Abstract
Method and apparatus comprising a novel ramped anvil roll for cooperating with a rotary ultrasonic horn and creating ultrasonic bonds in a work piece passing between the anvil roll and ultrasonic horn. A relatively smaller radius portion of the anvil roll extends about a first portion of the circumference, and a relatively larger-radius raised bonding element extends about a second portion of the circumference. An outer surface at at least one of a front and rear end portion of the raised bonding element defines a transition gradient between the raised operating surface and the relatively smaller radius portion. The transition gradient defines a modified sinusoidally-shaped curved loading surface including an inflection locus, the curved loading surface representing a relatively constantly changing angle as measured against respective radii of the anvil roll in combination with advancing along the corresponding portion of the circumference.
