The present invention is a method for changing the conveyance mode of absorbent article workpieces. The method comprises :(1) performing longitudinal flow conveyance while N (N is an integer of 2 or more) workpiece rows each formed by arranging a plurality of workpieces each having a shape in which a central portion in the longitudinal direction of the workpiece is narrower in the lateral direction of the workpiece than both end portions in the longitudinal direction along the longitudinal direction are arranged in the lateral direction, and performing the longitudinal flow conveyance while both the end portions of the workpieces are adjacent to the central portions of the workpieces adjacent thereto in the lateral direction (2) associating N workpieces included in workpiece rows different from each other from among the N workpiece rows conveyed by the longitudinal flow conveyance in accordance with a predetermined association pattern to form workpiece groups each configured from the N workpieces and (3) with respect to each of the workpiece groups, changing the conveyance of the workpieces of the workpiece group from the longitudinal flow conveyance to lateral flow conveyance. In the formation of the workpiece groups, workpieces adjacent to each other in the lateral direction are associated with each other in accordance with the association pattern.La présente invention est un procédé pour modifier le mode de transport de pièces darticle absorbant. Le procédé comprend : (1) la conduite dun transport de flux longitudinal tandis que des rangées de N (N est un entier de 2 ou plus) pièces chacune formées par agencement dune pluralité de pièces ayant chacune une forme dans laquelle une partie centrale dans la direction longitudinale de la pièce est plus étroite dans la direction latérale de la pièce que les deux parties dextrémité dans la direction longitudinale le long de la direction longitudinale sont agencées dans la direction latérale, et la conduite du transport à
