Abstract: To reduce a discrepancy between sealing areas on outward and homeward paths through which superposed parts of a continuous material are joined to each other, a method for manufacturing a wearable article includes: superposing a first and second parts of a continuous material on each other; winding the continuous material around a rotary drum and conveying the continuous material; and moving a movable part of a sealer unit outward and homeward in a cross direction crossing a conveyance direction, while the continuous material is conveyed, to form liner sealing areas and joining the first and second parts through the formed liner sealing areas. The method includes, after the superposing and before the joining, inhibiting a movement of the first and second parts relative to each other by temporary fastening such as heat sealing at a place at which the first and second parts are to be joined together.

Abstract: Fasteners folded in two are arranged on one main surface of a first continuous body so that ends of the fasteners are arranged on the outside of the one main surface. A second continuous body is laid over another main surface of the first continuous body in a state where one end is bent so as to be laid over the other main surface, and the first continuous body and second continuous body are bonded together to form a composite continuous body to which the one end of the fasteners is fixed. The composite continuous body is cut to form a piece on which the pair of fasteners is arranged only in a first region. The piece is folded in two along an imaginary line and overlapped, and then the other end of the fasteners is bent and laid over and fixed to a second region.
