A method and apparatus are provided for sealing packaging material using ultrasonic technology. The method includes the steps of supplying the packaging material to a sealing station that includes an anvil and horn, and sealing the packaging material. The apparatus is a cam-shaped, rotatable anvil where the rate of rotation of the anvil can be changed based upon the speed of an AC Servo driving the anvil and the desired spacing between the seals.
