Abstract
An ultrasonic apparatus and method for cutting a non-planar workpiece. The apparatus includes an anvil having a non-planar surface for closely engaging an underside of the workpiece. An ultrasonic horn has a non-planar cutting surface closely receiving a topside of the workpiece, wherein the cutting surface and the support surface have complementary non-planar shapes. The ultrasonic horn resonates at a predetermined frequency effect cutting of the workpiece. If the workpiece has a heat fusible component, the workpiece can also be seamed.
