1. A device for manufacturing an absorbent article having a plurality of granular particles capable of absorbing a body fluid between two liquid-permeable non-woven fabric sheets facing each other, the manufacturing device comprising:
an anvil roll for carrying the two non-woven fabric sheets while the two non-woven fabric sheets are laid on each other; a plurality of protruding portions formed on the anvil roll so as to protrude outward in a radial direction of the anvil roll; and a horn for ultrasonically vibrating so that the two non-woven fabric sheets are bonded together between the horn and the plurality of protruding portions, thereby forming bonded portions, wherein the anvil roll defines: at least one suction hole for drawing a first air, through the non-woven fabric sheets, together with the granular particles and the non-woven fabric sheets, so as to carry the non-woven fabric sheets and to prevent the granular particles from being placed on the non-woven fabric sheets over the protruding portions; and a ridge provided between the plurality of protruding portions and the suction hole, the ridge protruding outward in the radial direction of the anvil roll with a protruding height lower than a protruding height of the protruding portions, the ridge extending along an outer circumference of the suction hole. |
