Abstract
An ultrasonic welding assembly is disclosed. The assembly includes a vibratory horn and at least one mount securing the horn. The horn has a resonant frequency and the mount has a resonant frequency about the same as the horn. The mount includes an inner portion that holds the horn at a nodal region. The mount also includes an outer surface that is coupled to a support member, for example, a bearing. The mount vibrates in resonance with the horn at the resonant frequency, wherein the vibration amplitude of the outer surface of the mount is generally up to about 15 percent of the vibration amplitude of the inner portion.
