1. A method for manufacturing an around-torso portion of a worn article, wherein:
the around-torso portion includes:
first sheets, each having a female touch fastener at a front end and a rear end thereof in a conveyance direction, the female touch fastener at the front end and the female touch fastener at the rear end being spaced apart from each other in the conveyance direction in each of the first sheets, and
second sheets, each having a male touch fastener at a rear end and a front end thereof in the conveyance direction, the male touch fastener at the rear end and the male touch fastener at the front end being spaced from each other in the conveyance direction in each of the second sheets,

wherein the first sheets and the second sheets are arranged alternating and continuous with each other in the conveyance direction,
the manufacturing method comprising the steps of:
intermittently conveying the first sheets by a first drum;
conveying a preceding second sheet, of the second sheets, toward a junction with the first drum by a first pad of a second drum, and conveying the preceding second sheet so that the male touch fastener at the rear end of the preceding second sheet, which is spaced apart from the male touch fastener at the front end of the preceding second sheet, overlaps with the female touch fastener at the front end of one first sheet of the first sheets, which is spaced apart from the female touch fastener at the rear end of the one first sheet;
conveying a subsequent second sheet, of the second sheets, toward the junction with the first drum by a second pad of the second drum, and conveying the subsequent second sheet so that the male touch fastener at the front end of the subsequent second sheet, which is spaced apart from the male touch fastener at the rear end of the subsequent second sheet, overlaps with the female touch fastener at the rear end of the one first sheet, which is spaced apart from the female touch fastener at the front end of the one first sheet; and
tentatively fastening one of the first sheets and one of the second sheets to each other by partially attaching the one of the first sheets and the one of the second sheets to each other in a tentative attachment area,
the tentative fastening step performed in an overlapping portion between the one of the first sheets and the one of the second sheets, wherein the tentative attachment area excludes the female touch fastener at the front and rear ends and the male touch fastener at the rear and front ends,
conveying the preceding second sheet and the subsequent second sheet by the second drum with the preceding second sheet being held on the first pad and with the subsequent second sheet being held on the second pad, and
conveying the one first sheet, providing to bridge between the first pad and the second pad, by the second drum along a circumference of the second drum after exiting the junction.
