A method of continuously making a disposable pants-type diaper includes feeding first and second webs in a machine direction and bonding the first and second webs together to obtain first composite web. From the first composite web, a substantially circular section defined between each pair of the adjacent chassis in the middle region as viewed in the cross direction is clipped out to obtain a second composite web. The second composite web is folded in two and halves of the second web facing each other are locally bonded together by bonding agent to obtain a third composite web. The third composite web is provided on both sides of a cutting line extending in the cross direction with seal regions to obtain a fourth composite web and finally the fourth composite web is cut along the cutting line to obtain the individual pants-type diapers.
