Abstract
Abstract An ultrasonic seaming and cutting apparatus comprises a resonant horn, a rotating anvil wheel and a cutting surface disposed in juxtaposition with the anvil wheel. The cutting surface preferably is formed by a peripheral portion of a disk which is stationary, but incrementally rotatable to present selectively a new and sharp cutting surface to the horn. The wheel and disk are mounted for independent and resilient movement toward the frontal surface of the horn to accommodate different workpiece thicknesses and to reduce the wear apparent on the cutting surface.
