Detailed description of the invention
The deployed condition of the disposable diaper obtained by described manufacture method is H type.The disposable diaper of this H type is configured to, and crotch is folded in half and makes each end of veutro body part and each end face pair of dorsal part body part, as required by faced by this end fix each other, packed by packaging process afterwards.Now, the end of described body part can be fixed to and cannot be separated by bonding etc. each other, or the fixed mechanisms such as face fastener also can be used to be fixed as and can to load and unload.
Described disposable diaper is configured to, described veutro body part, dorsal part body part and crotch have the length be equal to each other, when obtaining above-mentioned veutro body part, dorsal part body part and crotch, substrate sheets entirety can not produced and effectively utilizing lavishly, so preferably.
Described each cut-off rule is not defined as given shape, such as, also can be formed as the linearity along described length direction respectively, in this case, the structure of segmenting device can be made to become simple and easy, and easily split.But in the present invention, described cut-off rule can be set as along the described curve-like by central elastic component, also can be comparatively large in the described lateral margin of a side of central part office and substrate sheets or the opposing party distance apart of leaning on, described less by distance described in side edge portions place.
When splitting load part outside described two body part sheet parts and crotch by two curvilinear cut-off rules, without the need to from the two body part sheet parts obtained, the outer load Partial Resection unnecessary part of crotch, the body part of pars intermedia wider width and the narrower crotch exterior body of pars intermedia width just can be formed.In addition, described cut-off rule is along the curve-like by central elastic component, and each elastic component of the two body part sheet parts be partitioned in described segmentation process and the outer load part of crotch is along this curvilinear lateral margin.Thereby, it is possible to obtain the outstanding disposable diaper of stickiness, the waste of material is less and can carry out high efficiency production.
As long as the elastic component that the elastic component being configured at described continuous sheet stretches along prescribed direction, also can be filament and/or shoestring.
Described in these elastic components can configure one or more of in the half of the lateral margin side of the half of the lateral margin side of a side of the width of described continuous sheet and the opposing party by central elastic component respectively.
What configure many respectively describedly also can be configured to described curve-like in the half of the lateral margin side of the half of the lateral margin side of a side of described continuous sheet and the opposing party respectively side by side by central elastic component.Two described cut-off rules can be set as the elastic component curve-like to each other through configuration side by side respectively.In this case, the described central elastic component that leans on becomes body part elastic component respectively in the veutro body part sheet part be partitioned into and dorsal part body part sheet part, near the both side edges of the outer load part of crotch, become leg elastic component respectively.Therefore, the elastic component of body part and leg is configured at continuous sheet in single operation, can simplify operation further.
Described linearity or curvilinear cut-off rule also can be set as leaning on middle body part near the lateral margin side of substrate sheets by central elastic component through than described relative to described, and pass than described by the part of side edge portions near the width center side of substrate sheets.Now, the described central elastic component that leans on leans on middle body described and lean between side edge portions cut-off along cut-off rule.Therefore, for this by central elastic component, become body part elastic component by side edge portions in veutro body part sheet part and dorsal part body part sheet part, near the both side edges of the outer load part of crotch, become leg elastic component by middle body.
In common disposable diaper, at the partial configuration absorber installed overlapping with the crotch in body part.Therefore, preferably the contractility of body part elastic component does not play a role, and sometimes takes to eliminate handling of contractility to the body part elastic component of this part.But, cut off if as described above cut-off rule is set as by central elastic component, then not residual by central elastic component by the part of the installation crotch exterior body in sheet part in two body part, therefore, do not need to eliminate the contractility that this leans on central elastic component, can not produce the contractility utilized lavishly by central elastic component completely.
The outer load part of described crotch also can be cut off at an arbitrary position in crotch monomer segmentation process.But, under described cut-off rule is curvilinear situation, the outer load part of crotch after segmentation forms the shape of repeated arrangement wide cut part and narrow part, when being cut off in described wide cut part, is divided into the pars intermedia of the crotch of monomer to become width narrower.Namely, for the described veutro body part of disposable diaper obtained and at least one party of dorsal part body part, the width being up and down provided with the central part of described crotch is larger than the width up and down at both ends, and the exterior body of described crotch is along with the central part from length direction, and towards two ends, width increases.Consequently, disposable diaper forms the shape along wearer's lower limb week.
