Method for producing disposable worn article

A method for producing a disposable worn article comprising a pair of around-torso members configured to cover a torso of a wearer and extend in a girth direction, and an absorbent body provided so as to bridge between the pair of around-torso members, extending in a longitudinal direction perpendicular to the girth direction, and configured to cover a crotch of the wearer, the method comprising the steps of:

• cutting a continuous non-woven fabric, which has a pair of side edge portions extending in a carrying direction, along a wave-shaped cutting line having a predetermined rectangular shape while the continuous non-woven fabric is carried in the carrying direction so as to divide the continuous non-woven fabric into a first continuous divided non-woven fabric and a second continuous divided non-woven fabric,
• the first continuous divided non-woven fabric having first protruding portions protruding in a width direction perpendicular to the carrying direction from a first continuous portion continuous in the carrying direction, and the first continuous divided non-woven fabric forming one of the pair of around-torso members,
• the second continuous divided non-woven fabric having second protruding portions protruding in the width direction from a second continuous portion continuous in the carrying direction, and the second continuous divided non-woven fabric forming another one of the pair of around-torso members;
• placing at least one elastic member stretchable in the carrying direction at least on the first and second protruding portions of the first and second divided non-woven fabrics, or on base portions of the first continuous portion located at the same positions in the carrying direction as the first protruding portions and on base portions of the second continuous portion located at the same positions in the carrying direction as the second protruding portions;
• folding the first and second divided non-woven fabrics so that the elastic member is sandwiched between the base portions and the first protruding portions, adjacent to the base portions, of the first divided non-woven fabric and between the base portions and the second protruding portions, adjacent to the base portions, of the second divided non-woven fabric, and so that layered portions are formed in the first and second divided non-woven fabrics, the layered portions of the first divided non-woven fabric including the first protruding portions laid on the base portions adjacent to the first protruding portions, and the layered portions of the second divided non-woven fabric including the second protruding portions laid on the base portions adjacent to the second protruding portions;
• changing a positional relationship between the first and second divided non-woven fabrics so that positions of the base portions of the first continuous divided non-woven fabric in the carrying direction are aligned with positions of the base portions of the second continuous divided non-woven fabric in the carrying direction;
• and
• after the changing step, placing the absorbent body so as to bridge between, and to overlap, a non-layered portion of the first continuous divided non-woven fabric and a non-layered portion of the second continuous divided non-woven fabric, the non-layered portion of the first divided non-woven fabric extending between two of the layered portions adjacent to each other in the carrying direction and the non-layered portion of the second divided non-woven fabric extending between two of the layered portions adjacent to each other in the carrying direction, while the first and second continuous divided non-woven fabrics are carried generally in parallel to each other in the carrying direction, thereby producing a continuous laminate.
