Claim:
A method of manufacturing an absorbent article, comprising the steps of: forming a leg circumferential region on a web which is continuously fed in a conveyance direction on a conveyance belt; and folding the web along a center line, the folding bisecting a dimension of the web in a cross direction perpendicular to the conveyance direction to define first and second half regions respectively on two sides of the center line, so that the second half region comes closer to or overlaps the first half region, wherein said folding includes conveying the first half region on the conveyance belt while guiding the second half region towards the first half region by a guide unit including a plurality of guide rollers so that an inclination angle of the second half region in relation to the first half region becomes gradually smaller from the guide rollers on an upstream side to the guide rollers on a downstream side in the conveyance direction, in the folding, the first half region is conveyed by and sucked on the conveyance belt while the second half region, which is not sucked on the conveyance belt, is guided by said guide rollers towards the first half region so that a side edge of the second half region is flush with a side edge of the first half region in the conveyance direction, and during said folding, the second half region is guided by a pair of the guide rollers that directly sandwich the second half region therebetween.
