Method for producing disposable worn article

A method for producing a disposable worn article including a core portion that covers a crotch of a wearer and a torso portion that fits to a torso of the wearer, with the torso portion including a back portion and a front portion whose length in an around-the-torso direction is smaller than that of the back portion, and with the core portion being placed so as to bridge between the back portion and the front portion, the method comprising:

• a step of carrying a first web having a first outer side edge portion, which is extending in a longitudinal direction of a continuous web, to be an upper side of a waist portion of a first back portion and a second web having a second outer side edge portion, which is extending in the longitudinal direction of the continuous web, to be an upper side of a waist portion of a second back portion in a longitudinal direction of the webs while being parallel to each other and spaced apart from each other;
• a step of forming a combined member by placing a plurality of core portions so as to bridge between the first web and the second web while being spaced apart from each other in the longitudinal direction and attaching the core portions to the first web and the second web;
• and
• a step of cutting the combined member, along a line extending in the longitudinal direction, into a first group and a second group so as to divide the combined member in a web width direction into the first group including a portion of the first web to be the first back portion and a portion of the second web to be a first front portion and the second group including a portion of the second web to be the second back portion and a portion of the first web to be a second front portion and so that the first and second groups each include the core portions and so that the first outer side edge portion of the first web is in the first group while outside the second group and the second outer side edge portion of the second web is in the second group while outside the first group.
