PROBLEM TO BE SOLVED: To form desired welds on a sheet member by reducing the influence of the rotary drive of a rotating drum which conveys the sheet member.SOLUTION: An ultrasonic welding apparatus forms welds on a continuously conveyed sheet member by applying ultrasonic vibration thereto. The ultrasonic welding apparatus includes: a rotating drum which conveys the sheet member by winding the sheet member on the outer peripheral surface thereof and rotating; an ultrasonic horn which generates ultrasonic vibration; an anvil which, together with the ultrasonic horn, clamps the sheet member in the thickness direction when the ultrasonic horn generates ultrasonic vibration towards the sheet member wound on the rotating drum; a first drive source which rotates the rotating drum; a second drive source which moves at least one of the ultrasonic horn and the anvil along the direction of the rotational axis of the rotating drum; and a control unit which independently controls the first drive source and the second drive source. |
