The paddles extend radially from the transport, and each paddle has a free end that is capable of supporting a web as the paddles move about the path. The free ends of the paddles are able to move towards each other to cause the web to corrugate. The ultrasonic welding device is located downstream to where the paddles' free ends move towards each other. The ultrasonic welding device has a horn and an anvil, and the anvil includes the free ends of the paddles.
