A method of manufacturing a wearable article assembled by a front elastic belt, a back elastic belt, and a center chassis, the center chassis having a front waist region and a back waist region separated from each other by a crotch region, and having a longitudinal axis and a lateral axis; a proximal direction closer to the longitudinal center of the article and a distal direction farther from the longitudinal center of the article; the method comprising steps of: advancing a first layer of continuous sheet having a first surface in a machine direction, and defining a width in a cross direction; advancing a second layer of discrete sheet having a first surface in the machine direction, the second layer of discrete sheet being a repetition of discrete sheets discontinuous in the machine direction having a smaller width than the first layer of continuous sheet; advancing a first group of elastic bodies in the machine direction in a stretched state, wherein all of the first group of elastic bodies are intermittently directly joined to the first surface of the first layer of continuous sheet and the first surface of the second layer of discrete sheet; directly joining the first surface of the first layer of continuous sheet and the first surface of the second layer of discrete sheet; advancing a second group of elastic bodies in the machine direction in a stretched state, wherein the second group of elastic bodies are directly joined to the first surface of the first layer of continuous sheets in regions outward of the second layer of discrete sheet in the width direction, wherein the second group of elastic bodies are intermittently directly joined to the first surface of the first layer of continuous sheet, wherein a portion planned for the center chassis to overlay the second group of elastic bodies are left unjoined; directly joining the center chassis with the first layer of continuous sheet overlapping regions in which the first group of elastic bodies are not directly joined to the first surface of the first layer of continuous sheets; and folding the first layer of continuous sheet to form a first layer fold over of continuous sheet, and directly joining the first layer of continuous sheet and the first layer fold over of continuous sheet, wherein the first layer fold over of continuous sheet overlaps all of the second group of elastic bodies, and at least partially overlaps the center chassis and the second layer of discrete sheet.
