  • Sonic sealed bias seam
    Patent number: 6228195
    Abstract: A method and apparatus for forming an ultrasonic bias seam includes a rotary anvil disposed within a housing for rotation with the fabric being sealed. A selvage puller separates the selvage from the fabric. After sealing the fabric with the ultrasonic sealing head, the fabric is then cut in a spiral pattern at a predetermined angle. The resulting single-ply bias seam eliminates bulk, has a clean finished look and provides a completely sealed seam.
