Abstract: A manufacturing apparatus for manufacturing an absorbent article, the manufacturing apparatus including: an upstream transport mechanism and a downstream transport mechanism that transports a stretchable sheet-like member along a transporting direction, the stretchable sheet-like member continuing along the transporting direction; an extension-ratio adjustment mechanism that is located between the upstream transport mechanism and the downstream transport mechanism, and that adjusts an extension ratio at which the stretchable sheet-like member extends in the transporting direction; and a processing apparatus that performs the certain process to the stretchable sheet-like member that is being transported by the downstream transport mechanism. When the upstream transport mechanism transports a first stretchable sheet-like member in which parts to be the absorbent article are lined up at a first pitch in the transporting direction, the extension-ratio adjustment mechanism adjusts an extension ratio of the first stretchable sheet-like member so that the parts to be the absorbent article are lined up at a predetermined pitch. When the upstream transport mechanism transports a second stretchable sheet-like member in which the parts to be the absorbent article are lined up at a second pitch in the transporting direction, the second pitch being different from the first pitch, the extension-ratio adjustment mechanism adjusts an extension ratio of the second stretchable sheet-like member so that the parts to be the absorbent article are lined up at the predetermined pitch.

Abstract: An ultrasonic processing system adapted to subject a web running in a machine direction to ultrasonic processing includes a first mechanical element defined by one of an ultrasonic horn and an anvil and a second mechanical element defined by a remainder. The web placed on an outer peripheral surface of a rotary drum moves conforming to the drum in a machine direction. The first mechanical element is provided on the inner side of the drum and the second mechanical element is provided on the outer side of the drum. The first and second mechanical elements repeat a step of forward movement and a step of backward movement in a direction intersecting the machine direction across the web. In both steps, the first and second mechanical elements come in close contact with each other by the intermediary of the web and thereby subject the web to the ultrasonic processing.
