Abstract
An ultrasonic system and method for sealing a complex interface, such as a Gable top, having multiple and a variety of layers across the interface, or an oval or round spout having a complex geometry. The system includes two ultrasonic horns arranged opposite a gap between which the interface is provided. The frequency and phase of the ultrasonic energy are synchronized as the energy is applied simultaneously while the interface is pressed between a jaw and the energy is applied to both sides of the interface. Only one application of the frequency- and phase-synchronized ultrasonic energy is required to hermetically seal all the layers of the interface together.
