ABSTRACT:
An object of the present invention is to provide a welding system wherein the positional accuracy of welding and the quality of welding are improved. The present welding system includes an ultrasonic welder for welding a plurality of webs W together while carrying the webs W. The ultrasonic welder includes: an anvil roller10including a pair of anvils11, 12; a first ultrasonic horn21and a second ultrasonic horn22that apply vibration energy to the webs W in cooperation with the pair of anvils11, 12. The pair of anvils11, 12are provided symmetrically with each other with respect to an axis line O of the anvils roller10. The first and second ultrasonic horns21, 22apply the vibration energy to the webs W simultaneously while each of the anvils11, 12faces the first or second ultrasonic horn21, 22.
