摘要： An apparatus for joining a first film portion and a second film portion together along a seal line. The apparatus includes a horn and an anvil. The anvil is positionable in close proximity to the horn. Either the horn or the anvil has a face with a width dimension and a circumference and is rotatable about a rotation axis. The face has a raised profile, and a height of the raised profile has a dimension corresponding to 50% to 150% of a thickness of the first film portion or the second film portion. The face is positioned such that the raised profile extends along the circumference such that continuous running contact is provided between the raised profile and the other of the one of the horn or the anvil when rotated about the rotation axis, to form the seal line without any external structure to control a distance between the horn and the anvil.

摘要： A system includes a first horn, a first ultrasonic transducer, a second horn, a second ultrasonic transducer, a memory, and a controller. The first horn includes a first part-interfacing surface. The second horn includes a second part-interfacing surface and is positioned relative to the first horn such that a part to be welded can be positioned between the first and second part-interface surfaces. The controller is configured to cause a first ultrasonic energy to be applied through the first horn via the first transducer to cause the first part-interfacing surface to vibrate, cause the first horn to move in a first direction at a first time, cause a second ultrasonic energy to be applied through the second horn via the second transducer to cause the second part-interfacing surface to vibrate, and cause the second horn to move in a second direction at the first time.

摘要： 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.

摘要： An ultrasonic systems and methods for sealing complex interfaces or for metal forming. Complex interfaces, such as a Gable top, have multiple and a variety of layers across the interface, or an oval or round spout having a complex geometry. An example 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. Another example system includes two ultrasonic transducers synchronized in frequency and phase and used to vibrate a horn mechanically to facilitate a sealing or welding interface or to assist in a metal-forming process.
