This invention pertains to methods and apparatus for processing workpieces, including effecting changes in the workpieces by applying ultrasonic energy to the workpieces using novel apparatus and steps for applying the ultrasonic energy to the workpieces. Specifically, an ultrasonic horn and anvil are used to apply ultrasonic energy in a limited amount, to effect change such as cutting in one layer of a workpiece without effecting a corresponding change in the other layers of the workpiece, although some change in the other layers may be tolerated and/or desired. A rotary horn and anvil are taught, with a protuberance on either the horn or the anvil. In use, the horn and anvil preferably rotate cooperatively in close proximity to each other at a nip, and apply pressure and corresponding ultrasonic energy to the workpiece only when the protuberance rotates into the nip, even though ultrasonic energy may be applied uniformly to the ultrasonic horn throughout the rotation of the protuberance. The workpieces may be presented to the horn/anvil combination as contained serially in a web of workpieces passing through the gap at a given speed; the speed of the protuberance being preferably substantially matched to the speed of the web while the protuberance is applying ultrasonic energy to a workpiece, but may differ from the speed of the web when the protuberance is not applying ultrasonic energy to a workpiece.
