Systems and methods using an ultrasonic transducer and scrubbing horn motion to seal a part

An ultrasonic welding system. The system includes an ultrasonic transducer assembly having a horn and a first transducer and a second transducer arranged to impart ultrasonic energy into the horn. The horn has a first part-interfacing surface and a second part-interfacing surface opposite the first part-interfacing surface. An actuator assembly is operatively coupled to the ultrasonic transducer assembly and configured to cause rotation of the horn. A controller is configured to: cause the actuator assembly to rotate the horn so that the first part-interfacing surface applies the ultrasonic energy to a first part along an entire length of the first part-interface surface while a first ultrasonic energy is applied through the horn via the first transducer to cause the first part-interfacing surface to vibrate back and forth along its entire length as the first ultrasonic energy is applied by the first transducer to the horn.

System and method for subjecting web to ultrasonic processing

An ultrasonic processing system adapted to subject a web running in a machine direction to ultrasonic processing includes a first mechanical element defined by one of an ultrasonic horn and an anvil and a second mechanical element defined by a remainder. The web placed on an outer peripheral surface of a rotary drum moves conforming to the drum in a machine direction. The first mechanical element is provided on the inner side of the drum and the second mechanical element is provided on the outer side of the drum. The first and second mechanical elements repeat a step of forward movement and a step of backward movement in a direction intersecting the machine direction across the web. In both steps, the first and second mechanical elements come in close contact with each other by the intermediary of the web and thereby subject the web to the ultrasonic processing.
