Abstract
The present welding system includes: a transport device that transports a work in a state where a plurality of webs are overlaid on each other; an anvil roller that includes an anvil which intermittently makes contact with the first surface of the work being transported; an ultrasonic horn that is opposite the second surface of the work and that cooperates with the anvil to apply vibration energy to the work so as to intermittently weld the webs; a speed changing device that lowers the transport speed of the work supplied between the horn and the anvil when the welding is performed; and a pressing device that presses the first surface of the work to the anvil when the welding is performed.
