Diaper manufacturing method

Abstract

The method includes: a step of carrying a diaper body 2 in a longitudinal direction X perpendicular to a girth direction Y; a step of forming panel assemblies P, each including a side panel 3 and a tape fastener 4 attached to the side panel 3, in which the panel assemblies P are each folded along a virtual first line L 1 extending in the longitudinal direction X so that the tape fastener 4 faces the side panel 3; a step of attaching the panel assemblies P to the diaper body 2 being carried; a folding step of folding each panel assembly P along a virtual second line L 2 extending in the longitudinal direction X so that the panel assembly P, which has been folded along the first line L 1, lies on the diaper body 2; and a folding-up step of folding up the diaper body 2 along a virtual third line L 3 extending in the longitudinal direction X at a position that does not overlap the panel assemblies P, after the folding step.

1 . A method for manufacturing a diaper comprising: a diaper body including a front portion covering a front side of a wearer, a back portion covering a back side of the wearer, and a crotch portion between the front portion and the back portion; a pair of side panels secured respectively to side edge portions of the back portion opposing each other in a girth direction; and a tape fastener provided at each of end portions of the side panels in the girth direction, wherein each of the side panels is attached to the front portion via the tape fastener to thereby fasten the diaper around a torso of the wearer when the diaper is worn, the method comprising:
 a step of carrying the diaper body in a longitudinal direction perpendicular to the girth direction;   a step of forming panel assemblies, each including each of the side panels and the tape fastener attached to each of the side panels, in which the panel assemblies are each folded along a virtual first line extending in the longitudinal direction so that the tape fastener faces each of the side panels;   a step of attaching the panel assemblies to the diaper body being carried;   a folding step of folding each of the panel assemblies along a virtual second line extending in the longitudinal direction so that each of the panel assemblies, which has been folded along the first line, lies on the diaper body; and   a folding-up step of folding up the diaper body along a virtual third line extending in the longitudinal direction at a position without overlapping the panel assemblies, after the folding step,   wherein the step of forming the panel assemblies, the step of attaching the panel assemblies, the folding step and the folding-up step are performed for each of a left side and a right side in the girth direction for each diaper body.   
     
     
         2 . A method for manufacturing a diaper according to  claim 1 , wherein the panel assemblies are folded along the first line before the step of attaching the panel assemblies. 
     
     
         3 . A method for manufacturing a diaper according to  claim 1 , wherein the panel assemblies are each folded in the step of forming panel assemblies so that a surface of the tape fastener on which a male touch fastener is formed and a skin-contact surface of each of the side panels face each other. 
     
     
         4 . A method for manufacturing a diaper according to  claim 1 , wherein the panel assemblies are each folded in the step of forming panel assemblies so that an opposite surface of the tape fastener opposite to a surface thereof on which a male touch fastener is formed and a non-skin-contact surface of each of the the side panels face each other. 
     
     
         5 . A method for manufacturing a diaper comprising: a diaper body including a front portion covering a front side of a wearer, a back portion covering a back side of the wearer, and a crotch portion between the front portion and the back portion; a pair of side flaps protruding in a girth direction from the back portion of the diaper body; and a tape fastener provided at each of end portions of the side flaps in the girth direction, wherein each of the side flaps is attached to the front portion via the tape fastener to thereby fasten the diaper around a torso of the wearer when the diaper is worn, the method comprising:
 a step of carrying the diaper body in a longitudinal direction perpendicular to the girth direction;   a step of attaching the tape fastener to each of the side flaps;   a first folding step of folding each of the side flaps or the tape fastener along a virtual first line extending in the longitudinal direction so that the tape fastener faces each of the side flaps;   a second folding step of folding each of the side flaps along a virtual second line extending in the longitudinal direction so that the side flaps lie on the diaper body, after the first folding step; and   a folding-up step of folding up the diaper body along a virtual third line extending in the longitudinal direction at a position without overlapping the side flaps,   wherein the step of attaching the tape fastener, the first folding step, the second folding step and the folding-up step are performed for each of a left side and a right side in the girth direction for each diaper body.   
     
     
         6 . A method for manufacturing a diaper according to  claim 5 , wherein each of the side flaps or the tape fastener is folded in the first folding step so that a surface of the tape fastener on which a male touch fastener is formed and a skin-contact surface of each of the side flaps face each other. 
     
     
         7 . A method for manufacturing a diaper according to  claim 5 , wherein each of the side flaps or the tape fastener is folded in the first folding step so that an opposite surface of the tape fastener opposite to a surface thereof on which a male touch fastener is formed and a non-skin-contact surface of each of the side flaps face each other.
