now, near fixed part 41 places of joint fastener 4A both sides the 3rd line L3 of Figure 11 B are fixed on the first fabric W1.

After described fixing, at described the 3rd line L3 place, described joint fastener 4A is cut off and is separated into two together with described the first fabric W1.Thus, on each rear wing 3B, form the first joint elements 4.

The in the situation that of this structure, there is base material 43 without folding.But will be by male face fastener 40 to the inflection of arrow R direction while using, thereby the flaky masterpiece of fixed part 41 of the first joint elements 4 be for described fixed part 41.

In the example shown in Figure 12, the waist portion parts that form rear wing 3B and front wing 3F are attached at the skin face side of diaper body 2.

In the example shown in Figure 13, each wing 3B, 3F are fixed on the end of the waistline direction X of diaper body 2.In the case, example that also can be is as shown in figure 14 such, and longitudinally Y is continuous to form the duplexer W4 of diaper body 2.

As with reference to accompanying drawing, preferred embodiment being described above, but if seeing this description, those skilled in the art easily expect various changes and correction at apparent range content.

For example, diaper body and the front and back wing also can be with formation of fabrics being connected.In the case, on fabric, form lower limb hole.

In addition, also can be after diaper body 2 be set up between first and second fabric or continuous duplexer W3 is converted into after two-layer the first joint elements are fixed on to the part of rear wing 3B.

Therefore, this change and correction should be interpreted as in the scope of the present invention in being defined by the claims.
