Abstract
An ultrasonic welding device including a sonotrode having a central weld region adjacent to an anvil, a first converter providing mechanical vibrations to a proximal end of the sonotrode, a second converter providing mechanical vibrations to a distal end of the sonotrode in a direction opposite to the first converter, a power supply delivering electrical energy to each of the first and second converters, and the mechanical vibrations received by the sonotrode from the first converter being in phase with the mechanical vibrations received from the second converter.
