A method for manufacturing a disposable underpants type diaper provided with a separator for preventing stool from touching the skin. A bending body of a sheet piece (20) for forming a separator (20a) is fixed to the inner surface of the front portion or the rear portion in the inseam region (6) of a diaper basic body having the inseam region (6), the front waist region (7) and the rear waist region (8). The bending body is obtained by bending the sheet piece (20) along the center line in the first width direction thereby superimposing a first half body and a second half body forming the sheet piece (20) and then bonding the end edges (21, 22) in both half bodies at the central portion in the width direction (X). In a state where the first width direction center line is brought close to the second width direction center line dividing the diaper basic body (10a) into two in the front and back direction, inner surfaces at the front portion or rear portion of the inseam region (6) are superimposed, the outer surface at the opposite side edges of the first half body and the inner surface of the inseam region (6) are joined and the portion between the opposite side edges is separated from the inner surface. Subsequently, the diaper basic body (10a) is bent along the second width direction center line, the inner surface of the diaper basic body (10a) and the outer surface at the opposite side edges of the second half body are bonded and the portion between the opposite side edges is separated from the inner surface. Inner surfaces at the side edges (7a, 8a) of the front and rear waist regions (7, 8) of the diaper basic body (10a) thus bent are bonded to form the shape of underpants type. |
