Abstract
An ultrasonic processing method and apparatus (20) can include a rotatable, ultrasonic horn member (28) that is operatively joined to an isolation member (42) which has high rigidity. A rotatable anvil member (86) can be cooperatively positioned to provide a selected horn-anvil gap (106), and an automated drive (130) can be connected to an actuator (110), or other transfer device, to automatically adjust the horn-anvil gap (106). An electronic processor (128) can be configured to monitor an intermittent gap force detected from an output provided by a force sensor (126), and can provide a drive signal to the automated drive (130) to thereby adjust the horn-anvil gap (106) to operatively maintain a target, gap force value.
