A continuing sheet and workpieces are appropriately adhered together. A device for manufacturing an absorptive article, the device comprising: a rotating member which has a circular arc-shaped holding surface for holding a workpiece and rotates while facing one surface of a moving continuing sheet, the rotating member being adapted to rotate while holding the workpiece on the circular arc-shaped holding surface, thereby moving the workpiece to a position at which the workpiece is sandwiched between said surface and the circular arc- shaped holding surface; and a pressing member which adheres the continuing sheet and the workpiece together by coming into contact, when the workpiece reaches the position at which the workpiece is sandwiched between said surface of the continuing sheet and the circular arc-shaped holding surface, with the other surface of the continuing sheet and pressing the continuing sheet toward the circular arc-shaped holding surface. The pressing member is a roller capable of freely rotating about the center axis thereof. When the roller makes contact with the other surface of the continuing sheet, the direction of the center axis of the roller intersects the direction of the center axis passing through the center of the circle of the circular arc-shaped holding surface. The line of intersection along which the outer surface of the roller intersects an imaginary plane containing the center axis of the roller is a circular arc-shaped curve, and the diameter of the roller at the center in the center axis direction thereof is less than the diameter of the roller at the ends in the center axis direction thereof.
Une feuille continue et des pièces sont collées ensemble de manière appropriée. L'invention concerne un dispositif pour fabriquer un article absorbant, ce dispositif comprenant: un élément rotatif qui comporte une surface de retenue en forme d'arc circulaire pour retenir une pièce, et tourne face à une surface d'une feuille continue mobile, l'élément rotatif étant conçu pour tourner en retenant la pièce sur la surface de retenue, de manière à déplacer la pièce en un point où celle-ci est prise en sandwich entre la surface de la feuille continue et la surface de retenue; et un élément de pressage qui fait coller la feuille continue et la pièce, quand la pièce atteint le point où celle-ci est prise en sandwich entre ladite surface de la feuille continue et la surface de retenue, en les mettant en contact avec l'autre surface de la feuille continue, et presse la feuille continue contre la surface de retenue. L'élément de pressage est un galet pouvant tourner librement autour de son axe central. Quand le galet entre en contact avec l'autre surface de la feuille continue, la direction de l'axe central du galet coupe celle de l'axe central passant par le centre du cercle de la surface de retenue. La ligne d'intersection suivant laquelle la surface extérieure du galet coupe un plan imaginaire contenant l'axe central du galet est une courbe en forme d'arc circulaire, et le diamètre du galet au centre, dans la direction de l'axe central, est inférieur au diamètre du galet à ses extrémités, dans la direction de l'axe central.
