Absorbent article for pet and manufacturing method thereof

A manufacturing method of an absorbent article for pet, said absorbent article having a longitudinal direction and a width direction, the absorbent article comprising:

• a liquid permeable top sheet;
• a liquid impermeable back surface layer;
• an absorbent core disposed between the top sheet and the back surface layer;
• a first end portion and a second end portion opposing to each other in the longitudinal direction of the absorbent article for pet;
• a first side portion and a second side portion opposing to each other in the width direction of the absorbent article for pet;
• a first gather portion including a first side sheet that is disposed on a top sheet side of the first side portion, has an outer edge joined with the back surface layer and has an inner edge at least a part of which is a free end;
• a second gather portion including a second side sheet that is disposed on the top sheet side of the second side portion, has an outer edge joined with the back surface layer and has an inner edge at least a part of which is a free end;
• and
• a pair of releasably-joined portions in which the first side sheet is releasably-joined to itself in a state of being folded outward in the width direction, in the first end portion and the second end portion,
• the manufacturing method comprising:
• a continuous body forming step of forming a continuous body for forming the absorbent article in which a plurality of absorbent cores are arranged at predetermined intervals in the longitudinal direction between a continuous top sheet and a continuous back surface layer, and a continuous first side sheet and a continuous second side sheet are arranged on two sides of the continuous top sheet;
• a first folding step of folding the sides of the continuous body such that the continuous first side sheet and the continuous second side sheet are folded back in the width direction;
• and
• a cutting step of cutting the continuous body after the first folding step at predetermined intervals in the longitudinal direction,
• wherein the pair of releasably-joined portions is formed in the cutting step.
