摘要： Provided is an ultrasonic sealing apparatus that forms a plurality of welded sections at intervals along a transport direction of a continuous web by applying an ultrasonic vibration to the continuous web while the continuous web is being transported along a predetermined linear track, the continuous web being related to an absorbent article. The apparatus includes an ultrasonic horn that emits the ultrasonic vibration; an anvil that cooperates with the ultrasonic horn so as to nip the continuous web in a thickness direction thereof while the ultrasonic horn is emitting the ultrasonic vibration towards the continuous web; and a reciprocating linear motion mechanism that moves the ultrasonic horn and the anvil along a forward path and a backward path which are parallel to the linear track. The forward path has an equal speed region in which the ultrasonic horn and the anvil oppose each other in the thickness direction and move at a speed value which is the same as a transport speed value of the continuous web. The ultrasonic horn and the anvil perform a nipping and a releasing of the nipping of the continuous web while moving in the equal speed region. The ultrasonic horn emits the ultrasonic vibration during the nipping of the continuous web.
