Abstract
This invention pertains to apparatus and methods for creating ultrasonic bonds in sequentially advancing absorbent article workpiece segments, in a bonding nip. The ultrasonic bonding apparatus comprises a frame, anvil support apparatus, horn support apparatus, closure apparatus, a load cell support member, and a load cell. The ultrasonic horn and the anvil roll collectively are mounted and configured such that the ultrasonic horn and the anvil roll can be brought together, via the closure apparatus, to define the nip therebetween. The load cell is mounted to the load cell support member such that force representative of force exerted on the anvil roll at the nip is detected by the load cell. In preferred embodiments, the invention includes outputting information from the load cell and adjusting force in the nip in response to the information received from the load cell.
