The present invention provides a method of continuously making a disposable pants-type diaper having a body waste receiving pocket adapted to be easily aligned with the wearers external genitals and anus. A first web comprising chassis continuously arranged in a transverse direction thereof is continuously fed in a machine direction MD wherein each of the chassis comprises a crotch region, a front waist region and a rear waist region. A second web comprising sheet members continuously arranged in the transverse direction thereof is continuously fed onto the first web wherein each of the sheet members is destined to be attached to the inner surface of the associated chassis in the crotch region thereof and thereby to form a body waste receiving pocket. The second web is folded back onto itself in a cross direction CD and locally bonded to each other along opposite edges thereof at regular pitches each corresponding to a width of the individual chassis to obtain a third web having seal regions. The third web is superposed on the first web so that the seal region is located in the transverse middle of the chassis and then the first web and the third web are bonded to each other along regions corresponding to opposite side edges the crotch region in the chassis to obtain a first composite web. The first web in the first composite web is folded in the cross direction CD and superposed on the third web so that the first web and the third web overlap each other are bonded together along the regions destined to define the opposite side edges of the crotch region in the chassis to obtain a second composite web. From between the adjacent chassis in the second composite web, substantially semicircular web pieces are clipped out to obtain third composite web. The third composite web is provided on both sides of a cutting line extending in the cross direction CD with seal regions extending along the cutting line to obtain a fourth composite web and finally the fourth composite w
