Abstract
Apparatus for the ultrasonic sealing of plastic or metal containers which include a source of ultrasonic wave energy, an ultrasonic welding horn and an anvil. The ultrasonic welding horn is provided with means to adjust and make uniform the amplitude of vibration of the wave energy transmitted by the horn. This is accomplished by attaching weights of varying magnitude to the horn, thus assuring a uniform amplitude of the ultrasonic vibration across the face of the worksurface of the horn, to effect a uniform bond on a workpiece.