Under described cut-off rule is curvilinear situation, in described crotch monomer segmentation process, if outer for described crotch load part cut off in the middle position of described wide cut part and be divided into monomer, then veutro and the dorsal part of the crotch exterior body obtained are formed as same shape.On the other hand, if outer for described crotch load part is divided into monomer cutting off with the position that the middle position of described wide cut part is separated along its length, then the veutro of crotch exterior body and the area of dorsal part different from each other, the absorptive capacity of the such as absorber of a side increases, or can expand dorsal part and wrap into the buttocks of wearer well.
Preferably, described two cut-off rules can make crotch exterior body be formed as symmetrical.
In addition, described veutro body part sheet part and dorsal part body part sheet part also all can be formed as wide cut part and narrow part with the shape of prescribed distance repeated arrangement.In described crotch installation procedure, when make the wide cut part of two body part sheet parts each other opposed, in above-mentioned wide cut part, each end of described crotch exterior body is installed, the central part of the body part of the disposable diaper obtained is formed as wider width, can wrap into the buttocks of wearer well.
In the present invention, in described crotch installation procedure, also can by half pitch phase place that the waist sheet part of a side is staggered in the longitudinal direction, thus make faced by the narrow width part of the wide cut part of veutro body part sheet part and dorsal part body part sheet part divides mutually, each end of described crotch exterior body is installed respectively in the narrow part of the wide cut part of the body part sheet part of a side and the body part sheet part of the opposing party.
Described substrate sheets is not limited to specific material, structure, one or more of non-woven fabrics, synthetic resin etc. can be used alone or in combination.
Such as, described substrate sheets (10) also can be configured to, outside continuous sheet (W1) is mutually stacked with inner side continuous sheet (W2) narrower than its width, the described multiple elastic component (14) of laminated portions configuration of these continuous sheets (W1, W2), and make the both side edges in outside continuous sheet (W1) expose to the lateral margin part in the outer part than inner side continuous sheet (W2) as extension configuration section (W3) in advance
After described crotch installation procedure (S5), also the lateral margin of described outside continuous sheet (W1) along inner side continuous sheet (W2) can be bent, described extension configuration section (W3) is laminated in described inner side continuous sheet (W2).
In this case, the extension configuration section upward of outside sheet material is turned back in the upper edge of each body part and is laminated in the upper portion of inner side sheet material.Consequently, the upper edge that this disposable diaper is formed as veutro body part and dorsal part body part, by the coated state of outside continuous sheet, is peeling in this upper edge without the need to worrying, better appearance.
In addition, in this case, between the extension configuration section that each end of the length direction of described crotch is configured in outside sheet material and inner side sheet material, the seepages such as urine can be prevented well further thus.
In addition, as described inner side continuous sheet, also can be used in two inner side continuous sheets of the lateral margin side of a side of substrate sheets and the lateral margin side difference configured separate of the opposing party, and each inner side continuous sheet has lamellar rib collar respectively at the side end of the central part side of substrate sheets.
In this case, the part forming the inner side continuous sheet of substrate sheets doubles as lamellar rib collar, can to produce the disposable diaper in the both sides of crotch with lamellar rib collar at a low price.
It should be noted that, described absorber installation procedure also can perform being divided into any time before the disposable diaper of monomer.Such as, also after described crotch installation procedure, respectively absorber can be installed at each crotch exterior body being fixed on body part sheet part.Also before described base material segmentation process, at predetermined intervals absorber can be installed at the width middle body of described substrate sheets, or after described base material segmentation process, at described crotch outer load spaced-apart predetermined distance, absorber be installed.In these cases, the top layer sheet that is made up of liquid-permeable sheet can be supplied continuously and be installed as the state covering absorber, or the bottom chip be made up of opaque liquid sheet supplied continuously and is installed between absorber and substrate sheets etc.
