Patent ID: 11166859

Abstract:
Disclosed is a method of manufacturing a wearable article assembled by a front belt, a back belt, and a central chassis, the central chassis having a front waist region and a back waist region separated from each other by a crotch region, wherein at least one of the front belt and the back belt is formed by an elastic belt, the method may comprise making the elastic belt and joining to the central chassis by the steps of: 1) advancing a first layer of continuous sheet having a first surface and an opposing second surface in a machine direction and defining a width in a cross machine direction; 2) advancing a second layer of continuous sheet having a first surface and an opposing second surface in the machine direction and having a smaller width than the first layer of continuous sheet; 3) advancing a first group of elastic bodies in the machine direction in a stretched state; 4) joining the first group of elastic bodies between the first surface of the first layer and the first surface of the second layer of continuous sheets to form a primary elastic belt precursor; 5) advancing a second group of elastic bodies in the machine direction in a stretched state; 6) joining the second group of elastic bodies to the first surface of the first layer of continuous sheet of the primary elastic belt precursor; 7) joining the central chassis to the second surface of the second layer of continuous sheet; and 8) folding the first layer of continuous sheet to form a first layer fold over of continuous sheet, such that at least one of the second group of elastic bodies is directly joined between the first surface of the first layer of continuous sheet and the first surface of the first layer fold over of continuous sheet.
