A conventional welding technique for fabricating photoreceptor belts employs a ballscrew to drive an ultrasonic welder across the belt material. However, the ballscrew leaves its screw signature embedded in the weld seam. This pattern results in inconsistent weld seam roughness test results. This produces an increase in the amount of downtime and lost production time due to welder horn adjustments and excessive weld seam roughness testing. Moreover, the seam roughness test consistently shows a high test value due to the ballscrew pattern. Rough weld seams are undesirable since they can decrease the life of cleaner blades used in various copiers and printers.
