Abstract
A ultrasonic processing method and apparatus (20), can include a rotatable, ultrasonic horn member (28) operatively joined to a first isolation member (42) and a second isolation member (44). In a particular aspect, the first and second isolation members (42, 44) can exhibit high rigidity. A rotatable anvil member (86) can be cooperatively positioned to provide a selected horn-anvil gap (106), and the anvil member (86) can be located in a horizontally offset and vertically overlapping arrangement relative to the horn member (28). An actuator (110) or other transfer device can selectively adjust the horn-anvil gap (106). Additionally, an ultrasonic exciter (82) can connect to the horn member (28), and can provide an operative amount of ultrasonic energy to the horn member (28).
